Environmental scan
Pain is a necessary part of our normal physiology. It prevents tissue damage and causes
behavioural and physiological changes to facilitate tissue repair. However, for an
unfortunate few, pain can create debilitating unbearable suffering. For the majority, pain
is not a medical challenge. For the few it is. Pain is heterogeneous in terms of aetiology,
mechanisms and temporal characteristics, making it difficult to study other than through a
multidisciplinary approach focussed on selected types of pain. Also, it is clear that there
is no “magic bullet” to treat all types of pain. What is needed is to understand that
different types of pain exist (Woolf & Salter, 2000), the distinguishing properties of each
type (Schulz & Woolf, 2002) and an understanding of the mechanisms underlying each
type (Hunt & Mantyh, 2001; Decosterd et al, 2004). If we are to develop novel
interventions to treat chronic pain it is imperative to find the specific molecular targets of
different pains (Honore et al., 2000). Concepts of mechanisms also need to be partnered
with emerging views from genetics, genomics and proteomics of pain (Mogil &
McCarson, 2000; Mogil, 2004). Demographics indicating an ageing population
accentuate this need for innovative interventions to treat chronic pain (Gibson & Farrell,
2004); as the mean population age increases, the incidence of chronic diseases such as
rheumatoid arthritis, osteoarthritis, diabetes and others, all sharing the symptom of
debilitating chronic pain, are expected to skyrocket, and with them the need for effective
pain management (Ferrell, 2004).

Leadership
James L. Henry, Ph.D.
Scientific Director
Dr. Henry, a neurophysiologist who has
worked throughout his career to understand
underlying mechanisms of chronic pain, is the
inaugural scientific director of the Michael G.
DeGroote Institute for Pain Research and Care
at McMaster University. He also holds an
endowed chair in central pain.
Joining McMaster in January 2005 as a
professor in the departments of Psychiatry and
Behavioural Neurosciences and Anesthesia, he
is also renowned for important advancements
in basic science of pain, his strong record of
leadership, and his training of young
investigators.
Dr. Henry earned his doctorate in physiology from the University of Western Ontario in
1972 and received postdoctoral fellowships from the Canadian Medical Research Council
and Le Conseil de la recherche en santé du Québec. In 2000 he was awarded the
Millennium Distinguished Career Award of the Canadian Pain Society.
From 1977 to 2002 he was a professor in the Department of Physiology at McGill
University. He established both the McGill Centre for Research on Pain and the Quebec
Pain Research Initiative which networks pain researchers and clinicians across Quebec.
From 2002 to 2004, he was professor and chair of the Department of Physiology and
Pharmacology at the University of Western Ontario.
His research has a focus on control systems within the central nervous system. He is
world renowned for his pioneering discovery, in 1975, that the peptide, substance P, is a
regulator of synaptic transmission in central pain pathways, specifically in the region of
the first sensory synapse in the spinal cord and brain stem. This discovery opened a new
field of research into the neurochemistry of pain mechanisms and led him to propose a
chemical specificity theory of pain that replaced previous theories of pain and which
persists unchallenged today.
His awards over the past ten years include the Millennium Distinguished Career Award
of the Canadian Pain Society (2000), the Raymond W Houde Memorial Award of the
Eastern Pain Society, New York (2006) and the Gunn-Loke Lecture, Multidisciplinary
Pain Center, University of Washington (2008).

Osteoarthritis Pain Research
Artist depiction of life with osteoarthritis pain.
Osteoarthritis – what is it?
•
•
Osteoarthritis is a degenerative joint disease and is the most prevalent form of
arthritis
Osteoarthritis is the leading cause of disability (MMWR Morb Mortal Wkly Rep.
50 (7): 120–5)
What is its impact?
• approximately 10% of Canadian adults are afflicted with osteoarthritis (Health
Canada, 2003).
• pain is reported to be what causes patients with OA to seek medical attention
(Creamer et al., 1998)
• the primary goal of current management of the patient with OA remains
control of pain along with improvement in function and health-related quality
of life (Felson, 2005)
• there is poor correlation of OA pain with radiographic and other signs in OA,
such as loss of cartilage and bony changes (Lethbridge-Cejku et al., 1995)
• effectiveness of existing drug therapies for OA pain is poor, with only
moderate effectiveness (Wieland et al., 2005)
• patients with OA are faced, then, with limited treatments that have a known
mechanistic basis of action
• significant resources are being applied to limiting cartilage loss and alterations
in bone structure, but until recently, there has been little basic science
investigation focused on understanding the mechanisms underlying the
initiation and the maintenance of the pain of OA
Page 13 of 52
What are we contributing?
• studies to address the lack of mechanism-based treatments
• several mechanisms of OA pain have been proposed, but none accounts for
o lack of correlation of functional and structural change
o referred nature of OA pain
o loss of proprioception
• we have established a unique animal model of OA pain
o confirmed in histological, anatomical, imaging and physiological
studies
• have found that joint use exacerbates joint pathology
• have identified changes in gene expression in OA knee
• studying changes in gene expression in sensory neurones
• recording from spinal nociceptive neurones
o data indicate that the spinal substrate of nociception undergoes loss of
buffering capacity
• recording from primary afferent neurones
o data indicate that the primary pathology is not in normally nociceptive
neurones, but that large diameter non-nociceptive neurones undergo a
phenotypic change and relay a ‘pain’ signal to spinal nociceptive
neurones
• on the basis of our results we are proposing a new hypothesis of OA pain: that
encompasses all symptoms associated with OA and departs from all earlier
hypotheses on mechanisms of OA pain
• involved in commercial development of novel compounds for treatment of
OA pain

Peripheral Neuropathic Pain Research
“Pain is a major healthcare problem in Europe. Although acute
pain may reasonably be considered a symptom of disease or
injury, chronic and recurrent pain is a specific healthcare
problem, a disease in its own right”
European Federation of IASP Chapters
“Ten years following the initial neck injury I painted this self-portrait; a study in the
unceasing coldness that set in after surgery and the continuing awareness of the area of
surgery, a self-consciousness about the resulting scar and the residual pain. This is
despair and resignation combined with a determination that saw me through many years
of surgeries and pain and treatment yet to come. ”

Peripheral neuropathic pain – what is it?
•
•
peripheral neuropathic pain is due to damage or dysfunction to the peripheral
nervous system
types of peripheral neuropathic pain include: painful diabetic neuropathy, postherpetic neuralgia, post-amputation pain, HIV-related neuropathies,
chemotherapy-related neuropathies, complex regional pain syndrome, traumatic
and compressive nerve injuries, nerve tumours including neuromas, trigeminal
neuralgia, syringomyelia, failed back surgery syndrome, traumatic brachial plexus
injury,
What is its impact?
•
•
•
•
as much as 7% to 8% of the of the population is affected by neuropathic pain and
in 5% it may be severe
neuropathic pain is associated with a number of other comorbdities, including
depression, sleep disorder and development of other types of pain, and is a major
contributor to absenteeism and decreased productivity at work
neuropathic pain is relatively refractory to medical treatment, with only 50% of
patients achieving even modest pain relief
mechanisms underlying peripheral neuropathic pain are unknown
What are we contributing?
• studies undertaken to address the lack of mechanism-based treatments
• we have been running a unique animal model of peripheral neuropathic pain
• measuring influence of neuronal dysfunction on pathology of peripheral tissues
• reflex testing using standard tests of
o tactile hypersensitivity
o mechanical hyperalgesia
o cold place preference test
o differential weight-bearing test
• recording from spinal nociceptive neurones
o data indicate that the spinal substrate of nociception undergoes increased
excitation to noxious and innocuous stimuli
• recording from primary afferent neurones
o data indicate that the primary pathology is not in normally nociceptive
neurones, but that large diameter non-nociceptive neurones undergo a
phenotypic change and relay a ‘pain’ signal to spinal nociceptive neurones
• mechanisms implicated specifically from our studies indicate substance P and
other structure-related chemical pathways in peripheral neuropathic pain
• on the basis of our results we are proposing a new hypothesis of neuropathic pain
that pain is due to mechanisms that evolve over days, giving a therapeutic window
of “a golden day and a silver week”, after which the pain will be difficult to treat
• involved in commercial development of novel compounds for treatment of
peripheral neuropathic pain

Bone cancer pain – what is it?
•
•
•
•
•
•
bone cancer pain most commonly occurs when tumors originating in breast,
prostate, or lung metastasize to long bones, spinal vertebrae, and/or pelvis
bone pain is commonly the first symptom of bone metastases and may lead to
tests that will confirm the diagnosis
primary and metastatic cancers involving bone account for an estimated 40,000
new cancer cases per year in Canada
>70% of patients with advanced breast or prostate cancer have skeletal metastases
pain resulting from bone cancer can dramatically impact an individual’s quality of
life
generally two major components to bone cancer pain
Page 25 of 52
•
•
•
o an early dull ache or throbbing in character, usually ongoing and increases
in severity over time
o a later breakthrough or incident pain occurs either spontaneously, with
intermittent exacerbations of pain, or by movement of the cancerous bone
- one of the most serious and highly debilitating sequelae of cancer and
one of the most difficult cancer pains to treat
radiotherapy remains the cornerstone for the treatment of bone cancer pain, it is
most effective for the symptomatic treatment of local bone pain but is
accompanied by severe adverse effects
control of breakthrough pain can be problematic because doses required are
usually high and accompanied by adverse side effects such as severe cognitive
impairment, sedation, and constipation
little is known about the mechanisms that generate and maintain this pain
What is its impact?

Iconic Pain Assessment Tool
It is said that few die from pain; yet many die in pain and even more live in pain.
What is the Iconic Pain Assessment Tool?
• unlike other major health disorders, there is a general lack of objective
measures for pain, particularly chronic pain
• we are reliant on translation tools for the accurate and efficient
interpretation of patient experience, which must operate within a userfriendly framework and demonstrate the properties of validity,
reliability, and patient adherence
• an ideal pain assessment instrument should:
o provide a quantitative measure for analysis
o capture the different qualitative dimensions of pain
o be free from reliance on linguistic competence
o be related to the patient’s disease experience

Community Alliances for Health Research and Knowledge
Translation in Pain
This is a research project in knowledge translation funded by the CIHR Institute of
Musculoskeletal Health and Arthritis and the CIHR Institute of Neuroscience Mental
Health and Addiction.
Clause 4 of Bill C-13, the CIHR Act of the Canadian Parliament states:
“The objective of the CIHR is to excel, according to internationally accepted standards
of scientific excellence, in the creation of new knowledge and its translation into
improved health for Canadians, more effective health services and products and a
strengthened Canadian health care system …”
Research generating knowledge in pain is attempting to understand mechanisms,
complexities, incidence and prevalence, the personal, social and economic costs, etc.
While much remains to be learned, at the same time we must recognize that we are much
further ahead than we were 20 years ago, even 10 years ago. An important question,
though, is how much this mounting knowledge is being applied to those who suffer
debilitating pain, which is the presumed end-purpose of knowledge generation. This is
the entry point for ‘knowledge translation‘, the term widely used to refer to the process of
research use, or the application of knowledge to receptor communities. More formally,
knowledge translation at CIHR is defined as the exchange, synthesis and ethically sound
application of research findings within a complex set of interactions among researchers
and knowledge users - to accelerate the capture of the benefits of research for Canadians
through improved health, more effective services and products, and a strengthened health
care system.
Canada, the Canadian health care system, Canadian society and the Canadian economy
are in dire need of application of knowledge translation and exchange to debilitating pain.
In fact, a national strategy is needed to promote implementation of research findings,
Page 37 of 52
application and appraisal of clinical practice guidelines, and uptake of decision support
tools by health care practitioners and decision-makers.
What we are doing about it?
CAHR-pain is a Canadian research network funded by the Canadian Institutes of Health
Research to provide knowledge translation to receptor communities in the area of pain.
The six themes are each led by internationally-recognized leaders in the field, and you are
invited to learn about what each theme has as its research objectives, who the participants
are in each research theme, what the respective receptor communities are, what the longterm objectives are and how these will be carried out. This information is available by
clicking on the respective section of this web site.
The overarching impact from the outputs of this CAHR is to promote and sustain a
balanced portfolio of curiosity-based and needs-based research, which along with
existing knowledge will be mobilized and applied for the benefit of Canadians, the health
system and the economy.
The value-added of the CAHR is as follows:
• Creation of a unified stakeholder voice to make recommendations for public and
voluntary sector policy development to address the huge burden of chronic pain
• Creation of the defensible case for research-community interactions in this
domain to ensure that reliable knowledge addresses burden by being socially
robust
• Enhancement of the funding base supporting operations and, on this basis,
potential for leverage from the public purse, for incremental funding
Chronic pain as a chronic disease
Page 38 of 52
The burden of chronic diseases is tremendous, and traditional methods of healthcare
delivery are unsuitable for addressing these needs. Chronic disease management has
emerged as a new strategy for chronic disease care. Chronic disease management in the
clinical setting is defined as an organized, proactive, multi-component, patient-cantered
approach to healthcare delivery that involves all members of a defined population who
have a specific disease entity (or a subpopulation with specific risk factors). Care is
focused on, and integrated across the entire spectrum of the disease and its complications,
the prevention of comorbid conditions, and relevant aspects of the delivery system.
Essential components include identification of the population, implementation of clinical
practice guidelines or other decision-making tools, implementation of additional patient-,
provider-, or healthcare system-focused interventions, the use of clinical information
systems, and the measurement and management of outcomes.
The European Federation of IASP Chapters (International Association for the Study of
Pain) views chronic pain as a disease, and they have successfully lobbied the European
Parliament to declare chronic pain as a disease.
“Pain is a major healthcare problem in Europe. Although acute
pain may reasonably be considered a symptom of disease or
injury, chronic and recurrent pain is a specific healthcare
problem, a disease in its own right”
Who is involved?
The following are key leaders in the CAHR-pain initiative:

Page 39 of 52
An overview of the mandates of the respective Research Themes is as follows:
CAHR-pain will build capacity integrating community through to decision, as a state of
readiness to partner with process to improve the quality of life of those living with the
burden of chronic pain. At a national meeting in 2006 that included academics, clinician
researchers, pain management professionals, patients, epidemiologists, experts in KT,
health economists and industry representatives, it was agreed that to make meaningful
progress action must be taken to address the quality care gap for the one in five
Canadians suffering chronic pain. This initiative will create a favourable environment to
drive innovation in KT directed at improving measurable outcomes through six Research
Themes within three operating principles.
Research Theme 1 – “From the Ground Up: Alliances to Address Chronic Pain in the
Community”. This Theme will engage communities of chronic pain sufferers and
families, providers of health care and relevant organizations in participatory action
research to explore the chronic pain experience, the interface of chronic pain
patients/families with the health system, the needs of people with chronic pain, and
perspectives about client, provider and system expectations regarding care. We will
conduct an in-depth review of the scientific, policy and lay literature to identify existing
resources and emerging technologies for both patients and providers of care, and best
practice and models of community-based care for chronic pain
Research Theme 2 – “E-learning interprofessional pain curriculum for pre-licensure
health science students”. The overall objective is to improve the health of Canadians
who are experiencing pain, through the development and evaluation of an E-learning pain
curriculum for pre-licensure health science students in universities across Canada. This
study will be developed to: develop an E-learning pain curriculum for pre-licensure
health science students; evaluate its transferability to pre-licensure health science students
in selected universities across Canada; develop KT strategies for implementation of this
curriculum in each site, including facilitator training; implement a pilot study to evaluate
the final curriculum product.
Research Theme 3 – “Preceptorship Programmes in Pain Management - Longitudinal
Evaluation of Pain Management Education in Medical Trainees through Undergraduate
and Post Graduate Programs and Creating Pain Management Clinics Practicing EvidenceBased Standards of Care”. The present research project is to: intervene at different levels
of the career development of physicians and other health care practitioners to measurably
improve the skills and competencies in pain management both locally and nationally;
measure the impact of our various preceptorship programs on the physicians that we
educate, particularly in the field of Pain and Addiction; demonstrate that pain clinics can
follow acceptable standards of care and document that these standards of care were
influenced by this training.
Research Theme 4 – “Partnering with the Alberta HTA Chronic Pain Ambassador
Programme”. The project team is committed to evaluating the impact of the
“Ambassador Workshop KT Strategy” on: provider knowledge of evidence-based
assessment and treatment strategies; provider clinical practices/activities when working
with patients with these symptoms; patient outcomes. The results of the initial study will
Page 40 of 52
be used to plan a two group cluster randomized trial and additional cluster randomized
controlled trials comparing the Ambassador program to other promising knowledge
translation strategies.
Research Theme 5 – “Integrating Evidence into Effective Collaborative Practice to
Enhance Quality of Life”. The objective is to apply innovative KT strategies engaging
the chronic pain community to effectively mobilize explicit and tacit knowledge to assist
those living with chronic pain to attain the best possible quality-of-life. We will develop
and evaluate: a push-out technology (MacPlus-P) to capture and push-out the best
evidence on management of chronic pain to clinicians, patients and policy makers; a
Community of Practice approach to mobilizing the tacit knowledge required to
implement best practice in chronic pain management (including community-based and
knowledge developed in our Themes / groups).
Research Theme 6 – “Engaging in Knowledge Translation Through Deliberative
Processes”. The project team proposes: to develop and test a simple tool to describe and
evaluate key elements of deliberative processes that bring together public policymakers,
health system managers, clinical leaders, consumer group representatives and others to
discuss key challenges in responding to chronic pain (e.g., goals, group composition, and
group process); and to conduct formative evaluations of all deliberative processes and
after two and four years a summative evaluation of a concerted effort to match key design
elements to particular contexts.

Community Outreach – Health Care Professionals
“Who understands pain, knows medicine”
–Sir William Osler
Rationale:
Pain imposes a heavy burden on health care services across the board. The 1994-1995
National Population Health Survey indicated that 3.9 million Canadians, or 17% of the
population over the age of 15, suffer chronic pain. Sadly, though training in pain
management is barely alluded to in most health professional training programmes
(veterinarian trainees are reported to average five times more training than the average
for physician trainees). Although 40-65% of visits to family physicians have a pain
component, patients typically report that communication with doctors is poor. In a study
that attempted to quantify the total cost of chronic non-cancer pain to the Irish economy
in 1995, a study from a sample of 95 patients estimated that chronic pain had already cost
the economy £1.9 million by the time of their referral to a multidisciplinary pain clinic.
A reportedly high use of specialist care by chronic pain patients has been attributed to the
absence of a functioning primary care gate-keeping system for patient selection.
Management of low back pain in a cohort of general practitioners in Ireland was not
consistent with European clinical guideline recommendations and it was found that most
of the costs incurred by the National Health Services were attributable to physician nonadherence. The information in this paragraph is presented in detail in Henry, Pain
Research & Management (in press) 2008.
Clearly, knowledge translation to health care professionals remains a high priority if we
are to address the needs of those who live with chronic pain.
Goals:
The principal goal of the community outreach to health care professionals is to address
the gap between evidence and practice. A secondary goal is to create visibility and
credibility of the Michael G. DeGroote Institute for Pain Research and Care as a leader in
continuing health education in chronic pain.
What are we contributing?
This initiative is addressing knowledge translation to family physicians, specialists,
nurses, nurse practitioners, physiotherapists, pharmacists and other interested
professionals. In particular, Continuing Health Education Courses are being held to
address issues facing health care professionals vis a vis chronic pain management.
Topics in these courses have covered early and effective assessment, dealing with the
complex patient, use and abuse of opioids in pain management, focus on rehabilitation
and life habits, cannabinoids as drug or weed, the multidisciplinary approach to pain
management, addiction and drug-seeking vs. the bone fide need, alternative approaches to
Page 43 of 52
pain management, interrelation of the family physician and the pain clinic, nonpharmacological approaches to pain management, interprofessional interaction, etc.
To carry out this programme a series of continuing health education events has been held
each year since the first year of the National Pain Awareness Week in 2005.
Participation in these courses has consistently drawn 80 to 110 from across the health
care spectrum. Distinguished speakers have been attracted to the Hamilton/Burlington
area nationally and internationally to provide fertilisation of local health care
professionals with new and advancing ideas.
The annual Academic Pain Day poster for 2008 is found on the next page.
In addition, continuing health education courses have been offered during the Global Day
Against Pain, as declared collectively by the World Health Organization and the
International Association for the Study of Pain (IASP).
Other continuing health education courses have been held at other times throughout the
year.
These events have been made possible largely through industry partners and the Ontario
Pain Foundation, which was established to promote educational activities in the local
community.
These events and courses have been organized and run by Dr. Kiran Yashpal and Dr.
James L. Henry.
In 2006 the Michael G. DeGroote Institute for Pain Research and Care held an two and a
half day international meeting in Toronto on central neuropathic pain. This attracted the
thought leaders on central neuropathic pain from around the world. Funding was
provided from the IASP as that year’s IASP Research Symposium, as well as funding
from a number of industry partners. Attendance included mainly researchers and
physicians and the programme provided an update on mechanisms, diagnosis and
management of central neuropathic pain, particularly central post-stroke pain. The
proceedings were published as a book and circulated widely by the IASP Press.

Community Outreach – Chronic Pain Patients
“Knowing is not enough; we must apply.
Willing is not enough; we must do.” - Goethe
“This sculpture symbolizes being trapped by chronic pain. The
rebar represents a prison and I am attempting a desperate escape
by pushing my face through the bars but there is never an escape.”

Rationale:
In 2005 a patient support group was established in the Hamilton/Burlington area. The
first thought of doing so came from a chronic pain patient performance in Toronto, based
on stories of patients who were associated with the Wasser Pain Management Centre in
Mount Sinai Hospital in Toronto, directed by Dr. Allan Gordon. It was apparent that
patients needed to express themselves, they had stories to tell and they gained benefit
from being and working together.
It became clear that traditional health care delivery was important and critical to these
patients and that self-management courses were also important. However, beyond these
Page 46 of 52
it appeared to us that socializing with peers was also important. This is not offered by
other resources and it was decided to establish the local group. To achieve this, we set up
a vehicle to fund these activities, the Ontario Pain Foundation; with a Board of Directors
and an accounting firm to ensure compliance, the OPF functions to promote educational
activities in the local communities. Reference to some of these activities is made in the
previous section on CHEs.
Goals:
The principal goal of this initiative is to create community alliances for health research
and knowledge translation in pain, engaging all stakeholders with an interest in chronic
pain. A secondary goal is to create visibility for the Michael G. DeGroote Institute for
Pain Research and Care as a community leader in the cause against chronic pain.
What are we contributing?
Initially, we worked with the Chronic Pain Association of Canada to incorporate
established principles to set up a support group with a catchment area including Hamilton
and Burlington, although some patients have come from Kitchener/Waterloo, Brampton,
Mississauga and the Niagara/St. Catharines area.
The group has monthly meetings, on Tuesday nights. Each event includes a period of
social networking. In addition, meetings include invited speakers of special interest to
chronic pain patients. Past speakers have included topics such as the physician approach
to chronic pain, physiotherapy for chronic pain, principles of nutrition to lessen the
burden of pain, principles of tai chi for those who suffer chronic pain, massage therapy
for pain, natural healing approaches to lessen pain, the ins and outs of pharmaceuticals
for pain, a programme in self-management for chronic pain, the science behind pain,
traditional Chinese medicine for chronic pain, etc. Many meetings also have
entertainment to lighten the atmosphere.
In addition, the group is assembling stories of what it is to live with chronic pain and of
their experiences with the health care system, the legal system, the insurance system as
well as family and friends.
An annual Public Forum is also held. In this case, in addition to the social networking
there are invited speakers and exhibits of community organizations that relate to chronic
pain. For example, this year invited speakers include the President of the Canadian Pain
Coalition, the national organization of support groups and chronic pain sufferers, and a
physician who also suffers chronic pain. Community organizations include those
offering services to chronic pain sufferers.
The Ontario Pain Foundation has also sent representatives of this support group to the
Annual Meeting of the Canadian Pain Society to interact with a broader community of
stakeholders and to bring back their own experiences to the group.
These activities have been organized by Drs. Kiran Yashpal and James L. Henry.

McMaster as a Centre of Culture of Pain Research
The generous gift to McMaster from Mr. DeGroote gave birth to the possibility of
creating a world-class pain institute. To create such an institute it has been necessary to
introduce to McMaster and Hamilton Health Sciences a culture of pain research. None
had existed before. An advantage was that previous models existed at the time in
Toronto and Montreal, and recruitment of the Scientific Director brought direct
experience with creating a culture of pain research and a track record of success in doing
so.
In particular, a strategy was pursued to generate this culture from existing strengths. For
example, the CIHR project on Community Alliances in Health Research, CAHR-pain,
has enlisted the following researchers at McMaster in a unique blend of expertise,
creating a McMaster team of 8 researchers to include Drs. Brian Haynes, John Lavis,
Anthony Levinson, Joy Macdermid, Patty Solomon, Jean-Eric Tarride, Linda
Woodhouse.
In addition, a number of other research projects have been launched to create a pain
research culture from existing strengths. These include the following McMaster
researchers.
Dr. Alexander Ball is collaborating on immunohistochemical studies on
intracellularly-labelled dorsal root ganglion neurones in an entirely unique
technical approach to understanding mechanisms of the pain of osteoarthritis.
Drs. Norm Buckley and Akbar Panju – To 2007 I co-supervised a graduate
student to develop an internet-based pain assessment tool for central post-stroke
pain. This tool is found at the following URL:
http://www.emiliemcmahon.ca/mrp.html - together with Drs. Buckley and Panju,
we completed a research project, beginning with a summer student project last
summer, to determine the most appropriate receptor community for this tool and
then to refine the tool for these end users and monitor its uptake and effectiveness
for patients and managers of central post-stroke pain. Ultimately, this tool will be
broadened for application to other types of chronic pain.
Dr. Margaret Fahnestock has been collaborating on a study of the involvement
of brain-derived neurotrophic factor (BDNF) in mechanisms of altered
nociceptive mechanisms in the spinal cord of our animal model of osteoarthritis.
Dr. Jan Huizinga is collaborating on a highly technical and unique project. In
this case, we will be recording intracellularly from single dorsal root ganglion
neurones and classifying these neurones in terms of their electrophysiological and
physiological properties. Each neurone will be individually filled by intracellular
injection of a cellular marker. The ganglion will be removed, the neurones
dispersed and the filled neurone will be extracted. This neurone will then be
analyzed using RT-PCR to determine changes in expression, particularly of ion
channel species. This is because of some unique observations we have made that
have led to a new and transformative hypothesis that explains how osteoarthritis
Page 48 of 52
pain is brought about and how this type of pain remains refractory to medical
treatment. The plan is to carry out pilot experiments and submit a joint grant
application for this project.
Dr. Wolfgang Kunze is collaborating on another highly technical and unique
project. We will be recording intracellularly from single dorsal root ganglion
neurones and classifying these neurones in terms of their electrophysiological and
physiological properties. Each neurone will be individually filled by intracellular
injection of a visible dye, the ganglion removed and placed into an in vitro
recording chamber. The neurone will then be re-visualized and recorded from
using patch clamp technology to determine the ion species underlying the changes
in excitability and neuronal properties identified in our osteoarthritis model. The
plan is to carry out pilot experiments and submit a joint grant application for this
project.
Dr. Carl Richards – Our collaboration focuses on molecular mechanisms of
inflammation and pain in osteoarthritis, using our derangement rat model of
osteoarthritis. Based on some of our recent data, our laboratory is proposing that
the pain of osteoarthritis arises from a demyelination process in peripheral nerve
fibres, and this collaboration is directed at determining the role of cytokines and
cytokine receptors in this process, including the breakdown of the connective
tissue matrix that insulates these fibres and also provides the basis for saltatory
conduction in these fibres, and that shares a symbiotic metabolic relationship with
nerve fibres.
Dr. Gurmit Singh is collaborating on a study on an animal model of bone cancer
pain. The project involves running physiological nociceptive reflex tests on these
animals and running unique operant behavioural tests to measure the level of pain
experienced. This model will be used to identify novel targets for development of
new and effective treatment of bone cancer pain. A new graduate student has
been taken on for this project.
Dr. Linda Woodhouse is collaborating on a study to develop a unique animal
model of axial pain. Most animal models pertain to distal pains, yet the most
common of the debilitating pains is axial. In this study we are expanding on the
joint derangement of the osteoarthritis model and modifying an existing spine
immobilization model to create a flexible derangement model of vertebral pain.
This study also involves Dr. Kiran Yashpal as well as Drs. Barry Sessle and
James Hu, of the University of Toronto, and Dr. Howie Vernon, of the Canadian
Memorial Chiropractic College. The plan is to carry out pilot experiments and
submit a joint grant application for this project.
