CASE STUDY Outcome of Chiropractic BioPhysics® (CBP®) Protocol on a Patient with Tourette¶s Syndrome, Tardive Dyskinesia, CREST Syndrome, and Fatigue Marco Ferrucci, B.S. D.C.1, Abe Cardwell B.A, D.C.2, Deed E. Harrison, D.C.3 __________________________________________________________________________________________ ABSTRACT Objective: To present a case of Chiropractic BioPhysics (CBP) protocol of care used on a patient with fatigue, Tourette¶s syndrome, tardive dyskinesia, and Calcinosis, Raynaud¶s, Esophageal thickening, Sclerodactyly, and Telangiectasia (CREST) syndrome. Clinical Features: A 45-year-old male with a history of fatigue, Tourette¶s syndrome, tardive dyskinesia, and CREST syndrome presents to a CBP chiropractic office. The patient stuttered while he spoke and had an uncoordinated stagger as he walked. The patient had tremors in his arms and hands. Postural analysis and A-P cervico-thoracic x-ray showed a 16 right lateral tilt of C5-T4 segments relative to vertical, a 20 left cervico-dorsal (mid-neck scoliosis) angle, a 22mm right lateral translation of C2 relative to T4. Lateral cervical showed a 20 cervical lordosis with a 20 atlas plane angle. All measurements were based on CBP® protocol for x-ray line drawing. spine and postural subluxations, in addition to a 7mm heel lift for his right shoe. The patient was seen 3 times a week for the first 12 weeks then was seen 2 times a week thereafter for a year. After a few months of care the patient¶s wife reported improvements in his energy level and that the tremors were decreasing. After a year of care the patient was markedly improved. Follow-up radiograph showed a C5-T4 lateral tilt angle to vertical of 5 to the right (an 11 improvement), the cervico-dorsal angle was 8.5o to the left (11.5o improvement), and the lateral translation of C2 relative to a vertical line up through the center of T4 vertebra was 6mm to the right (16mm improvement). Conclusion: Reductions of the patient¶s abnormal posture and radiographic spinal subluxations using CBP protocol of care may have been responsible for improved neurological issues such as Tourette¶s syndrome, tardive dyskinesia, CREST syndrome, and fatigue. Key Words: Chiropractic BioPhysics (CBP), vertebral Interventions and Outcomes: The patient received CBP care over a 12-month period receiving approximately 108 treatment subluxation, chronic fatigue, Tourette¶s syndrome, tardive sessions. Mirror image® adjustments, mirror image exercises, dyskinesia, CREST syndrome, chiropractic adjusting, postural and mirror image traction were used to reduce the patient¶s adjusting, mirror image. ____________________________________________________________________________________________________________ Introduction Tourette¶s Syndrome (TS) is one of several tic disorders, which can be characterized by either their type or duration.1 There could be motor or phonic types and may be transient or chronic in duration. A transient tic would be anything of duration less than 12 months whereas chronic tics would have durations more than 12 months. 1. 2. 3. Private Practice ± Nutley, NJ Private Practice ± Marietta, GA Private Practice ± Spring Creek, NV Biophysics If both vocal and tonic tics are present for more than 1 year then the diagnosis of Tourette¶s syndrome is appropriate. 1 Individuals with chronic tic disorders often describe a premonitory sensation prior to the tic occurring.1 The sensation may build as the individual tries to suppress it. The performance of the tic is associated with a momentary relief of the sensation. This characteristic of TS makes it very similar to obsessive-compulsive disorder, or OCD. Therefore, many suggest that OCD and TS may share a common genetic J. Vertebral Subluxation Res.

The movements are involuntary and characterized by abnormal, repetitive, , and may be around the mouth, face and less frequently the trunk and limbs. 3 The severity of TD may fluctuate over time; in some cases there may be improvement and others there may be increase from medium to long-term symptoms. The cumulative risk of TD seems to increase as treatment of the anti-psychotic medications continues. 4 Conventional antipsychotics may induce TD through prolonged D2 receptor blockade, postsynaptic dopamine hypersensitivity, damage to gammaaminobutyric acid (GABA) neurons and damage to cholinergic neurons. 4 Whereas atypical anti-psychotics may decrease dopamine sensitivity, these may be less likely to cause damage to GABA neurons or cholinergic neurons. 4 Calcinosis, Raynaud¶s, Esophageal Thickening, Sclerodactyly, and Telangiectasia (CREST) syndrome is commonly seen in scleroderma patients. Scleroderma is an autoimmune disease influenced by the interplay of genetics and environmental factors such as stress. 5,6 This disease has frequently been helped by complementary and alternative medicine (CAM) interventions;6 thus, it may be that this condition could be improved through chiropractic care. symptoms including cognitive deficits, bladder dysfunction, leg weakness and parenthesis in her arms and legs. Her symptoms progressively worsened without remission and she was diagnosed with chronic progressive MS and recommended drug therapy (Avonex). Upon chiropractic evaluation, there was evidence of radiographic verified upper cervical subluxation. The patient was adjusted using the kneechest table where adjustment was administered by hand to the first cervical vertebra. The patient was seen under upper cervical chiropractic care for 2 years. After four months of upper cervical chiropractic care, all Multiple Sclerosis (MS) symptoms were absent. A follow-up MRI showed no new lesions as well as a reduction in intensity of the original lesions. One year later, further MRI evaluation showed no new lesions and continued reduction in intensity of the original lesions. Two years after upper cervical chiropractic care began, all MS symptoms remained absent.9 These limited case reports suggest a relationship between cervical spine subluxations and neurological disorders. The present case reports on the successful management of a 45 year old male with a chronic history of Tourette¶s syndrome, tardive dyskinesia, and CREST syndrome; where CBP technique was used to reduce the cervical spine subluxations of the patient. Case Report: Patient presentation There have been instances when neurological disorders such as these have successfully improved under chiropractic care. For instance, Elster7 reported on a 9-year-old male who had Tourette¶s, attention deficit hyperactivity disorder (ADHD), depression, insomnia, and headaches. His medications included Albuterol, Depakote, Wellbutrin, and Adderall. After evaluation, there was evidence of upper cervical subluxation using thermography and radiographic diagnostics. Specific upper cervical adjustments were used to reduce the subluxation. The analysis and adjustments were given based on the international upper cervical chiropractic association protocol. After 6 weeks of care all six conditions were no longer present and all medications were discontinued with the exception of a half-dose of Wellbutrin. At the conclusion of his case at five months, all symptoms remained absent.7 A 45-year-old male technical specialist presented into a clinic where the Chiropractor¶s focus was Chiropractic BioPhysics Technique (CBP). At the time of initial presentation, he complained of fatigue and concurrent conditions of Tourette¶s syndrome, tardive dyskinesia, and CREST syndrome. A review of past and present medical conditions was significant where the patient indicated a history of irritable bowel syndrome, neck pain, irritability, shortness of breath, diarrhea, cold hands and feet, and carpal tunnel syndrome. The patient also stated that he had low cortisol levels due to adrenal insufficiency. In the 5th grade (approximately 10 years of age), the patient was diagnosed with legg-calve-perthes syndrome and was placed in a brace for his left hip. At this time he, was prescribed on growth hormone due to an abnormal pituitary duct causing diminished growth. Bastecki et al8 presented a case of a 5-year-old male diagnosed with ADHD that was treated by a pediatrician unsuccessfully with methylphenidate (Ritalin), Adderall, and Haldol for 3 years. The patient¶s primary cervical subluxation was a cervical kyphosis. The patient was treated using Chiropractic BioPhysics CBP technique where 35 treatments over 8 weeks using postural mirror image adjustments, exercises, and traction were administered. An improvement in cervical kyphosis to a 32 lordosis was observed after treatment. Over the course of care, the child's facial tics resolved and his behavior vastly improved. After 27 visits, the child's pediatrician stated that the child no longer exhibited symptoms of ADHD.8 Previous medications and interventions were described as numerous. Over the past ten years to date, he was prescribed ORAP for Tourette¶s syndrome, Haldol for tardive dyskinesia, he had been receiving electrophoresis in his upper trapezius region every 3 months, he had cortisone injections in the right wrist for carpal tunnel syndrome, which made his wrist swollen and numb afterwards. The patient had complaints of neck and upper back pain and was given Botox injections in his neck and upper traps. Over the past one and half months, the patient indicated he was extremely fatigued after using the treadmill, which was part of his reason for the visit to the office. Other medications he noted were Cardizem, Synthroid, Colchicine, Prevalid, Propulsid, Flonase, and Klonopin. In another case, a 47-year-old female experiencing multiple sclerosis (MS) symptoms for the previous 3 years was reported by Elster9 The patient was exhibiting multiple Upon visual observation, it was noted that the patient had an uncoordinated staggering gait as he walked, a significant stutter when he spoke, and he had resting tremors in both his arms and hands and they were semi-flexed on his chest. Biophysics J. Vertebral Subluxation Res. August 19, 2010 2 Postural Examination The postural examination showed multiple postural subluxations. The patient¶s head posture was: 1) left head axial rotation (+RyH), 2) right head to thorax translation (TxH), 3) left head lateral flexion (-RzH), and 4) anterior head translation (+TzH). The patient¶s thorax posture was: 1) right thorax to pelvis rotation (-RyT), 2) right thorax to pelvis lateral flexion (+RzT). The patient¶s pelvic posture was: 1) right pelvic to feet lateral flexion (+RzP). Figure 1 presents the patient¶s primary (largest) presenting subluxated postural positions. Radiographic Examination Antero-posterior (AP) cervical-thoracic x-ray showed 16 right lateral tilt of C5-T4 segments relative to vertical, a 20 left cervico-dorsal (mid-neck scoliosis) angle, a 22mm right lateral translation of C2 relative to T4. The lateral cervical radiograph showed a 20 cervical lordosis with a 20 atlas plane angle. All radiographic lines and measurements were based on CBP protocol and have been reported to be reliable in the literature.10,11 Figure 2 presents the initial AP cervical radiograph of the patient. Intervention and Outcomes The patient received CBP care over a one-year period. CBP technique can be best described as a full spine and posture rehabilitative technique where the primary goal of care is to restore normal alignment to the human spinal column and body posture. Subluxation is characterized as one or more structural displacements of the spine and posture as rotations and translations relative to a normal alignment position.12-15 Figure 3 defines the normal alignment position of the human spine and posture.12-15 The care began by having the patient come in for 3 times a week for the first 12 weeks per CBP protocol.12,13 The patient¶s posture was notably improved but still present, so the treating Chiropractor (A.C) reduced the frequency of visits to 2 times per week thereafter for an additional 9-months. The patient received approximately 108 treatments over the 1-year time period. Specific CBP mirror image (opposite postural position) adjustments, exercises, and traction were applied each visit to reduce the postural and cervical spine subluxations towards normal. The mirror image adjustment is a specific chiropractic adjustment that places the patient in their exact opposite or mirror image posture while applying a certain adjusting force.12,16 Some of these forces applied may be diversified, drop table or toggle maneuvers, as well as the use of an adjusting instrument.12,16 Mirror image drop-table adjustments were given each visit to reduce the primary postural displacements as shown in figure 4. In addition to the adjustments, the patient was sent home with mirror image exercises in which the patient held his head in the mirror image posture for 10 seconds and then relaxed it, repeating this 20 times. Figure 5A depicts the mirror image exercise. The patient was also given a left head to thorax mirror image traction in which he was asked to lie face down Biophysics with his head rotated to the right and held there for 1 min, 5 times throughout the day. Each of these exercises and traction were given to follow the CBP protocol.12,13 In addition to the adjustments, exercises, and traction the patient was given a 7mm heel lift for his right foot. The heel lift was given to him to balance his pelvis because he had a 7mm anatomical short leg length verified via radiography. The analysis used for this was the CBP line drawing protocol for anatomical leg length inequality.17 By the 2nd month of care the patient¶s wife reported that his tremors had lessened, his energy level was much higher, and his speech seemed to be improving. After one year of care, since his progress was going well and his posture was improving post x-rays were ascertained on the patient. Anteroposterior cervical radiographs showed improved subluxations: the C5-T4 lateral tilt angle to vertical was 5 to the right (an 11 improvement), the cervico-dorsal angle was now 8.5o to the left (11.5o improvement), and the lateral translation of C2 relative to a vertical line up through the center of T4 vertebra was 6mm to the right (16mm improvement). See figure 6. Discussion It is known in neurosciences that the central nervous system controls each and every function in the human body. According to Lennon et al18: ³Posture affects and moderates every physiological function from breathing to hormonal production. Spinal pain, headache, mood, and blood pressure, pulse, and lung capacity are among functions most easily influenced by posture´ With that being said, can abnormal posture and cervical spine subluxation interfere with nervous system function and in turn cause symptoms such as Tourettes, tardive dyskinesia, fatigue, or scleroderma? The answer to this question remains unknown. However, we speculate that resolution of the symptoms in the current case report may be credited to the correction of the patient¶s abnormal postural and spinal subluxations. In order to understand how posture and affects the body, we must begin by understanding what is normal posture. Harrison et al14,16 described posture displacements of the head, thorax, and pelvis as rotations and translations around and along the three Cartesian coordinate axes (x, y, z) in three dimensions (3-D) relative to an origin of neutral posture (Figure 3). Since all matter has the ability to rotate or translate in space, we can say that this also applies to the human body parts. Body parts have the ability to rotate and translate around and along each of the axes. Using a defined Cartesian coordinate system, rotation around the x-axis would be any type of flexion or extension, rotation around the y-axis would be right or left rotation, and rotation around the z-axis would be right or left flexion. Translation is a linear motion or any motion along a straight line. Thus, a translation along the xaxis would be any linear movement to the left or right, translation along the y-axis is any movement upward or downward, and translation along the z-axis would be any movement going forward or backward.14,16 Figure 7 shows the 6 rotations and 6 translations of the head relative to the thorax in 3-D. Every posture is explained by comparing the position of the J. Vertebral Subluxation Res. August 19, 2010 3 head in relation to the thorax, the position of the thorax in relation to the pelvis, and the position of the pelvis in relation to the feet. The head, thorax, and pelvis are the three global units described when looking at posture.14,16 According to the Harrison14,16, for ideal spine and postural alignment when viewed from the front, the center of the skull should be over the center of the thorax, and the center of the thorax should be over the center of the pelvis and the pelvis should be over a point in the middle of the feet (Figure 3). From the side view, the middle of your ear should be over the middle of the shoulder, the shoulder should be over the greater trochanter of the hip and the greater trochanter should over lateral maleolus of the ankle (Figure 3).14,16 There is a saying that says our ³posture is the window to our spine.´ With abnormal posture it is understood that there is abnormal structure of the spine. In fact, each rotation and translation of the head and ribcage have unique spinal kinematic responses known as coupled motion.13,14,16,17 Understanding the anatomy of the spinal cord and how it attaches to the spine (the dentate ligaments and other connective tissues anchor the spinal cord to the spine from C1 to L2) allows for an appreciation of how spinal subluxations alter the position of and forces acting on the spinal cord and nerve roots. When abnormal posture and spine displacement (subluxation) is present in a patient, there are concomitant increased and abnormal stresses and strains acting on the spinal cord due to ligamentous attachments anchoring the spinal cord to the spinal canal.19-21 When the spinal cord is subjected to abnormal increased stress (tension, compression, shear, and torsion loads) and strain (both longitudinal and cross-sectional) there may be an internal pressure increase and change in vascularization. Increased spinal cord pressures in the range caused by altered spinal position, has been shown to alter the pressure of perfusion of the cord and impair oxidative phosphorylation in the mitochondria of the neuron.19-21 Impaired function of the mitochondria brings about a decrease in cell biosynthesis which is, in our opinion, the essence of nerve interference.20,21 Again, because it is understood that the nervous system controls all functions in the body, nerve interference due to abnormal posture and spine alignment (subluxation) may very well cause a disturbance in physiology leading to neurologic symptoms. Certainly, the above discussion is speculative in nature but we see no other logical alternative explanation for the positive improvement in the current case report and those previously reported in the literature.7,9,10 Conclusion With a greater understanding of posture and how it affects the nervous system, we may appreciate that abnormal posture can cause abnormal function of the body. Tourette¶s syndrome, tardive dyskinesia, and fatigue are all abnormal functions of the body. When we see such a patient having a gross abnormality in their spine, it is possible that this abnormality could potentially be interfering with the proper function of the nervous system. Thus, abnormal function may have progressed into complex neurological symptoms such as Tourrettes, tardive dyskinesia, etc. The present patient case underwent long term chiropractic care and correction of their abnormal posture and spine structure (subluxation). Reduction of the spine subluxation may have reduced the stress and strain on the spinal cord leading to improved physiologic function; thereby relieving him of some of his symptoms. It is understood that there is a need for more research in this area. Since this is a case study there are limitations of what can be assumed. Clinical control trials with appropriate sample size are needed to verify or refute the positive results of chiropractic care on complex neurological disorders. However, as far as what can be said from this study, chiropractic care helped improve the life of this individual patient; in the end our duty is to individual who walks through our doors.

ORAP is an antipsychotic used to treat Tourette¶s and chronic schizophrenia. Problematically, long-term use of ORAP has been associated with increased risk of tardive dyskinesia and neuroleptic malignant syndrome (NMS); serious and potentially fatal conditions. Given the serious adverse events associated with the use of medications for the treatment of Tourettes and disorders as in the present case, chiropractic procedures aimed at restoring the normal posture and alignment of the spine may prove to offer a safer initial course of conservative care. 7. 8. 9.
