New Motion Capture to the next generation
THE WALKING
2-point gait oscillometer M VP - WS2 - S
MVP-WS2-S
A visual representation of the movement of the body when walking!
2-point gait oscillometer
MVP-WS2-S
① Uses 2 motion sensors to measure the motion traces in the area of the dorsal
vertebrae and the sacral region while walking.
Explanation of main features/display screen
Fields of Application
Physiotherapy
Sports
Walking Gear
②The use of compact, wireless sensors allows measurement to take place anywhere.
Attaching the sensors is also easy!
③Allows the display of an animated image synchronizing the motion of the 2 points!
The relationship between the two points is clear at a glance, making the motion easy to visualize!
Step1 Fitting the sensors
Measuring device
MVP-RF8 series
Trace display
(Lissajous figure)
Displays the multiplestep cycle average
motion trace at the
point at which the
sensor is attached.
●Red：
dorsal vertebrae region
●Blue：
sacral region
Step timing display
The sensors are
attached to①the area of the dorsal vertebrae
②the sacral region
using the special
belt and harness
●The green line links
the same-time positions
of the dorsal vertebrae
and the sacrum.
8-channel compact wireless
motion recorder
Step2 Measuring the data
Wireless data
communication
Up to approx. 30m
Walking phase display
Animated display
Motion magnitude display
Schematic display of the walking phase
during one cycle including the timing at
which the right and left feet hit the ground.
Displayed animated playback
of movement
(about step phase and timing)
The magnitude of the motion in each
direction in one cycle is calculated and displayed.

Step3 Data analysis, display of results
Once the measurement is completed,
the data is automatically analyzed
and the results displayed.
The data can be saved in .csv format.
Gait with good overall balance
Gait making little use of the muscular strength of
the legs/area around the center of gravity
Gait of a person with back pain
The dorsal vertebrae/sacrum have similar motion traces. The body moves to
the right and left as the foot hits the
ground, spreading the impact.
There is pronounced left-right motion in the upper part
of the body.The movement of the arms compensates
for the lack of muscular strength in the legs/area
around the center of gravity and provides motive force.
There is little left/right motion at the dorsal vertebrae/sacrum.
There is a strong up-down impact when
the foot hits the ground.
