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. [Left/Right] [Front/Back] [Up/Down] [Horizontal plane trace length] [Frontal plane trace length] ●Red：dorsal vertebrae region ●Blue：sacral region Data samples Walk Straight mally while the data da ta is measur ed . The walks normally measured. T he subject subjec t w alks nor Recommended R ec ommended ： 10m or more, mor e , walking w alk ing in a straight str aigh t line 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.
