New Idea of Walking Practice Using a Counter-Weight Suspension to Prevent Bedridden Condition
【Supercategory：7. DESCENTE SPORTS SCIENCE Subcategory：7.13 Vol.13】
We desighed the new apparatus for the walking practice, which relieves the load in a low limb by lightening a body weight, and examined usefulness of this device. Subjects were two male hemiplegic patients due to cerebrovascular accident. They were suspended with the counter-weight to 5% of body weight, and walked on the treadmill with the speed of 1.0 to 2.6 km / h and the inclination of 0 to 16%.
The results of walking during the body suspension were as follows :
1) Ventilatory Threshold (VT) and the oxygen uptake at the heart rate of 100 beats / min (Vo₂ 100) were almost same as the results of mesurement without suspension.
2) The angle of coxa at streached position increased, and resulted in the increase in the stride.
3) The duration of dorsi-flexion at the heel contact was prolonged.
4) The difference of the duration of swing phase and support phase in a walking cycle between disabled and abled side was not improved.
We observed that the body suspension technique was useful to measure cardio-respiratory fitness level accurately and safely in the hemiplegic patient, and that the pattern of gait was improved by using this technique. Therefor, counter-weight suspension technique seems to be useful for a hemiplegic patient to rehabilitate walking ability.
