Outline of Final Research Achievements

We conducted the crossover study of BEAR and conventional balance exercise for 23 patients with balance disorder. Confortable gait speed, Timed up and go test, Functional reach test, muscle strength of gluteus medius and triceps surae improved after BEAR exercise intervention period. For one of the patient, we evaluated the balance strategy using Equi test, and involvement of ankle strategy increased.
In another research, subjects, comprising seven healthy adults, played 3 types of games. The games had four levels of difficulty and each game was played for 90 seconds. Surface electromyography was used to measure 16 muscles of bilateral lower extremities. Mean muscle activity was calculated from muscle integrated electromyography. Muscle activity in each game increased with the degree of difficulty.
3D motion analysis and surface electromyography was evaluated simultaneously for one healthy subject and one hemiplegic patient. The range of motion of knee angle was larger in the subject.
