기능적 전기자극 적용이 근육 및 보행 기능에 미치는 영향

초록

Objective: The purpose of this research was to analyze the effects of applying functional electrical stimulation (FES) on function of the ankle joint and gait ability of the elderly. Method: In this research, 12 male participants over 65 who have no musculoskeletal disorder were recruited as research subjects. For this research, in order to analyze the function of the ankle joint and gait ability of the elderly depending on the application of FES, all subjects were tested WF (with FES) and WOF (without FES) in random order and 72-hour of resting was assigned between the conditions. For WF condition, 30-minute of FES treatment (frequency 90 Hz, pulse width 400 μs, on-off ratio 1:1) on ankle joint basal flexor muscle was implemented, and afterwards, Isokinetic muscle function on the ankle joint and gait ability were conducted for each condition. Results: The result showed that the maximum strength of ankle joint basal flexion motion WF statistically significantly increased compared to WOF. The single support ratio of gait motion WF statistically significantly decreased compared to that WOF. Conclusion: Thus, applying FES is considered to mitigate the functional decline of basal flexor of the elderly, and furthermore, it is considered to have positive effect on improvement of gait ability.
