Purpose : To investigate the immediate effects of transcutaneous electrical nerve stimulation(TENS) on the spasticity and the balance in the stroke patients. Methods : 26 subjects with spasticity over lower limbs were allocated randomly into two groups : (1) TENS group, (2) placebo-TENS group. TENS was applied on the both gastrocnemius for 60 minutes(100 Hz, 0.25 ms, 2 times sensory threshold). The modified Ashworth Scale(MAS) and Manual Muscle Tester were used to assess the spasticity of the ankle plantar flexors. Static balance under three conditions was measured by force-plate; in (1) the condition of standing with eyes opened, (2) with eyes closed and (3) the condition of standing on unstable surface with eyes opened. Results : When compared with the pre and post TENS application, TENS showed significant reduction of ankle spasticity in MAS and MMT measurement. Also, Application of high-frequency TENS improved the balance under three conditions. Conclusion : A single session of TENS to stroke patients could reduce spasticity and improve the balance.

PURPOSE: The purpose of this study was to determine if an exercise program with vertical vibration can improve balance, walking speed, muscle strength and falls efficacy in the healthy elderly. METHODS: A total of 28 elderly were randomly divided into two groups: vertical vibration exercise group (exercise with vertical vibration) (N = 14) and control group (exercise without vibration) (N = 14). The exercise program, comprising calf raise, deep-squat, semi-squat, front lunge, and leg abduction was conducted with or without vibration, respectively. Subjects in each group participated in the 30 minutes training program, 2 times per week for 6 weeks. In both groups, the balance evaluation system (BT4) was used to evaluate standing balance, and walking speed was measured using the 10MWT. The manual muscle test system was applied to evaluate the knee extensor and ankle planter flexor muscle strength of the subjects, whereas the Korean falls efficacy scale (K-FES) evaluated the falls efficacy. RESULTS: After intervention, the vertical vibration group showed significantly higher changes compared to the control group, in the parameters of standing balance (P < .05), 10MWT (P < .05), left knee extensor (P < .05), right knee extensor (P < .01), both ankle plantar flexors (P < .05), and K-FES (P < .05). CONCLUSION: The exercise program with vertical vibration has the potential to improve balance, walking speed, muscle power and falls efficacy in the elderly.

본 연구는 만성 뇌졸중 환자를 대상으로 2주간 후각 자극이 균형, 경직 및 삶의 질에 미치는 효과를 규명하기 위하여 실시되었다. 단일맹검 및 사전 무작위 임상시험으로 진행되었으며, 21명의 만성 뇌줄중 환자는 무작위로 후각자극군(n=10)과 속임 후각자극군(n=11)으로 배정되었다. 후각자극 군은 라벤더 오일을 2주간 주 5회, 총 10회 시행하였고, 속임 후각자극 군은 물을 적용하였다. 경직은 Composite Spasticity Score (CSS)를 사용하여 측정하였고, 정적 균형은 힘판(force plate), 동적균형은 Timed up and go test(TUG), 삶의 질은 Short-Form 36 items(SF-36)를 사용하였다. 훈련 후 후각자극 군이 속임 후각자극 군에 비해 정적균형이 유의하게 개선되었으며(p<.05), 경직과 동적균형은 집단 간 유의한 차이가 없었다. 또한, 후각자극 군에서 SF 36의 정신적 건강요약과 총점이 속임 후각자극 군에 비해 유의하게 개선되었다. 본 연구는 후각자극이 만성 뇌졸중 환자의 정적균형과 삶의 질을 효과적으로 향상시킴을 증명하였다.
