中文摘要 | 本研究之主要目的在增進對自坐到站動作啟始期間下肢肌肉徵召時間 之了解,並探討起立速度及坐椅高度對肌肉受徵召時間的影響。共有六名健康成 年受試者參與此實驗,進行三種自坐到站的動作。在進行自坐到站的動作中,在 臀部離開坐椅之前,腓腸肌、脛前肌、股二頭肌、股直肌及臀大肌即開始收縮, 其中以股直肌與脛前肌常為最早被徵召的肌肉。當受試者以自然速度及最快速度 自正常高度椅子站立起來,肌肉受徵召時間並不因起立速度改變而有顯著不同; 而座椅高度升高也不會對肌肉受徵召時間產生顯著的影響。根據實驗結果認為下 肢之伸直肌及彎屈肌均參與自坐到站動作的啟始,文中亦對臨床治療提出建議。 (中華物療誌1993;18(1):41-48) |
英文摘要 | The purposes of this study were to investigate the effects of the speeds of risingand of the chair height on the onset timing of the leg muscle electromyography (EMG)activities during the initiation of rising from a chair to stand. Six healthy adults wererecruited and performed sit-to-stand movements under three task conditions. The tibialis anterior, gastrocnemius, biceps femoris, reef us femoris and gluteus maximus wereall activated prior to the onset of the lift-off of the buttocks from the chair. The TAand RF were usually the first to be recruited. The differences in the individual muscleonset timing between rising from normal chair at the speeds and at fast speeds werenonsignificant. The effects of increases in chair height on the onset timing of each ofthe five muscles were also nonsignificant. It is concluded that both flexor and extensor muscles in the leg participated in the initiation of rising up from a chair to stand.Suggestions for clinical training of sit-to-stand movement was also proposed.
