中文摘要 | 本篇研究的主要目的在利用肌力評估系統配合肌電圖分析,探討不同頭 頸位置對雙上臂彎曲舉物肌力值的影響,以及調查性別、體重、身高、上臂長和 周徑與雙上臂彎曲舉物肌力值的關係。41位大學生(男27位、女14位)利用一套力 量評估測試系統,在頭頸伸張、彎曲和正中三個不同位置下各做二次靜態雙上臂 彎曲舉物肌力測試。 結果顯示:無論男女,最大的肌力值出現在頭頸伸張位置時,其次為正中位置, 當頭頸在彎曲位置舉物的力量最小;伸張時的肌力值和彎曲位置舉物肌力值的差 異在統計學上有明顯的意義;男性在三種不同位置的肌力值都明顯地出女性大。 雖然統計學上顯示尖峰肌力值和肌電圖尖峰電位值之間有明顯相關性,但是在不 同頭頸位置的肌電圖電位值,在統計學上並沒有明顯的差異性。此外,利用多重 迴歸分析發現,在三種不同的位置下:體重、身高、上臂長和周徑等人體參數測 量值和舉物肌力值都沒有明顯相關性,只有性別因素,在統計學上和舉物肌力值 有明顯重要的相關性。(中華物療誌1996;21(2):83-93) |
英文摘要 | The purpose of this study was to examine whether the muscle strength of the elbow flexorswould be influenced by head and neck (UN) positions. Forty-one healthy male and female students between the ages of 19 and 32 years volunteered as subjects. A Force Evaluation andTesting System (FET 5000) was used to measure the arm lifting strength in the standing positionswhile each subject keeping his head in various prescribed positions (neutral, flexion, and extension). The mean force of two trials was determined for each HN position. At the same time,etectromyographic activity of bilateral biceps brachii muscles was quantified during maximal voluntary isometric arm lifting. Repeated measures analysis of variance was used to analyze theeffects of HN positions on the amount of elbow flexors force and integrated electromyographic(IEMG) values. The results showed that the highest mean lifting strength was recorded at extension position for both males and females. Significant differences were found between HN positionsand arm lifting strength. In the other way, no significant difference of the IEMG values of bilateral biceps brachii muscles between HN positions were found. However, this study seemed to support the conclusion that HN position did influence on the production of isometric elbow flexorsforce. The actual clinical implication is limited due to the limitations of the study. (JPTA ROC1996;21(2):83-93) |
