摘要

背景與目的：迄今，已經有一些文獻報告描述軀幹肌肉表現的評估方法，而本研究的主要目的是探討軀幹肌力和肌耐力之間的相關性，不同姿勢所測得軀幹肌力之間的相關程度以及軀幹肌肉表現測量方法的重複測試信度。方法：本研究評估了50位健康成年人之腹肌和背肌的肌力和肌耐力，所採用的軀幹肌肉表現評估方法包括：使用手握式肌肉力量測試儀來量測腹肌（仰臥和坐姿）和背肌（俯臥和坐姿）的等長肌力以及使用等長肌肉收縮測試法來量測腹肌和背肌之肌耐力。以皮爾森雙尾相關性統計分析法來檢測各項軀幹肌力和肌耐力評估測試方法之間的相關性，並使用級內相關係數的信度分析法來評估各項測試之重複測試信度。結果：研究結果顯示軀幹肌力和肌耐力之間為低度相關，然而於不同姿勢下所分別測得之軀幹肌力具有高度相關，而且六項軀幹肌肉表現的測量方法皆具有相當高的重複測試信度。結論：在評估肌肉表現時，需分別做肌力及肌耐力之評估，至於軀幹肌力的評估則可選擇在躺著時或坐著時來評估，此外，本研究所使用的六種測量方法皆是高信度的軀幹肌肉表現評估方法。

Background and purpose: Up to date, researchers have described several simple techniques for testing trunk muscle performance. The purposes of the present study were to examine the correlation between trunk muscle strength and endurance, to determine the correlation of trunk muscle strength tested in different positions, and to examine the test- retest reliability of six tests of trunk muscle performance. Methods: Strength and endurance of the abdominal muscles and trunk extensor muscles were evaluated in 50 healthy adults. The tests included hand-held dynamometry of isometric flexion (supine and sitting) and extension (prone and sitting), and abdominal and extensor isometric endurance. Pearson correlation coefficients and intraclass correlation coefficients were calculated. Results: Low correlations were obtained between trunk muscle strength and endurance. However, there was a high correlation between trunk muscle strength measured in lying and that measured in sitting. All of the six tests had high test-retest reliability. Conclusions: Trunk muscle performance testing should include tests of both strength and endurance. Trunk muscle strength could be measured in lying or in sitting. Additionally, the six tests used in this study appear to be reliable in measuring trunk muscle performance.
