Activation of Transverse Abdominis and Deep Multifidus in Healthy Subjects during Different Tasks for Trunk Stabilization
正常人腹橫肌及深層腰椎多裂肌在不同軀幹穩定任務下的收縮模式
摘要
Background and purpose: The activation of deep core muscles during different trunk stabilization tasks is not clear. The objective of the study is to compare the activation pattern of TrA and dMF during performing different tasks of trunk stabilization. Methods: Twenty one participants performed five tasks: an abdominal draw-in maneuver (ADIM), a prone hip extension with or without draw-in for the ipsilateral leg (DI, I), and the contralateral leg (DC, C). Change of thickness (∆T) and sliding (∆X) of the TrA and ∆T of the dMF were measured by ultrasonography. Two-way and one-way repeated analysis of variance (ANOVA) was used for data analysis. ∆T of the TrA and the dMF were tested by the Pearson correlation. Results: TrA thickness during ADIM was greater when comparing to C and I (p ＜ 0.005). ∆T of the TrA during ADIM was greater than those of I and C (p ＜ 0.005); DC was greater than I (p ＜ 0.005); and DI was greater than C and I (p ＜ 0.005). ∆X during ADIM were greater than DC, DI, C and I (p ＜ 0.005). ∆T of the dMF during DI, DC, I and C were greater than ADIM (p ＜ 0.005). Correlation between ∆T of the TrA and the dMF during C was found (r = 0.55, p ＜ 0.05). Conclusion: The draw-in maneuver was favorable for activation of the TrA; the dMF has greater contraction during lifting the lower extremities. The co-contraction of the TrA and the dMF was identified during lifting of the contralateral lower extremity.

背景與目的：深層核心肌群在不同軀幹穩定任務下的收縮模式並不清楚。本篇研究的目的在於比較腹橫肌及深層腰椎多裂肌在不同軀幹穩定任務下的收縮模式。方法：21位受試者進行5種不同的動作：腹部收縮(ADIM)、趴姿下同側腳髖關節伸展並伴隨或無伴隨腹部收縮(DI, I)、趴姿下對側腳髖關節伸展並伴隨或無伴隨腹部收縮(DC, C)。使用超音波量測腹橫肌的肌肉厚度及滑動程度改變量以及深層腰椎多裂肌肌肉厚度的改變量，雙因子及單因子重複測量變異數分析資料。使用皮爾森相關係數分析腹橫肌和深層腰椎多裂肌的肌肉厚度改變量。結果：腹橫肌的厚度在腹部收縮動作時較C和I動作時大(p ＜ 0.005)，腹橫肌的肌肉厚度改變量在腹部收縮動作時較C和I動作時大(p ＜ 0.005)；DC動作時腹橫肌的肌肉厚度改變量較I動作時大(p ＜ 0.005)；DI動作時腹橫肌的肌肉厚度改變量較C及I動作時大(p ＜ 0.005)；腹橫肌肌肉滑動程度改變量在腹部收縮動作時較DC、DI、C和I動作時大(p ＜ 0.005)；深層腰椎多裂肌的肌肉厚度改變量在DC、DI、C和I動作時較ADIM動作時大(p ＜ 0.005)。腹橫肌和深層腰椎多裂肌的肌肉厚度改變量在C動作時相關(r = 0.55, p ＜ 0.05)。結論：腹部收縮較能有效誘發腹橫肌收縮；下肢抬腿動作較能有效誘發深層腰椎多裂肌收縮。對側腳抬高的動作較能有效誘發腹橫肌和深層腰椎多裂肌的協同收縮。
