UNLABELLED
The aim of this study was to determine if chronic shoulder pain had an effect on arm abduction strength and recruitment strategies of the serratus anterior, middle deltoid, and upper trapezius.
METHOD
The maximal isometric force at 30° arm abduction and the electromyographic activity of the serratus anterior, middle deltoid, and upper trapezius were recorded for 14 subjects with unilateral chronic shoulder pain and 11 healthy subjects.
RESULTS
Relative to the group without pain, the group with chronic shoulder pain showed no significant difference in maximal force production during isometric arm abduction. The Mann-Whitney tests showed no differences in the activation of the serratus anterior, middle deltoid, and upper trapezius between the two groups.
DISCUSSION AND CONCLUSION
Subjects with chronic shoulder pain of mild to moderate intensity showed no difference from healthy subjects in arm abduction maximal strength, and recruitment patterns of serratus anterior, middle deltoid, and upper trapezius.
未标注
本研究的目的是确定慢性肩部疼痛是否会影响手臂外展力量以及前锯肌、三角肌中束和斜方肌上束的募集策略。
方法
记录了14名单侧慢性肩部疼痛患者和11名健康受试者在手臂外展30°时的最大等长力量以及前锯肌、三角肌中束和斜方肌上束的肌电活动。
结果
与无疼痛组相比，慢性肩部疼痛组在等长手臂外展过程中的最大力量产生方面无显著差异。曼-惠特尼检验显示两组在前锯肌、三角肌中束和斜方肌上束的激活方面无差异。
讨论与结论
轻度至中度慢性肩部疼痛的受试者在手臂外展最大力量以及前锯肌、三角肌中束和斜方肌上束的募集模式方面与健康受试者无差异。
