Abstract

Background: Sufficient shoulder flexor strength is necessary for accurate movement of the shoulder joint because several factors can cause compensatory movements of the scapula.

Objective: We investigated the influence of external fixation on the isometric shoulder flexors strength (ISFS) in individuals with and without scapular elevation (SE) during shoulder flexion.

Methods: The healthy and SE groups included 29 individuals. The ISFS was measured using a tensiometer (kg) under conditions of with and without external fixation, in a random order. The change in the ISFS (the strength difference with and without external fixation) was compared between the healthy and SE groups using an independent t-test.

Results: The change in the ISFS differed significantly between the healthy and SE groups (3.5% and 32.3%, respectively; p= 0.001).

Conclusion: These findings suggest that external fixation should be considered during shoulder flexion to determine the ISFS accurately in individuals with compensated SE.

外固定对肩胛骨抬高者肩部屈肌异构力量的影响。

背景：充足的肩关节屈肌力量是肩关节准确运动的必要条件，因为有多种因素会导致肩胛骨的代偿运动：我们研究了外固定对肩关节屈曲时有肩胛骨抬高（SE）和没有肩胛骨抬高（SE）的人等长肩关节屈肌力量（ISFS）的影响：健康组和 SE 组共 29 人。在有外固定和无外固定的条件下，使用张力计（kg）以随机顺序测量等长肩屈肌力量。用独立 t 检验比较健康组和 SE 组 ISFS 的变化（有外部固定和无外部固定时的力量差异）：结果：ISFS的变化在健康组和SE组之间存在显著差异（分别为3.5%和32.3%；P= 0.001）：这些研究结果表明，肩关节屈曲时应考虑外固定，以准确测定代偿性 SE 患者的 ISFS。

期刊介绍： The Journal of Back and Musculoskeletal Rehabilitation is a journal whose main focus is to present relevant information about the interdisciplinary approach to musculoskeletal rehabilitation for clinicians who treat patients with back and musculoskeletal pain complaints. It will provide readers with both 1) a general fund of knowledge on the assessment and management of specific problems and 2) new information considered to be state-of-the-art in the field. The intended audience is multidisciplinary as well as multi-specialty. In each issue clinicians can find information which they can use in their patient setting the very next day.
