Conventional therapeutic exercise programs are commonly used to treat patients with scapular dyskinesis. There are no studies that have examined traditional therapeutic exercise programs with the addition of remote triggered electrical stimulation (ES) to affect the position of the scapula (using spine to scapular border distance as a reference point) during the performance of exercises that have lower upper trapezius (UT) to lower trapezius (LT) ratio exercises.
The purpose of this pilot study was to compare scapular position after performance of three low UT/LT ratio therapeutic exercises in two conditions, electrical stimulation (ESTherex) and sham electrical stimulation (ShamTherex) in asymptomatic persons who were positive for scapular dyskinesis.
Randomized trial, single-blinded.
Eleven asymptomatic university students representing 15 scapulae with a positive Scapular Dyskinesis Test were recruited as subjects. Participants were randomized into exercise and electrical stimulation (ESTherex) or exercise and sham electrical stimulation (ShamTherex). Subjects performed side-lying shoulder external rotation and flexion, and prone horizontal abduction with external rotation in both conditions. Scapular position was assessed during active abduction at four angles before and after performance of these exercises.
There were no significant differences in scapula to spine distance between ESTherex and ShamTherex groups at 0, 45, 90 and 120 degrees of shoulder abduction. A between group difference (ESTherex and ShamTherex) approached significance at 45 degrees (p = 0.089, CI=-.152 to 1.88 cm) with the post mean measurement of the ShamTherex group (6.44 cm) greater than the post mean measurement of the ESTherex group (5.57 cm). The ESTherex showed a significant pre-to-post mean within group improvement in spine to scapula distance at 120 degrees (mean 2.76 cm, t=4.89, p=.003).

传统治疗性运动方案常用于治疗肩胛运动障碍患者。尚无研究探讨在传统治疗性运动方案基础上增加远程触发电刺激（ES），对肩胛运动障碍阳性的无症状者在进行上斜方肌（UT）与下斜方肌（LT）比例较低的运动时肩胛位置（以脊柱至肩胛边缘距离为参考点）的影响。
本初步研究的目的是比较肩胛运动障碍阳性的无症状者在电刺激（ESTherex）和假电刺激（ShamTherex）两种情况下，进行三种低UT/LT比例治疗性运动后肩胛的位置。
随机单盲试验。
招募了11名无症状大学生，代表15侧肩胛运动障碍试验阳性的肩胛作为研究对象。参与者被随机分为运动加电刺激组（ESTherex）或运动加假电刺激组（ShamTherex）。在两种情况下，受试者均进行侧卧位肩外旋和屈曲以及俯卧位水平外展加外旋。在进行这些运动前后，于四个角度的主动外展过程中评估肩胛位置。
在肩外展0°、45°、90°和120°时，ESTherex组和ShamTherex组的肩胛至脊柱距离无显著差异。在45°时，组间差异（ESTherex和ShamTherex）接近显著水平（p = 0.089，CI = -0.152至1.88厘米），ShamTherex组的测量后均值（6.44厘米）大于ESTherex组的测量后均值（5.57厘米）。ESTherex组在120°时脊柱至肩胛距离的组内测量前均值至测量后均值有显著改善（均值2.76厘米，t = 4.89，p = 0.003）。
