This study aimed to investigate the effect of double oscillation exercise combined with elastic band exercise on the strength and thickness ratio of the scapular stabilizing muscles in healthy young individuals. A total of 30 subjects (17 male, 13 female) were randomly assigned to an elastic band exercise group (EBG) (n = 15) or an elastic band plus double oscillation exercise group (EB-DOG) (n = 15). A total of 28 subjects completed the experiment and evaluation. Patients in the EBG performed the elastic band exercise for shoulder flexion, extension, abduction, adduction, horizontal abduction/adduction, and internal/external rotation for 30 minutes/session, five times/week, for four weeks. Patients in the EB-DOG performed the elastic band exercise for 15 minutes and the double oscillation exercise in three planes of motion (frontal, sagittal, and transverse), using a Bodyblade® for 15 minutes/session, five times/week, for four weeks. Shoulder muscle strength was assessed using a manual muscle test device during maximal voluntary isometric contraction (MVIC), while the thicknesses of the scapular stabilizing muscles were assessed using rehabilitative ultrasound imaging both at rest and during MVIC. Both groups had significant effects on shoulder muscle strength, however, there was no significant difference between the two groups for change value of shoulder muscle strength (Bonferroni correction p < 0.005). Significant differences were observed in the group × time interactions for horizontal abduction, external rotation, and protraction. There was a statistically significant improvement in thickness ratio of LT and SA in the EB-DOG and no significant difference was founded in EBG (Bonferroni correction p < 0.006). In comparison between the two groups, EB-DOG showed a significant change in the thickness ratio of LT compared to EBG. In addition, significant differences were observed for the group × time interactions for the thickness ratio of the LT (F = 12.177, P = 0.002; Bonferroni correction p < 0.006). The double oscillation exercise combined with elastic band exercise more effectively increased the thickness of the shoulder stabilizing muscles compared with the resistance exercise alone.
本研究旨在探讨双振荡运动联合弹力带运动对健康年轻个体肩胛稳定肌力量及厚度比的影响。共有30名受试者（17名男性，13名女性）被随机分为弹力带运动组（EBG）（n = 15）或弹力带加双振荡运动组（EB - DOG）（n = 15）。共有28名受试者完成了实验和评估。EBG组患者进行弹力带运动，包括肩部前屈、后伸、外展、内收、水平外展/内收以及内/外旋，每次30分钟，每周5次，共进行4周。EB - DOG组患者进行15分钟的弹力带运动，并使用Bodyblade®在三个运动平面（额状面、矢状面和横断面）进行15分钟的双振荡运动，每次运动15分钟/session，每周5次，共进行4周。在最大自主等长收缩（MVIC）期间，使用手动肌力测试装置评估肩部肌肉力量，同时在静息状态和MVIC期间使用康复超声成像评估肩胛稳定肌的厚度。两组对肩部肌肉力量均有显著影响，然而，两组之间肩部肌肉力量的变化值无显著差异（Bonferroni校正p < 0.005）。在水平外展、外旋和前伸的组×时间交互作用中观察到显著差异。EB - DOG组中LT和SA的厚度比有统计学显著改善，而EBG组未发现显著差异（Bonferroni校正p < 0.006）。两组比较，EB - DOG组与EBG组相比，LT的厚度比有显著变化。此外，LT厚度比的组×时间交互作用也观察到显著差异（F = 12.177，P = 0.002；Bonferroni校正p < 0.006）。与单独的阻力运动相比，双振荡运动联合弹力带运动更有效地增加了肩部稳定肌的厚度。
