A manual shoulder-training device may represent an alternative training device to improve symptoms and function in patients with subacromial shoulder pain by strengthening the external rotators. Thus, we examined the effects of a traditional versus an alternative strengthening exercise program on shoulder pain/function and physical performance in individuals with subacromial shoulder pain. Fifty-six adults with subacromial shoulder pain were randomly assigned to a passive control group (CON; = 20), a traditional training group (TRA; = 19), or an alternative training group (ALT; = 17). Both training groups conducted a progressive home-based strengthening exercise program for the external rotators for eight weeks using elastic bands only (TRA group) or in combination with the shoulder-training device (Schulterhilfe®) (ALT group). Pre- and post-training assessment included measures of shoulder pain/function (i.e., shoulder pain and disability index (SPADI)) and physical performance (i.e., shoulder flexibility, maximal isometric strength, and strength endurance). We found significant test × group interactions in most of the investigated variables. Post hoc analyses showed significant training-related improvements for proxies of shoulder pain/function, shoulder flexibility, maximal isometric strength, and strength endurance in favor of the ALT and TRA group in comparison to the CON group. Further, larger and more frequent effects were found for the ALT compared to the TRA group. Measures of shoulder pain/function and physical performance can be significantly improved by both training regimens in individuals with subacromial shoulder pain. However, strength training using elastic bands with the manual shoulder device (ALT group) as compared to elastic bands (TRA group) only was more effective and may thus be a recommendable alternative in order to mitigate subacromial shoulder pain.
手动肩部训练设备可能是一种替代训练设备，通过加强外旋肌来改善肩峰下肩部疼痛患者的症状和功能。因此，我们研究了传统与替代强化训练方案对肩峰下肩部疼痛个体的肩部疼痛/功能及身体表现的影响。56名患有肩峰下肩部疼痛的成年人被随机分配到被动对照组（CON；n = 20）、传统训练组（TRA；n = 19）或替代训练组（ALT；n = 17）。两个训练组均进行了为期八周的渐进式家庭外旋肌强化训练方案，传统训练组仅使用弹力带，替代训练组则将弹力带与肩部训练设备（Schulterhilfe®）结合使用。训练前后的评估包括肩部疼痛/功能指标（即肩部疼痛和功能障碍指数（SPADI））和身体表现指标（即肩部灵活性、最大等长肌力和力量耐力）。我们发现在大多数研究变量中存在显著的测试×组交互作用。事后分析表明，与CON组相比，ALT组和TRA组在肩部疼痛/功能指标、肩部灵活性、最大等长肌力和力量耐力方面有显著的训练相关改善。此外，与TRA组相比，ALT组的效果更大且更频繁。两种训练方案均可显著改善肩峰下肩部疼痛个体的肩部疼痛/功能和身体表现。然而，与仅使用弹力带（TRA组）相比，使用弹力带结合手动肩部设备进行力量训练（ALT组）更有效，因此可能是缓解肩峰下肩部疼痛的推荐替代方案。
