Blood flow restriction training (BFRT) appears to promote the strengthening of shoulder muscles, but primary clinical applications are limited to the lower extremity.
Two female recreational athletes (Case A: 27 years old; Case B: 28 years old) with subacromial pain were treated with BFRT (50% occlusion) during 3 isotonic strengthening exercises of the upper extremity against 20% of the maximal isometric strength. At the beginning of each treatment week, we measured strength with a handheld dynamometer to ensure appropriate load progression.
OUTCOME AND FOLLOW-UP: Case A completed 16 visits and Case B completed 22 visits of BFRT with no adverse events. At discharge, we found meaningful improvement for patient-reported function, clinical measures of shoulder flexion and external-rotation range of motion and isometric strength, supraspinatus and infraspinatus cross-sectional area, and upper extremity performance.
BFRT may be a valuable adjunct to standard rehabilitation for the conservative management of subacromial pain. Despite the inherent limitations of our design, we believe these preliminary findings are compelling to warrant future investigations.
血流限制训练（BFRT）似乎有助于增强肩部肌肉力量，但主要临床应用仅限于下肢。
两名患有肩峰下疼痛的女性休闲运动员（病例A：27岁；病例B：28岁）在进行上肢等张强化训练时接受了BFRT（50%闭塞），训练强度为最大等长肌力的20%。在每个治疗周开始时，我们使用手持测力计测量力量，以确保适当的负荷进展。
病例A完成了16次BFRT治疗，病例B完成了22次BFRT治疗，均未出现不良事件。出院时，我们发现患者报告的功能、肩部前屈和外旋活动范围及等长肌力的临床测量、冈上肌和冈下肌横截面积以及上肢表现均有显著改善。
BFRT可能是肩峰下疼痛保守治疗标准康复方案的一种有价值的辅助手段。尽管我们的设计存在固有局限性，但我们认为这些初步发现很有说服力，值得未来进一步研究。
