Immediate Effect of Myofascial Release Along with Muscle Energy Technique on Range of Motion and Pain in Patients with Shoulder Impingement Syndrome - An Experimental Study

Aim: The aim of our study was to investigate the effectiveness of a single session of Myofascial release technique (MFR) along with Muscle Energy Technique (MET) on Range of Motion (ROM) and pain in patients with shoulder impingement syndrome. Background: “Shoulder Impingement Syndrome (SIS) is a generic term for injuries to structures in the sub-acromial space, often attributed to anatomical abnormalities involving the coracoacromial arch or humeral head. The term ‘impingement syndrome’ describes a cluster of signs and symptoms, typically including pain during overhead reaching, discomfort in the midrange of arm elevation, and positive provocation tests. Impingement is classified into two groups: intrinsic and extrinsic, with extrinsic further classified as primary, secondary, and internal.” Methodology: An experimental study was conducted which included 30 subjects with shoulder impingement. The subjects were divided into experimental who received MFR along with muscle energy technique &control group who received conventional physiotherapy using lottery method. The pre-post evaluation of pain using VAS, Range of motion was conducted. After that statistical analysis was conducted for intra & inter group comparison using paired & unpaired test respectively Results: The results indicated that myofascial release technique along with the muscle energy technique was more effective in improving range of motion in experimental group as compared to control group (P < 0.05). Conclusion: This study concluded that a single session of myofascial release technique along with muscle energy technique showed immediate improvement in the glenohumeral abduction and external rotation ROM.

研究目的：本研究旨在探讨单次肌筋膜释放技术（Myofascial Release Technique, MFR）联合肌肉能量技术（Muscle Energy Technique, MET）对肩峰下撞击综合征患者关节活动度（Range of Motion, ROM）与疼痛的改善效果。
研究背景：肩峰下撞击综合征（Shoulder Impingement Syndrome, SIS）是肩峰下间隙结构损伤的通用术语，常归因于喙肩弓或肱骨头相关的解剖异常。“撞击综合征”这一术语描述了一组体征与症状，通常包括上肢上举时疼痛、手臂抬高至中段范围时的不适感，以及激发试验阳性。撞击综合征可分为内在型与外在型两类，其中外在型又可进一步分为原发性、继发性与内源性三类。
研究方法：本研究为实验性研究，纳入30例肩峰下撞击综合征患者。通过抽签法将受试者分为两组：实验组接受肌筋膜释放技术联合肌肉能量技术治疗，对照组接受常规物理治疗。分别采用视觉模拟评分法（Visual Analogue Scale, VAS）评估疼痛程度、测量关节活动度完成治疗前后评估。随后分别采用配对t检验与独立样本t检验进行组内与组间比较的统计学分析。
研究结果：结果显示，相较于对照组，实验组采用的肌筋膜释放技术联合肌肉能量技术在改善关节活动度方面效果更显著（P < 0.05）。
研究结论：本研究表明，单次肌筋膜释放技术联合肌肉能量技术治疗可即刻改善盂肱关节外展与外旋活动度。
