Neck is one of the most common sites of musculoskeletal symptoms, and muscle shortening and weakness is observed to be a common cause of neck pain and disability.
To compare the immediate and short term effects of static stretching (SS), autogenic inhibition (AI) and reciprocal inhibition (RI) muscle energy techniques (MET) on isometric muscle strength in the management of mechanical neck pain.
A randomized controlled trial was conducted on 78 participants with neck pain randomly allocated to SS, AI-MET and RI-MET groups. All the participants received Trans Cutaneous Electrical Nerve Stimulation (TENS), hot pack and unilateral postero-anterior glide, followed by 3-5 repetitions of either SS, AI-MET or RI-MET for five consecutive sessions. Numeric pain rating scale (NPRS) and Modified Sphygmomanometer Dynamometry (MSD) were used as outcome measurement tools. One way ANOVA and repeated measures ANOVA were used for inter-group and intra-group comparison.
In terms of MSD scores, a significant difference (p< 0.05) was observed between the groups. Both AI-MET and RI-MET were found to be comparatively more effective than SS, however AI-MET was found to be the most effective.
AI-MET is more effective than SS and RI-MET in terms of improving isometric muscle strength in patients with mechanical neck pain.
颈部是肌肉骨骼症状最常见的部位之一，肌肉缩短和无力被认为是颈部疼痛和残疾的常见原因。
比较静态拉伸（SS）、自生抑制（AI）和交互抑制（RI）肌肉能量技术（MET）对机械性颈部疼痛管理中等长肌肉力量的即刻和短期效果。
对 78 名颈部疼痛患者进行了一项随机对照试验，将他们随机分配到 SS、AI-MET 和 RI-MET 组。所有参与者均接受经皮神经电刺激（TENS）、热敷和单侧前后滑动，然后连续 5 天进行 3-5 次 SS、AI-MET 或 RI-MET。数字疼痛评分量表（NPRS）和改良血压计动态测力量表（MSD）被用作结果测量工具。使用单向方差分析和重复测量方差分析进行组间和组内比较。
在 MSD 评分方面，组间存在显著差异（p<0.05）。AI-MET 和 RI-MET 均比 SS 更有效，但 AI-MET 更有效。
AI-MET 在改善机械性颈部疼痛患者等长肌肉力量方面比 SS 和 RI-MET 更有效。
