摘要
背景：使用振动刺激进行干预具有在不影响肌肉力量的情况下增加运动范围（ROM）的潜力，这一点已得到认可。目的：评估使用手持设备进行振动按摩对肩关节后部软组织的影响，尤其是对内旋（IR）被动活动范围和外旋（ER）肌肉力量的影响：研究设计：交叉研究设计：在健康男性志愿者（平均年龄为 20.5 ± 1.7 岁）中进行了一项为期 5 分钟的振动按摩和被动控制条件的交叉研究。振动按摩作用于优势手臂的肩部后侧软组织，对照组不进行任何干预。干预前和干预后立即测量 IR-ROM（椎体水平和外展）和外旋肌力量（等长和等动）。椎体水平是以长度比来计算的（随着活动度的增加，比值减小）。测量外展时的 IR-ROM 角度。统计分析采用双向重复测量方差分析和配对 t 检验（Bonferroni 校正）：结果：振动使椎体水平 IR ROM 减少（改善）-4.1%（p < 0.01，d = 0.445），外展位置 IR ROM 增加 11.4°（p < 0.01，d = 0.694）。这些变化超过了最小可检测变化的 95% 置信区间。相比之下，对照组则没有任何变化。干预后立即进行的 IR-ROM（椎体水平和外展）在对照组和振动组之间存在显著差异（分别为 p = 0.036，d = 0.273；p = 0.048，d = 0.483）。肌肉力量未显示出任何交互作用、时间或条件间效应：结论：使用手持振动按摩器对肩部后侧软组织进行按摩可增加 IR-ROM，而不会对肌肉力量产生负面影响，这表明振动按摩器有可能用作热身手段：证据等级：3 级。
Acute Effects of Handheld Vibration Massage on Posterior Shoulder Soft Tissues.
Background: Interventions using vibration stimulation have been recognized for their potential for increasing range of motion (ROM) without compromising muscle strength. Handheld vibration massagers can efficiently deliver vibration therapy to the shoulder joint and may be a potential treatment.
Purpose: To evaluate the effects of vibration massage using a handheld device on the soft tissues of the posterior shoulder joint, particularly on internal rotation (IR) passive ROM and external rotation (ER) muscle strength.
Study design: Crossover study design.
Methods: A crossover study with a 5-min vibration massage and passive control condition was conducted in healthy male volunteers (mean age 20.5 ± 1.7 years). Vibration massage was applied to the posterior shoulder soft tissues of the dominant arm, with no intervention under control conditions. IR-ROM (vertebral level and in abduction) and strength of the external rotators (isometric and isokinetic) were measured before and immediately after the intervention. Vertebral levels were calculated as a ratio of lengths (ratio decreases with increased mobility). IR-ROM in abduction, the angle was measured. Statistical analysis was performed with two-way repeated measures ANOVA and paired t-test (Bonferroni correction).
Results: Vibration application decreased (improved) vertebral level IR ROM by -4.1% (p < 0.01, d = 0.445) and increased abduction position IR ROM by 11.4° (p < 0.01, d = 0.694). These changes exceeded the 95% confidence interval for the minimum detectable change. By contrast, the control condition produced no changes. IR-ROM (vertebral level and abduction) immediately after the intervention showed significant differences between the control and vibration conditions (p = 0.036, d = 0.273; p = 0.048, d = 0.483, respectively). Muscle strength did not show any interaction, time, or between-condition effects.
Conclusions: A massage using a handheld vibration massager applied to the posterior shoulder soft tissues increased IR-ROM without negatively affecting muscle strength, suggesting its potential use as a means of warming up.
