Abstract

Context: Forward shoulder posture (FSP) is a risk factor for shoulder pathology. Manual therapists often use myofascial release (MFR) to elongate restricted pectoral fascia to reduce FSP and improve shoulder function; however, the effects of this treatment approach remain anecdotal.

Objective: Determine the acute effects of 4-min of MFR, compared to a soft-touch control (CON), to the pectoral fascia on: 1) FSP, 2) shoulder horizontal abduction ROM (HA-ROM), and 3) muscle excitation of the trapezius (upper, middle, lower [UT, MT, LT]) and pectoralis major (PEC).

Methods: Fifty-nine right-handed participants (27 ± 9 years, 30 female) with FSP, but otherwise asymptomatic shoulders participated in a randomized crossover clinical trial by attending two experimental sessions: one MFR and one CON treatment, each administered by a Registered Massage Therapist. FSP, HA-ROM, and muscle excitation during a reaching task, were measured before and after each treatment.

Results: There was a significant interaction between treatment and time for FSP (p = .018, η_p = .093) with FSP decreasing from PRE MFR (128 ± 19 mm) to POST MFR (123 ± 19 mm; p < .001, η_p = .420) and PRE CON (126 ± 19 mm) to POST CON (124 ± 18 mm; p < .001, η_p = .191) interventions. There were no significant differences in HA-ROM or muscle excitation.

Conclusion: Four minutes of MFR or CON to the pectoral fascia acutely reduces FSP.

胸肌筋膜松解术对姿势、活动范围和肌肉兴奋性的直接影响：一项交叉随机临床试验。

背景：肩关节前倾（FSP）是肩关节病变的一个危险因素。手法治疗师经常使用肌筋膜松解术（MFR）来拉长受限的胸肌筋膜，以减少前倾姿势并改善肩部功能；然而，这种治疗方法的效果仍是传闻：目标：与软接触对照组（CON）相比，确定对胸肌筋膜进行 4 分钟 MFR 的急性效果：1) FSP，2) 肩部水平外展 ROM (HA-ROM)，3) 斜方肌（上、中、下 [UT、MT、LT]）和胸大肌 (PEC) 的肌肉兴奋：59 名患有 FSP 的右撇子参与者（27 ± 9 岁，30 名女性）参加了一项随机交叉临床试验，他们参加了两个实验疗程：一个 MFR 疗程和一个 CON 疗程，每个疗程由一名注册按摩师实施。在每次治疗前后，均测量了FSP、HA-ROM和伸手任务中的肌肉兴奋度：FSP（p = .018，ηp = .093）在治疗和时间之间存在明显的交互作用，FSP从治疗前的MFR（128 ± 19 mm）下降到治疗后的MFR（123 ± 19 mm；p p = .420），从治疗前的CON（126 ± 19 mm）下降到治疗后的CON（124 ± 18 mm；p p = .191）。HA-ROM 或肌肉兴奋性无明显差异：结论：对胸肌筋膜进行四分钟的 MFR 或 CON 可急性降低 FSP。
