Nonspecific chronic neck pain (ns-CNP) is a common cause of disability among office workers. However, the effectiveness of tissue release and stretching strategies in managing pain and fatigue of neck muscles in employees affected by ns-CNP has not been assessed.
Thirty-nine employees who suffered from ns-CNP were randomly assigned to stretching, tissue release interventions or control group ( = 13). Neck pain and fatigue in neck extensors, upper trapezius, and sternocleidomastoid muscles were measured during 40 min of typing with a 45-degree head flexion at baseline and immediately after a 6-week intervention using visual analog scale and surface electromyography.
Pain significantly decreased after 6 weeks of both interventions ( < 0.05). There were no significant within-group differences for right cervical muscle fatigue in the intervention groups, but a significant difference was noted in the control group at the 25th and 40th minutes ( < 0.05). Additionally, a significant difference was observed between the release and control group at the 30th, 35th, and 40th minutes ( < 0.05). Left cervical muscle fatigue significantly decreased at the 25th and 40th minutes only for the release group ( < 0.05). A significant difference was observed between the release and control groups at the 40th minute for the right upper trapezius ( < 0.05).
Only the stretching group showed a significant difference with the control in the left sternocleidomastoid at the 10th and 15th minutes, and the release group with the control in the last 5-min. Stretching and release interventions could control neck pain and muscle fatigue in the 45-degree head flexion position.
非特异性慢性颈部疼痛（ns-CNP）是上班族残疾的常见原因。然而，组织松解和拉伸策略对受ns-CNP影响的员工颈部肌肉疼痛和疲劳的管理效果尚未得到评估。
39名患有ns-CNP的员工被随机分配到拉伸组、组织松解干预组或对照组（每组13人）。在基线时以及6周干预结束后，使用视觉模拟量表和表面肌电图，在45度头部前屈打字40分钟期间测量颈部伸肌、上斜方肌和胸锁乳突肌的颈部疼痛和疲劳情况。
两种干预6周后疼痛均显著降低（P<0.05）。干预组右侧颈部肌肉疲劳在组内无显著差异，但对照组在第25分钟和第40分钟有显著差异（P<0.05）。此外，在第30分钟、第35分钟和第40分钟，松解组与对照组之间存在显著差异（P<0.05）。仅松解组在第25分钟和第40分钟时左侧颈部肌肉疲劳显著降低（P<0.05）。在第40分钟时，右侧上斜方肌松解组与对照组之间存在显著差异（P<0.05）。
仅拉伸组在第10分钟和第15分钟时，左侧胸锁乳突肌与对照组相比有显著差异，松解组在最后5分钟与对照组相比有显著差异。拉伸和松解干预可控制45度头部前屈位时的颈部疼痛和肌肉疲劳。
