Studies on work-related musculoskeletal symptoms (WRMSs) have been conducted mainly on different types of workforce but not many on low-skilled workers. The purpose of this study was to evaluate the effectiveness of a multidisciplinary exercise program in decreasing the number of body parts with WRMSs for low-skilled workers. This study used a repeated-measures, single-group design. One hundred and five (105) workers participated in eight weekly 90-min sessions (including 45-min workshops and 45-min exercises) in low-income community settings. The exercise program involved a 21-movement stretching exercise and a 10-movement muscle-strengthening exercise. Questionnaire and health-assessment data were collected at the baseline (N = 105) and immediately after the 8-week program (n = 86). The average age of the 105 participants was 50.5 ± 8.7 years (ranging from 31 to 67). Over 80% (n = 87) of them were female, 68.6% (n = 72) were married, and 68.6% (n = 72) had completed secondary school. They reported an average of three body parts with WRMSs at baseline (T0). By the end of the eight weeks (T1), the participants had reduced the number of WRMS-affected body parts, job stress, and incidences of working through pain, and had improved spine flexibility and handgrip strength. The factors significantly affecting the reduction in the number of body parts with WRMSs were change in the workstyle of working through pain, and self-rated health status. Our study has demonstrated that a community-based multidisciplinary program can reduce the number of body parts affected by WRMSs in low-skilled workers in low-income communities.
本研究旨在评估多学科运动方案对减少低技能工人工作相关肌肉骨骼症状（WRMSs）身体部位数量的有效性。本研究采用重复测量、单组设计。105 名工人参加了在低收入社区环境中每周 8 次、每次 90 分钟的课程（包括 45 分钟的工作坊和 45 分钟的锻炼），共 8 周。运动方案包括 21 个动作拉伸运动和 10 个动作肌肉强化运动。在基线（N=105）和 8 周方案结束时（n=86）收集问卷和健康评估数据。105 名参与者的平均年龄为 50.5±8.7 岁（年龄范围为 31-67 岁）。超过 80%（n=87）为女性，68.6%（n=72）已婚，68.6%（n=72）完成了中学学业。他们在基线（T0）时报告平均有 3 个身体部位出现 WRMSs。到 8 周结束时（T1），参与者减少了受 WRMS 影响的身体部位数量、工作压力以及强忍疼痛工作的发生率，并且提高了脊柱灵活性和手握力。显著影响 WRMSs 身体部位减少的因素为改变强忍疼痛工作的工作方式和自评健康状况。本研究表明，基于社区的多学科方案可以减少低收入社区低技能工人的 WRMSs 身体部位数量。
