Upper extremity injured workers are an under-studied population. A descriptive comparison of workers with shoulder, elbow and hand injuries reporting to a Canadian Workplace Safety and Insurance Board (WSIB) clinic was undertaken.
To determine if differences existed between injury groups stratified by current work status.
All WSIB claimants reporting to our upper extremity clinic between 2003 and 2008 were approached to participate in this descriptive study. 314 working and 146 non-working WSIB claimants completed the Disabilities of the Arm, Shoulder and Hand questionnaire (DASH); Short Form health survey (SF36); Worker's Limitations Questionnaire and the Work Instability Scale. Various parametric and non-parametric analyses were used to assess significant differences between groups on demographic, work and health related variables.
Hand, followed by the shoulder and elbow were the most common site of injury. Most non-workers listed their current injury as the reason for being off work, and attempted to return to work once since their injury occurrence. Non-workers and a subset of workers at high risk for work loss showed significantly worse mental functioning. Workers identified physical demands as the most frequent injury-related on the job limitation. 60% of current workers were listed as low risk for work loss on the Work Instability Scale.
Poorer mental functioning, being female and sustaining a shoulder injury were risk factors for work instability. Our cohort of injured non-workers were unable to return to work due to their current injury, reinforcing the need to advocate for modified duties, shorter hours and a work environment where stress and injury recurrence is reduced. Future studies examining pre-injury depression as a risk factor for prolonged work absences are warranted.
上肢受伤工人是一个研究不足的群体。对向加拿大工作场所安全与保险委员会（WSIB）诊所报告肩部、肘部和手部受伤情况的工人进行了描述性比较。
确定按当前工作状态分层的受伤群体之间是否存在差异。
邀请2003年至2008年间向我们上肢诊所报告的所有WSIB索赔人参与这项描述性研究。314名在职和146名非在职WSIB索赔人完成了手臂、肩部和手部残疾问卷（DASH）；简短健康调查问卷（SF36）；工人限制问卷和工作不稳定性量表。使用各种参数和非参数分析来评估各组在人口统计学、工作和健康相关变量上的显著差异。
手部是最常见的受伤部位，其次是肩部和肘部。大多数非工人将其当前受伤列为缺勤原因，自受伤以来曾尝试重返工作岗位一次。非工人和有工作损失高风险的一部分工人的心理功能明显较差。工人将身体需求确定为与工作限制相关的最常见受伤因素。在工作不稳定性量表上，60%的在职工人被列为工作损失低风险。
心理功能较差、女性以及肩部受伤是工作不稳定的风险因素。我们这组受伤的非工人因当前受伤而无法重返工作岗位，这进一步凸显了倡导调整工作职责、缩短工作时间以及营造压力和受伤复发率较低的工作环境的必要性。有必要开展未来研究，将受伤前的抑郁症作为长期缺勤的风险因素进行研究。
