Many long term wheelchair users develop shoulder pain. The purpose of this study was to examine the reliability and validity of the Wheelchair User's Shoulder Pain Index (WUSPI), an instrument which measures shoulder pain associated with the functional activities of wheelchair users. This 15-item functional index was developed to access shoulder pain during transfers, self care, wheelchair mobility and general activities. To establish test-retest reliability, the index was administered twice in the same day to 16 long term wheelchair users and their scores for the two administrations were compared by intraclass correlation. To establish concurrent validity, the index was administered to 64 long term wheelchair users and index scores were compared to shoulder range of motion measurements. Results showed that intraclass correlation for test-retest reliability of the total index score was 0.99. There were statistically significant negative correlations of total index scores to range of motion measurements of shoulder abduction (r = -0.485), flexion (r = -0.479) and shoulder extension (r = -0.304), indicating that there is a significant relationship of total index score to loss of shoulder range of motion in this sample. The Wheelchair User's Shoulder Pain Index shows high levels of reliability and internal consistency, as well as concurrent validity with loss of shoulder range of motion. As a valid and reliable instrument, this tool may be useful to both clinicians and researchers in documenting baseline shoulder dysfunction and for periodic measurement in longitudinal studies of musculoskeletal complications in wheelchair users.
许多长期使用轮椅的人会出现肩部疼痛。本研究的目的是检验轮椅使用者肩部疼痛指数（WUSPI）的可靠性和有效性，该指数用于衡量与轮椅使用者功能活动相关的肩部疼痛。这个包含15个项目的功能指数旨在评估转移、自我护理、轮椅移动和日常活动期间的肩部疼痛。为了确定重测信度，该指数在同一天对16名长期轮椅使用者进行了两次测量，并通过组内相关分析比较了两次测量的得分。为了确定同时效度，该指数对64名长期轮椅使用者进行了测量，并将指数得分与肩部活动范围测量结果进行了比较。结果显示，总指数得分的重测信度组内相关系数为0.99。总指数得分与肩外展活动范围测量值（r = -0.485）、屈曲（r = -0.479）和肩伸展（r = -0.304）之间存在统计学显著的负相关，表明在该样本中总指数得分与肩部活动范围丧失之间存在显著关系。轮椅使用者肩部疼痛指数显示出高度的可靠性和内部一致性，以及与肩部活动范围丧失的同时效度。作为一种有效且可靠的工具，该工具可能对临床医生和研究人员在记录基线肩部功能障碍以及在轮椅使用者肌肉骨骼并发症纵向研究中的定期测量方面都有用处。
