Neck and shoulder pain and disorders were studied among frequent computer users, and the associated effect of mouse and keyboard use was evaluated.
Technical assistants and machine technicians were followed for 1 year. Questionnaires were sent to 9480 persons (initial response 73%, follow-up response 82%). Computer use information was obtained from the questionnaires. Symptom cases at baseline and follow-up were clinically examined using a standardized clinical protocol. The main outcomes were self-reported pain symptoms in the neck and right shoulder and clinical cases of rotator cuff syndrome, tension neck syndrome, and neck-shoulder pain with pressure tenderness.
The prevalence of moderate-to-severe pain in the neck and right shoulder was 4.1% and 3.4%, respectively, and the 1-year incidence for no or minor baseline symptoms was 1.5% and 1.9%, respectively. At baseline, the prevalence rate ratio (PRR) for neck pain was 1.7 [95% confidence interval (95% CI) 1.1-2.6] for mouse use >25 hours/week, that for right shoulder pain increased from 1.6 (95% CI 1.1-2.4) for 15-19 hours/ week to 2.5 (95% CI 1.4-4.3) for >30 hours/week of mouse use, and that for tension neck syndrome increased from 3.5 (95% CI 1.0-12) for 25-29 hours/week to 4.7 (95% CI 1.2-18) for >30 hours/week of mouse use. The relative risk (RR) for new neck pain was 1.8 (95% CI 0.8-3.9) for keyboard use > or = 15 hours/week and increased to 2.4 (95% CI 0.8-6.8) for > or = 30 hours/week. New right-shoulder pain symptoms were associated with mouse use >20 hours/week (RR 1.9, 95% Cl 1.0-3.5, and RR 3.3, 95% CI 1.2-8.9) and with keyboard use >15 hours/week (RR 2.2, 95% CI 1.0-4.9).
Mouse use is associated with an increased risk of moderate-to-severe pain in the neck and right shoulder, and an association with tension neck syndrome is possible.
对频繁使用电脑人群的颈部和肩部疼痛及疾病进行研究，并评估使用鼠标和键盘的相关影响。
对技术助理和机器技术员进行为期1年的跟踪调查。向9480人发放问卷（初始回复率73%，随访回复率82%）。从问卷中获取电脑使用信息。在基线和随访时，采用标准化临床方案对症状病例进行临床检查。主要结局为自我报告的颈部和右肩部疼痛症状，以及肩袖综合征、紧张性颈综合征和伴有压痛的颈肩痛的临床病例。
颈部和右肩部中重度疼痛的患病率分别为4.1%和3.4%，基线时无或仅有轻微症状者的1年发病率分别为1.5%和1.9%。在基线时，每周使用鼠标>25小时者颈部疼痛的患病率比值比（PRR）为1.7[95%置信区间（95%CI）1.1 - 2.6]，每周使用鼠标15 - 19小时者右肩部疼痛的PRR为1.6（95%CI 1.1 - 2.4），而每周使用鼠标>30小时者该比值增至2.5（95%CI 1.4 - 4.3）；每周使用鼠标25 - 29小时者紧张性颈综合征的PRR为3.5（95%CI 1.0 - 12），每周使用鼠标>30小时者该比值增至4.7（95%CI 1.2 - 18）。每周使用键盘≥15小时者新发颈部疼痛的相对风险（RR）为1.8（95%CI 0.8 - 3.9），每周使用键盘≥30小时者该风险增至2.4（95%CI 0.8 - 6.8）。新发右肩部疼痛症状与每周使用鼠标>20小时相关（RR 1.9，95%CI 1.0 - 3.5，以及RR 3.3，95%CI 1.2 - 8.9），也与每周使用键盘>15小时相关（RR 2.2，95%CI 1.0 - 4.9）。
使用鼠标与颈部和右肩部中重度疼痛风险增加相关，且可能与紧张性颈综合征有关。
