颈椎肌肉活动模式可能导致办公室工作人员过度使用损伤。本研究的目的是使用传统的职业暴露措施和修改后的活动幅度概率分布函数（APDF），它只考虑主动肌肉收缩的时期，在无痛办公室工作人员的上睑肌活动的特征模式。在77名无痛办公室工作人员的自然工作环境中记录了1-2整天的双侧阔肌活动。计算平均振幅、间隙频率、肌肉静息以及传统和主动APDF振幅。所有测量均显示出相当可靠性。与非优势肌相比，优势肌表现出更高的活动幅度和更少的肌肉休息，女性表现出更少的肌肉休息，与男性相比，主动APDF评估的幅度没有显著差异。这些研究结果提供了规范性数据，以确定非典型的运动模式，可能有助于持续或复发的颈部疼痛的办公室工作人员。在一个大的队列的无痛工人使用肌电图记录从办公室环境中的上阔肌肌活动的特点。优势肌肉表现出更高的活动和更少的休息比非优势，女性表现出更少的休息比男性。结果可用于识别办公室工作人员的非典型肌活动。
Patterns of cervical muscle activity may contribute to overuse injuries in office workers. The purpose of this investigation was to characterize patterns of upper trapezius muscle activity in pain-free office workers using traditional occupational exposure measures and a modified Active Amplitude Probability Distribution Function (APDF), which considers only periods of active muscle contraction. Bilateral trapezius muscle activity was recorded in 77 pain-free office workers for 1–2 full days in their natural work environment. Mean amplitude, gap frequency, muscular rest, and Traditional and Active APDF amplitudes were calculated. All measures demonstrated fair to substantial reliability. Dominant muscles demonstrated higher amplitudes of activity and less muscular rest compared to non-dominant, and women demonstrated less muscular rest with no significant difference in amplitude assessed by Active APDF compared to men. These findings provide normative data to identify atypical motor patterns that may contribute to persistence or recurrence of neck pain in office workers. Upper trapezius muscle activity was characterized in a large cohort of pain-free workers using electromyographic recordings from office environments. Dominant muscles demonstrated higher activity and less rest than non-dominant, and women demonstrated less rest than men. Results may be used to identify atypical trapezius muscle activity in office workers.
