Abstract

BACKGROUND

The impact of computer typing in a slump posture on pain, proprioception and muscle recruitment has not been extensively investigated. Therefore, the purpose of this study was to evaluate the extent of pain, proprioception and muscle activity resulting from computer typing in a slump posture in women who already suffer from chronic neck pain.

METHODS

This cross-sectional study was conducted between May 20 to July 10, 2021. A total of 15 female 42-(±4.96)-year-old office workers with chronic non-specific neck pain participated in this study. Before and after 60 min of computer typing in a slump posture, proprioception and pain were measured using an inclinometer and visual analog scale (VAS), respectively. The activity of the cervical erector spine (CES) and upper trapezius (UT) muscle was also measured before and after the slump-posture computer typing, in upright, forward, and slump postures. RESU: lts: Paired-samples t-tests showed that pain was increased and proprioception in all directions (flexion, extension, right and left lateral flexion, and right, and left rotation) was less accurate (P < 0.05) after 60 min computer typing. The CES and UT muscle activity were elevated more in the forward head and slump posture than in the upright posture (P < 0.05).

CONCLUSION

Sixty minutes computer typing in a slump posture increased neck pain, resulted in a decreased proprioception in the neck and was accompanied by an increased activity of the neck musculature.

摘要

背景

在低头姿势下使用电脑打字对疼痛、本体感觉和肌肉募集的影响尚未得到广泛研究。因此，本研究的目的是评估已经患有慢性颈痛的女性在低头姿势下使用电脑打字引起疼痛、本体感觉和肌肉活动的程度。

方法

这是一项横断面研究，于 2021 年 5 月 20 日至 7 月 10 日进行。共有 15 名 42 岁（±4.96 岁）的患有慢性非特异性颈痛的办公室女性工作人员参与了本研究。在低头姿势下使用电脑打字 60 分钟前后，分别使用倾斜计和视觉模拟量表（VAS）测量本体感觉和疼痛。还在直立、前倾和低头姿势下测量了颈伸肌（CES）和上斜方肌（UT）的肌肉活动。
