Effects of Postural Changes Using a Standing Desk on the Craniovertebral Angle, Muscle Fatigue, Work Performance, and Discomfort in Individuals with a Forward Head Posture.

Abstract

Forward head posture is common among office workers who sit for long periods of time and is one of the main causes of neck pain. This study aimed to assess the effects of utilizing a standing desk on the craniovertebral angle, muscle fatigue, work performance, and discomfort in individuals with forward head posture. Twenty-four participants meeting the inclusion criteria were randomly assigned to either a traditional desk group (n = 12) or a standing desk group (n = 12). Each group engaged in 30 min of computer typing. To evaluate the impact of posture change using a standing desk, pre- and post-experiment discomfort surveys were conducted, and the craniovertebral angle and muscle fatigue were measured throughout the experiment. Work performance was assessed post-experiment based on the work completed by the participants. Intra-group analysis of the craniovertebral angle showed a significant decrease in the traditional desk group (p < 0.05) and a significant increase in the standing desk group (p < 0.05). When comparing the craniovertebral angle between the two groups, a significant difference was observed (p < 0.05). Additionally, significant differences in muscle fatigue, particularly in the levator scapulae muscles, were observed between the two groups (p < 0.05). The traditional desk group reported increased discomfort in the neck and shoulders (p < 0.05). These findings suggest that utilizing a standing desk can positively impact posture, reduce muscle fatigue, and alleviate discomfort in individuals with forward head posture, potentially serving as an intervention to prevent musculoskeletal disorders.
