Associations between work-related musculoskeletal disorders, quality of life, and workplace stress in physical therapists

Abstract

This study was performed to determine the associations between work-related musculoskeletal disorders (WMSDs), quality of life (QoL), and workplace stress among physical therapists (PTs) in South Korea. Self-reporting questionnaires were given to 855 PTs. Variables examined included general characteristics, WMSDs, QoL, and workplace stress. Of the 788 PTs who responded, 745 (94.5%) reported WMSDs affecting at least one body site. The most affected WMSDs site was the shoulder (23.3%), and the most reported number of body sites affected by WMSDs was one (50.9%). QoL was significantly improved (p<0.05) among PTs over 39 years old, who had 10-15 years of professional experience, worked in general/university hospitals, and had only one site affected by WMSDs. Factors influencing QoL included number of body sites affected by WMSDs, presence/absence of WMSDs, working venues, workplace stress, and age. Factors affecting workplace stress included number of body sites affected by WMSDs, QoL, work hours, and gender. The results showed a high prevalence of WMSDs among PTs in South Korea, and this negatively affected both QoL and workplace stress.
