Prevalence causes and impact of work related musculoskeletal disorders among physical therapists

Abstract

BACKGROUND:

Physical therapists are particularly vulnerable to work-related musculoskeletal disorders (WRMDs).

OBJECTIVE:

To evaluate the prevalence, causes and impact of WRMDs among physical therapists in the Kingdom of Saudi Arabia (KSA).

METHODS:

A cross-sectional study of physical therapists using a valid and reliable questionnaire. A total of 690 completed surveys were returned (response rate = 69%). The T-test and Pearson's correlation were used to identify correlations between variables and the incidence of WRMDs.

RESULTS:

Working hours/week and WRMDs were significantly correlated(p = 0.005). Lower back (46.5%) and neck (26.6%) pain were most commonly encountered. WRMDs were significantly correlated with altered work habits (p = 0.036) but not with body mass index (p = 0.297). The prevalence of WRMDs among physical therapists was 47.7% with a significant difference between full- and part-time practice (p = 0.023). Adjustable beds/plinths(20%) and splints (18%) were the most commonly used assistive devices.

CONCLUSIONS:

Physical therapists are especially vulnerable to WRMDs with a prevalence of 47.7%. WRMDs are impacted by both work status and setting. Low back pain is the most common form of WRMDs (46.5%). Avoidance of poor work habits, increased ergonomic awareness and application of safety measures are essential to prevent WRMDs.
