This study is expected to contribute the baseline of possile association between postural angles and development of musculoskeletal disorders (MSDs) among food delivery services (P-hailing riders) in Taiping, Perak. The objective of the research was to find out the relationship between P-hailing ergonomic risk factors while riding a motorcycle and the prevalence of WMSDs.

The chi-square test was used to determine an association postural angle between prevalence of WMSDs. Based on the outcome, the result found that there was significant relationship p-value < 0.05 between postural angle and the prevalence of WMSDs for neck, shoulders, upper back and lower back, thighs, wrists and ankles. The p-value for the elbows and knees is more than 0.05, that indicates there was no significant relationship between postural angles and the prevalence of WMSDs.
