Motorcycle Riders' Pain Scale: New Tool Shows Strong Reliability

Researchers set out to create a quick screening tool for musculoskeletal problems among motorcyclists. They gathered data from 140 riders in Tunisia. Each participant rated pain in nine different body regions using a four‑point scale. The goal was to capture how often and how intensely riders felt discomfort.

The analysis revealed two clear factors. One factor covered the upper body, the other the lower body. Together they explained 67.5 percent of the total variance. Internal consistency was excellent, with Cronbach alphas of 0.910 and 0.881. Statistical tests strongly favored the two‑factor model over a single‑factor approach. Factor loadings ranged from 0.75 to 0.91, and the approximation error measured 0.103.

Further examination showed that engine displacement made a difference on both subscales. The effect size was moderate, with a partial eta squared of 0.196. Age groups differed only for upper‑body pain, with a p‑value of 0.007. Riding discipline did not produce a significant impact, as indicated by a p‑value of 0.183.

Overall, the new scale presents a coherent two‑factor structure and high internal consistency. While the model fit is solid, it falls just short of the ideal approximation‑error threshold. The tool appears ready for practical use in screening motorcycle operators for musculoskeletal disorders.
