摘要: Police officers spend large amounts of time performing duties within a police cruiser and report high prevalence musculoskeletal problems. This study evaluated the effects driver seat duty belt design on posture, pressure discomfort. Ten male 10 female university students attended two sessions involving simulated driving in standard (CV) an active lumbar support (ALS) seat. Participants wore full (FDB) or reduced (RDB) each Lumbar postures, driver-seat driver-duty pressures perceived discomfort were measured. Gender × Seat interactions found for pelvic (p = 0.0001) postures (p = 0.003). Females had more flexion than males extended ALS (−9.8 ± 11.3°) CV (−19.8 ± 9.6°). The FDB greater RDB (p < 0.0001), which corresponded to increased pelvis supports use reduce injury risk associated with p...
