Morphological variables as possible risk factors for low back pain

The prevalence of lower back disorders and the high costs involved are an ongoing problem in industrialised countries. Research indicates an estimated 70-80% of all individuals will experience lower back pain (LBP) during the course of their lives. It is widely accepted that occupational demands and physical work contribute greatly towards onset, recovery and recurrence of symptoms. Rubber Tyred Gantry (RTG) crane drivers are particularly at risk, as their working posture forces them into various prolonged non-neutral trunk positions and extreme trunk flexion. Intrinsic factors such as trunk strength and trunk stability as well as anthropometric variables, can play different roles in incidences of lumbar pain or injury. A job such as RTG crane driving is dependant on a certain amount of strength or physical fitness. A deficit in on or more of these areas can lead to compensation, overload and eventually symptoms and injury. Research has yet to identify factors that predispose certain drivers to injury, and factors determining a quick, safe recovery and return to work.... Mehr
