A VIDEO RECORDING SPINE MOTION ANALYSIS COULD DETECT FATIGUE ACCUMULATION

Introduction One of the most important health problems in industry is the onset of low back pain (LBP) due to the musculoskeletal fatigue after repetitive even light weight lifting tasks [MacDonald, 2008]. The posture as well as the number of lifting repetitions play an important role to the muscle fatigue. The existing muscle fatigue assessment methods (i.e. electromyography) are restricted by the cost of the collection equipment, environmental constraints and access to employees [Parkinson, 2010]. In this work a simple, non invasive and cost-effective method was used. The purpose of this study was to detect changes in the kinematic parameters which might imply accumulation of muscle fatigue which contribute to LBP.
