Association of Manual Weight Lifting Tasks with Low Back Pain: A Pilot Study
Journal of Clinical and Diagnostic Research
Manual Weight Lifting (MWL) and Low Back Pain (LBP) become closely interrelated when lifting tasks are performed without adhering to lifting norms. Maximum trauma during MWL is encountered by lower body joints which absorb force proportional to the weight being lifted. Therefore, quantification of the injury potential of such tasks in terms of kinetic responses would prove beneficial for further designing of MWL tasks with reduced incidences of LBP. Aim: To quantify the kinetic responses of
... ic responses of lifting tasks using real-time data collection technique and to find out whether real-time kinetics data corroborated with 2D prediction kinetics data analysed using simultaneously recorded 2D images of MWL. Materials and Methods: This cross-sectional pilot study was conducted on eight healthy participants. Hand grip strength, videos for prediction kinetics and real-time kinetics data were recorded with hand grip calliper, Sony handy cam, and Kistler Force Plate, respectively. Prediction kinetics data from still photographs were extracted and analysed using ergonomics evaluation software ErgoMaster. Real-time Kinetics data were analysed with BioWare(R) software. Repeated measure Analysis of Variance (ANOVA) followed by Bonferroni post-hoc test was applied for statistical treatment.
