Comparison of low back joint moment using a dynamic 3D biomechanical model in different transferring tasks wearing low back belt.
The purpose of this study was to construct a 3D dynamic model to quantify low back load during single person dependent transfer, and to compare the effects of wearing style of a low back belt on low back loading. Of the nine subjects participating in this study, eight adopted the role of caregiver and one was a simulated patient. Tasks were general transfer without either subject wearing a low back belt (WB), transfer with the patient wearing a low back belt (BP), transfer with both subjects wearing low back belts (BB), and transfer with the caregiver wearing a low back belt (BC). Low back lateral and extension moments in BB and BC transfers showed the significantly smaller values than those in WB transfers (p<0.01). The results suggest that the wearing of a low back belt by caregivers would reduce low back joint moment during transfers.
