Abstract

Three lift postures of straight back, bent back and squatting were evaluated by obtaining subject's opinion on the site, intensity and frequency of pain after holding the maximum load for one and two minutes. The study was based on a sample of 100 adult Koli female labourers. Most of the subjects reported knee pain in straight back posture, pain in the lower part of the back in the bent back posture, and pain in the lower arm in squatting posture. In the majority of the subjects, the site of pain remained unchanged for one minute and two minutes of weight holding. Since the intensity and the frequency of pain after holding the load for one and two minutes were the least in the straight back and squatting postures, they were judged to be the best postures for repetitive and continuous holding tasks, respectively.
