Muscle strength, task performance and low back load in nurses

摘要

Poor muscle strength, relative to the physical demands of specific jobs, is considered a risk factor for low back pain. To gain an understanding of the underlying mechanisms, this study questioned whether muscle strength was related to task performance and low back load in nursing tasks. Trunk extension, elbow flexion and knee extension strength were therefore measured in 17 nurses. The independent effects of muscle strength on task duration jerkiness of effort And L5-S1 torque were investigated as the nurses performed several patient Handling tasks.
