Muscle strength, task performance and low back load in nurses
Article Abstract:
A study was performed to evaluate the relationship between muscle strength, task performance and lower back pain (LBP) incidence among nurses through muscle strength tests of the main trunk extensors done on a dynamometer. Two mechanisms were considered in explaining how muscle strength influences risk of LBP, namely, inefficiency of task performance and mechanical load on low back level. Results revealed that muscle strength was not affected by task performance or low back load. Higher risk of LBP was attributed to reduced capability against mechanical load rather than increased mechanical load.

Quantification of the static load component in muscle work using nonlinear filtering of surface EMG
Article Abstract:
The analysis of the nature and static aspects of muscular work on the basis of EMG can be utilized to identify the muscles vulnerable to harmful static or dynamic overload during work. To determine the static strain with the help of electromyography (EMG), the level and the period of the muscle load should be analysed on temporal basis. A model for doing so is tested and results are discussed in detail.
