Description
Applied grip force is an important factor in the design of safe jobs in industry. Unfortunately, grip force is very difficult to measure in occupational environments. Maximum voluntary contraction (MVC) for static grip strength is commonly reported; however, many activities require dynamic contractions and little information is available for maximum dynamic grip strength. This study uses a static and custom built dynamic strength testing device to measure grip force and surface electromyography (sEMG) to measure muscle activity during maximum voluntary contraction (MVC). Specifically, the effects of grip span on MVC for both static (isometric) and dynamic (isotonic) contractions will be tested. The purpose of this study is to quantify the difference in MVC associated with changes in grip span and to determine the relationship between static and dynamic MVCs. In addition, it will help us to further develop surface EMG as a tool for measuring applied grip force.
