Force exertion is critical in grasping and holding activities at sub-maximal levels. Exertion misjudgments lead to musculoskeletal disorders (MSDs) impairing performance and productivity. Published literatures on grasping have addressed the force balance and endurance issues for non-prehensile movements of hand. However, little information is available on the force exerted in precision gripping employed in health care. Professionals, especially dental hygienists, when treating patients adopt awkward postures for extended period leading to cumulative trauma. Literatures on cumulative trauma have identified force exertion to be an important risk factor. Lack of information on fatigue with precision gripping motivated this research to establish …
