Since musculoskeletal disorders of the upper extremities are believed to be associated with repetitive excessive muscle force production in the hands, understanding the time-dependent muscle forces during key tapping will help to explore the mechanisms of disease initiation and development. Because the experimental evaluation of the dynamic loading in individual muscles of the hand during typing is technically difficult and expensive, researchers have studied the dynamic contact force between the fingertip and keypad, and joint angle motions, and assumed that these indices are related to the muscle/tendon excursions. The goal of the current study is to analyze the dynamic muscle forces in an index finger during typing using a universal finger model developed on a platform of the commercial software package AnyBody (AnyBody Technology Inc., Aalborg, Denmark).
