• Description:
  Forceful exertion of tendons while gripping hand tools may be one of the factors that lead to the development of work-related musculoskeletal disorders (WRMSDs). Previous research has indicated that flexor digitorum profundus (FDP) and flexor digitorum superficialis (FDS) tendon forces can be up to 3.7 times the external forces. These values are indirect estimates derived from biomechanical models developed for the hand. However, these include many assumptions and may not be accurate. Therefore, it is imperative that the model is validated with direct measurement of tendon forces using cadaver forearms. The proposed instrumented set-up will allow the application of controlled forces to the flexor tendons while the resulting gripping forces are measured with force sensitive resistors. Consequently, the true internal tendon forces generated by specific external forces for various handle types and sizes can be found. [Description provided by NIOSH]
