• Description:
  Risk factors for tendon disorders of the hand may include the force level, number of repetitions, hand posture, and hand velocity. To differentiate between these factors and better understand the injury mechanisms, it is important to understand how these external factors affect internal tendon loading. The relationship between the force at the fingertip and the in vivo force in a flexor tendon while tapping on a keyswitch has been reported previously (1). In addition to the force level, the force rate that a tendon experiences may influence the damage mechanism since loading rate influences tissue strain and fatigue properties. The goal of this investigation was to calculate the mean and maximum in vivo force rates in the flexor digitorum superficialis (FDS) tendon while tapping, compare the values during the loading (increasing force) and unloading (decreasing force) parts of the motion, and compute the corresponding force rates at the fingertip.
