ABSTRACT

This relation was used by Armstrong and Chaffin (1979) to evaluate the effects of wrist posture and gender-related wrist anthropometry on tendon stresses, based on wrist radii measurements made on cadavers (Armstrong and Chaffin, 1978). According to the model, wrist size affects the normal forces acting between the tendons and surrounding tissues (Figure 10.3).

Figure 10.2 The tendons of the extrinsic finger flexor muscles can be conceptualised as belts wrapping around a pulley. The tension in the tendon, and F are different because of frictional forces acting on
