Finger Flexor Tendon Excursion During Computer Keyboarding

Previously our laboratory demonstrated that a continuous one-hour keyboarding assignment caused acute changes in the ultrasonographic measures of the median nerve.¹ We also attempted to correlate these changes to a variety of contributing factors, such as individual features, as well as certain biomechanical variables. In this study, our objective was to quantify the amount of tendon travel as a function of keyboarding and investigate the effects of tendon travel on the median nerve ultrasonographic measures.
