• Description:
  The relationship of flexed and extended wrist forces to wrist size, hand force, and hand position was examined based on biomechanical arguments. The arguments characterize the extrinsic finger flexor tendons inside the carpal tunnel as a frictionless pulley belt mechanism. Synovial membranes surrounding the extrinsic finger flexor tendons are compressed during forceful exertions with the wrist flexed or extended. The authors propose that the biomechanical arguments support the conclusions of other investigations that exertions with certain hand and wrist positions aggravate, precipitate, or cause occupational carpal tunnel syndrome and suggest that male and female wrist size partially explains the prevailing differences of carpal tunnel syndrome in male and female populations.
