title: [Effectiveness of epicondylitis bandages from the biomechanical viewpoint--an experimental study].
abstract: OBJECTIVE
  During extension of the elbow joint (test measurement) and extension of the wrist (control measurement), maximal bandage pressure is desired on the extensor group of the forearm, especially of the M. extensor carpl radialis brevis (ECRB). Do the various commercial epicondylitis bandages produce a mechanical effect on the extensor group of the forearm and how do the maximal pressures of these bandages behave in direct comparison? Are the pressures produced clinically relevant?
  
  
  METHODS
  Eleven different epicondylitis bandage constructions were examined for their biomechanical effects. The exerted pressure was measured continously during the above-mentioned movements. A fist-closing strength of ca. 30 N was maintained for the necessary pre-stressing of the forearm muscles.
  
  
  RESULTS
  Strap-type bandages were the only bandages to produce adequately high pressures. Bands applied at pressures which approach those of the straps led to obstruction in bloodflow. Stocking designs showed no effect in respect to our study.
  
  
  CONCLUSIONS
  Bandages which apply pressure to relieve the tendon insertion of the extensor muscles must, from a technical standpoint, be of a strap construction in order to build up adequate pressures to be effective.
