The Effect of McConnell Shoulder Taping on EMG Activity and Torque Production of the Shoulder Muscles in Subjects With Anterior Shoulder Instability.

IRB Number: 27050

Institutional Review Board
Hospital for Special Surgery


The safety of study participants is our top priority. The trial is approved and periodically reviewed by an Institutional Review Board (IRB), which includes doctors, administrators, ethicists, and members of the general public. The safety of clinical trials is reviewed by the U.S. Food and Drug Administration.

Before enrolling in a clinical trial, the investigator will explain the purpose of the trial, its expected benefits, any possible risks or side effects, and what your role will be. This is the time to ask questions! If you want to join the trial, you must sign the informed consent documents. You can leave a clinical trial at any time without penalty.

Summary

24 subjects with anterior shoulder instability will undergo one testing session of approximately 1 hour 15 minutes with no follow-up session.  Subjects will have the EMG activity of  10 shoulder girdle muscles tested using a combination of fine wire and surface electrodes during three isokinetic movement patterns (Scaption, IR/ER @ 45 and 90 degrees abduction) over three conditions: baseline (no intervention), McConnell shoulder taping for anterior shoulder instability and sham taping (placebo).  Outcome variables include EMG amplitude and onset time and torque production over the three conditions.  This study is designed to determine the efficacy of using shoulder taping for the treatment of non-surgical anterior shoulder instability.

Inclusion/Exclusion Criteria

Inclusion criteria:

  • A positive finding on any of the following anterior shoulder instability clinical tests: load and shift, fulcrum, anterior drawer test; or the apprehension and relocation tests;
  • A negative sulcus sign for multidirectional instability;
  • A negative clinical or radiologic exam for a Bankart lesion or a rotator cuff tear;
  • A VAS pain score of 3 or less upon shoulder ROM testing;
  • Passive range of motion (PROM) of the shoulder to be tested within 10% of the unaffected side;
  • Ages 18-40 years of age.
     

Exclusion Criteria:

  • Previous shoulder anterior stabilization surgery
  • Evidence of existing rotator cuff tear or labral tears (based on the physician examination or related diagnostic testing)

    Allergies to metal
  • < 18 years of age
  • > 40 years of age
  • VAS pain scale > 3
  • Subjects who are currently being treated by any of the investigators
  • Subjects who have experience with shoulder taping in the past
