The Impact of Tennis and Golfer’s Elbow on Shoulder External Rotators and Abductors Peak Torque

Context:Upper limb activities require a repetitive movement of the shoulder external rotator and abductor muscles. The malfunction of the proximal part of the upper limb kinetic chain tends to change the mechanics of the distal part and increase the risk of injuries.Objectives:To compare the normalized eccentric peak torque (NEPT) of the shoulder external rotator and abductor muscles among healthy athletes and those with tennis elbow and golfer’s elbow.Design:An experimental cross-sectional study.Setting:Isokinetic laboratory, Faculty of Physical Therapy, Cairo University.Participants:Thirty male athletes participated voluntarily in this study.Intervention:Participants were distributed into three groups; healthy group, tennis elbow group, and golfer’s elbow group.Main Outcome Measure(s):Normalized eccentric peak torque (NEPT) of shoulder abductors and external rotators. The Biodex Isokinetic Dynamometer was used to measure the variables of interest.Results:there was a significant increase in the NEPT of s...
