Brief Summary

The aim of this study is to investigate the effects of shoulder eccentric exercise training on shoulder mobility, rotator cuff strength, pain and dysfunction, scapular kinematics and muscle activation in symptomatic overhead athletes with posterior shoulder tightness.

Conditions

Posterior Shoulder Tightness

Keywords

Posterior shoulder tightness; Eccentric exercise; Shoulder impingement syndrome

Outcome Measures

Primary Outcomes (5)

• Shoulder range of motion (measured with goniometer)

  Shoulder external rotation, internal rotation, horizontal adduction range of motion in shoulder flexion 90 degrees

  4 weeks

• Rotator cuff functional strength ratio (Pro 4, Biodex Medical Systems, Inc., Shirley, NY, USA)

  Eccentric strength of shoulder external rotator and concentric strength of shoulder internal rotator are measured with isokinetic

  4 weeks

• Shoulder pain

  Pain is measured with Visual Analogue scale (VAS) Score range from 0 to 10. Scoring of 0 represents no pain and scoring of 10 represents pain as bad as it could possibly be.

  4 weeks

• Shoulder function

  Shoulder function is measured with Disability of the Arm, Shoulder and Hand questionnaire (DASH) Score range from 0 to 100. The higher of the score, the more disability.

  4 weeks

• Shoulder endurance test

  Participants will be instructed to execute a shoulder endurance test with the theraband®. Participants are asked to place their tested arm in a shoulder forward flexion 90-degree position, holding a 1-m long theraband® fixed at shoulder height on a graduated stick. Then, they are asked to pull the theraband® from the starting position to a 90-90 ending position at an alternated cadence given by a metronome. Males were asked to pull a green theraband® (2.1 kg) and females a red theraband ® (1.7 kg).

  4 weeks

Secondary Outcomes (2)

• Electromagnetic tracking system (Liberty electromagnetic tracking system, Polhemus , Colchester, VT,)

  4 weeks

• Surface electromyography (TeleMyo 2400T G2, Noraxon USA Inc., Scottsdale, AZ, USA)

  4 weeks
