Brief Summary

A randomized controlled trial will be conducted to examine the effectiveness of a traditional home exercise program versus 2 kinetic chain home exercise programs on treatment outcome of overhead athletes with shoulder impingement syndrome. Primary outcome measures are reduction of pain and disability, and improvement in functionality and sports performance. Secondary outcome measures are strength, mobility, flexibility and functional performance.

Outcome Measures

Primary Outcomes (3)

• Changes in Shoulder Pain And Disability Index (SPADI) score

  Patients will fill in the SPADI questionnaire to evaluate shoulder pain and function. The SPADI is a valid, reliable and frequently used questionnaire for shoulder pain patients consisting of 13 items divided in 2 subscales: pain (5 items) and disability (8 items). Each item was scored on a 10-point numeric rating scale. Total and subscale scores were summed and transformed to a score out of 100 (%) were a higher score indicates a higher level of pain and/or disability

  At baseline and within one week after the 6-weeks training program

• Changes in Western Ontario Shoulder Stability index (WOSI) score

  The WOSI is a patient-evaluated disease-specific quality of life scoring questionnaire that has been developed for shoulder instability patients. This 21-item questionnaire consists of 4 subscales: physical symptoms (10 items), sport/recreation/work (4 items), lifestyle (4 items), and emotions (3 items). Each item was scored on a 100-mm visual analogue scale. Total and subscale scores were summed and transformed to a score out of 100 (%) where a higher score indicates more limitations in shoulder related quality of life

  At baseline and within one week after the 6-weeks training program

• Subjective perception of shoulder improvement

  A Global Rating of Change (GROC) scale was used to quantify patient-perceived improvement of overall shoulder function after 6 weeks treatment as "improved", "unchanged" or "worse". In case they improved or got worse, the amount of change was reflected on a 5-point scale: very little change, little change, some change, a large change, a very large change. An "unchanged" condition scored 0, "improved" between 1 and 5, and "worse" between -1 and -5 points. amount of change was scored on a 5-point scale (very little change, little change, some change, a large change, a very large change)

  6-weeks training program

Secondary Outcomes (6)

• Changes in shoulder muscle isokinetic strength (Biodex system 4)

  at baseline and within one week after the 6-weeks training program

• Changes in shoulder scapular isokinetic strength

  at baseline and within one week after the 6-weeks training program

• Changes in scapular dyskinesis

  at baseline and within one week after the 6-weeks training program

• Changes in functional tests for the upper limb measured with the Y Balance Test

  at baseline and within one week after the 6-weeks training program

• Return To Play (RTP)

  up to one week after the 6-weeks training program

Study Arms (3)

Traditional training

ACTIVE COMPARATOR

A home exercise program consisting of rotator cuff and scapular muscle training will be performed during 6 weeks (4 sessions/week). To monitor progress and control load progression, a physical therapist will visit the subject every week.

Other: Traditional training

Separate kinetic chain training

EXPERIMENTAL

A home exercise program consisting of traditional training exercises as well as separate exercises focusing on core and lower limb training will be performed during 6 weeks (4 sessions/week). To monitor progress and control load progression, a physical therapist will visit the subject every week.

Other: Separate kinetic chain training

Integrated kinetic chain training

EXPERIMENTAL

A home exercise program consisting of traditional training exercises while integrating core and lower limb training will be performed during 6 weeks (4 sessions/week). To monitor progress and control load progression, a physical therapist will visit the subject every week.

Other: Integrated kinetic chain training
