The Effects of Upper-Extremity Plyometric Combined Strength Training in Overhead Athletes With Shoulder Instability
Taiwan64 participantsStarted 2023-05-20
Plain-language summary
The purpose of this randomized controlled trial is to investigate the additional effects of upper extremity plyometric training versus strength training alone in recreational overhead athletes with shoulder instability. The investigators hypothesis that compared to strengthening training alone, plyometric training combined with strengthening training will significantly improve shoulder isokinetic strength, proprioception, scapular kinematics, symptoms of shoulder instability, and shoulder function.

Inclusion criteria
✓. Have experience of at least 1 of the following symptoms of shoulder instability during upper extremity movement: (a) pain, clicking, a sense of the shoulder coming apart, (b) dead-arm syndrome, or (c) subluxation of the joint.
✓. Self-reported decreased performance or feeling fear to perform shoulder movements during sports or daily activities
✓. Positive findings on ≥ 1 of the following 5 tests: load and shift test, apprehension, relocation, \& surprise tests, Gagey hyperabduction test, sulcus sign, Feagin test
✓. Recreational overhead athletes who keep practicing ≥ 4 hours/week in the recent 1 month and with ≥ 1 year overhead sports experience
Exclusion criteria
✕. Full contact sport athletes
✕. Severe shoulder instability with \> 5 shoulder dislocations history
✕. Obvious shoulder bony/labrum lesion in the dominant side warranted for surgery first as decided by the orthopedic surgeon
✕. Previous surgery or fracture in the shoulder area on the dominant side within 1 year
What they're measuring
1
Shoulder isokinetic muscle strength
Timeframe: Change from baseline shoulder isokinetic muscle strength through completion of 12-session intervention, an average of 6 weeks
2
Shoulder acceleration time, deceleration time, and amortization time
Timeframe: Change from baseline shoulder isokinetic muscle strength through completion of 12-session intervention, an average of 6 weeks
3
Shoulder proprioception
Timeframe: Change from baseline shoulder external rotation joint position sense through completion of 12-session intervention, an average of 6 weeks
4
Seated medicine ball throw distance
Timeframe: Change from baseline seated medicine ball throw distance through completion of 12-session intervention, an average of 6 weeks
✕. Voluntary instability (the ability to deliberately dislocate one's shoulder)
✕. During acute phase after shoulder dislocation event
✕. Not suitable to start plyometric training yet: Shoulder muscle weakness (manual muscle test \<3) or range of motion limitation (\<90 abduction, \<70 external rotation) in the dominant side
