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.

Eligibility | Inclusion Criteria: 1. 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. 2. Self-reported decreased performance or feeling fear to perform shoulder movements during sports or daily activities 3. Positive findings on = 1 of the following 5 tests: load and shift test, apprehension, relocation, & surprise tests, Gagey hyperabduction test, sulcus sign, Feagin test 4. Recreational overhead athletes who keep practicing = 4 hours/week in the recent 1 month and with = 1 year overhead sports experience Exclusion Criteria: 1. Full contact sport athletes 2. Severe shoulder instability with > 5 shoulder dislocations history 3. Obvious shoulder bony/labrum lesion in the dominant side warranted for surgery first as decided by the orthopedic surgeon 4. Previous surgery or fracture in the shoulder area on the dominant side within 1 year 5. Voluntary instability (the ability to deliberately dislocate one's shoulder) 6. During acute phase after shoulder dislocation event 7. 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 8. Pregnancy 9. Cancer, neck pain, brain & neurological impairment 10. Ehlers-Danlos syndrome or Marfan syndrome 11. Unable to attend 6 weeks supervised training |

Primary | Shoulder isokinetic muscle strength | Shoulder isokinetic muscle strength will be measured by dynamometer in 3 modes (concentric/concentric, concentric/eccentric, eccentric/concentric) at 3 angular velocities (90°/s, 180°/s, & 240°/s), 1 set of 5 repetitions for each angular velocities. Shoulder isokinetic muscle strength will be normalized by body weight (BW) and described with peak torque/BW (N·m·kg-1). | Change from baseline shoulder isokinetic muscle strength through completion of 12-session intervention, an average of 6 weeks | |
Primary | Shoulder acceleration time, deceleration time, and amortization time | Shoulder acceleration time, deceleration time, and amortization time will be measured by dynamometer in concentric/concentric mode at 3 angular velocities (90°/s, 180°/s, & 240°/s) and will be described with millisecond (ms). | Change from baseline shoulder isokinetic muscle strength through completion of 12-session intervention, an average of 6 weeks | |
Primary | Shoulder proprioception | Shoulder proprioception will be measured by dynamometer in 90° shoulder abduction and 90° elbow flexion position, including active joint position sense and passive joint position sense. The proprioception will be described with degree of error from target position. | Change from baseline shoulder external rotation joint position sense through completion of 12-session intervention, an average of 6 weeks | |
Primary | Seated medicine ball throw distance | Subjects will throw a 2kg soft weighted ball as far forward as possible with dominant arms while sitting with back against a wall and legs bending with feet flat on the floor. Outcomes include average throwing distance and maximal throwing distance (cm). The distances are measured with measure tape. | Change from baseline seated medicine ball throw distance through completion of 12-session intervention, an average of 6 weeks | |
Secondary | Shoulder function | Shoulder function will be measured by the disabilities of the arm, shoulder and hand (DASH) questionnaire, including the disability/symptom section (30 items, scored 1-5) and the optional high performance Sport/Music or Work section (4 items, scored 1-5). A higher score indicates greater disability. | Change from baseline DASH questionnaire through completion of 12-session intervention, an average of 6 weeks | |
Secondary | Visual analogue scale (VAS) of shoulder pain and instability | Shoulder pain and instability will be measured by visual analogue scale (VAS). Subjects need to mark the point that they feel represent their perception of their current state on a 10-cm line. Scores range from 0 (no symptom) to 100 (maximum symptom). | Change from baseline VAS of shoulder pain and instability through completion of 12-session intervention, an average of 6 weeks | |
Secondary | Global rating of change (GRC) | The improvements in a patient's condition will be measured with 15-point self-report GRC scale. Score ranges from -7 (lack of progress) to 7 (maximum of progress). | through completion of 12-session intervention, an average of 6 weeks |
