Shoulder kinesthesia after anterior glenohumeral joint dislocation
The Journal of Orthopaedic and Sports Physical Therapy
|January 1, 1990
Summary
Shoulder dislocations significantly impair kinesthesia, affecting movement sensation and accuracy. Rehabilitation should focus on restoring shoulder joint and muscle receptor function to prevent reinjury.
Area of Science:
- Orthopedics
- Sports Medicine
- Physical Therapy
Background:
- Glenohumeral joint dislocations can lead to altered proprioception.
- Understanding kinesthetic deficits is crucial for effective rehabilitation after shoulder injury.
Purpose of the Study:
- To investigate kinesthesia in healthy shoulders versus those with a history of anterior glenohumeral dislocation.
- To assess accuracy of angular reproduction, sensation of movement threshold, and end-range reproduction.
Main Methods:
- Utilized a motor-driven shoulder-wheel apparatus for testing.
- Compared kinesthetic measures in 10 healthy subjects and 8 subjects with unilateral anterior dislocation history.
- Employed analysis of variance and post hoc analysis for statistical significance.
Main Results:
- Significant differences (p < 0.001) in kinesthetic tests between injured and uninjured shoulders.
- Post hoc analysis revealed significant differences (p < 0.02) between involved and uninvolved shoulders.
- No significant differences were found among uninvolved shoulders.
Conclusions:
- Kinesthetic deficits are present after glenohumeral dislocation.
- These deficits may contribute to abnormal neuromuscular coordination and increase reinjury risk.
- Therapeutic activation of shoulder joint and muscle receptors is recommended for rehabilitation.
