ABSTRACT
Study design: prospective clinical trial study
Background: People with shoulder impingement syndrome (SIS)
present alterations in the scapular kinematics ‘scapular dyskinesis' when
compared with asymptomatic individuals. Those patients consistently
report disability, especially during overhead activities, which might
hinder activities of daily living and for some sports movements.
Objectives: To investigate if the disability can predict patient's response
to scapular training. Methods: Forty-five patients between 18-45 years
old, their mean age (32.56±2.85) years and their mean body mass index
(BMI) (29±6) kg/m², suffering from subacromial impingement syndrome
assessed by Shoulder Pain and Disability Index (SPADI) before and after
exercise program of scapular muscle training (Cools exercises), serratus
anterior strength (supine punch) and scapular stabilization exercises for
one month. Results: The Area under curve (AUC) showed excellent
results with disability percent 0.94(sensitivity 0.956, specificity 0.156).
Conclusion: disability is a predictor of treatment success in patients
suffering from subacromial impingement syndrome treated with scapular
training.
