Le résumé fourni par la source

Objective: Blackburn exercises and Rhythmic stabilization technique is effective to stabilize and control scapular movements. The study compares the effects of Blackburn exercises and Rhythmic Stabilization on scapular dyskinesis in guitarists. Methods: A total of 40 acoustic guitarists of both genders with scapular dyskinesia, aged 18-35 years, with an experience of minimum 2 years playing for at least 20 hours/week were included in the study. The subjects were allocated in two groups- Group A and Group B. Both the groups were given Pectoralis minor stretching. Along with that, the guitarists in Group A were given Blackburn exercises while in the Group B were given Rhythmic Stabilization 3 times/week for 4 consecutive weeks. Scapular dyskinesis was measured by Lateral Scapular Slide Test, the tightness in the pectoral muscles with Pectoralis Minor Muscle Length test, functional assessment was done by Shoulder Pain and Disability Index and pain with Algometer. Outcome measures used pre intervention were remeasured and compared in two groups using SPSS 21.0 version. Findings: Homogeneity was maintained with regards to gender and age in both the groups. The result of the study for both the groups post intervention showed a significant improvement in all the outcome measures with p value <0.05. Blackburn exercise and Rhythmic Stabilization were advantageous individually for all the outcome measure suggestive of improvement on scapular dyskinesia; however, when comparing the post-test results, Blackburn's intervention outperformed Rhythmic stabilization by a substantial margin (p value <0.005) for scapular dyskinesia in guitarists. Thereby concluding that both Blackburn exercises and Rhythmic Stabilization is effective in improving scapular dyskinesis in guitarists, with Blackburn exercises being more effective than Rhythmic Stabilization. Novelty: This work has established the efficacy of Backburn exercises over the age-old technique of Proprioceptive Neuromuscular Facilitation as a new approach for shoulder dyskinesia treatment.
