Overview

Randomized trial compares breathing-integrated and thoracic-scapular stabilization exercises on muscle strength and posture in individuals with shoulder dysfunction, showing improvements for both.

Key Points

  • This study aims to compare the effects of two exercise interventions on muscle strength and postural alignment in individuals with shoulder dysfunction.
  • Randomized controlled trial with 32 adults having shoulder dysfunction characterized by scapular internal rotation.
  • Participants were divided into two groups: one performing breathing-integrated scapular stabilization exercises, and the other thoracic–scapular stabilization exercises, for 4 weeks.
  • Assessments included muscle strength, pectoralis minor length, and shoulder sagittal angle, analyzed with two-way repeated-measures ANOVA.
  • Both exercise interventions resulted in significant improvements in muscle strength, pectoralis minor length, and shoulder sagittal angle (p < 0.025).
  • Upper trapezius strength did not show significant changes after the intervention.
  • No significant group × time interaction effects were observed, indicating no superiority of one intervention over the other.
