Comprehensive corrective exercise program improves alignment, muscle activation and movement pattern of men with...

Area of Science:

• Kinesiology and Exercise Science
• Musculoskeletal Rehabilitation
• Biomechanics

Background:

• Upper crossed syndrome (UCS) is characterized by altered muscle activation, scapular movement patterns, and upper quarter alignment, potentially leading to cervicothoracic and glenohumeral joint dysfunction.
• Effective interventions are needed to address the neuromuscular and biomechanical deficits associated with UCS.

Purpose of the Study:

• To evaluate the efficacy of a comprehensive corrective exercise program (CCEP) on alignment, muscle activation, and movement patterns in men diagnosed with UCS.
• To assess the impact of a subsequent four-week detraining period on these outcomes.

Main Methods:

• A randomized controlled trial involving 24 men with UCS was conducted.
• The intervention group underwent an 8-week CCEP, followed by 4 weeks of detraining.
• The control group maintained normal daily activities.
• Measurements included electromyography, scapular dyskinesis tests, and angular assessments of the head, shoulder, and thoracic spine at baseline, post-intervention, and follow-up.

Main Results:

• Significant group-by-time interactions and within-group improvements were observed across all measured outcomes from pre-test to post-test and follow-up.
• The CCEP group demonstrated significant improvements compared to the control group in three key outcomes at both post-test and follow-up.
• These positive changes indicate a successful correction of muscle activation imbalances and improved biomechanical function.

Conclusions:

• The CCEP is a feasible and effective intervention for individuals with upper crossed syndrome.
• The program successfully enhances muscle activation balance, movement patterns, and postural alignment.
• The observed improvements were sustained after a four-week detraining period, suggesting long-term neuromuscular adaptations.
