Self-Managed Music-Guided Exercise Intervention Improved Upper and Lower Extremity Muscle Strength for ICU...

Area of Science:

• Rehabilitation Medicine
• Critical Care Medicine
• Exercise Physiology

Background:

• Intensive care unit (ICU) survivors often experience significant muscle weakness and functional decline.
• Early rehabilitation is crucial for recovery, but adherence can be challenging.
• Novel interventions are needed to support muscle strength recovery post-ICU.

Purpose of the Study:

• To evaluate the effects of a self-managed, music-guided exercise intervention on muscle strength in ICU survivors.
• To compare the efficacy of music-guided exercise against a standard exercise brochure.

Main Methods:

• A two-arm randomized-controlled trial was conducted with ICU survivors post-discharge.
• Participants were assigned to either a music group (self-managed exercises with music) or an active control group (exercise brochure).
• Muscle strength was measured using dynamometers, and data were analyzed with t-tests and Weighted GEE models.

Main Results:

• The music group demonstrated significant improvements in handgrip, plantar flexion, leg extension, elbow flexion, and shoulder adduction strengths.
• Significant post-intervention differences in leg extensor and plantar flexor strengths were observed between the music and control groups.
• Effect sizes ranged from small to moderately large, indicating a meaningful impact of the music intervention.

Conclusions:

• A self-managed, music-guided exercise intervention shows potential for improving muscle strength in ICU survivors.
• This approach may help prevent further physical deterioration following intensive care unit stays.
• Further research is warranted to confirm these preliminary findings in larger trials.
