Effect of singing on respiratory function, voice, and mood after quadriplegia: a randomized controlled trial.

摘要: Abstract Objective To explore the effects of singing training on respiratory function, voice, mood, and quality life for people with quadriplegia. Design Randomized controlled trial. Setting Large, university-affiliated public hospital, Victoria, Australia. Participants (N=24) chronic quadriplegia (C4-8, American Spinal Injury Association grades A B). Interventions The experimental group (n=13) received 3 times weekly 12 weeks. control (n=11) music appreciation relaxation Assessments were conducted pre, mid-, immediately post-, 6-months postintervention. Main Outcome Measures Standard function testing, surface electromyographic activity from accessory muscles, sound pressure levels during vocal tasks, assessments voice (Perceptual Voice Profile, Multidimensional Profile), Handicap Index, Profile Mood States, Assessment Quality Life instruments. Results increased projected speech intensity ( P =.028) maximum phonation length =.007) significantly more than group. Trends improvements in muscle strength, recruitment also evident These limited by small sample sizes large intersubject variability. Both groups demonstrated an improvement mood =.002), which was maintained after 6 months =.017). Conclusions Group therapy can have a positive effect not only physical outcomes, but improve energy, social participation, at-risk population, such as those Specific augment these general improving intensity.
