The effect of singing training on voice quality for people with quadriplegia.

Objectives: Despite anecdotal reports of voice impairment in quadriplegia, the exact nature of these impairments is not well described in the literature. This article details objective and subjective voice assessments for people with quadriplegia at baseline and after a respiratory-targeted singing intervention.

Study Design: Randomized controlled trial.

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

Objective: To explore the effects of singing training on respiratory function, voice, mood, and quality of life for people with quadriplegia.

Design: Randomized controlled trial.

Setting: Large, university-affiliated public hospital, Victoria, Australia.

Assessment of breathing patterns and respiratory muscle recruitment during singing and speech in quadriplegia.

Objectives: To explore how respiratory impairment after cervical spinal cord injury affects vocal function, and to explore muscle recruitment strategies used during vocal tasks after quadriplegia. It was hypothesized that to achieve the increased respiratory support required for singing and loud speech, people with quadriplegia use different patterns of muscle recruitment and control strategies compared with control subjects without spinal cord injury.

Design: Matched, parallel-group design.
