OBJECTIVE: To compare the effects of inspiratory resistance training and
isocapnic hyperpnoea vs incentive spirometry (placebo) on respiratory function,
voice, thorax mobility and quality of life in individuals with tetraplegia.
DESIGN: Randomized controlled trial. METHODS: A total of 24 individuals
with traumatic, complete tetraplegia (C5-C8, American Spinal Injury Association
(ASIA) Impairment Scale; AIS A) were randomly assigned to 1 of 3 groups. They
completed 32 supervised training sessions over a period of 8 weeks. Before and
after the training period, the following tests were performed: body
plethysmography, inspiratory and expiratory muscle strength, subjective breathing
parameters using a visual analogue scale, voice measurements, thorax mobility and
quality of life. Cohen's effect sizes and Kruskal-Wallis tests for differences
between pre- and post-training values were calculated. RESULTS: Compared with
placebo training, inspiratory resistance training showed high effect sizes for
inspiratory muscle strength (d = 1.13), the subjective ability "to blow one's
nose" (d = 0.97) and the physical component of quality of life (d = 0.82).
Isocapnic hyperpnoea compared with placebo showed a high effect size for
breathlessness during exercise (d = 0.81). We found a significant effect of
inspiratory resistance training vs placebo (p = 0.016) and vs isocapnic
hyperpnoea (p = 0.012) for inspiratory muscle strength. CONCLUSION: In
individuals with motor and sensory complete tetraplegia during the first year
post-injury, inspiratory resistance training is more advantageous than isocapnic
hyperpnoea, performed 4 times a week for 10 min.
