Design: Randomized controlled study of six-week duration. Subjects: Forty patients with multiple sclerosis (age 39.2 ± 7 years; Kurtzke Expanded Disability Status Scale scores: 4.51 ± 1.55) randomly divided into two groups. Methods: The training group followed a six-week home training programme designed to strengthen accessory respiratory muscles. Controls performed no exercises. All subjects submitted to baseline and post-training tests of spirometry, respiratory muscle strength and 6-minute walking. They were also assessed with pulmonary dysfunction and exertion fatigue indices. Results: Spirometry revealed clear improvement in forced expiratory volume in 1 second (FEV 1) (+13%, P = 0.003) resulting in higher FEV1/FVC (forced vital capacity) (+8.5%, P = 0.03). Maximal inspiratory pressure (P Imax) increased by +7.1% but not significantly. Maximal expiratory pressure (P Emax) and FVC were significantly higher (by +7.1%, P = 0.0066 and +4.8%, P = 0.036 respectively) with respect to baseline measures. Pulmonary dysfunction was reduced (—9%, P = 0.002) while 6-minute walking distance was longer (+16%, P = 0.029) at equal exertion fatigue level. Conclusions: The programme improved most pulmonary performance measures and had clinical significance. Its sustained application may prevent respiratory complications frequently observed in the later stages of multiple sclerosis.
