Abstract

IntroductionMuscular dystrophies (MD) cause muscle weakness, affecting motor and respiratory functions. Aquatic activities maintain strength and ventilatory function and may require immersion expiration control.Objectives(1) To describe the evolution of timed immersion expiration in patients with MD in one-year follow-up. (2) to describe motor and respiratory outcomes in one-year follow-up. (3) to investigate possible relationships between timed immersion expiration and age, motor and respiratory functions.MethodFifty-seven patients with MD (12–35 years, Vignos scale 2–8) were evaluated twice, with one-year interval. Immersion expiration control was timed with a chronometer. Motor function was assessed by Motor Function Measure. The respiratory function was evaluated by spirometry. Analysis of variance compared assessments and Pearson tests investigated relationships between variables and age.ResultsMotor and respiratory functions decreased (p < 0.001) but timed immersion expiration was maintained. Timed immersion expiration was not correlated to motor and respiratory functions.ConclusionAs patients maintained timed immersion expiration in the one-year follow-up, aquatic therapy might be a facilitator for people with MD.

As patients maintained timed immersion expiration in the one-year follow-up, aquatic therapy might be a facilitator for people with MD
Timed immersion expiration outcomes No significant differences between LGMD and Duchenne muscular dystrophy (DMD) groups were found in timed immersion mouth expiration (TIME) and timed immersion nose expiration (TINE) assessments (TIME: F1,55 = 2.61; p = 0.112 and TINE: F1,55 = 2.24; p = 0.140)

Summary

Introduction

Muscular dystrophies (MD) cause muscle weakness, affecting motor and respiratory functions. Muscular dystrophies (MD) involve a group of disorders characterized by progressive motor and respiratory functions loss [1,2,3]. Decreased joint mobility and range of motion occur due to muscle weakness, which impacts on static and dynamic postural balance control [4]. The respiratory muscles weakness leads to secondary changes such as atelectasis, decreased lung compliance, ineffective cough and repeated infections [6,7,8]. Patients with MD, mainly Duchenne muscular dystrophy (DMD), develop a restrictive respiratory pattern [8, 9] due to the reduction of. Aquatic exercises are beneficial in the management of musculoskeletal, neurologic and cardiopulmonary problems, which are common in patients with MD [15]
