Respiratory Muscle Training in Acquired Brain Injury Patients.

Summary

Background: Respiratory health problems are one of the main causes of morbidity and mortality in adult people with acquired brain injury (ABI). The influence of respiratory muscle training has not yet been studied in this population group. The objective of the study was to evaluate and compare the efficacy of two protocols with respiratory muscle training, inspiratory muscle training vs expiratory muscle training, to improve respiratory strength and pulmonary function in adults with CP.

Methods: The study is a controlled, randomised, double-blind trial and with allocation concealment. 26 ABI patients will be recruited and randomly distributed in the inspiratory muscle training group (IMT) and the expiratory muscle training group (EMT). Over an 8-week period an IMT or EMT protocol was followed 5 days/week, 5 series of 1-minute with 1-minute rest between them. IMT trained with a load of 50% of the maximum inspiratory pressure (MIP) and EMT with 50% of the maximum expiratory pressure (MEP). Respiratory strength and pulmonary function were evaluated.

Interventions

DEVICE

Inspiratory muscle training

Respiratory training, performed through IMT, was carried out with a pressure threshold device (Treshold IMT, Philips-Respironics, Pittsburg, PA, USA). Threshold IMT offers a constant and specific pressure for strength and endurance training of the respiratory muscles, regardless of the strength or speed with which patient breathes. A flow-independent one-way valve ensures constant resistance and allows you to specifically adjust workload (in cmH2O). The training must be supervised by a healthcare professional. During the inspiration, a spring-loaded valve resists to stimulate the training of the respiratory muscles. Before training began, the participants and primary caregivers completed one-session familiarization with a specialist to know the operation of the device. Adult people with acquired brain injury carried out the training program for 8 weeks, 1 session every day, 5 days a week. The participants performed 5 series of 1 minute with 1-minute rest between them.
