Additional Effect of Intrapulmonary Percussive Ventilation (IPV) on Respiration in People With Multiple Sclerosis (MS).

National Multiple Sclerosis Center5 enrolled

Overview

This study aims to investigate whether intrapulmonary percussive ventilation (IPV) in combination with active breathing exercises using the flow-based incentive spirometer (Inspirix) has a positive effect on the respiratory values in people with multiple sclerosis (MS).

The primary research question includes "what is the additional effect of intensive IPV treatment in combination with active breathing exercises on respiratory power (Peak Expiratory Flow, PEF) in people with MS?". In a single-center randomized clinical trial, 96 people with MS-related respiratory problems will be allocated to either the intervention group (IPV + active breathing training) or the control group (active breathing training only). Interventions will be provided by trained speech- and language therapists, in combination with a multidisciplinary rehabilitation programme of 3 weeks. Pre- en posttraining assessment includes measures of respiration, speech and fatigue.

Intrapulmonary percussive ventilation (IPV)DEVICE

IPV is a well-tolerated method to pump air jets into the lungs via a mouth mask at frequencies of 100-400 pulses per minute. Each IPV session lasts 15 minutes, whereby the person with MS is firstly administered with a mask for 3 minutes at a high frequency (250 to 400 cycles per minute) and then 12 minutes with a low frequency (75 to 150 cycles per minute). The pressure (1.1 - 1.4 bar) is adjusted so that it is comfortable for every participant, yet there is the maximum possible expansion of the thorax. The sessions are given by speech therapists who are familiar with IPV. The IPV treatment will be provided 5 days a week, during 3 or 4 weeks.

Active breathing trainingBEHAVIORAL

The active breathing exercises are based on the flow-based incentive spirometer (Inspirix). The Inspirix is a device consisting of a tube with a ball. A plastic tube is connected to the device with a mouthpiece in which the person with MS will has to breathe in and out. The device is equipped with a control button to build up the resistance (number of cc / sec). The aim is to train the inspiratory and expiratory volume as well as the inspiratory and expiratory exhalation force. These exercises are offered 5 times a week in groups under the supervision of an experienced speech therapist, during 3 or 4 weeks.
