Effects of Inspiratory Muscle Training on the Functional Gait Performance of Individuals After Stroke
The most commonly observed sequel after stroke is muscle weakness, which can also be identified in respiratory muscles, in the acute and chronic phases, and may compromise the lung function of these individuals. Studies have shown that lower Pimax values are found in non-community ambulators, and gait velocity has been reported as an important indicator of functionality after stroke, with higher gait velocity values associated with greater community participation and better quality of life.
This study will test the hypothesis that training of the inspiratory muscles is effective in improving strength and endurance of the inspiratory muscles and functionality, including speed of gait, functional gait perfomarnce, activities of daily living and quality of life with stroke subjects.
For this clinical trial, people after stroke will be randomly allocated into either experimental or control/sham groups. The experimental group will undertake training of the inspiratory muscles with the Power Breath Medical Classic device regulated at 50% of the subjects' maximal inspiratory pressure values, five times/week over six weeks, twice a day for 15 minutes, totaling 30 minutes/day. The control group will undertake the same protocol, but the participants will receive the devices with a minimal load, wich corresponds to 1cmH2O. Both groups will participate in the rehabilitation program for 6 weeks. At baseline and post intervention, after the cessation of the interventions, researchers blinded to group allocations will collect the following outcome measures: maximal respiratory pressures, respiratory muscle endurance, functional gait performance, activities of daily living and quality of life. After 12 weeks will collect again maximal inspiratory pressures and functional gait performance.

The most commonly observed sequel after stroke is muscle weakness, which can also be identified in respiratory muscles, in the acute and chronic phases, and may compromise the lung function of these individuals. Studies have shown that lower Pimax values are found in non-community ambulators, and gait velocity has been reported as an important indicator of functionality after stroke, with higher gait velocity values associated with greater community participation and better Quality of life.
Aim: This study will test the hypothesis that training of the inspiratory muscles is effective in improving strength and endurance of the inspiratory muscles and functional gait perfomarnce, activities of daily living and quality of life with stroke subjects.
Design: For this prospective, triple-blinded, randomized clinical trial, people after stroke will be randomly allocated into either experimental or control/sham groups. The experimental group will undertake training of the inspiratory muscles with the PowerBreath Medic Plus regulated at 50% of the subjects' maximal inspiratory pressure (MIP) values, five times/week over six weeks during 30 minutes/day. The control group will undertake the same protocol, but the participants will receive the threshold devices with minimal resistance valves. At baseline and post intervention after the cessation of the interventions, researchers blinded to group allocations will collect all outcome measures. After 12 weeks will collect again maximal inspiratory pressures and functional gait performance.
Study outcomes: Primary outcomes will be functional gait perfomarnce. Secondary outcomes will include inspiratory endurance, activities of daily living and quality of life.

Experimental: IMT will include training of the inspiratory muscles five times per week over six weeks, divided into two fiftten-minute sessions of inspiratory training totaling 30 minutes of training. Thresholds regulated at 50% of the subjects' maximal inspiratory pressure values, the load being increased weekly. Associated with the IMT, subjects will participate in the rehabilitation program, when they will perform 7 sessions of physiotherapy per week, totaling 42 sessions, as well as 180 minutes per week of aerobic exercise, for six weeks. Sham Group: This group will underwent exactly the same protocol but the participants will receive the threshold devices with the minimum resistance of the spring, which will be also concealed. The control group will also participate in the rehabilitation program and undergo the same procedures, except for the load adjustments. |
