The Optimal Treatment Duration for Inspiratory Muscle Strengthening Exercises in Stroke Patients: A Double-blind Randomised Controlled Trial
The Optimal Treatment Duration for Inspiratory Muscle Strengthening Exercises in Stroke Patients: A Double-blind Randomised Controlled Trial
The first aim of this study is if there is any difference between 4 or 8 weeks of inspiratory muscle training ( IMT ) exercises groups and control groups in stroke survivors. The secondary aims of this study is if there is any difference in walking capacity (in 8th, 12th, 24th weeks) and pulmonary complications (pneumonia incidences) in long term follow-ups (6 months) in these aforementioned groups
Stroke is one of the leading causes of death and disability. It is not only because of loss of extremity motions but also loss of inspiratory muscle strength. In this study we aimed to determine the optimum duration for inspiratory muscle training exercises for stroke survivors since there is not enough data about it in the literature.
The study will include at least 54 patients in total and 18 in each groups ( two intervention and one control) . The patients will be evaluated for angina, chronic obstructive pulmonary disease, congestive heart disease; in these conditions the patients will be excluded from the study. Also in first examinations we will evaluate the maximal inspiratory pressure (MIP) of patients, of them the ones with MIP measurements above 80 mmH2O will also be excluded since it is the expected value in normal people.
After admission and randomizing the patients, baseline measurements of MIP, 6-minutes walking test will be done. In intervention groups the patients will get 30 minutes of inspiratory muscle training exercises ( 15 minutes of two session each day) with threshold IMT device every weekday. And in control group, the patients will get sham intervention for 8 weeks. The MIP and 6-minutes walking test will be done in 8th,12th and 24th weeks. And also in 24th week we will record the pneumonia incidence if occured.
