Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

The objective of this study is to investigate i) the effect of 3 weeks IMT to adults post-stroke to maximal inspiratory pressure (MIP) and ii) the effects of 3 weeks IMT to the degree of dependency in activities of daily living, endurance in gait, fatigue, voice volume, phonation endurance, and expiratory function.

Methods/Design: Randomised controlled trial (RCT) comparing IMT to conventional neurorehabilitation (usual practise). 80 patients, with reduced maximal inspiration pressure (MIP) hospitalized at a specialized neurorehabilitation hospital in Denmark will be included.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

Background: Stroke results in varying disabilities physical, cognitive, emotional and/or social both in short term and long term. Motor impairments are significantly persistent consequences post-stroke among these are decreased respiratory muscle function, decreased ability to expand thorax and postural dysfunction. These deficits influence the patient's ability in daily activities, fatigue, endurance and quality of life. Inspiratory muscle training (IMT) is training to improve the strength and endurance of diaphragm and the external intercostal muscles. The objective of this study is to investigate i) the effect of 3 weeks IMT to adults post-stroke to maximal inspiratory pressure (MIP) and ii) the effects of 3 weeks IMT to the degree of dependency in activities of daily living, endurance in gait, fatigue, voice volume, phonation endurance, and expiratory function.

Methods/Design: Randomised controlled trial (RCT) comparing IMT to conventional neurorehabilitation (usual practise). 80 patients, with reduced maximal inspiration pressure (MIP) hospitalized at a specialized neurorehabilitation hospital in Denmark will be included. The intervention group will add-on IMT sessions exercising at 30 % of MIP. Patients in the intervention group perform 2 sessions a day (One session of IMT with IMT threshold flute consists of 2 times 15 inspirations in normal breathing rhythm (5-10 min)), 7 days a week for 3 weeks. Training can be with or without supervision of physiotherapist.

Intervention group

* 2 x IMT (5-10 min) 2 times a day 7 days a week for 3 weeks with or without supervision
* Log-book
* Conventional neurorehabilitation

Group Type EXPERIMENTAL

Inspiratory muscle training (IMT)

Intervention Type OTHER

IMT and conventional neurorehabilitation - treatment as usual. The intervention group will add-on IMT sessions exercising at 30 % of MIP. MIP is measured by instructing the patient to perform five forceful inspirations against an occluded mouthpiece (Power Breath). The best score is multiplied by 0.3 to determine the resistance. IMT is performed with IMT Threshold flute with the calculated resistance. During the measurement with Power Breath the patient sits straight up and uses nose clip. The patient can receive help to hold the Power Breath if necessary.

One session of IMT with IMT threshold flute consists of 2 times 15 inspirations in normal breathing rhythm (5-10 min). Patients in the intervention group perform 2 sessions a day (morning and evening), training is performed prior to a meal, 7 days a week for 3 weeks.
