NCT04686019

Brief Summary

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.

Outcome Measures

Primary Outcomes (1)

  • Maximal inspiratory pressure (MIP)

    Change of MIP assess with the Power Breath. This is an objective measurement to describe the inspiratory capacity. Age specific

    Assessed 0-4 days before intervention, 0-4 days after ended intervention assessment and 3 months after ended intervention

Secondary Outcomes (5)

  • Functional Independence Measure (FIM) - both total score ( range from 18 to 126, with higher scores indicating more independence) and motor sub score (max 91)

    Assessed 0-4 days before intervention, 0-4 days after ended intervention assessment and 3 months after ended intervention

  • Fatigue Severity Scale (FSS)

    Assessed 0-4 days before intervention, 0-4 days after ended intervention assessment and 3 months after ended intervention

  • 6-minutes walking test

    Assessed 0-4 days before intervention, 0-4 days after ended intervention assessment and 3 months after ended intervention

  • Voice volume

    Assessed 0-4 days before intervention, 0-4 days after ended intervention assessment and 3 months after ended intervention

  • Expiratory function

    Assessed 0-4 days before intervention, 0-4 days after ended intervention assessment and 3 months after ended intervention

Study Arms (2)

Intervention group

EXPERIMENTAL

* 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

Other: Inspiratory muscle training (IMT)

Control group

ACTIVE COMPARATOR

Conventional neurorehabilitation

Other: Inspiratory muscle training (IMT)

Interventions

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.
