Inspiratory and Trunk Muscle Activity During IMT on Stable and Unstable Surfaces in Stroke Patients

NCT06877338 · Status: NOT_YET_RECRUITING · Type: OBSERVATIONAL · Enrollment: 24

Last updated 2025-03-14

No results posted yet for this study

Summary

This study aims to investigate the differences in muscle recruitment of the diaphragm (assessed using ultrasound), the sternocleidomastoid (SCM) and trunk muscles (both measured via surface electromyography (sEMG)), during loaded breathing training performed on both stable and unstable surfaces. The goal is to understand the interaction between the inspiratory and trunk muscles during Inspiratory muscle training (IMT) across these two surface conditions.

Conditions

  • Stroke
  • Inspiratory Muscle Training
  • Diaphragm
  • Sternocleidomastoid Muscles
  • Trunk Muscle Activity

Interventions

OTHER

Loaded breathing on stable and unstable surfaces

Participants will be instructed to perform 10 loaded breaths via a threshold inspiratory load device on both a stable surface (sitting on a chair, Protocol 1) and an unstable surface (sitting on a soft pad, Protocol 2) in random order. The inspiratory load/resistance will be set at 50% of the maximum inspiratory pressure (MIP).
