NCT05913882

Brief Summary

The goal of this interventional trial is to learn about lung volume recruitment (LVR) and expiratory muscle strength training (EMST) in a total of up to 39 patients diagnosed with ALS. The following aims will be addressed:

  1. 1.Determine the impact of combined LVR and EMST on cough strength and respiratory function in individuals with ALS.
  2. 2.Determine the impact of combined LVR and EMST on patient-reported dyspnea and bulbar impairment.
  3. 3.Describe the effect of combined LVR and EMST on patient- and caregiver reported burden and quality of life.

Study Arms (1)

Lung Volume Recruitment +Expiratory Muscle Strength Training

EXPERIMENTAL

All enrolled participants will commence a combined lung volume recruitment and expiratory muscle strength training exercise regimen following a 5-week no-intervention lead-in period.

Device: Respiratory Muscle Strength Training (LVR+EMST)

Interventions

Combined respiratory muscle strength training regimen that will be completed daily for 5 weeks.

Lung Volume Recruitment +Expiratory Muscle Strength Training

Eligibility Criteria

Age18 Years - 90 Years
Sexall
Healthy VolunteersNo
Age GroupsAdult (18-64), Older Adult (65+)

You may qualify if:

  • A diagnosis of probable or definite ALS in accordance with the Revisited El-Escorial Criteria.
  • Disease duration from symptom onset of ≤ 2 years,
  • Lung volume recruitment and expiratory muscle strength training naïve,
  • Reduced peak cough flow (% predicted for age and gender).

You may not qualify if:

  • History of stroke, head and neck cancer or other concomitant disorder that might contribute to dysphagia or respiratory impairment.
  • Use of prescription cough assist or non-invasive volume ventilation devices.
  • Enrollment in another research investigation that might impact cough or respiratory function.
  • Diagnosis of frontotemporal dementia or advanced cognitive impairment.
  • Tracheostomy placement/Use of invasive mechanical ventilation.
  • Contraindications for respiratory training (i.e., history of pneumothorax, severe chronic obstructive pulmonary disease).
