Stroke patients with dysphagia have restrictive lung dysfunction and impaired cough response. This pilot study was performed to determine if Mechanical Insufflation Exsufflation (MIE) therapy can help recover impaired cough function.
Mechanical Insufflation- Exsufflation (MI-E) is an assisted coughing machine that has been proven to be very effective in preventing the deterioration of pulmonary function in patients with degenerative neuromuscular disorders. Impaired airway clearance in stroke patients is associated with increased incidence of aspiration pneumonia.
In this pilot study the investigators attempt to assess the efficacy of MI-E as part of a protocol for patients with dysphagia with impaired cough response.
- Mechanical Insufflation Exsufflation Device
Intervention Desc: Mechanical Insufflation Exsufflation -Each patient received daily treatments by means of a light-weight, elastic oronasal mask. Treatments were divided between morning and afternoon and were carried out 5 times a week. A total of 20 sessions were carried out by a a trained respiratory therapist.
