New Trial into Effects of IMT in COPD Patients

A new clinical trial will be looking at the effects of inspiratory muscle training (IMT) on shortness of breath (dyspnea) and postural control in patients with COPD.

Shortness of breath in patients with COPD

Patients with chronic obstructive pulmonary disorder (COPD) experience shortness of breath, or dyspnea, during physical activity. It is related to weakness of their respiratory muscles. There is much evidence of IMT improving breathing muscle function and reducing the intensity of dyspnea.

Balance impairment in patients with COPD

Patients with COPD and pronounced respiratory muscle weakness also show impaired postural balance. But improvements in respiratory muscle function might improve balance control in patients.

Purpose of the controlled trial

The trial will consider whether eight week’s of controlled IMT will reduce the intensity and feeling of dyspnea. It will also investigate if it improves postural control. And finally it will look to see if IMT improves blood flow and oxygen delivery to a patient’s limb muscles too.

Inspiratory muscle training intervention

The trial will use the POWERbreathe KHP2 Inspiratory Muscle Training device for monitoring breathing parameters. And patients will each use a POWERbreathe Medic Plus twice a day, mostly in their home and without supervision. However they will perform one training session each week under supervision, during which the training load will be increased. A sham group will perform three daily sessions of 30 breaths and will train at a constant inspiratory load of no more than 10% of their initial Pi,max.

The Principal Investigator is Rik Gosselink, PT, PhD. The trial is open to all sexes ageing from 40 to 90 years of age. It will take place at the University Hospital Leuven, Belgium. And the estimated completion date for the trial is January 31st 2018.
