Outcome Measures

Primary Outcomes (1)

  • Maximal inspiratory pressure (MIP)

    American Thoracic Society standards

    Change between baseline (enrolment) and 6 weeks

Secondary Outcomes (1)

  • Frenchay activities index

    Change between baseline (enrolment) and 6 weeks

Study Arms (2)

Sham inspiratory muscle training

SHAM COMPARATOR

Patients in the sham group used the threshold trainer (Threshold at IMT device URES HS730, Respironics, New Jersey, Inc, Cedar Grove, NJ, USA), with the diaphragm removed.

Device: Sham inspiratory muscle training (URES HS730)

Inspiratory muscle training

EXPERIMENTAL

Inspiratory muscle training will be by a threshold trainer (Threshold at IMT device URES HS730, Respironics, New Jersey, Inc, Cedar Grove, NJ, USA), a commercially available spring-loaded inspiratory muscle training device. It will be set at 40% of the subjects baseline maximal inspiratory pressure and increased by 10% each week by an unblinded assistant. All subjects were trained with these devices for 8-10 breaths, 3 times a day, everyday for 6 weeks

Device: Inspiratory muscle training (URES HS730)

Interventions

It will be set at 40% of the subjects baseline maximal inspiratory pressure and increased by 10% each week by an unblinded assistant. All subjects were trained with these devices for 8-10 breaths, 3 times a day, everyday for 6 weeks

Also known as: Threshold at IMT device URES HS730, Respironics
Inspiratory muscle training

Subjects in the control group underwent sham training, using the same device with the diaphragm removed, thus providing no resistance. They were not given frequency or duration but told to use the device when desired.
