Intervention type: DEVICE
Group type: EXPERIMENTAL
Intervention: PowerLung trainer
Description: PowerLung trainer will be utilized which has both an inspiratory and expiratory loading capacity for training. A single daily training session will consist of three sets of 10 repetitions for a total of 30 inspiratory repetitions and 30 expiratory repetitions (i.e. 60 repetitions) for 5 days a week, for 3 months.

Group type: EXPERIMENTAL
Intervention: Micro Mouth Pressure Meter
Description: The participant will be seated with the nose occluded using a nose clip. After inhaling to total lung capacity, the participant will place his or her lips around the mouthpiece and blow out as forcefully as possible. A flange rubber mouthpiece will be used to overcome the inability of some individuals to create tight lip seal due to facial muscle weakness. Three trials will be performed and the patients highest Maximum Inspiratory Pressures (MIP) and Maximal Expiratory Pressure (MEP) used.

Group type: EXPERIMENTAL
Intervention: Pulmonary Function Testing
Description: Pulmonary Function testing will be performed using conventional methods and will include the following outcomes: forced vital capacity (FVC), sniff nasal inspiratory pressure (SNIP), peak expiratory flow (PEF), forced expiratory volume (FEV1) expressed as a percentage of predicted values.
