Trial Title: Masked Faces in Parkinson Disease: Mechanism and Treatment

Study Design Characteristics:
- Allocation: RANDOMIZED
- Intervention Model: PARALLEL

- Primary Purpose: TREATMENT
- Time Perspective: None
- Masking: DOUBLE
- Phase: PHASE2
- Number of Arms: 2.0

Eligibility Criteria:
Inclusion Criteria:~* A clinical diagnosis of idiopathic Parkinson disease~* Hoeh-Yahr Stage 1-3 when off medication~* Stable and optimal medical regimen for at least 3 months~* No previous surgical interventions for Parkinson's disease (i.e., deep brain stimulation, pallidotomy, stem cell implantation)~* Participants will include men and women between the ages of 45 and 80 years~Exclusion Criteria:~* Evidence of dementia based on neurocognitive testing~* Current or past history of major psychiatric disturbance (e.g., schizophrenia, bipolar disorder, substance abuse). Participants who are taking anti-depressants will not be excluded as long as they are not currently depressed (Beck Depression, SCID)~* Other neurologic disturbance (e.g., tumor, stroke, traumatic brain injury, epilepsy) or severe chronic medical illness (e.g., HIV, metastatic cancer)~* Presence of oro-facial dyskinesias~* Previous surgeries to the larynx that result in poor vocal fold closure and/or positive history of head and neck cancer~* History of smoking in the past 5 years~* Untreated hypertension~* Failing a baseline test of pulmonary function during baseline respiratory evaluation~* Known respiratory complications such as chronic obstructive pulmonary disease (POCD), asthma~* Previous surgical interventions for Parkinson's disease (i.e., deep brain stimulation, pallidotomy, stem cell implantation)

Study Arms:
- High Intensity Muscle Strength Training (Type: ACTIVE_COMPARATOR): This arm involved high intensity muscle strength training at 75% maximum inspiratory pressure (MIP). Training took place for 4 weeks, 5 days a week. Each daily session involved 5 sets of breathing exercises that required participants to take deep breaths (i.e., inspire) using use a breathing device. Settings on the breathing device were determined by obtaining the individual's maximal inspiratory pressure (MIP)using a specialized breathing gauge. The MIP was determined at the beginning of each week and the training device was adjusted and set at 75% MIP. Exercises took place in home setting, with weekly visit by staff. Participants kept daily exercise log.
- Sham MST (Type: SHAM_COMPARATOR): This arm (low intensity MST) was identical to the real intervention in all ways except that the training device was set at 5% maximum inspiratory pressure (MIP). Thus less muscle and breathing effort was required during this sham treatment.

Based on this trial design, predict the completion outcome and termination type (if applicable).
