Table 1 Inclusion and exclusion criteria

From: Design of the WHIP-PD study: a phase II, twelve-month, dual-site, randomized controlled trial evaluating the effects of a cognitive-behavioral approach for promoting enhanced walking activity using mobile health technology in people with Parkinson-disease

Inclusion criteriaExclusion criteria
▪ Diagnosis of idiopathic, typical PD according to the United Kingdom Brain Bank Criteria [20]
▪ Modified Hoehn & Yahr stages 1–3 (mild to moderate disease severity) [21]
▪ Live in the community
▪ Able to walk 10 continuous minutes without help from another person
▪ Stable on all PD medications for at least two weeks prior to study entry
▪ Moderately or significantly disturbing freezing episodes during daily walking (score of ≥ 2 on item 7 of the New Freezing of Gait Questionnaire (nFOGq)) [22]
▪ Significant cognitive impairment (i.e., Mini-Mental State Examination (MMSE) score of < 24) [23]
▪ Unstable medical or concomitant illnesses or psychiatric conditions, which in the opinion of the investigators would preclude successful participation
▪ Cardiac problems that interfere with ability to safely exercise (i.e., uncontrolled congestive heart failure, complex cardiac arrhythmias, chest pain or pressure, resting tachycardia (> 120 beats/min), uncontrolled BP (resting systolic BP > 180 mmHg or diastolic BP > 100 mmHg))
▪ Orthopedic problems in the lower extremities or spine that may limit walking distance (i.e., severe arthritis, spinal stenosis or pain)
▪ Engaged in a walking program for greater than 90 min per week for the past month
▪ Engaged in an exercise regime of moderate intensity for greater than 90 min per week for the past month
