A Novel Digital Music-based Autonomous Personalized Walking Intervention to Improve Gait and Walking Automaticity in Parkinson Disease

Inclusion Criteria: * Self-report of diagnosis of typical Parkinson disease determined by a medical doctor * ≥ 40 years of age * Community-dwelling (e.g. home, independent living, senior housing) * Have stable PD medications for at least two weeks prior to enrollment * Modified Hoehn and Yahr stages 1-3 per physical exam by a licensed physical therapist * Able to walk independently without physical assistance for at least 10 minutes (assistive devices allowed with reciprocal gait pattern) * Willing and able to provide informed consent * Provide HIPAA Authorization to allow communication with the primary healthcare provider for communication (as needed) during the study period Exclusion Criteria: * \< 40 years of age * Diagnosis of atypical Parkinsonism * Modified Hoehn and Yahr stages 4-5 * Significantly disturbing freezing episodes during daily walking based on the New Freezing of Gait Questionnaire (Part III Item 7) * Fall frequencies \>1x/week on average, over the past month. * Currently participating in physical therapy for Parkinson gait rehabilitation * Currently performing walking exercise at moderate intensities or higher for at least 30 min. per session ≥ 3x/week * Self-reported cardiac problems that interfere with the ability to safely exercise (e.g., congestive heart failure, uncontrolled cardiac arrhythmias, chest pain; * Orthopedic problems in the lower extremities or spine that may limit walking distance (e.g., severe arthritis, spinal stenosis, or significant pain) * Any other medical conditions that would preclude successful participation as determined by the researcher/ physical therapist * Cognitive impairment (i.e., Montreal Cognitive Assessment, MoCA \< 21) * Unable to walk independently (i.e., without physical assistance) at a comfortable speed ≥ 0.4m/s as measured using the 10-meter Walk Test (10mWT) as examined in Baseline #1 * Resting tachycardia (\> 100 beats/min) or uncontrolled blood pressure (resting systolic BP \> 160 mmHg or diastolic BP \>100 mmHg)) as measured by the researcher/ physical therapist * Unable to independently use the music-based digital therapeutic during training * Significant hearing impairment
