Study Details

Brief summary:

This is a web-based study that involves monitoring hallmark symptoms of Parkinson's Disease (PD), specifically dysphonia and tremor, using smartphone sensor data. The entire length of the study will only take 5 minutes, so volunteers will not have to repeatedly contribute data. The study is made up of 5 short, 10-second long activities, which include sustaining the short a vowel sound to monitor changes in vocal fundamental frequency and holding a smartphone in different positions on either side of the body to measure changes in amplitude. To be a part of this study, volunteers must have an iPhone that is running on the software iOS 13 or higher, because they will be asked to download a smartphone application from an online App Store.

Interventions and Outcome Measures

Arms

Control (healthy, non-PD participants)

An audio file made up of a voice recording of the sustained short a vowel sound, along with accelerometer data while maintaining various positions, will be collected.

PD

An audio file made up of a voice recording of the sustained short a vowel sound, along with accelerometer data while maintaining various positions, will be collected.

Interventions

Smartphone microphone sensor

The volunteer will record themselves sustaining the short a vowel sound for 10 seconds.

Smartphone accelerometer sensor

The volunteer's smartphone's accelerometer will record accelerometer data (positions on the x, y, and z axes) while the volunteer maintains 4 positions, each for 10 seconds.

Primary outcome measure

  • PD-related Tremor [ Time Frame: 40 seconds ]
  • PD-related Dysphonia [ Time Frame: 10 seconds ]
