A Study to Analyze Symptoms Prevalent in Early PD (Dysphonia, Tremor)
A Study to Analyze Symptoms Prevalent in Early PD (Dysphonia, Tremor)
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.
Participants will be asked to complete a series of activities, as outlined below.

 1. They will be asked to turn on "Do Not Disturb" and set their smartphone's volume to the
 maximum. This is to ensure that they can hear narrated instructions guiding them through
 the activities to come, and that data collection is uninterrupted.

 2. Volunteers will sustain the short a vowel sound for 10 seconds. This is to analyze
 PD-related dysphonia.

 3. Volunteers will place their smartphone in their left hand and rest it in their lap for
 10 seconds. This is to analyze PD-related rest tremor on the left side of the body.
 (Duration: 10 seconds)

 4. Volunteers will place their smartphone in their right hand and rest it in their lap for
 10 seconds. This is to analyze PD-related rest tremor on the right side of the body.
 (Duration: 10 seconds)

 5. Volunteers will hold their smartphone face-down at shoulder-level, in their left hand.
 This is to analyze PD-related postural tremor on the left side of the body. (Duration:
 10 seconds)

 6. Volunteers will hold their smartphone face-down at shoulder-level, in their right hand.
 This is to analyze PD-related postural tremor on the right side of the body. (Duration:
 10 seconds)

 Finally, participants will be asked to indicate their gender, age group, and status (whether
 or not they have PD), for data-labeling purposes. Please note that all data is collected
 anonymously and thus cannot be tracked down to a specific participant. Nevertheless, it will
 be encrypted and stored in a secure database, with each participant corresponding to a GUID
 (Global Unique Identifier), although participants will not be asked for their name. As this
 is not a medical study, there are no expected medical side effects, however, certain
 activities and questions may seem frustrating and boring.

 Participants will mainly benefit from the study indirectly, as it will increase understanding
 of symptoms prevalent in early PD, and may contribute to the development of diagnostic tools.
