NCT04288804

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.

Outcome Measures

Primary Outcomes (2)

  • PD-related Tremor

    24 features, composed of mean absolute deviation and mean standard deviation for each axis (x, y, z), for 4 likely occurrences of tremor, will be observed by looking at the accelerometer data file of each participant.

    40 seconds

  • PD-related Dysphonia

    Features, composed of vocal fundamental frequency, and similar measures to jitter and shimmer, will be observed by looking at the mel spectrogram for the audio file of each participant.

    10 seconds

Study Arms (2)

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.

Device: Smartphone microphone sensorDevice: Smartphone accelerometer sensor

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.

Device: Smartphone microphone sensorDevice: Smartphone accelerometer sensor

Interventions

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

Control (healthy, non-PD participants)PD

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.

Control (healthy, non-PD participants)PD

Eligibility Criteria

Healthy VolunteersYes
Age GroupsChild (0-17), Adult (18-64), Older Adult (65+)
Sampling MethodProbability Sample
Study Population

Subjects must be healthy controls, or clinically diagnosed with PD in order to participate. They also may not have another illness that causes tremor and/or dysphonia - subjects who have PD must also have PD-related dysphonia and PD-related tremor.

You may qualify if:

  • Clinical diagnosis of Parkinson's Disease (PD)
  • Healthy

You may not qualify if:

  • Subject does not have clinical diagnosis of PD, however, has another neurological disorder/disease that manifests with symptoms of tremor or dysphonia
  • Subject diagnosed with PD does not have dysphonia and tremor
