The 6-Minute Walk assessment is a direct translation of the 6 minute walk test that measures aerobic capacity and endurance over the course of a 6-minute walk with the phone in a participant’s pocket. Data collected from this assessment includes steps, distance traveled by GPS differentials, x,y,z accelerometer readings (at ~100Hz) and rotation rates from the gyroscope.

Sample Data
The Tremor assessment is a multi-part activity measuring resting tremor, postural tremor, and kinetic tremor. All activities are performed by each hand separately while holding the phone. Each activity takes 30 seconds per hand. Resting tremor is performed by the participant sitting in a chair while holding the phone in their lap. Postural tremor is performed by holding the phone outstretched at shoulder level. Kinetic tremor uses an adaptation of the finger to nose test where the participant moves the phone from outstretched to touching their nose repeatedly. Data collected from this assessment includes x,y,z accelerometer readings (at ~100Hz) and rotation rates from the gyroscope.

The Walk and Balance assessment is a multi-part activity measuring gait disturbance and motor function similar to a number of traditional assessments: the 25 ft walk, gait analysis, and a stand test. Walk and Balance consists of two sub-assessments: (1) the participant walks for 30 seconds with their phone in their pocket, and (2) the participant turns around 360 degrees then stands still for 30 seconds. Data collected from this assessment includes x,y,z accelerometer readings (at ~100Hz) and rotation rates from the gyroscope.

Sample Data
The Finger Tapping assessment measures motor function and finger dexterity by having participants alternately tap 2 fingers on the touchscreen within defined target areas. Data collected from this assessment includes the timing and position of each screen touch, information on whether the buttons were touched, and motion data for QC purposes.
