Digital Health Tools and Assessments

Interactive Assessments

Wearable Integrations, Passive Data & Survey-Based PROs

To complement the interactive assessments that can be incorporated into a digital health research study, Sage has used the following data collection modalities:

Digital Jar Open

The Digital Jar Open assessment measures the functional range of motion without pain for the joints of the arm (wrist, elbow, shoulder) on each arm while rotating inward and outward.

Toe Imaging

The Toe Imaging assessment allows a participant to take a photo of the digits of each foot to assess symptoms related to joint swelling and nail dystrophy. Data collected include a jpeg image of each foot.

Finger Imaging

The Finger Imaging assessment allows a participant to take a photo of the digits of each hand to assess symptoms related to joint swelling and nail dystrophy. Data collected include a jpeg image of each hand.

Joint Counting

The Joint Counting assessment allows a participant to select a given set of joints on the body for a binary yes/no as to whether each joint is affected. Data collected include the affected joints and a jpeg image summary.

Body Area Draw

The Body Area Draw assessment allows a participant to use the touch screen to draw the extent to which an area of the body is affected by a given symptom. Data collected include the calculated percentage of the body surface area and a jpeg image summary. 

Body Area Imaging

The Body Area Imaging assessment allows a participant to select an area of the body and use the phone camera to capture an image of this area. Data collected include the location of the body selected and a jpeg image.

Phonation

The Phonation assessment is an adaption of a clinical test where a participant makes an extended “ahhhhh” sound for 20 seconds.  Data collected from this assessment includes an audio recording.

Heart Rate

The Heart Rate assessment measures the pulse of a participant using the smartphone camera and flash. The assessment monitors blood flow through the tip of the finger over the course of 20 seconds.

Heart Rate Recovery

The VO2max, or Heart Rate Recovery assessment is an adaption of the Tecumseh step test that measures VO2Max using the smartphone camera and flash.

6-Minute Walk

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.

Tremor

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.

Walk and Balance

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.

Finger Tapping

The Finger Tapping assessment measures motor function and finger dexterity by having participants alternately tap 2 fingers on the touchscreen within defined target areas.

Mobile Toolbox Cognitive Tests

Memory for Sequences

Memory for Sequences is a working memory assessment that asks participants to recall an alphanumeric string and reorganize/cognitively manipulate it and produce a new output

Dimensional Change Card Sort

Dimensional Change Card Sort (DCCS) tests executive function by asking participants to tap on one of the two pictures presented in response to either the SHAPE or COLOR prompt as fast as possible.

Picture Sequence Memory

PSM asks participants to drag the picture/item in the correct order of the sequence to assess episodic memory.

Number Match

Number match is an episodic memory assessment. Participants fill in items, one row at a time, according to a code/legend on the top of the screen.

Vocabulary

This assessment measures the participant's vocabulary and ability to identify synonyms.

Spelling

A language test. Participants type spelling of orally presented English words.

Flanker

Indicate the direction of a central arrow flanked by foils on each side presented in the same (congruent) and opposite (incongruent) orientations.

Face Name Associative Memory Exam

Participants see a series of facial photos and names and are asked to remember the face-name pairs.
