Range of Motion Active Task Export Format

  • Updated
Follow

The Range of Motion Active Task is based on the ResearchKit Range of Motion task. The Range of Motion task can be configured for either the knee (left or right) or shoulder (left or right).

When your project uses the CSV export format for Survey Results, data for Active Tasks is exported in the file SurveyRangeOfMotionResults.csv. When your project uses the JSON export format, Active Task data is included in the file SurveyResults.json.

For a typical survey using this task, you'll expect to see:

  • One survey result each time the participant completes the survey.
  • One Range of Motion result for each administration.
