HeadX Duo
Read full descriptionHide full description
HeadX Duo is the companion app for the HeadX Duo wearable device. Designed for trained professionals, it acquires, calculates, records and displays angular movement during supported head, trunk and limb protocols. Connect your Duo, follow on-screen recording steps, review individual session records, export recorded data and manage firmware updates. Session data is stored locally on your mobile device and can be exported when needed. The app does not classify results as normal or impaired, recommend treatment, or determine treatment response, recovery or return to activity. A compatible HeadX Duo wearable is required. Use only the supported protocols and configurations described in the instructions for use.
