Exercise as Concussion Therapy Trial- 2

Phase 2

Withdrawn

• Conditions: Mild Traumatic Brain Injury; Concussion, Mild

• Registration Number: NCT04578743
• Lead Sponsor: ANSwers Neuroscience, Inc.

Brief Summary

This study is a Phase 2, open-label study of a therapeutic intervention (graded exercise)compared to a reference therapy (passive stretching) in patients who have sustained mTBI. Subjects will be randomly assigned with a ratio of 1:1 to complete either graded exercise or passive stretching using a parallel-group design.

The effects of graded exercise and passive stretching will be compared using ClearPlay© (ANSwers Neuroscience Pty Ltd commercial mobile application)

The study will also validate the performance of two devices:

1. ClearHeart©, ANSwers Neuroscience Pty Ltd commercial prototype for cold pressor testing, compared to ice bucket testing.

2. ClearPlay©, ANSwers Neuroscience Pty Ltd commercial prototype based on the joint position error test to assess "whiplash".
