Description of intervention(s) / exposure
Treatment: Devices - Graded Exercise Therapy: ClearPlay(TM)

Experimental: Graded Exercise - ClearPlay(TM): a novel therapeutic intervention, downloadable to an Apple i-touch or i-phone device, will provide a telemetry-based graded exercise program for 20 minutes each day, identifying a heart rate target that will be advanced weekly for up to 8 weeks as symptoms resolve.

Experimental: Passive Stretching - ClearPlay(TM): we have created a passive stretching program (placebo arm) downloadable to an Apple i-touch or i-phone device, that will provide a telemetry-based guided passive stretching program for 20 minutes each day for up to 8 weeks as symptoms resolve.

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".
