Every year approximately 2.8 million people are diagnosed with a mild traumatic brain injury (mTBI) and often report exercise intolerance. Currently intolerance is categorized into a binary pass/fail, but we might be missing valuable information such as max heart rate (HRmax) achieved and symptom provocation during exercise. Changes to percent HRmax and symptom provocation may provide insight on recovery. Our aim is to explore HRmax and symptom changes in people classified as exercise tolerant versus intolerant before and after multimodal rehabilitation.
