The Buffalo Concussion Treadmill Test (BCTT) has been used to treat autonomic dysfunction in concussions. Here is the peer-reviewed article by Leddy and Willer from 2013 “Use of graded exercise testing in concussion and return-to-activity management“. Autonomic dysfunctions show up in symptom reports as sleep difficulties (too much or too little), anxiety or other emotional disorders. A relatively un-researched area in association with concussion is Postural Orthostatic Tachycardia Syndrome (POTS) in which with rapid changes of posture (standing up quickly) the client experiences temporary significant increase in heart rate. At Mspar we also measure autonomic function with heart rate variability (HRV) readings. In some cases a client will use a Polar H7 heart rate monitor and the Elite HRV app to take HRV readings over a period of time. This helps us measure the response to the treatments provided.
Treatments include prescribed exercise as suggested in the above article, meditation, desensitization exercises for postural changes and referral for psychological counselling.
I believe these autonomic dysfunctions are an area that will be showing up more in the research in the near future and this should allow up as practitioners to be more specific and effective in our treatments.
