简要总结
A post-concussion syndrome (PCS) diagnosis has historically led to a recommendation of continued mental and physical rest to minimize symptoms. However, this conservative approach does not consider the pathophysiological mechanisms and neurological subsystem dysfunction which mediate persistent signs and symptoms. Recently, developing research is recommending targeted therapies for specific post-concussion disorders (physiologic, vestibulo-ocular and cervicogenic). The Buffalo Concussion Treadmill Test (BCTT) is a graded aerobic test that has emerged as safe, reliable, and effective in distinguishing between post-concussion syndrome sub-types, quantifying physiological recovery, and guiding return to play decision making. It has been proposed that the results of a BCTT can be used to prescribe progressively intensifying whole body aerobic exercise (such as walking or biking), maintained at a sub-symptom threshold, to improve autoregulatory function with the potential to improve PCS symptoms. Positive results with BCTT have now made it the standard of care at the University of Buffalo Concussion Clinic and Pan Am Clinic during the management of sport related concussions. Despite its increased use in patients with post-concussion syndrome there is currently no data on the use of exercise treatment in the early stages of concussion recovery.
详细描述
This is a randomized controlled trial of sub-threshold (symptom-threshold) exercise therapy versus relative rest treatment in subjects with an acute phase concussion.
If a participant is eligible and consent has been given the neurosurgeon will conduct a Physical Activity Readiness Medical Examination (PARmed-X) and the participant will complete an exercise tolerance test on a treadmill (Visit 1) under the supervision of the neurosurgeon and exercise scientist. Using a standardized Balke protocol, participants will perform an incremental treadmill test to the point of symptom onset of exacerbation (increase of 2 points on an overall condition Likert scale). Those who achieve a peak Heart Rate (HR) > 150 bpm will be excluded from the study since they are close to full recovery. Those who achieve a HR > 120 but < 150 bpm and who cannot exercise to exhaustion (defined as a final rating of perceived exertion (RPE) < 17 on a Borg scale) will be randomly assigned to sub-threshold aerobic exercise (exercise at a HR equivalent to 80% of their HR achieved at symptom onset or exacerbation) or to relative rest. Any participant who does not achieve a HR > 120 bpm will return the following week for a repeat treadmill test (Visit 2). If they achieve a HR > 120 bpm but cannot exercise to exhaustion during Visit 2, they will be randomly assigned to sub-threshold exercise or to relative rest. This is because participants must demonstrate a level of exercise tolerance to have a reasonable sub-threshold (80% of achieved HR) exercise treatment prescription.
Participants randomized to sub-threshold aerobic exercise will be given a HR monitor and a specific HR intensity to exercise at 30 minutes per day. Participants randomized to rest will be asked to rest for 30 minutes per day (no structured physical or cognitive activity for at least 30 minutes per day and no participation in structured aerobic exercise during the entire study). After randomization, all subjects will have treadmill testing at all subsequent follow-ups with the neurosurgeon (every 1 to 2 weeks) to determine physiological recovery. All participants will be asked to document their symptom data into a form between 7-10 PM each evening (following that day's exercise for the exercise group), along with hours of work/school, and minutes of exercise.
The study end point for each subject is at recovery (as determined by a normal exercise level and an exam from the treating neurosurgeon).
