Washington DC: A new American research suggests that a specialised
exercise routine can help athletes suffering with post-concussion syndrome
(PCS) get back on the field.
According to the study conducted by University of Buffalo researchers, a
progressive exercise regimen developed individually for each participant,
carried out at levels just below the onset of symptoms, is safe and can
mitigate nearly all PCS symptoms.
The findings of the study contradict the much-believed idea that PCS
patients should be given rest, reassurance and antidepressants and
physical activity should be avoided.
Barry Willer, senior author of the study and UB professor of psychiatry
and rehabilitation sciences, said: "Perhaps the most exciting aspect of
this study is that all of the subjects that participated, both athletes
and non-athletes, got better eventually, although the athletes certainly
improved the fastest.
"It also was reassuring to discover that the use of exercise was safe and
did not prolong symptoms, a worry expressed by other practitioners."
For reasons not yet known, 5-10% of people who experience a concussion
have symptoms that last beyond six weeks. These persons are diagnosed with
PCS.
The UB regimen is based on the premise that the regulatory system
responsible for maintaining cerebral blood flow, which may be
dysfunctional in people with a concussion, can be restored to normal by
controlled, graded and symptom-free exercise.
The team designed their program in 2004.

Abstract
Objective:
To evaluate the safety and effectiveness of subsymptom
threshold exercise training for the treatment of
post-concussion syndrome (PCS).
Design:
Prospective case series.
Setting:
University Sports Medicine Concussion Clinic.
Participants:
Twelve refractory patients with PCS (6 athletes and 6
nonathletes).
Intervention:
Treadmill test to symptom exacerbation threshold (ST) before
and after 2 to 3 weeks of baseline. Subjects then exercised 5 to 6 days
per week at 80% ST heart rate (HR) until voluntary peak exertion without
symptom exacerbation. Treadmill testing was repeated every 3 weeks.
Main Outcome Measures:
Adverse reactions to exercise, PCS symptoms, HR,
systolic blood pressure (SBP), achievement of maximal exertion, and return
to work/sport.
Results:
Pretreatment, ST occurred at low exercise HR (147 27 bpm) and
SBP (142 6 mm Hg). After treatment, subjects exercised longer (9.75 6.38
minutes to 18.67 2.53 minutes, P = .001) and achieved peak HR (179 17
bpm) and SBP (156 13 mm Hg), both P < .001 versus pretreatment, without
symptom exacerbation. Time series analysis showed significant change in
rate of symptom reduction for all subjects and reduced mean symptom number
in 8/11. Rate of PCS symptom improvement was related to peak exercise HR
(r = -0.55, P = .04). Athletes recovered faster than nonathletes (25 8.7
vs 74.8 27.2 days, P = .01). No adverse events were reported. Athletes
returned to sport and nonathletes to work.
Conclusions:
Treatment with controlled exercise is a safe program that
appears to improve PCS symptoms when compared with a no-treatment
baseline. A randomized controlled study is warranted.
