To evaluate the effectiveness of an acute period of cognitive and physical rest
Fifty consecutive patients with a diagnosis of concussions.
Participants were evaluated before (n
= 25) and after (n
= 25) a policy change that incorporated cognitive and physical rest
. Patients in the rest group were withheld from activities, including classes, for the remainder of the injury day and the following day, whereas patients in the no-rest group were not provided any postinjury accommodations.
Patients were evaluated on a graded symptom checklist, Balance Error Scoring System, Standard Assessment of Concussion
, and computerized neuropsychological tests. The number of days until each test achieved baseline values was compared between groups with independent-samples t
The no-rest group achieved asymptomatic status sooner than the rest group (5.2 ± 2.9 days and 3.9 ± 1.9 days, respectively; P
= .047). There were no differences between groups for time to baseline values on the Balance Error Scoring System, Standard Assessment of Concussion
, computerized neuropsychological tests, or time to clinical recovery
A prescribed day of cognitive and physical rest
was not effective in reducing postconcussion recovery
time. These results agree with a previous study and suggest that light activity postconcussion may not be deleterious to the concussion recovery
