1
00:00:00,535 --> 00:00:04,320
- How long after concussion can I get back to physical activity?

2
00:00:04,320 --> 00:00:07,040
Do I have to sit in a dark room all by myself?

3
00:00:07,501 --> 00:00:10,249
(soft music)

4
00:00:11,086 --> 00:00:13,000
- That's an excellent question.

5
00:00:13,000 --> 00:00:16,558
Previous protocol have always prescribed rest until asymptomatic.

6
00:00:16,800 --> 00:00:18,840
While rest plays an important role

7
00:00:18,840 --> 00:00:20,459
for the first 24 to 48 hours,

8
00:00:20,459 --> 00:00:22,627
prolonged rest can actually negatively

9
00:00:22,627 --> 00:00:25,280
impact recovery and mental health.

10
00:00:26,000 --> 00:00:29,615
Our study is the first real-world randomized clinical trial

11
00:00:29,615 --> 00:00:32,656
to assess whether early return to physical activity is safe

12
00:00:32,656 --> 00:00:35,696
and may reduce symptoms at two weeks.

13
00:00:35,696 --> 00:00:38,394
456 patients with acute concussion

14
00:00:38,394 --> 00:00:42,127
were recruited here at CHEO and at two other sites in Ontario,

15
00:00:42,127 --> 00:00:44,966
and were randomized into two different groups.

16
00:00:44,966 --> 00:00:48,038
The first group was returning early to physical activity

17
00:00:48,038 --> 00:00:49,659
even if symptomatic,

18
00:00:49,659 --> 00:00:52,542
and the second group was to return to physical activity

19
00:00:52,542 --> 00:00:54,571
once completely asymptomatic.

20
00:00:54,571 --> 00:00:58,451
All children wore an accelerometer to track their movement behavior,

21
00:00:58,451 --> 00:01:01,697
and we looked at their symptoms at two weeks.

22
00:01:01,697 --> 00:01:05,135
We have shown that it is safe to return to physical activity

23
00:01:05,135 --> 00:01:07,415
at 72 hours post-injury,

24
00:01:07,457 --> 00:01:09,436
and in those that adhere to the protocol

25
00:01:09,436 --> 00:01:12,380
it may actually reduce symptoms at two weeks.

26
00:01:12,380 --> 00:01:14,955
We encourage physician to prescribe physical activity

27
00:01:14,955 --> 00:01:18,776
at 72 hours in children with a concussion.
