Is Rest After A Concussion The Best Treatment?

Do you live in Ottawa? Are you wondering whether rest after a concussion is the best treatment?

If so, you are in the right place.

Today I discuss how research shows that rest after a concussion may be an outdated approach to treating concussion.

Let’s begin by seeing why rest has been a mainstay of concussion management for years.

Why Has Rest After A Concussion Been A Mainstay?

Rest has been the mainstay of concussion management for years.

Doctors base this approach to the treatment of concussions on three central ideas.

  • Firstly, the energy crisis caused by a concussion renders the brain vulnerable to physical and physiological stress.
  • Secondly, it keeps the patient more comfortable and less at risk of exacerbating symptoms.
  • Thirdly, studies have shown that patients engaged in higher levels of cognitive and physical activity post-concussion have taken longer to recover.

However, is rest after a concussion the right approach?

Let’s look at what the research says about rest after a concussion.

What is the evidence?

Research does not support the strategy of complete downtime following a concussion.

In 2002, researchers found no difference in outcomes with bed versus no bed rest in the week after a concussion.

In 2013 a study concluded that the recommendation for cognitive rest had no significant association with recovery time.

In 2016, researchers found that two days of complete cognitive and physical rest did not improve recovery.

Let’s now look at whether rest after a concussion lengthens recovery times.

Does Rest A Concussion Lengthen Recovery Times?

In 2015, researchers carried out a randomized control trial to examine the effect of recovery times of 5 days of strict rest compared to 5 days of usual care.

Usual care consisted of 1-2 days of respite and a gradual return to activities.

Results showed that the participants in the strict respite group had increased symptom reporting and slower resolution of symptoms.

Let’s now look at the risks of rest after a concussion.

What Are The Risks of Rest After A Concussion?

Health professionals traditionally interpret respite as lying in a dark room, limiting noise, no school, no work, no use of electronics, and no reading or cognitive exertion.

However, what happens when symptoms persist despite downtime?

There is no evidence that continued respite improves outcomes in persistent cases.

Furthermore, continued rest is not without risks, including reinforcement of symptoms such as depression, withdrawal, social isolation, generalized anxiety, physical deconditioning, insomnia, and missed academic/work time.

Let’s now look at when to introduce physical activity after a concussion.

What about Physical Activity?

In a 2016 study, researchers investigated the association between physical activity within seven days post-concussion and the incidence of symptoms.

The researchers found that 69.5% of participants who participated in light aerobic exercise within seven days of injury had a lower risk of persistent symptoms.

Another recent 2018 study looked at the time of initiation of aerobic exercise and whether it influenced recovery time.

The researchers found that early participation in aerobic exercise was associated with faster recovery, and the longer that exercise was delayed, the longer the recovery time.

The study supports the early (within one week) start of sub-symptom threshold aerobic exercise.

In 2017, researchers published a consensus guideline on concussion regarding rest to alleviate symptoms and promote recovery.

“There is currently insufficient evidence that prescribing complete rest achieves these objectives. After a brief rest period during the acute stage (24-48 hours) after injury, patients can be encouraged to become gradually and progressively more active while staying below their cognitive and physical symptom-exacerbation thresholds.”

What Can We Take Away?

Research shows that intense cognitive/physical activity in the acute stage of concussion may be harmful.

Furthermore, strict rest has also been shown to ineffective and potentially dangerous!

Current consensus guidelines recommend 1-2 days of complete rest and a gradual return to activity.

However, these guidelines still leave us what rest involves, which activity should be introduced, and when.

Such a cookie-cutter approach is unlikely to work.
