BC's Updated Concussion Guidelines: What They Mean for Your Recovery

For years, the standard advice after a concussion was simple: rest in a dark room until your symptoms resolve. Do not exercise. Avoid screens. Stay quiet. That guidance is now outdated. BC's 2024 clinical guideline on concussion and mild traumatic brain injury formally abandoned the prolonged-rest model and replaced it with one of the most consequential shifts in concussion management in two decades: early assessment and active, graded recovery. If you or someone you know is recovering from a concussion under the old rest-first protocol, this is worth reading.

What the BC 2024 Concussion Guideline Says

The BC Guideline on Concussion/Mild Traumatic Brain Injury was developed by the Guidelines and Protocols Advisory Committee (GPAC) and represents the current standard of care in British Columbia. The 2024 edition (with a minor administrative revision in May 2025) makes several evidence-based clinical recommendations that depart significantly from older approaches:

• Early assessment is recommended — ideally within 24 to 48 hours of injury — by a physician, nurse practitioner, or other qualified health professional.
• Prolonged rest is not recommended. The guideline explicitly states that strict rest beyond the first 24 to 48 hours does not improve outcomes and may worsen them.
• Graded return-to-activity should begin early, guided by a structured protocol that advances based on symptom response to activity.
• Active rehabilitation — including aerobic exercise — is recommended for persistent concussion symptoms, based on strong evidence from the Buffalo Concussion Treadmill Test research.
• Physiotherapy is specifically identified as having a role in cervicogenic headache management, vestibular rehabilitation, and supervised return-to-sport or return-to-work progressions.

Why Rest Alone Is No Longer the Standard

The old rest model was based on a reasonable hypothesis: a concussed brain needs metabolic recovery, and any demand placed on it would slow that process. Subsequent research — including landmark work from the University at Buffalo — showed the opposite. Controlled aerobic exercise, introduced at sub-symptom threshold levels, accelerates recovery in most concussion patients. It improves cerebral blood flow regulation, reduces autonomic dysfunction, and breaks the deconditioning cycle that sustains many post-concussion symptoms. The 2024 BC guideline reflects this body of evidence.

What Active Recovery Actually Looks Like

Active recovery from a concussion is not the same as returning to sport or full work capacity. It is a carefully graded progression through defined stages, each with specific activity criteria and symptom monitoring. The standard return-to-activity protocol (based on the Concussion in Sport Group's Berlin Guidelines, referenced in BC's protocol) involves six stages: complete rest (stage 1, maximum 24 to 48 hours), light aerobic activity, sport-specific exercise, non-contact drills, full contact practice, and return to full activity. Each stage requires at least 24 hours at the preceding level without symptom provocation. A physiotherapist with concussion training monitors this progression, adjusts it based on your symptom response, and addresses secondary contributors — including cervicogenic headache, vestibular disruption, and oculomotor dysfunction — that often sustain symptoms beyond the initial recovery period.

Cervicogenic and Vestibular Components

One of the most underappreciated findings in concussion research is that a significant proportion of post-concussion headache, dizziness, and fogginess is not brain-origin — it is cervicogenic (arising from the upper cervical spine) or vestibular in nature. These conditions respond to specific physiotherapy interventions: manual therapy for the upper cervical spine, gaze stabilisation exercises, habituation exercises for vestibular sensitivity, and balance retraining. Under the 2024 BC guideline, identifying these secondary contributors is an explicit part of assessment. If your post-concussion care does not include cervical assessment and vestibular screening, it is incomplete.

When to Seek Physiotherapy After a Concussion in BC

The 2024 guideline recommends early professional assessment. Physiotherapy is appropriate as part of a multidisciplinary response — particularly for patients with symptoms that persist beyond 10 to 14 days (post-concussion syndrome), those with vestibular or cervicogenic components identified by assessment, athletes needing a supervised return-to-sport protocol, and workers needing a documented return-to-work progression. Physiotherapy for concussion in BC can be accessed with or without a doctor's referral. If your concussion is associated with a motor vehicle accident, ICBC covers physiotherapy directly.
