Concussion in Sports: A Physiotherapist's Guide to Assessment and Return to Play


Awareness of concussion in Indian sport is growing, and rightly so — with rising participation in cricket, football, rugby, hockey, martial arts, and cycling, head injuries are far more common than many realise. A concussion should never be dismissed as "just a knock to the head." Sound concussion management in physiotherapy for sports in India requires structured recognition, careful assessment, and patience through recovery.

Having worked with athletes across contact and collision sports for over two decades, I've seen how early, correct recognition changes outcomes dramatically. This guide walks through what a concussion actually is, how it's assessed today, and how athletes safely return to play.

What is a Concussion?

A concussion is a mild traumatic brain injury caused by a direct blow to the head or a force transmitted to the head from an impact elsewhere on the body, causing temporary disruption of brain function. It's considered a genuine brain injury, distinct from structural injuries like bleeds or fractures, because standard imaging typically appears normal despite real functional impairment. Symptoms can also be delayed by hours, which is why immediate recognition and cautious observation matter even when an athlete initially "seems fine."

Why Concussion is a Serious Sports Injury

A concussion causes temporary brain dysfunction affecting thinking, balance, and emotional regulation. The greatest immediate risk is repeat injury before full recovery, since a second impact during this vulnerable window can cause disproportionately severe effects. Beyond the acute period, concussion can affect cognitive function, balance, mood, sleep, and even academic or work performance — all reasons careful, individualised management matters far more than rushing back to sport.

Common Causes of Sports Concussion

Concussions commonly result from player-to-player collisions, falls, ball impact to the head, head-to-ground contact, cycling crashes, and strikes in combat sports, alongside acceleration-deceleration injuries where the head snaps rapidly. In Indian sport, this includes collisions in football and hockey, bouncer impacts in cricket, falls in cycling, and head strikes in martial arts.

Concussion Assessment on the Field

The immediate priority is removal from play, followed by a safety-focused assessment screening for red flags, close observation, and referral when necessary. No athlete with a suspected concussion should return to the same session, regardless of how quickly symptoms seem to settle. The guiding principle remains: "If in doubt, sit them out."

Understanding SCAT6 (and SCAT5 for Historical Context)

The SCAT6 (Sport Concussion Assessment Tool, 6th Edition) is the current internationally recognised tool for assessing suspected concussion in athletes aged 13 and over. It was developed following the 2022 Amsterdam International Consensus Conference on Concussion in Sport and published in June 2023. It's intended for use by trained healthcare professionals, ideally within the first 10–15 minutes after injury, and includes symptom evaluation, cognitive screening, and balance assessment components.

In terms of status, SCAT5 has been superseded, while SCAT6 is the current standard. Their basis differs too — SCAT5 was built on the 2017 consensus, while SCAT6 reflects the 2022 Amsterdam consensus. For use today, both may still be seen in practice, so familiarity with both is useful, though SCAT6 is recommended for current practice. And their key focus differs slightly: SCAT5 centred on symptom and cognitive screening, while SCAT6 offers refined screening with expanded memory testing.

Importantly, SCAT6 supports clinical decision-making but never replaces it — a normal score doesn't rule out concussion, and any suspected injury still requires careful clinical judgment and observation over time.

Red Flag Signs That Require Immediate Emergency Referral

Loss of consciousness, repeated vomiting, worsening headache, neck pain, seizures, limb weakness, unequal pupils, increasing confusion, slurred speech, and persistent drowsiness are all red flags requiring urgent emergency medical evaluation, not routine physiotherapy management.

Graduated Return-to-Play Protocol

The protocol progresses through six stages. Stage 1, relative rest for 24–48 hours, allows initial symptom settling. Stage 2, light aerobic activity, increases heart rate without provoking symptoms. Stage 3, sport-specific exercise, adds movement with no head impact risk. Stage 4, non-contact training, reintroduces coordination and cognitive load. Stage 5, full-contact practice, follows medical clearance where required. Stage 6, return to competition, marks full participation.

Athletes should only progress to the next stage once fully symptom-free at the current one, with any symptom recurrence prompting a return to the previous stage before trying again.

Role of the Sports Physiotherapist During Recovery

Sports physiotherapists monitor symptoms closely, assess balance and cervical spine function, deliver vestibular rehabilitation, and guide exercise progression through each return-to-play stage. They also communicate with treating doctors, educate athletes, coaches, and — for youth athletes — parents, and provide crucial support in return-to-play decision-making alongside the medical team.

Physiotherapy Rehabilitation After Concussion

Rehabilitation may include vestibular rehabilitation for dizziness and balance issues, cervical spine treatment where neck involvement contributes to symptoms, visual tracking exercises, and controlled aerobic exercise progressing toward functional and sport-specific training. Programmes are individualised, since concussion presentations and recovery timelines vary considerably between athletes.

Common Mistakes That Delay Recovery

Returning to play too soon, ignoring persistent symptoms, skipping medical review, excessive physical or cognitive exertion immediately after injury, poor communication between athlete and support staff, self-diagnosis, lack of follow-up, and inadequate monitoring all commonly delay full recovery and increase reinjury risk.

Why Sports Physiotherapists Need Concussion Training

Structured concussion education strengthens clinical reasoning, sharpens early recognition, and improves emergency decision-making on the field. It also supports safer rehabilitation planning, more confident return-to-play decisions, and stronger multidisciplinary collaboration with physicians — all of which directly improve athlete safety.

Practical Tips for Athletes, Coaches, and Physiotherapists

  1. Report symptoms honestly, even if it means missing a match
  2. Never hide or downplay a suspected concussion.
  3. Remove the athlete from play immediately if a concussion is suspected.
  4. Follow the staged return-to-play protocol without shortcuts.
  5. Monitor symptoms closely throughout recovery.
  6. Avoid rushing recovery to meet competition schedules.
  7. Educate teammates on recognising concussion signs.
  8. Prioritise sleep and rest during early recovery.
  9. Follow professional medical advice at every stage.
  10. Return to sport only once medically appropriate.

Frequently Asked Questions

What is concussion management in sports physiotherapy? It's the structured process of recognising, assessing, and rehabilitating a concussed athlete through monitored recovery and a graduated, medically guided return-to-sport programme.

How do physiotherapists assess a concussion? Physiotherapists use structured tools like SCAT6, symptom monitoring, balance testing, and cervical spine assessment, always working alongside physicians for medical clearance.

What is SCAT6? SCAT6 is the current internationally recognised concussion assessment tool for healthcare professionals, evaluating symptoms, cognitive function, and balance following suspected injury.

Is SCAT5 still used? SCAT5 has been superseded by SCAT6 in current practice, though understanding it remains useful for historical context and for comparing older assessment records.

How long does concussion recovery take? Most athletes recover within one to four weeks, though timelines vary significantly based on injury severity, individual factors, and adherence to graduated return-to-play protocols.

When can athletes return to sports after a concussion? Athletes can return only after progressing symptom-free through each stage of a graduated return-to-play protocol, with medical clearance where required.

What are the warning signs after a concussion? Warning signs include worsening headache, repeated vomiting, seizures, increasing confusion, slurred speech, and persistent drowsiness, all requiring urgent medical evaluation.

Can physiotherapy help concussion recovery? Yes, physiotherapy supports recovery through vestibular rehabilitation, cervical treatment, symptom monitoring, and structured, individualised return-to-sport progression.

Why should athletes never ignore concussion symptoms? Ignoring symptoms increases the risk of prolonged recovery and, if reinjured before healing, of disproportionately severe consequences from a second impact.

Why do sports physiotherapists need concussion training? Concussion training improves recognition, clinical reasoning, and safe return-to-play decision-making, strengthening athlete safety and confidence in high-pressure situations.

Conclusion

Concussion is a serious but manageable sports injury when recognised early and treated appropriately. Evidence-based assessment, structured rehabilitation, and close multidisciplinary collaboration remain the foundation of safe return-to-play decisions. As concussion guidelines continue to evolve, sports physiotherapists must keep updating their knowledge to protect the athletes in their care.
