Concussion recovery is complex, but exercise can help

  • Low-intensity aerobic activity can help fast-track recovery from concussion
  • Complete rest is recommended in the first 24-48 hours post-concussion but then moderate activity is beneficial
  • Sleep hygiene is often impacted after a concussion and is important to get right
  • Low-intensity aerobic exercise can kick-start your recovery

    Early initiation of low-intensity aerobic exercise is recommended for athletes who have suffered a concussion, a leading strength and conditioning coach and physiotherapist says.

    Brooke Nairn, a strength and conditioning coach and physiotherapist based in Ireland, says current evidence suggests complete rest is no longer supported after a concussion.

    “[In terms of current evidence], nothing exists to support complete rest post-concussion, but high levels of cognitive and physical activity may also delay recovery. So we want to find a balance between strict rest and high-level activity,” Nairn said during her Science for Sport presentation titled ‘Concussion Rehab.’
    “Strict rest and ‘darkroom’ strategies are no longer recommended, as they are found to be outdated and ineffective. Complete rest increases risk of mental health challenges, social isolation, prolonged recovery, physical deconditioning, sleep irregularity.

    “Research supports early [within one week] initiation of [low intensity] aerobic exercise. Rest during [the first] 24-48 hours, followed by early, light physical activity below symptoms threshold, such as a 10-15 minute walk, is recommended for improving recovery.”

    While complete rest was not appropriate unless the symptoms were severe, Nairn said some activities should be minimised during the post-concussion period.

    “Avoid reading, video games, TVs, phones and highly visual activities like shopping trips and spectating at sports events,” she said. “As tolerated, audio books, soft music, slow walks, short phone calls, sitting/eating outside [are all acceptable].”

    Sleep is also a key part of the recovery process

    Sleep was another key area to focus on for post-concussion, Nairn said.

    “Sleep difficulty is a common complaint post-concussion – it can lead to protracted recovery and is linked to symptoms of anxiety, depression, slower rehab process,” she said.

    Nairn said there were several ways to improve sleep, including developing a sound bedtime ritual, sleeping in a dark, silent room, not eating too much before bed, reduced caffeine intake and minimal use of TVs or computers before bed.

    “Try to put all these elements in place,” she said.
