In 40 seconds
Concussion in rugby is well-known and well-managed with graded return-to-play protocols (RFU stage system). Most concussions resolve within 1–3 weeks. The 10–15% with persistent post-concussion symptoms can benefit from PEMF therapy targeting the underlying neuroinflammation. Always alongside rugby's mandatory medical pathway, never instead of stand-down protocols.
Quick facts
- Resolution timeline: Most 1–3 weeks
- Persistent symptoms: 10–15% beyond 4 weeks
- PEMF role: Targets neuroinflammation, supports recovery in persistent cases
- Always with: RFU stand-down + medical clearance pathway
- Never: Replace mandatory rest periods
Why this injury happens in this sport
Rugby concussions arise from contact with another player, the ground, or the ball. The British Journal of Sports Medicine has specifically called out persistent post-concussion syndrome as an area needing better treatment options.
Recovery and return to sport
PEMF use is for the persistent-symptom group, not acute. RFU stand-down is non-negotiable. After medical clearance, if symptoms persist, PEMF 2× per week for 6–8 weeks alongside graded exercise (Buffalo Concussion Treadmill Test guidance) and vestibular rehab where indicated.
Contraindications
Hard exclusions — do not have PEMF if any apply:
- Pacemaker, implantable cardioverter-defibrillator (ICD), or any cardiac electronic device
- Cochlear implant or other implanted electronic hearing device
- Spinal cord stimulator, deep-brain stimulator, vagus nerve stimulator
- Intrathecal pump or implanted drug pump
- Insulin pump (continuous glucose monitors are usually fine — confirm with the clinic)
- Active infection at the treatment site
- Pregnancy — when treatment would be over the abdomen, lumbar spine, or pelvis
Discuss with your GP or specialist before booking if any apply:
- Active malignancy or recent cancer history (oncologist clearance required)
- History of seizures or epilepsy
- Multiple sclerosis or other neurological condition under specialist care
- Anticoagulant therapy (PEMF itself does not thin blood, but bruising risk if local circulation is already compromised)
- Children under 14 (most UK clinics will not treat under-18s without paediatric specialist input)
- Recent surgery within the last 14 days at the treatment site (confirm with surgeon)
NOT contraindications — these are commonly misunderstood:
- Plates, rods, screws and other passive metal orthopaedic hardware
- Dental implants and dental crowns
- Joint replacements (hip, knee, shoulder)
- IUDs (copper or hormonal)
- Tattoos and piercings (jewellery should be removed for the session)
Specific to this condition: pacemakers, defibrillators, cochlear implants, insulin pumps, electronic implants; active malignancy without specialist clearance; pregnancy (over the abdomen); active infection; epilepsy without GP clearance.
Frequently asked questions
Can I have PEMF during my RFU stand-down?
Discuss with the rugby medical team. Standard protocol focuses on relative rest in early phase; PEMF use in this window is decided case-by-case with clinical input.
Will it help my brain fog?
Many post-concussion patients report meaningful brain fog improvement with regular PEMF, particularly when combined with sleep optimisation and graded activity.
What about CTE?
Chronic traumatic encephalopathy is a serious concern in elite rugby. PEMF is not a CTE treatment. Acute concussion management remains the priority.
