Lower-limb motor recovery is less studied than upper-limb. The Zhang 2024 meta-analysis of rTMS for lower-extremity in stroke confirmed improved gait velocity. Cerebellar rTMS is an emerging target. The interhemispheric-competition model is less clean for leg muscles (which have more bilateral cortical representation), so contralesional M1 protocols may need adaptation. Standard NICE NG236 pathway — physiotherapy, treadmill training (including body-weight-supported), functional electrical stimulation, robot-assisted gait training — remains first-line. rTMS sits as research adjunct. No UK NHS commissioning for rTMS in leg recovery. Consumer PEMF mats have no leg-recovery RCT.
Quick facts
- Zhang 2024 meta: Improved gait velocity in stroke patients
- Most-studied target: Affected-leg M1 (less clean interhemispheric model than arm)
- Emerging target: Cerebellar rTMS
- Standard pathway: Physio, treadmill (BWS), FES, robot-assisted gait
- UK access: Research trial only
- Consumer PEMF in leg recovery: No completed RCT
Why leg-recovery rTMS is less developed than arm
Leg motor recovery after stroke is less studied with rTMS than arm recovery for several reasons. Lower-limb muscles have more bilateral cortical representation than hand/finger muscles, so the contralesional-suppression strategy that works so well for the arm is less directly applicable. The M1 leg area is also further from the scalp than the M1 hand area, making focal stimulation harder.
Despite this, Zhang 2024's meta-analysis confirmed positive gait-velocity effects across pooled lower-extremity rTMS trials. Protocols vary — HF over affected M1 is most common; cerebellar rTMS is an emerging direction with several recent positive pilots.
Standard UK leg-recovery pathway (per NICE NG236) is physiotherapy-led: gait training, treadmill training (with body-weight support where needed), functional electrical stimulation, robot-assisted gait, balance training. These have stronger and larger evidence than current rTMS protocols for leg recovery. rTMS sits as research adjunct.
Frequently asked questions
Can rTMS improve my walking after stroke?
Zhang 2024 meta-analysis confirmed improved gait velocity with rTMS. Effects are modest at group level. UK access via research trial only.
Why is leg rTMS less studied than arm?
Lower-limb muscles have more bilateral cortical representation. M1 leg area is deeper, harder to focal-stimulate. The interhemispheric model that drives arm-rTMS is less applicable.
What is cerebellar rTMS?
Emerging target — stimulating the cerebellum (via posterior fossa coil placement) appears to modulate gait circuits. Several pilot trials underway.
Can a PEMF mat help my leg recovery?
No completed RCT. Standard rehabilitation remains evidence-based.
What about functional electrical stimulation?
FES has stronger evidence than rTMS for stroke leg recovery in NICE NG236. Often combined with standard physio.
Does treadmill training with body-weight support work?
Yes — it has Cochrane-level evidence and NICE NG236 support. Standard NHS-available rehabilitation.
Is rTMS for leg recovery on the NHS?
No. NHS does not commission rTMS for stroke leg recovery.
How long after my stroke can I try rTMS for legs?
Most published trials enrol subacute (1-6 months) patients. Chronic-phase rTMS evidence in legs is small but exists.
