Support activation, then practise the task
Neuromuscular electrical stimulation (NMES) may assist selected weak muscles to contract. EMG biofeedback may show a patient when voluntary activation occurs. Possible goals include ankle control, shoulder support, wrist or hand activation and improved awareness of movement.
Stimulation alone does not teach walking, reaching or self-care. It should be paired with task-specific rehabilitation and reviewed against functional outcomes.
Not every weak muscle is suitable for stimulation
Selection considers the stroke pattern, sensation, skin, joint range, spasticity, cognition, communication, implanted devices and the patient’s ability to participate. Electrode placement and dose are individualised.
Track function instead of contractions alone
Useful outcomes can include safer foot clearance, improved reaching, better hand opening, easier transfers, reduced shoulder discomfort or greater participation in daily tasks. Treatment is changed or stopped if it does not support a meaningful goal.
Frequently asked questions
Is NMES the same as TENS?
No. NMES aims to activate muscle. TENS is commonly used for sensory-level symptom modulation, although device settings and terminology vary.
Can NMES cure paralysis after stroke?
No cure can be promised. It may support selected motor goals when combined with active rehabilitation.
Can it be used with a pacemaker?
Implanted electronic devices require specific medical and device-safety review before electrical stimulation.
