There does not appear to be any reason why you cannot use a TENS machine if you have epilepsy. We have checked this out with a consultant neurologist in the past, to establish if patients with epilepsy can safely use TENS machine and his answer was “Yes!”. Electrical stimulation is not only safely used in TENS machine but is in fact also used to treat intractable epilepsy. However, if you are unsure please contact you medical advisor or Epilepsy Specialist Nurse for further guidance.
