title: Biofeedback therapy of essential blepharospasm.
abstract: Eight patients with essential blepharospasm were given five consecutive sessions of electromyogram biofeedback from cutaneous electrodes placed over the frontalis muscle. Four of the eight patients demonstrated a 60% or greater reduction in blepharospasm frequency. Posttreatment electromyogram significantly predicted improvement of blepharospasm. These data suggest that electromyogram biofeedback may provide a therapeutic alternative to the treatment of this disabling condition.
