A multi-institutional study using our protocol of low-frequency repetitive transcranial magnetic stimulation (rTMS) and intensive occupational therapy (OT) showed significant improvement of motor function of the affected upper limb in poststroke patients. The response to the treatment was not influenced by age or time after stroke onset. Our protocol is a safe, feasible, and potentially useful neurorehabilitative intervention for upper limb hemiparesis after stroke. The extent of the improvement seems to be influenced by the baseline severity of upper limb hemiparesis. The results suggest that patients with Brunnstrom stage 4 or 5 upper limb hemiparesis are best suited for this protocol. Botulinum toxin type A (BoNT-A) has been reported to be an effective treatment for limb spasticity after stroke. However, the spasticity reduction after BoNT-A injection alone does not ensure an improvement in the active motor function of the affected limb. Our proposed protocol of a BoNT-A injection, followed by home-based functional training seems to have the potential to improve the active motor function of the affected upper limb after stroke.
