Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

A prospective, multi-center, randomized, sham-controlled, blinded study combining active Nexstim NBS-guided 1Hz rTMS or sham-rTMS targeting the healthy hemisphere with standardized task oriented rehabilitation will be conducted in patients with post-stroke motor impairment of the upper limb. The therapy will be provided for 6 weeks and primary outcome assessed 6 months later.
