Abstract
This study was to investigate effects of NMES with 1 Hz low-frequency repetitive transcranial magnetic stimulation
(LF-rTMS) applied to unaffected cerebral cortex on muscle activities, tone, and motor function of upper
limb (UL) in stroke patients. 16 patients were randomly divided into two groups, and experimental group (EG)
was subjected to 1 Hz LF-rTMS and neuromuscular electrical stimulation (NMES). In control group (CG),
Facilitation of hand intrinsic muscles and NMES were performed. It was evaluated using electromyography
(EEG), MyotonePRO, and Fugl-Meyer assessment (FMA). As a result, there were significant differences on
EMG of the anterior deltoid, triceps brachii (TB), MyotonePRO, and FMA in the EG. CG showed a significant
difference in EMG of TB. Between groups, there was a significant difference in the biceps brachii and TB. It’s
thought that 1 Hz LF-rTMS and NMES can have a positive effect to improve muscle activity and UL in stroke
patients.
