Effects of 1 Hz Low-Frequency Repetitive Transcranial Magnetic Stimulation Combined with Scapulohumeral Training on Upper Limb Function in Stroke Patients

This study investigates the effects of scapulohumeral training combined with 1 Hz low-frequency repetitive transcranial magnetic stimulation (LF-rTMS) on muscle activation, muscle tone, and upper limb function in patients with stroke. Twenty stroke patients were divided into an experimental group that received LF-rTMS combined with scapulohumeral training and a control group that received sham-rTMS combined with scapulohumeral training. Intervention was provided five times a week for 50 min over six weeks. Muscle activation was assessed using electromyography, muscle tone was measured through MyotonPRO, and the upper-limb function was evaluated by manual function test (MFT). Electromyography and MyotonPRO results show statistically significant differences in the upper trapezius and anterior deltoid (p<0.05) and in the difference in the upper trapezius and biceps brachii (p<0.05), respectively, between the two groups. No statistically significant differences were observed in the MFT assessment (p>0.05). The 1 Hz LF-rTMS has a positive effect on upper limb muscle activation and muscle tone in patients with stroke. Through this, It is concluded that 1Hz low-frequency rTMS has a positive effect on improving upper limb muscle activation and muscle tone in stroke patients.
