Abstract:
Objective:To document any effect of combining transcranial magnetic stimulation (rTMS) with peripheral magnetic stimulation (rPMS) to relieve shoulder pain in hemiplegic stroke survivors.Methods:Sixty hemiplegic stroke survivors with shoulder pain were randomly divided into a Central Group ( n=20), a Peripheral Group ( n=20), and a Combined Group ( n=20). In addition to routine pharmacological intervention and rehabilitation training, the Central Group received 10Hz rTMS over the M1 area of the affected hemisphere, the Peripheral Group received 20Hz rPMS at Erb′s point of the affected limb, while the Combined Group received rTMS followed by rPMS. Before as well as after 2 and 4 weeks of treatment, all were assessed using a numerical pain intensity rating scale (NRS), for passive range of motion (PROM) of the shoulder joint, and using the Fugl-Meyer upper extremity assessment (FMA). Results:Before the treatment there were no significant differences among the 3 groups. After 2 weeks there was significant improvement in the average shoulder PROM and FMA scores, and a significant decrease in the average NRS ratings. After 4 weeks there was continued significant improvement. After 2 and 4 weeks, the Combined Group gave significantly lower NRS ratings than the others and had greater average shoulder PROM improvement. The average FMA score of the Combined Group (36.10±13.32) after two weeks was significantly better than those of the Central and Peripheral groups. However, no significant differences were found between the Central and Peripheral Groups in the other measurements.Conclusions:Both rTMS and rPMS can relieve shoulder pain and promote the recovery of motor function, with superior synergistic effects observed in their combined application.
