Rehabilitative effect of low—frequency rTMS combined FES on lower limb spasm and motor function in patients with subacute ischemic stroke / 心血管康复医学杂志

ABSTRACT

Objective:To explore rehabilitative effect of low—frequency (1Hz ,LF) repetitive transcranial magnetic stimulation (rTMS) combined functional electrical stimulation (FES) on lower limb spasm and motor function in pa—tients with subacute ischemic stroke (SAIS).Methods: A total of 92 SAIS patients with lower limb spasm and motor dysfunction hospitalized in our department were randomly divided into sham stimulation + FES group (sham stimu—lation group ,n＝45) and low—frequency rTMS + FES group (LF—rTMS group ,n＝47) ,both groups were continu—ously treated for three weeks .Lower limb motor function and spasm severity were assessed by Fugl—Meyer motor as—sessment (FMA) and modified Ashworth scale (MAS) respectively before and after treatment ,and motor evoked potential (MEP) was detected .Results: Compared with before treatment ,there was significant rise in FMA score , and significant reductions in MAS score and MEP in two groups after three—week treatment , P＝ 0.001 all ;com—pared with sham stimulation group ,there was significant rise in FMA score [16. 0 (13.0 ,23. 5 ) scores vs. 19. 0 (16.0 ,27.0) scores] ,and significant reductions in MAS score [1. 5 (1. 3 ,1.5) scores vs. 1. 0 (0. 5 ,1. 5) scores] and MEP [ (24.64 ± 0. 39) ms vs. (24.43 ± 0.31) ms] in LF—rTMS group after treatment , P＜0.05 or ＜ 0. 01 . Conclusion: Compared with sham stimulation + FES ,LF—rTMS + FES can more significantly improve lower limb spasm and motor function in patients with subacute ischemic stroke .
