Objective: To investigate the effects of low frequency transcranial magnetic stimulation (LF-rTMS) combined with motor imagery (MI) on upper limb motor function during stroke rehabilitation.Background: Hemiplegic upper extremity activity obstacle is a common movement disorder after stroke.Compared with a single intervention, sequential protocol or combination of several techniques has been proven to be better w insta saree for alleviating motor function disorder.
Non-invasive neuromodulation techniques such as repetitive transcranial magnetic stimulation (rTMS) and motor imagery (MI) have been verified to augment the efficacy of rehabilitation.Methods:Participants were randomly assigned to 2 intervention cohorts: (1) experimental group (rTMS+MI group) was applied at 1 Hz rTMS over the primary motor cortex of the contralesional hemisphere combined with audio-based MI; (2) control group (rTMS group) received the same therapeutic parameters of rTMS combined with audiotape-led relaxation.LF-rTMS protocol was conducted in 10 sessions over 2 weeks for 30 min.
Functional measurements include Wolf Motor Function Test (WMFT), the Fugl-Meyer Assessment Upper Extremity (UE-FMA) subscore, the Box and Block Test (BBT), and the Modified Barthel index (MBI) were conducted at baseline, the second week (week 2) and the fourth week (week 4).Results: All assessments of upper limb function improved in both groups at weeks 2 and woody creek summer gin 4.In particular, significant differences were observed between two groups at end-intervention and after intervention (p < 0.
05).In these findings, we saw greater changes of WMFT (p < 0.01), UE-FMA (p < 0.
01), BBT (p < 0.01), and MBI (p < 0.001) scores in the experimental group.
Conclusions: LF-rTMS combined with MI had a positive effect on motor function of upper limb and can be used for the rehabilitation of upper extremity motor recovery in stroke patients.
