Abstract:
Objective:To observe and explore the therapeutic effect of ankle brain computer interface therapy based on motor imagination on the rehabilitation of lower limb motor function and balance ability in stroke patients with hemiplegia.Method:Total 40 patients with hemiplegia after stroke were randomly divided into an experimental group and a control group using a random number table method,with 20 people in each group.Both groups received con-ventional clinical medicine and conventional rehabilitation treatment.The control group was given additional an-kle stretching robot training,once a day,30min/times,for 2 weeks.The experimental group was given addition-al foot and ankle brain-computer interface treatment based on movement imagination,once a day,30min/time,for 2 weeks,before treatment.After 2 weeks of treatment(after treatment),the Hoggan Micro FET3 tester was used to measure the back flexion muscle strength and active joint range of motion(AROM);Clinical evaluation was conducted using the modified Ashworth muscle tension scale(MAS),Fugl-Meyer lower limb movement score(FMA-LE),Berg balance scale(BBS),functional walking scale(FAC),and 6-minute walk test(6MWT).Result:Three patients in the control group and three patients in the experimental group dropped off.After 2 weeks of treatments,significant improvements were observed on the dorsiflexion muscle strength,dorsiflexion AROM,FMA-LE,BBS,FAC,and 6MWT(P<0.05)in the two groups.The MAS of the experimental group improved significantly(P<0.05)compared with that before treatment.After treatment,there were significant differ-ences in AROM,FMA-LE,and BBS between the two groups(P<0.05).Conclusion:Motor imagery-foot and ankle brain-computer interface therapy can effectively improve lower limb motor function and balance in stroke hemiplegic patients.
