Objective To investigate the impact of balance biofeedback training on plantar pressure and balance function in stroke patient with foot inversion.Methods A total of 60 patients with foot inversion after stroke were enrolled,which includ-ed 35 males and 25 females,aged 50-58 years old with mean age of 54.79 years old;disease duration was 79-92 days with mean duration of 87.76 days;33 cases with left hemiplegia and 27 with right hemiplegia;31 cases with cerebral infarction and 29 with cerebral hemorrhage.All of them were randomly divided into control group(n=30,performed comprehensive training)and experimental group(n=30,performed comprehensive training and balance biofeedback training).All of them were trained continuously for 8-week,5-day per week with 2 sessions each day lasting 60 minutes.Before treatment and 8-week after treatment,the plantar pressure and balance kinematics parameters were compared with the Footscan three-dimensional dy-namic plantar pressure gait analysis system of Tekscan,USA.Results There was no significant difference in medial-lateral pres-sure and contact area between 2 groups before treatment(P>0.05);after treatment,the medial pressure increased(P<0.05),and lateral pressure decreased(P<0.05)in 2 groups[before and after treatment in experimental group:medial pressure(150.18±96.30)N vs(175.70±99.95)N,lateral pressure(184.14±85.72)N vs(166.46±112.01)N;before and after treatment in control group:me-dial pressure(147.11±74.22)N vs(165.97±71.93)N,lateral pressure(230.13±93.73)N vs(223.57±114.75)N].The medial contact area was increased(P<0.05),and lateral contact area decreased in 2 groups(P<0.05)[before and after treatment in experi-mental group:medial contact area(26.75±12.07)cm2 vs(34.97±19.17)cm2,lateral contact area(45.79±21.57)cm2 vs(37.86± 21.99)cm2;before and after treatment in control group:medial contact area(39.28±22.25)cm2 vs(42.44±14.76)cm2,lateral con-tact area(45.74±22.66)cm2 vs(41.73±20.54)cm2],the changes of medial-lateral pressure and contact area in experimental group were more significant than those in control group(P<0.05).There was no significant difference in kinematic parameters before treatment between 2 groups(P>0.05).After treatment,the trajectory length,mean square error,maximum shaking diameter,total trajectory,offset length and envelope area on X and Y axes of 2 groups were significantly reduced(P<0.05),the speed and trajectory length per unit area were significantly increased(P<0.05).The improvement of balance kinematics parameters in experimental group was more significant(P<0.05).Conclusion It is demonstrated that balance biofeedback training could significantly im-prove the plantar pressure and balance function of stroke patient with strephenopodia.
