| BackgroundCerebral infarction is the most common type,which causes most patients to lose the ability of daily life and aggravates the burden of family and society.About two-thirds of the survivors remained paralyzed to varying degrees.Intermediate frequency pulse electrotherapy is one of the modern rehabilitation methods,which can promote the functional recovery of affected limbs.However,there is no related research about the medium frequency pulse frequency electrotherapy stimulation at home and abroad.But the incidence rate of cerebral infarction is increasing gradually,but the increasing incidence of cerebral infarction,merge the paralysed patients more and more,so this study is to further research the most appropriate frequency,which can help in the clinical work in patients with hemiplegia to restore limb function,reduce the burden of the family and society.PurposeIn order to confirm the effect of medium frequency pulsed electrotherapy on the rehabilitation of limb function of hemiplegia patients with acute cerebral infarction and the optimal therapeutic stimulation range。MethodSixty-six patients with acute cerebral infarction in the Department of Neurology of the first people’s Hospital of Xinxiang were randomly divided into three groups: high frequency group,middle frequency group and low frequency group.YKL-B computer intermediate frequency therapeutic instrument was used for intermediate frequency pulse electrotherapy in each group.The low frequency group was given intermediate frequency pulse stimulation interval 20 Hz,and the medium frequency group was given intermediate frequency pulse electrical stimulation interval 31~40Hz.In the high frequency group,the interval of intermediate frequency pulse electrical stimulation was 41~50Hz.Each group was treated for 14 days.Before the beginning of the experiment and 14 days after treatment,more than two attending physicians collected the National Institutes of Health Stroke scale(NIHSS)scale and Brunnstrom staging to evaluate neurological impairment,the simplified Fugl-Meyer Motor function scale(FMA)scale was used to evaluate motor ability,and the modified Barthel Index(MBI)score was used to evaluate activities of daily living.14 days after treatment,the improved Rankin scale(mRS)score was used to predict the prognosis of the patients.During the treatment,EEG changes can be further monitored to evaluate the therapeutic effect.Apply SPSS23.0at the end of the experimentfor statistical analysis.Result1.There is no statistical significance in the general data of the three groups(P>0.05).2.There is no significant difference in NIHSS,Brunnstrom stage,FMA score and MBI score among the three groups before treatment(P>0.05).NIHSS score(8.76±3.93 vs9.64±4.63 vs 9.34±3.76),P=0.808;Brunnstrom staging(3.06±1.34 vs 2.86±1.25 vs3.10±1.33),P=0.822;FMA score(38.41±24.99 vs 34.05±22.41 vs 35.90±23.98),P=0.850;MBI score(47.06±22.29 vs 47.27±24.53 vs 46.25±21.33),P=0.989.3.After 14 days of treatment,Brunnstrom stage(4.76±0.83 vs 5.36±0.66 vs4.80±0.95)and FMA score(50.06±22.63 vs 56.86±20.77 vs 47.55 ±22.51)after 14 days of treatment in the three groups;MBI score(66.47±17.75 vs 72.05±21.97 vs 65.25±19.36)is higher than that before treatment(P=0.000),NIHSS score(6.53± 2.74 vs 5.55±3.36 vs7.10±3.24)is lower than that before treatment.P=0.000,the difference before and after treatment is statistically significant(P<0.05).4.After 14 days of treatment,there are significant differences in scores of various scales between the low frequency group and the medium frequency group before and after treatment: ⊿ NIHSS(-2.23±1.78 vs-4.09±2.30),⊿ Brunnstrom(1.70±1.10 vs2.50±1.10),⊿ FMA(11.64±6.61)22.81±10.14),P<0.05;There is no significant difference between the low frequency group and the high frequency group before and after treatment:⊿NIHSS(-2.23±1.78 vs-2.25±0.91),⊿Brunnstrom(1.70±1.10 vs1.70±0.97)and⊿FMA(11.64±6.61 vs 11.65±7.80),⊿MBI(19.41±10.28 vs 19.00±7.71),P>0.05;there is statistically significant difference between the medium frequency group and high frequency group before and after treatment: ⊿ NIHSS(-4.09±2.30 vs-2.25±0.91),⊿ Brunnstrom(2.50±1.10 vs 1.70±0.97),⊿ FMA(22.81±10.14vs11.65±7.80),⊿MBI(24.77±7.78 vs 19.00±7.71),P<0.05.ConclusionThe intermediate frequency pulse electrotherapy has obvious effect on the recovery of limb function in patients with acute cerebral infarction,and the medium frequency pulsed electric stimulation range(31~40 Hz)has the best effect,which has very important clinical significance in helping the rehabilitation of patients with cerebral infarction hemiplegia complicated with communication disorders. |
