The walking ability of hemiplegic patients is crucial for their future return to family and society, and insufficient dorsiflexion of the ankle joint often seriously affects the walking ability of the patients, our department strengthens the dorsiflexion function of the ankle joint through a variety of methods, and the present study compares the effects of acupuncture and myoelectric biofeedback on the walking ability of the lower limbs after strengthening the training of the ankle joint, respectively, through scientific statistical analysis. Zhang Wei, Rehabilitation Center, The First Affiliated Hospital of Henan College of Traditional Chinese Medicine 1 Data and Methods 1.1 Clinical data 75 patients with hemiplegia who underwent rehabilitation treatment for stroke in our department from January 2010 to December 2010 were selected, and the diagnosis was in accordance with the diagnostic criteria formulated by the Fourth National Conference on Cerebrovascular in 1996[1], and the diagnosis was confirmed to be cerebral infarction or cerebral hemorrhage by CT or MRI examination of the head, and the onset was within 3 years. or cerebral hemorrhage, and the onset of the disease was within 3 months, and there was no serious cardiopulmonary, hepatic or renal insufficiency, as well as cognitive impairment and auditory comprehension disorder. Seventy-five patients were randomly divided into acupuncture group, physiotherapy group and control group by lottery, 25 cases in each group, and the difference of general information of the three groups was not significant by statistical analysis (P>0.05). Table 1 Comparison of the general information of patients in two groups Groups Number of cases Sex (cases) Duration of disease (days) Cerebral hemorrhage (cases) Cerebral infarction (cases) Mean age (years) Male and female Acupuncture group 25151020131255.4±(11.3) Physiotherapy group 2516921141156.1±(12.8) Control group 25141120131256.3±(12.4) 1.2 Methods All three groups of patients after the stabilization of the condition all receive exercise re-learning technology [2] based conventional exercise therapy training and occupational therapy, and with Chinese medicine fumigation, equipment training and other methods, the above treatment once a day, 40min/time, 6 times/week, a total of 6 weeks of treatment. In the acupuncture group, acupuncture was added once a day on the basis of the above treatment, and the specific acupuncture points were: Thigh Pass, Fubu, Yanglingquan, Ashigaru, Upper Juxu, Jiekou, Lower Juxu, Fenglong, Xiexi, Sanyinjiao, Taichong, and the lumbar spine pinch point, and the operation method was: Ashigaru and Sanyinjiao were used with the tonic method, and the rest of the acupuncture points were used with the flat tonic method and flat cathartic method. Physiotherapy group in the control group on the basis of the affected side of the electromyography biofeedback (EMGBF) treatment, using WOND2000F-1 multifunctional neurological rehabilitation diagnostic and treatment system, the specific method is as follows: in the quiet treatment room, the patient takes a sitting position, the first treatment, should be explained to the patient’s therapeutic instrument’s working principle, the precautions, clean the skin with an alcohol cotton ball, will be positive and negative stimulating electrode sheet pasted on the affected limb tibialis anterior muscle belly, the reference electrode placed on the tibialis anterior muscle. The positive and negative stimulating electrode sheets are attached to the belly of the tibialis anterior muscle of the affected limb, and the reference electrode is placed in the center, but the 3 electrodes do not touch each other, and the unidirectional wave is selected with a frequency of 45-50Hz, a wave width of 200μs, a stimulation time of 10s, an intermittent interval of 10s, and the mode of automatic triggering and adjustable intensity of 0-40mA is selected. The therapist encouraged the patient to dorsiflex the ankle joint, and recorded the highest EMG signal as the baseline. When the patient’s EMG signal exceeded the baseline, the instrument would send out the commands of stimulation, maintenance, and rest in sequence, and the therapist should give the corresponding prompts in different commands, and when the patient’s spontaneous EMG signal exceeded the threshold, the instrument would automatically adjust the threshold upward when the patient contracted next time, and the threshold could be raised according to the patient’s tolerance level during the treatment. During the treatment, the threshold size can be adjusted according to the patient’s tolerance level and the patient’s fatigue level, and the treatment time is 20 min/times.1.3 Assessment criteria Before and after 6 weeks of rehabilitation training, the three groups of patients were assessed by the Fugl-Meyer Assessment (FMA) to evaluate the motor function of the lower limbs, the 10m walking time and functional ambulation grading (functional ambulation), and the 10m walking time and functional ambulation grading (functional ambulation). Walking ability was assessed by the functional ambulation category (FAC) [4]. All assessments were done by one therapist.1.5 Statistical analysis One-way analysis of variance (ANOVA) was performed using the spss17.0 software analysis system, and the comparative parameter: LSD, with P0.05 as the significance of the difference.2 ResultsBefore the treatment, there was no significant significance of the difference between the FMA, 10m walking time, and FAC of the three groups of patients (P>0.05); after the 6-week rehabilitation, the patients of the three groups had no significant difference in FMA, 10m walking time, FAC, and FAC. FMA, 10 walking time, and FAC were significantly improved compared with the pre-training period, and the difference was significant (P0.05); after the rehabilitation treatment, the results of the three ratings of the acupuncture group and the physiotherapy group were significantly different from the control group (P0.05); the comparison of the three ratings of the physiotherapy group and the acupuncture group was also significant (P0.05), see Table 2.

The ankle joint is a fine-tuning hub for human walking posture and stability, and whether ankle dorsiflexion can occur or not is extremely important for lower limb motor function and gait [6]. The lack of ankle dorsiflexion is a very important factor in walking difficulties, but ankle training tends to lag behind in the rehabilitation process of the whole lower limb, and intensive training is needed in order not to affect the walking ability of the whole lower limb. Some studies have proved that early induction of ankle dorsiflexion function can effectively mobilize the brain tissue storage cell function, induce the completion of movement type and coordination training in the cerebral cortex motor area, shorten the cycle of co-motor phase (Brunnstrom III), and promote further recovery of lower limb’s motor function [7], but there are many methods to restore ankle function, and our department is more commonly used acupuncture and EMGBF. Through experiments we can understand the difference between the two methods in terms of their ability to strengthen the ankle joint and their effect on the walking ability of the lower limb. Acupuncture and moxibustion are the treasures of traditional medicine in China, and are widely used in the treatment of stroke. Some studies have found that acupuncture and moxibustion not only have the effect of harmonizing qi and blood and dredging the meridians, but also stimulate the human cerebral cortex to generate electrical activity and enhance the sensory feedback of the affected limb to the brain, and the use of different needles can also play a role in triggering the muscle tone or alleviating the muscle tone, and promote the recovery of hemiplegic limb function [8].EMGBF As a new therapeutic method developed in recent years based on the theory of central nervous system plasticity [9], it is now widely used, and literature has shown that EMGBF has a significant effect on improving foot drop and enhancing ankle dorsiflexion in stroke patients, thereby promoting normal gait and restoring the patients’ walking ability [10]. The results of this study showed that after 6 weeks of rehabilitation training, the FMA, 10 walking time, and FAC of patients in the acupuncture group and the physiotherapy group were significantly improved compared with the pre-training as well as the control group, and the difference was significant, while the effect of patients in the physiotherapy group was better than that of the acupuncture group. The mechanism of action of acupuncture and EMGBF is different, acupuncture is through dredging the meridians and thus restoring the patient’s function, EMGBF is based on the theory of brain plasticity, the combination of neuromuscular electrical stimulation and electromyographic signals constantly stimulate the sensory-motor cortex, subcortical nuclei, awakening the responsive motor cells, including nerve outgrowths and activation of synapses, thus contributing to the recovery of locomotion [11], but the two through the limb peripheral nerve stimulation feedback to the CNS is the same mechanism. In the treatment process, the patient’s compliance with acupuncture is slightly poor, mainly because the pain of acupuncture is obvious, and many patients are bored and resistant because of this, EMGBF is relatively easy to be accepted by the patient, EMGBF amplifies and then outputs the patient’s weak electromyographic signals, and at the same time provides intuitive feedback to the patient through the monitor, so that the patient can participate in the treatment well, thus enhancing the desire and confidence in recovery [ 12]. This study shows that on the basis of conventional rehabilitation training methods, plus acupuncture or EMG biofeedback can better strengthen the dorsiflexion of the ankle joint, thus promoting the recovery of motor function of the lower limb, while EMG biofeedback is more effective than acupuncture.
