Methods Sixty children with CP were randomly divided into a scalp acupuncture combined with rehabilitation training group （group SA＋RT） and a rehabilitation training group （group RT） with 30 cases in each group. Conventional rehabilitation therapy and balance training were applied in group RT, and scalp acupuncture at close acupoints in the parietal region and sub-occipital region was added besides rehabilitation training in group SA＋RT. Balance functions were evaluated by using Berg rating scale, and abilities of daily living were estimated by using rating scale for activities of daily living （ADL）. Results After treatment, both Berg scores for balance and ADL scores were significantly improved in both groups （all P0.05）, and the improvement in group SA＋RT was more obvious than that in group RT （ both P0.05）. Conclusion Combination of scalp acupuncture at close acupoints with rehabilitation training is superior to simple rehabilitation training in improving balance functions and activities of daily living in children with cerebral palsy.展开更多

The intervention group received cognitive-motor dual task training on the basis of routine rehabilitation training, and the training time and frequency were the same for the two groups. The intervention training lasted for 8 weeks. Changes in patients' balance function and ADL were assessed before and after 8 weeks of intervention, including Berg Balance Scale, Fugl-Meyer Balance Scale and ADL score. Changes in scores of each test were recorded for statistical analysis. Results: after the end of the experiment, intervention group 2 and control group all completed the study 8 weeks after intervention, intervention group and control group showed significant improvement in the three tests compared with before intervention. When standing up while sitting and standing without support, the Berg balance scale score of intervention group was significantly higher than that of control group. Fugl-Meyer and ADL scores of the intervention group under the dual task were significantly higher than those of the control group. After three tests, statistical analysis showed that the differences were statistically significant (P <0.05). Conclusion: the cognitive-motor dual task training can improve the balance function and ADL of stroke patients, and the dual task training combined with the routine rehabilitation training is more conducive to the recovery of balance function of patients, so as to improve the ADL.
文摘Objective: to use early rehabilitation treatment for the patients with acute stroke hemiplegia, to observe and analyze its impact on the upper and lower limb function recovery and daily life ability. Methods: in June 2021-June 2022 for intercept research time interval, a total of 60 cases of acute stroke hemiplegia, random principle specification grouping, control group received 30 cases of routine treatment, observation group received 30 cases of early rehabilitation treatment, around the upper and lower limb function assessment score, daily life ability evaluation score, balance function, cognitive function scale evaluation score and complication rate data line to compare. Results: before the treatment work, the evaluation results, daily life ability, balance function, and cognitive function evaluation results showed no difference (P> 0.05), and the results were higher (P <0.05);for the complication rate, the observation group showed lower results (P <0.05). Conclusion: for acute stroke cases, early rehabilitation treatment, which can improve the function of upper and lower limbs, strengthen their living ability, balance function and cognitive function, and prevent complications in patients, which is worthy of clinical application.
文摘Objective:To explore the effects of functional electrical stimulation and functional mid frequency electrical stimulation on lower limb function and balance function in stroke patients.Methods:20 cases of stroke patients with foot drop after admission were randomly divided into the observation group and the control group,10 cases in each group.On the basis of the two groups of patients,the observation group used the gait induced functional electrical stimulation to stimulate the peroneal nerve and the pretibial muscle in the observation group.The control group used the computer medium frequency functional electrical stimulation to stimulate the peroneal nerve and the anterior tibial muscle for 2 weeks.Before and after treatment,the lower extremity simple Fugl-Meyer scale(FMA),the Berg balance scale(BBS)and the improved Ashworth scale were evaluated respectively,and the comparative analysis was carried out in the group and between the groups.Results:After 2 weeks of treatment,the scores of FMA and BBS in the two groups were significantly higher than those before the treatment(P<0.05),and the scores of FMA and BBS in the observation group were higher than those in the control group(P<0.05),and the flexor muscle tension of the ankle plantar flexor muscle of the observed group was lower than that of the control group(P<0.05).Conclusions:Exercise therapy combined with gait induced functional electrical stimulation or computer intermediate frequency functional electrical stimulation can significantly improve lower limb function and balance function in patients with ptosis,and the therapeutic effect of functional electrical stimulation combined with gait is better.

文摘It is difficult to determine the effective reservoir rock compressibility,aquifer volume and water influx of high pressure and ultra-high pressure gas reservoirs,so when the traditional apparent reservoir pressure and cumulative gas production curve extrapolation method and its modified version are used to calculate the initial gas in-place of such gas reservoirs,the calculation accuracy is lower.The material balance equation in the form of power function for such gas reservoirs was established based on Gonzalez method to improve the accuracy and reliability of reserve evaluation.Then,based on 20 high pressure and ultra-high pressure reservoirs that had been developed abroad,the empirical value of the power exponent was defined,and the influences of the depletion degree of apparent reservoir pressure and the degree of reserve recovery on the reliability of reserve calculation were analyzed.Besides,the critical value of the key parameter affecting the reliability of reserve evaluation(depletion degree of apparent reservoir pressure)was determined and compared with the critical value of the two-linear trends.Finally,an example calculation was carried out.And the following research results were obtained.First,the empirical value of the power exponent calculated using the material balance method in the form of power function is 1.02847,with an upper limit of 1.11567.Second,the depletion degree of apparent reservoir pressure corresponding to the inflection point of the classical two-linear trends ranges from 0.14 to 0.38 with an average of 0.23,while that corresponding to the extrapolation point of the second straight line is between 0.23 and 0.50 with an average of 0.33,and the corresponding degree of reserve recovery is in the range of 33%-65%with an average of 45%.Third,the reserves of such high pressure gas reservoirs calculated with this new method has an error rate less than 10%if the depletion degree of apparent reservoir pressure is greater than 0.33.In conclusion,for such high pressure gas reservoirs and the stress-sensitive fractured gas reservoirs,the material balance method in the form of power function proposed in this paper can avoid the uncertainty parameters(e.g.effective reservoir rock compressibility,aquifer volume and water influx)and it is advantageous with simple calculation process,better practicability and small error.
