Methods Thirtysix hemiplegic patients were included and were divided into two groups randomly, including a treatment group and a control group. They were treated with the same drugs and the routine rehabilitation therapy while the patients in the treatment group still received the electromyographic biofeedback therapy additionally. Results After three courses of treatment, the patients in the treatment group had better active range of movement (AROM) of extension of wrist joint and also higher electromyographic (EMG) threshold of maximum contraction of muscle than the patients in the control group (Plt;0.001). Conclusion The electromyographic biofeedback therapy has good effect on improving the function of the wrist of hemiplegic patients after stroke.
Objective To explore the status of smoking and passive smoking of the population with the high risk of stroke in the community and their attitude towards smoking control. Methods In March 2015, under the direction of Stroke Screening and Prevention Projection, the residents with the high risk of stroke were sought out in Longfeng Community, Suining City, Sichuan Province. And then their status of smoking and passive smoking and their attitude towards smoking control was investigated by Passive Smoking Questionnaire for Adults from National Smoking Control Office. Results A total of 354 residents with the high risk of stroke were sought out, in whom 152 (42.9%) were smokers, and the smoking rate of males (70.1%) and females (1.4%) was significantly different (P<0.001). Those aged 40-49 had the highest smoking rate (55.0%), followed by those aged 50-59 (51.7%), and smokers of the two age groups accounted for 73.0% of all smokers. There was significant difference in smoking rate among different age groups (P<0.001). The smoking rate of those with a lower education level of primary school (57.9%) was the highest, and there were significant differences in smoking rates among the population with different education levels (P<0.001). The smoking rate of the solitary (95.7%) was higher than that of the non solitary (34.9%) (P<0.001). In 202 non-smokers, 67 (33.2%) was suffered from passive smoking, and the rate of passive smoking was 31.3% in males and 62.3% in females with a significant difference (P<0.001). The proportion of the female non-smokers against passive smoking (84.1%) was higher than that of the male non-smokers (57.8%). According to the participants report, 79.9% of participants approved completely non-smoking in hospital, school and public transport, 66.4% approved non-smoking in the office and traffic station, and only 10.2% approved non-smoking in the restaurants. Conclusions The rates of smoking and passive smoking among the population with the high risk of stroke are high, and most of the population are supportive to smoke prohibition in public places except restaurants. The population with a low cultural level is short of smoking harm knowledge.
Objective To assess the clinical efficacy of statins for preventing stroke recurrence. Methods We searched The Cochrane Library, PubMed, EMbase, CBM, CSJD, and CJFD for randomized controlled trials on the use of statin drugs to prevent stroke recurrence (up to May 10, 2008), and manually searched key Chinese magazines in the related fields. Two reviewers extracted data independently using a designed extraction form. The quality of included trials was evaluated according to the Cochrane handbook 4.12. RevMan 5.0 software was used for data analysis. Results Six randomized controlled trials involving 9,675 patients were identified. The results of meta-analysis showed that there was no statistical difference in stroke recurrence rate (RR=0.94, 95%CI 0.84 to 1.04, P=0.21) and fatal stroke occurrence (RR=0.77, 95%CI 0.48 to 1.25, P=0.30) between statins and placebo groups, but a significant difference was found between the two groups in transient ischemic attack occurrence (RR=0.80, 95%CI 0.69 to 0.92, P=0.002). Conclusion Current evidence indicates that statin drugs have no superiority to prevent stroke recurrence and fatal stroke occurrence, but can prevent transient ischemic attack.
Objective To evaluate whether respiratory training can improve motor function, exercise endurance, and activity of daily living (ADL) in stroke patients. Methods The randomized controlled trials of the effects of respiratory training on motor function, exercise endurance, and ADL in stroke patients were searched in PubMed, Embase, Google Scholar, China National Knowledge Infrastructure, Wanfang, and VIP Database. The search date was from the establishment of each database to December 2018. The control group received routine rehabilitation, medical treatment or other interventions, and the trial group added respiratory training on that basis. Outcome measures included the Fugl-Meyer Assessment (FMA), the 6-minute walk test (6MWT), and the modified Barthel Index (BI). The literature was independently screened by two investigators according to the inclusion and exclusion criteria, and the quality of the included articles was evaluated using the Physiotherapy Evidence Database scale and Cochrane Library systematic review criteria. Statistical analysis was performed using RevMan 5.3 software. Results A total of 11 articles with 741 stroke patients were included. Meta-analysis showed that in the trial group the exercise endurance [mean difference (MD)=41.50 m, 95% confidence interval (CI) (7.63, 75.37) m, P=0.02], ADL [MD=9.97, 95%CI (3.99, 15.96), P=0.001], and motor function [MD=8.00, 95%CI (1.29, 14.70), P=0.02] were improved compared with those in the control group. Subgroup analysis showed that after 8-10 weeks of intervention, BI of the trial group was higher than that of the control group [MD=25.37, 95%CI (16.49, 34.25), P<0.000 01]; after 8 weeks and 12 weeks to 3 months of intervention, FMA of the trial group was higher than that of the control group [ after 8 weeks: MD=20.40, 95%CI (9.72, 31.08), P=0.000 2; after 12 weeks to 3 months: MD=6.18, 95%CI (3.57, 8.79), P<0.000 01]. Conclusions The results of this study showed that respiratory training can improve exercise tolerance, ADL, and motor function in stroke patients. In consideration of the limited number of included articles as well as the heterogeneity among included articles in the current study, and the lack of long-term follow-up period, further studies could use more optimized respiratory training programs to conduct high-quality researches with bigger sample sizes.
Objective To systematically review the efficacy of six cognitive interventions on cognitive function of patients with mild cognitive impairment after stroke. Methods The PubMed, EMbase, Cochrane Library, SinoMed, WanFang Data and CNKI databases were electronically searched to collect randomized controlled trials on the effects of non-drug interventions on the cognitive function of patients with mild cognitive impairment after stroke from inception to March 2023. Two reviewers independently screened the literature, extracted data, and assessed the risk of bias of the included studies. Network meta-analysis was then performed using Openbugs 3.2.3 and Stata 16.0 software. Results A total of 72 studies involving 4 962 patients were included. The results of network meta-analysis showed that the following five cognitive interventions improved the cognitive function of stroke patients with mild cognitive impairment: cognitive control intervention (SMD=−1.28, 95%CI −1.686 to −0.90, P<0.05) had the most significant effect on the improvement of cognitive function, followed by computer cognitive training (SMD=−1.02, 95%CI −1.51 to −0.53, P<0.05), virtual reality cognitive training (SMD=−1.20, 95%CI −1.78 to −0.62, P<0.05), non-invasive neural regulation (SMD=−1.09, 95%CI −1.58 to −0.60, P<0.05), and cognitive stimulation (SMD=−0.94, 95%CI −1.82 to −0.07, P<0.05). Conclusion Five cognitive interventions are effective in improving cognitive function for stroke patients with mild cognitive impairment, among which cognitive control intervention is the most effective. Due to the limited quantity and quality of the included studies, more high-quality studies are needed to verify the above conclusion.
Objective To explore whether the effect of cloud rehabilitation system on motor dysfunction and activities of daily living (ADL) of stroke patients is not inferior to hemiplegia manual treatment. Methods This study adopted a multicenter randomized controlled trial design. A total of 118 stroke patients were enrolled from 5 hospitals in China between April 2018 and April 2019, and they were randomly divided into a trial group and a control group, with 59 patients in each group. The trial group adopted hemiplegia manual treatment (≥30 min per time, once a day) and cloud rehabilitation training (30 min per time, once a day), and the control group adopted hemiplegia manual treatment alone (≥30 min per time, twice a day). All patients received continuous treatment for 2 weeks, and followed up for 2 weeks after that. The Brunnstrom stage (BRS), IK exercise stage, and Modified Barthel Index (MBI) were used to evaluate the motor function and ADL before and 4 weeks after treatment. Results There was no significant difference in gender, age, course, hemiplegia side, source (inpatient/outpatient) or hospital grade between the two groups (P>0.05), which were comparable. Compared with those before treatment, there were significant improvements in the BRS (upper and lower extremities), IK exercise stages (upper and lower extremities), and MBI scores in both groups 4 weeks after treatment (P<0.05). The four-week improvements in motor function indicators (BRS and IK) of the trial group were not inferior to those of the control group (P<0.05), and there was no significant difference in MBI score between the two groups 4 weeks after treatment (F=1.498, P>0.05). Conclusion The cloud rehabilitation system is not inferior to hemiplegia manual treatment in improving the limb motor function or ADL of patients .
Objective To analyze the influence of COPD on the structure and function of left ventricular. Methods Sixty-nine COPD patients ( mean age: 69. 0 ±7. 8 yrs) and forty healthy controls ( mean age: 67. 8 ±7. 6 yrs) were enrolled in this study. Both groups underwent Doppler echocardiography.Heart rate ( HR) were recorded. Left ventricular end-diastolic volume ( LVEDV) , left ventricular enddiastolic diameter ( LVEDD) , interventricular septum( IVS) , stroke volume ( SV) , and cardiac output ( CO)were measured. The changes of left ventricular were compared between the COPD patients and the healthy controls, and also between the COPD patients with or without chronic cor pulmonale. Results Compared with the healthy controls, movement range of IVS, LVEDD, LVEDV, and SV reduced significantly ( P lt;0. 05) , and HR raised significantly in the COPD patients ( P lt; 0. 05) . CO had no significant difference between two groups ( P gt;0. 05) . Sub-group analysis indicated that the thickness and movement range of IVSwere greater in the patients with cor pulmonale secondary to COPD than those without cor pulmonale ( P lt;0. 05) . Conclusions In COPD patients, left ventricular chamber size decreases, and left ventricular systolic function is impaired. Left ventricular function is impaired more severe in cor pulmonale secondary to COPD than COPD without cor pulmonale.
