Objective To systematically evaluate the orthotic effect of functional electrical stimulation (FES) on the improvement of walking in stroke patients with foot drop. Methods The randomized controlled trials (RCTs) that investigated the orthotic effect of FES on walking in stroke patients with foot drop were electronically searched in the databases such as PubMed, Web of Science, The Cochrane Library (Issue 1, 2013), EMbase, CBM, CNKI, VIP and WanFang Data from January 2000 to January 2013, and the relevant references of included papers were also manually searched. Two reviewers independently screened the trials according to the inclusion and exclusion criteria, extracted the data, and assessed the methodology quality. The meta-analyses were performed using RevMan 5.1 software. Results A total of 8 RCTs involving 255 patients were included. The results of meta-analyses on 4 RCTs showed that, compared with the conventional rehabilitation intervention, the functional electrical stimulation could significantly improve the walking speed, with significant difference (MD=0.09, 95%CI 0.00 to 0.18, P=0.04). The other indicators were only descriptively analyzed due to the incomplete data. Conclusions Functional electrical stimulation is effective in improving walking speed, but it is uncertain of other therapeutic indicators. So it should be further proved by conducting more high quality, large sample and multi-center RCTs.
【Abstract】 Objective To evaluate the effectiveness of percutaneous fixation of pelvic fracture by Acutrak full thread headless hollow compression screw. Methods Between March 2008 and April 2010, 31 patients with pelvic fracture underwent percutaneous fixation surgery with Acutrak full thread headless hollow compression screw (surgical group). The effectivenss was compared with those of 14 patients with pelvic fracture treated conservatively (control group). There was no significant difference in age and sex between 2 groups (P gt; 0.05). The injury was more severe in surgical group than in control group. The standard of short-term recovery was active turning over and walking for 5 steps with walking aids. The standard of long-term recovery was pain, gait, fracture healing, and function recovery. Results In surgical group, the other patients reached the standard of short-term recovery at 1-4 days after injury except 1 patient who had sacral plexus injury; in control group, the patients could turn over at 9-13 days (Tile type A2) and 17-25 days (Tile type B2) respectively, and could walk at 17-21 days (Tile type A2) and at 45-57 days (Tile type B2) respectively. The patients of 2 groups were followed up 6-19 months. The time of fracture healing was 2-6 months. The long-term results were excellent in 29 cases and good in 2 cases in surgical group, and were excellent in 8 cases and good in 6 cases in control group, showing significant difference between 2 groups (χ2=6.636, P=0.017).Conclusion Percutaneous internal fixation combined with Acutrak full thread headless hollow compression screw can provide more effective treatment. It can alleviate patients, pain quickly, improve life quality, and has better long-term effectiveness.
Objective To compare the environmental microbiological and physical monitoring parameters between the temporary extended medical area and the normal area during the flexible allocation of ward, summarize the rule and find the potential risk points of infection control. Methods From April 10th to 23rd, 2023, prospective environmental microbial monitoring and physical parameter monitoring were carried out in a ward of Zhongnan Hospital of Wuhan University, and the monitoring results under different scenarios were compared and analyzed. Results In general, the carbon dioxide (CO2) concentration, particulate matter 2.5 (PM2.5) concentration, temperature, and relative humidity in the temporary medical area were better than those in the inpatient rooms (P<0.05), but there was no statistically significant difference in the amount of microorganisms detected on the surface of environmental objects or the hands of medical staff (P>0.05). After the start of the temporary medical area, the amount of microorganisms detected on the surface of environmental objects, CO2 concentration, and temperature in the inpatient rooms were higher than those in the temporary medical area (P<0.05), the PM2.5 concentration in the inpatient rooms was lower than that in the temporary medical area (P<0.05), and there was no statistically significant difference in the amount of microorganisms detected on the hands of medical staff or relative humidity between the two areas (P>0.05). Compared with those in the same area when the temporary medical area was not started, in the inpatient rooms after the start, the amount of microorganisms detected in the air, CO2 concentration, temperature, and relative humidity were lower (P<0.05), the amount of microorganisms detected on the surface of environmental objects and PM2.5 concentration were higher (P<0.05), and there was no statistically significant difference in the amount of microorganisms detected on the hands of medical staff between the two periods (P>0.05); in the temporary medical area after the start, the PM2.5 concentration was higher (P<0.05), the CO2 concentration and temperature were lower (P<0.05), and the differences in the relative humidity and amounts of microorganisms detected on the surface of environmental objects and the hands of medical staff between the two periods were not statistically significant (P>0.05). Regardless of whether the temporary medical area was activated or not, Filamentous fungi had the highest detection rates in air samples, and Staphylococcus epidermidis had the highest detection rates in both environmental surface samples and medical staff hand samples. Conclusion A series of environmental risks such as environmental microbial load and poor ventilation caused by temporary medical areas should be paid attention to.
