  • Analysis of long-term effect on cardiopulmonary resuscitation skills in medical students with different training methods

    ObjectiveTo analyze the long-term effect on cardiopulmonary resuscitation skill between video-led and scene simulation training and traditional instructor-led courses in medical student with eight-year program.MethodsNinety-nine medical students with eight-year program who studied in Peking Union Medical College were trained in cardiopulmonary resuscitation skill from January to February 2018. They were randomly divided into two groups, 53 students participated in basic life support course training, which belonged to video-led and scene simulation training as the trial group, and 46 students were trained by traditional instructor-led courses as the control group. In January 2019, the above 99 students were re-evaluated for cardiopulmonary resuscitation, and the outcome of cardiopulmonary resuscitation skill test in total scores and sub-items scores between two groups were compared. The data were analyzed using t test and Wilcoxon rank sum test.ResultsThe total average scores of the trial group (8.02±1.11) was higher than that of the control group (6.85±1.50) (P<0.05). The sub-items scores of the trial group in the three aspects of on-site assessment, chest compressions and simple respirators (1.64±0.37, 3.38±0.46, 1.52±0.58) were higher than those of the control group (1.33±0.45, 2.80±0.76, 1.19±0.58) (P<0.05). In terms of opening airway, there was no significant difference in scores between the two groups (1.02±0.47 vs. 1.10±0.45, P>0.05). The excellent rate of the trial group (60.3%) was significantly higher than that of the control group (30.4%) (P<0.05), and the unqualified rate (5.6%) was significantly lower than that of the control group (21.7%) (P<0.05).ConclusionsThe video-led and scene simulation training has a better effect on cardiopulmonary resuscitation skills acquisition and long-term maintenance than traditional instructor-led courses for medical student with eight-year program.

  • Indoor simulation training system for brain-controlled wheelchair based on steady-state visual evoked potentials

    Brain-controlled wheelchair (BCW) is one of the important applications of brain-computer interface (BCI) technology. The present research shows that simulation control training is of great significance for the application of BCW. In order to improve the BCW control ability of users and promote the application of BCW under the condition of safety, this paper builds an indoor simulation training system based on the steady-state visual evoked potentials for BCW. The system includes visual stimulus paradigm design and implementation, electroencephalogram acquisition and processing, indoor simulation environment modeling, path planning, and simulation wheelchair control, etc. To test the performance of the system, a training experiment involving three kinds of indoor path-control tasks is designed and 10 subjects were recruited for the 5-day training experiment. By comparing the results before and after the training experiment, it was found that the average number of commands in Task 1, Task 2, and Task 3 decreased by 29.5%, 21.4%, and 25.4%, respectively (P < 0.001). And the average number of commands used by the subjects to complete all tasks decreased by 25.4% (P < 0.001). The experimental results show that the training of subjects through the indoor simulation training system built in this paper can improve their proficiency and efficiency of BCW control to a certain extent, which verifies the practicability of the system and provides an effective assistant method to promote the indoor application of BCW.

  • Effect of virtual scene simulation training combined with midium frequency impulse electrotherapy on upper limb function of hemiplegic patients

    ObjectiveTo investigate the effect of virtual scene simulation training combined with midium frequency impulse electrotherapy on upper limb function and daily living ability of hemiplegia patients.MethodsFrom March to October 2019, 50 hemiplegic patients were recruited and randomly assigned to the trial group and the control group, with 25 patients in each group. The control group was given routine rehabilitation training, while the trial group was given virtual scene simulation training and medium frequency impulse electrotherapy on the basis of routine rehabilitation training. The Fugl-Meyer Assessment-Upper Extremities (FMA-UE), Simple Test for Evaluating Hand Function (STEF), and Modified Barthel Index (MBI) were used to assess patients’ upper limb function and daily living ability before treatment and after 8 weeks of treatment.ResultsBefore treatment, the FMA-UE, STEF, and MBI scores of the trial group vs. the control group were 22.88±5.18 vs. 23.44±6.26, 40.12±4.82 vs. 41.44±4.54, and 51.40±7.29 vs. 48.60±7.00, respectively, and none of the between-group differences was statistically significant (P>0.05); after 8 weeks of treatment, the FMA-UE, STEF, and MBI scores of the two groups were 39.48±6.35 vs. 33.52±6.53, 59.08±7.54 vs. 52.52±5.83, and 71.00±8.78 vs. 62.40±9.37, respectively, and all of the between-group differences were statistically significant (P<0.05). After 8 weeks of treatment, the FMA-UE, STEF and MBI scores of the two groups of patients were significantly improved compared with those before treatment (P<0.05), and the improvement of each score of the trial group was significantlybetter than that of the control group (P<0.05). No stroke recurrence, electric burn, or other adverse reactions occurred in the two groups after treatment. ConclusionVirtual scene simulation training combined with midium frequency impulse electrotherapy can effectively improve the upper limb function of patients with hemiplegia and improve their quality of life.
