ABSTRACT
Objective:To observe the effect of enriched rehabilitation on dual-task gait disorder after a transient ischemic attack (TIA) and explore its mechanism.Methods:Sixty TIA patients were randomly divided into a control group and an observation group, each of 30. Another 30 healthy counterparts were selected to form a healthy control group. All of the TIA patients were given routine medication to lower blood pressure and improve brain function, while the observation group was additionally provided with enriched rehabilitation training for 12 weeks. Before and after the intervention, the gait and cognitive functioning of all of the subjects were quantified and their event-related potentials (P300s) and serum brain-derived neurotrophic factor (BDNF) levels were also measured.Results:Before the treatment there were significant differences between the TIA groups and healthy controls in all of the measurements, but there were no significant differences between the control and observation groups. After the treatment, no significant improvement was observed in any of the control group′s results, but there was significant improvement in the observation group′s gait parameters, cognitive functioning, average serum BDNF concentration and in the average latency and amplitude of its P300 signals.Conclusions:Enriched rehabilitation can improve the gait of TIA patients, perhaps through increasing their serum BDNF concentration and improving their cognition.
ABSTRACT
Objective:To explore the effect of high-frequency repeated magnetic stimulation on the body-specific attention of healthy adults.Methods:Forty healthy adults were recruited and randomly divided into a repeated stimulation group and a sham stimulation group, each of 20. A " Pathleader" medical device which can produce magnetism was used to stimulate the initial segment of the deep branch of the radial nerve on each subject′s non-dominant side in the repeated stimulation group. The intensity was set within the subject′s tolerable range but sufficient to induce obvious dorsiflexion of the wrist joint. The frequency was 50Hz, the stimulation time was 2s with 1s intervals. The entire stimulation sequence lasted 36min. In the sham stimulation group, the device and parameters were the same but the coil was rotated 90° so there was no actual stimulation. The difference between the reaction time in the body condition and the reaction time in the control condition was defined as body-specific attention. Body-specific attention was quantified before stimulation, right after stimulation and 10 minutes later.Results:Right after stimulation body-specific attention was no different from before stimulation in either group. Ten minutes after real stimulation, body-specific attention had increased significantly, but there was no significant difference in the sham stimulation group.Conclusion:High-frequency repeated magnetic stimulation of a peripheral nerve can improve the body-specific attention of neurologically-intact healthy adults. The effect may arise from initial inhibition followed by enhancement.
ABSTRACT
Objective To evaluate the effects of breastfeeding behavior through the implementation of family-centered empowerment education in primiparas.Methods According to random digit table,128primiparas in our hospitals were divided into the experimental group and the control group with 64 cases in each group from August 2014 to April 2015.At last 58 patients in the observation group and 59 patients in the control group completed the research.Those primiparas in the experimental group were given the familycentered empowerment education.The control group received conventional methods.Results The scores of breastfeeding self-efficacy,perceived social support and breastfeeding behavior of primiparas in the experimental group were 129.64±12.94,58.94±8.97,89.84±11.32,higher than the control group,101.78±78.67,50.27±10.56,71.56±12.03,the differences had statistical significance between two groups,t=9.656-10.487,P ＜ 0.05.Conclusions Using the family-centered empowerment education can effectively improve the breastfeeding self-efficacy,perceived social support and breastfeeding behavior in primiparas.
