Methods: Thirty-two 2-month-old male Wistar rats were divided as follows: the EG Group (comprised of 10 rats whose mothers underwent gestational stress), the EO Group (11 rats subjected to postnatal stress), and the SE Group (control group, comprised of 11 animals that went through no stress whatsoever). Upon reaching adulthood, these male rates were introduced to females and had their sexual behavior assessed based on the number of mounts. Results: The animals from the EP Group showed significantly fewer mounts (74 ± 24.77, p < 0.05) when compared to those from the EG (108.9 ± 35.27) and SE (99.6 ± 20.76) Groups. Conclusion: The rats that underwent stress during the first days of life mated fewer times than those whose mothers were subjected to stress during pregnancy. The latter had their sexual behavior unaltered.展开更多

Nevertheless, most victims do survive and need treatment, and hand function is one that has to be dealt with in the rehabilitation process. Kinesio®?Taping (KT) is a bandaging method that can be applied along the muscle fibers to provide stimulation. Studies have shown its efficacy in providing afferent stimuli to weakened muscles, thus eliciting contraction with greater recruiting of motor units and inducing neuroplasticity. Benefits to the paresthesia hand have not been reported. Objective: Investigate the effects of KT on hand function in hemiparetic patients. Material and Methods: An evaluator-blinded, randomized clinical trial involving stroke victims was carried out in a physical therapy outpatient clinic. One group underwent KT intervention and the other was a control group. The Modified Ashworth Scale (MAS) and the Box and Block Test (BBT) were used as assessment tools. A data entry form was used in the Epi-info 7 software and descriptive statistics was thus calculated. The software BioStat 5.0 was employed when doing statistical tests. Associations were regarded as statistically significant when p 0.05. Results: Eight individuals were randomly assigned to two groups. All those who had received treatment with KT had spasticity improved by one point, but there was no significant improvement in BBT. Conclusion: KT was effective when it came to improving spasticity and it may be an option in rehab, but it had no effect on gross manual dexterity. Nevertheless, it can be of help as part of a functional training program.展开更多
