Background: Scapular dyskinesia can be caused by several factors, such as poor posture (thoracic kyphosis or cervical hyperlordosis) or changes in the activation and coordination of the scapular stabilizing muscles. Therefore, the term is correctly used when there is a change in the scapular biomechanics at rest or during movement. Objective: The objective of this study was to evaluate the effects of PNF on scapular dyskinesia of volleyball players. Methods: This is a quasi-experimental study with volleyball players. The study sample consisted of 32 individuals of both sexes, with ages between 14 and 17 years who presented scapular dyskinesia, identified by anamnesis and physical examination. To collect data, a sociodemographic evaluation developed by the researchers was used, containing personal data, pain evaluation through the Nordic Pain Questionnaire, and an image and video record was made for the analysis of photogrammetry and the Scapular Dyskinesia Test. For the data analysis a significance level of 5% was adopted. Results: Most of the sample (71.9%) practiced volleyball for more than a year, 65.6% trained three times a week, 84.4% were attackers, 96.9% were right-handed and 100% of the sample presented pain symptoms in the last twelve months. There was a significant difference in the abduction test of both scapulae and in the weight discharge of the right upper limb after the protocol. Conclusion: PNF has been shown to be effective in the initial phase of the treatment of scapular dyskinesia acting on neuromuscular balance and scapular orientation.

ABSTRACT Objetive To determine the percentage of correctness of the Orbital Index (OI) for estimation of sex, ancestry and age in Brazilian skulls. Methods Cross-sectional study of 183 human dry skulls from the southeastern Brazil. A total of 100 skeletons were males and 83 females; of which 36 were aged up to 39 years, 60 aged between 40 and 59 years, and 87 aged 60 years or older. As for ancestry, 103 were from white, 51 mixed race, and 29 black individuals. The OI was calculate by the formula = height/width x 100. The data were submitted to Student’s t test, F (ANOVA), Tukey and Kruskal Wallis tests as well as to discriminant analysis, with a 5% significance level. Results The sample was characterized as mesoseme, with a mean age of 56.62 (±19.97) years. No significant difference was observed (p=0.511) between the OI in females (right: 86.43 ± 6.58 and left: 86.70 ± 5.93) and males (right: 85.78 ± 6.69 and left: 86.37 ± 6.20). There were no significant differences between age, ancestry and the variables analyzed (p>0.05). The right and left orbital widths were significantly dimorphic between sexes (p<0.001). The percentage of correctness of the method for estimation of sex, age and ancestry was found to be 65.6%, 43.7%, and 43.6%, respectively. Conclusions The OI is not an appropriate method for estimation of sex, ancestry and estimation of age in this Brazilian sample. The methodology should be expanded to other population groups so that it can be improved.

Abstract Introduction. Monitoring muscle stiffness in athletes can be a good method of assessing fatigue caused by high training loads, and the early detection of fatigue can help prevent the occurrence of micro-trauma in the muscles that can cause contusions. The research carried out by Wilson et al. [1] confirmed that an optimal level of muscle stiffness is significantly correlated with high muscle loads. The aim of the current study was to determine changes in muscle stiffness of the left and right thighs during six weeks of plyometric training (PT) in volleyball players. Material and methods. The study involved 16 volleyball players from the second-league Opole University of Technology Club (age = 21.12 ± 1.66 years, height = 191.62 ± 5.73 cm, and weight = 86.25 ± 6.66 kg) with at least five years of competitive experience (7.5 ± 2.44 years). Muscle stiffness was measured during three stages of the plyometric training using a MYOTON PRO device (Estonia). Results. An RM-ANOVA analysis showed a significant difference in the resting stiffness of the semitendinosus (posterior thigh) muscles of the left and right limbs before the plyometric training began, but no significant differences were found in the stiffness of these muscles in the fourth or sixth weeks of training. The results of the measurement performed for the anterior muscles of the thigh did not reveal a significant difference in the stiffness of the left limb compared to that of the right limb in subsequent weeks of training. Conclusion. The loads used in plyometric training in volleyball players caused a decrease in the differences in muscle stiffness between the left and right limbs, and in both limbs, adaptation trended towards an increase or a decrease in stiffness.

AIMS: To evaluate the posture of subjects with lower limb amputee.METHODS: Ten subjects participated in the study, males, with 38,2 ± 8,2 years, with unilateral lower limb amputation and prosthesis users. For the postural evaluation, the Postural Evaluation Software (SAPO) was used, and the images were evaluated according to the software protocol. Data were analyzed through descriptive and inferential statistics (independent t test), with a significance level of p ≤ 0,05.RESULTS: The main alterations observed were: rearfoot valgus enlargement, flexed ankle, head tilted to the right and trunk in flexion. When compared the posture according to time of amputation, was observed a statistically significant difference in the horizontal asymmetry of scapula in relation to T3 (p = 0,004), being that subjects with amputation time of up to six years presented the left scapula higher than the right one (-5,28 ± 8,16°) and those with more than six years of amputation had the right upper right scapula (19,42 ± 11°). In the comparison between amputation levels, there was a statistically significant difference in the ankle angle (p = 0,008), with subjects with amputation below the knee presenting greater ankle flexion (81,97 ± 1,72°) than those with amputation at the level of the knee and above this (87,30 ± 2,65°).CONCLUSIONS: The findings of the present study demonstrate that all the evaluated subjects presented some postural alteration, however, it cannot be affirmed that the postural asymmetry of these is due to the amputation.

Background: After the Japanese nuclear power plant disaster in 2011, many residents became concerned about health effects of radiation. We aimed to evaluate the effectiveness of a training program for public health and school health nurses to improve their skills and expertise for better support to residents and students. Methods: This was a quasi-experimental study using single-group and pre-post comparison in 2016 in Hiroshima, Kagoshima and Hyogo prefectures of Japan. The educational evaluation was conducted through each sub-item of Bloom’s attainment goals. The evaluation of effectiveness was surveyed among 61 participants before and immediately after the workshop, and at 1-week and 1-month later. The analysis compared initial scores obtained before the workshop with subsequent responses. Where a significant difference was observed among three-group or more in the Friedman test, the Wilcoxon signed-rank test was used for two-group comparisons across the time periods. The significance level was set at P<0.05. Results: Data of 54 participants were analyzed. The knowledge based on Bloom’s taxonomy was increased as the number of correct responses increased significantly after the workshop (P<0.001). Cognitive domain was significantly increased after 1-week and 1-month (P<0.001). Affective and psychomotor performances were also increased compared with prior. Participants increased vocabulary related to radiation and developed confidence in radiation disaster recovery measures. Conclusion: Each sub-item of the Bloom’s attainment (goal, cognitive, affective, psychomotor) has almost been reached and the effect was maintained even after 1-month. By learning concrete words, they could explain accurately. Participants improved their confidence after receiving the training to respond and clarify the radiation anxieties to the community people.

OBJECTIVE: This study assessed the anterior-posterior positioning of the upper and lower first molars, and the degree of rotation of the upper first molars in individuals with Class II, division 1, malocclusion. METHODS: Asymmetry I, an accurate device, was used to assess sixty sets of dental casts from 27 females and 33 males, aged between 12 and 21 years old, with bilateral Class II, division 1. The sagittal position of the molars was determined by positioning the casts onto the device, considering the midpalatal suture as a symmetry reference, and then measuring the distance between the mesial marginal ridge of the most distal molar and the mesial marginal ridge of its counterpart. With regard to the degree of rotation of the upper molar, the distance between landmarks on the mesial marginal ridge was measured. Chi-square test with a 5% significance level was used to verify the variation in molars position. Student's t test at 5% significance was used for statistical analysis. RESULTS: A great number of lower molars mesially positioned was registered, and the comparison between the right and left sides also demonstrated a higher number of mesially positioned molars on the right side of both arches. The average rotation of the molars was found to be 0.76 mm and 0.93 mm for the right and left sides, respectively. CONCLUSION: No statistically significant difference was detected between the mean values of molars mesialization regardless of the side and arch. Molars rotation, measured in millimeters, represented ¼ of Class II.

Background: Monitoring the adherence of pregnant women to taking iron supplements indicates controlling the appropriateness of taking a certain number of supplements. This increases the odds of effective iron absorption; a process that occurs by consuming at least 30 iron pills a month to prevent gestational anemia. This study aimed to determine the effects of monitoring pregnant women’s compliance in taking up iron supplements through an Android application in Jambi City, Indonesia. Methods: This was a quasi-experimental single group study with a pre-test-post-test design. The study subjects included 50 pregnant women in their third trimester referring to 3 maternity Hospitals in Jambi City, Indonesia, in 2020. Initial data were obtained through Hemoglobin (Hb) measurements before being given a monitoring application and subsequent Hb level checks after giving the application. The obtained data were analyzed by t-test and Mann-Whitney U test in SPSS v. 16. A significance level of 5% was considered. Results: The results obtained in the initial examination indicated that the minimum Hb level was equal to 7.3 g/dL and the maximum level was measured as 11.2 g/dL. After the intervention, the Hb level increased to a minimum of 7.6 g/dL and a maximum of 12.2 g/dL. The Mann-Whitney U test data suggested a significant difference in the degree of compliance of pregnant women with iron supplementation (P=0.010). Conclusion: Monitoring through the Android application increased pregnant women’s compliance with taking iron supplements and presented a linear impact on increasing their Hb level.
