We analyzed lesser diameter and distribution of fiber types in different skeletal muscles from female Wistar rats using a histoenzymology Myofibrillar Adenosine Tri-phosphatase (mATPase) method. Fragments from muscles were frozen and processed by mATPase in different pH. Adult and weanling rat soleus muscles presented a predominance of type I fibers and larger fiber diameters. In the plantar muscle in adult rats, the type IIB fibers demonstrated greater lesser diameter while in the weanling animals, types I and IIB fibers were larger. The plantar muscle of animals of both ages was composed predominantly of the type IID fibers. The type IID fibers were observed in similar amounts in the lateral gastrocnemius and the medial gastrocnemius muscles. Type IIB fibers showed predominance and presented higher size in comparison with other types in the EDL muscle. The present study shows that data on fiber type distribution and fiber lesser diameter obtained in adult animals cannot always be applied to weanling animals of the same species. Using the mATPase, despite the difficult handling, is an important tool to determine the different characteristics of the specific fibers in the skeletal muscle tissue.

The objective of this study was to verify self-care guidelines together with lower limb home exercises alter ankle and foot plantar pressure and alignment in patient with Type 2 Diabetes Mellitus (DM) measuring health and sociodemographic factors. The health factors analyzed were sensitivity and circulation aspects, risk rating, and neuropathy symptom score, ankle and foot alignment (photogrammetry), plantar pressures, and postural stability (baropodometry) before and after administering these guidelines and home exercises in 97 patients type 2 DM during 10 months. The self-care guidelines and exercises changed the forefoot alignment (Right Foot – Initial vs Final, p = 0.04; Left Foot, P<0.01), the center of the force displacement in the mediolateral (Right Foot - Initial versus Final, p = 0.02; Left Foot, P<0.01), and the anterior-posterior (Right foot - Initial versus Final, p = 0.01) direction, and body balance (Initial versus Final, p = 0.02). There was no change in the remaining assessed parameters. Self-care associated with the guidelines for home exercises for the lower limbs in patients with type 2 DM are effective in maintaining and improving the alignment of the feet, mediolateral stability and prevention of complications.

Objective: Evaluation of the effects of exergames in women with fibromyalgia on the impact of the disease—pain threshold and physical variables—compared to performing stretching exercises. Materials and Methods: Thirty-five women were enrolled in the study and divided by simple randomization into two treatment groups: the control group (n = 19) and the Wii™ (exergames) group (n = 16). Participants were evaluated using the fibromyalgia impact questionnaire (FIQ), algometry, step tests, cardiopulmonary parameters, and fatigue in the lower limbs. The participants underwent treatments for a period of 7 weeks with three 1-hour sessions weekly and were reevaluated after the 10th and the 20th sessions. Results: The exergames group showed significant reduction of their fibromyalgia symptoms, as demonstrated by lower FIQ scores in the key domains on questions regarding missed work, pain, fatigue, problems resting, stiffness, anxiety, and depression. Significant improvements were observed in mean algometric values in the cervical region, the second chondrocostal junction, the lateral epicondyle, left medial knee border, left occipital region, trapezius, supraspinatus, gluteal muscles, and the greater trochanter. Improved cardiovascular adaptation was reflected by decreased systolic blood pressure, reduction in fatigue of the lower limbs assessed by the CR10 Borg scale, and improved exercise capacity assessed by a step test. Conclusion: Exergames have the potential to increase exercise capacity, decrease the impact of fibromyalgia, promote cardiovascular adaptation, reduce fatigue of lower limbs, and improve the pain threshold in women with fibromyalgia.

The purpose of this study was to evaluate the intraexaminer and interexaminer reliability of image assessment of infrared thermography of the plantar surface of people with diabetes mellitus. Fifty-one participants with diabetes were included. The interexaminer reliability (test) consisted of measuring the temperature of the plantar surface by 2 evaluators who separately performed the analysis of thermographic images. The intraexaminer reliability (retest) consisted of the revaluation of the images by a single evaluator 10 days after the first analysis. The analysis of intrareliability and interreliability indicated excellent levels of correlation (intraclass correlation coefficient >0.75, 95% confidence interval >0.70) in the plantar surface points analyzed. Infrared thermography image evaluation identified intrareliability and interreliability for temperature analysis of the plantar surface of people with diabetes mellitus. However, further studies need to be conducted to assess validity and its application in health care.

RESUMOObjetivo:investigar a ansiedade e a espiritualidade de estudantes universitários e a relação entre elas.Método:para a coleta de dados, foi utilizado o Inventário de ansiedade traço-estado (IDATE) e a Escala de Espiritualidade de Pinto e Pais-Ribeiro.Resultados:participaram 609 alunos, sendo que 91,5% apresentam níveis moderados e altos de ansiedade-traço; 92,9%, os mesmos níveis de ansiedade-estado e 93,8% alto escore de espiritualidade. O teste de regressão linear múltipla apontou relação signifi cativa entre a ansiedade e a presença de desconfortos físicos, de movimentos pouco comuns e necessidade de tratamento. Os maiores níveis de ansiedade estiveram associados ao sexo feminino, à ausência de atividades de lazer e aos baixos níveis de otimismo da escala de espiritualidade.Conclusão:é importante o desenvolvimento de estratégias de enfrentamento da ansiedade que, por sua vez, podem estar voltadas a fatores protetores, como a espiritualidade.

To evaluate the effectiveness of abdominopelvic training by virtual reality compared to pelvic floor muscle training (PFMT) using a gym ball (a previously tested and efficient protocol) on postmenopausal women's pelvic floor muscle (PFM) strength. A randomized controlled trial was conducted with 60 postmenopausal women, randomly allocated into two groups: Abdominopelvic training by virtual reality - APT_VR (n=30) and PFMT using a gym ball - PFMT_GB (n=30). Both types of training were supervised by the same physical therapist, during 10 sessions each, for 30 minutes. The participants' PFM strength was evaluated by digital palpation and vaginal dynamometry, considering three different parameters: maximum strength, average strength and endurance. An intention-to-treat approach was used to analyze the participants according to original groups. No significant between-group differences were observed in most analyzed parameters. The outcome endurance was higher in the APT_VR group (p=0.003; effect size=0.89; mean difference=1.37; 95% CI=0.46 to 2.28). Both protocols have improved the overall PFM strength, suggesting that both are equally beneficial and can be used in clinical practice. Muscle endurance was higher in patients who trained using virtual reality.
