Background: The foot is the foundation of the body. The stability of the osseous hindfoot structure is crucial in bipedal locomotion. The subtalar joint is responsible for conversion of the rotatory forces of the lower extremities and dictates the movements of the midtarsal joints and the forefoot. In a hyperpronated foot, excessive abnormal pronation results in partial to full obliteration of the sinus tarsi. The hypothesis is that the HyProCure device will prevent obliteration of the sinus tarsi, thereby stabilizing the subtalar joint complex and eliminating the excessive forces to the proximal and distal musculoskeletal system that occur with every step. Methods: Five fresh-frozen human foot cadaver specimens that represented pathologic hindfoot and midfoot instability and partial to full obliteration of the sinus tarsi were axially compressed to 2,000 N and internally rotated by 15° to produce maximum pronation of the subtalar joint using a biaxial materials testing machine. The forces were measured across the posterior and anterior talocalcaneal joint facets before and after placement of the HyProCure stent. Results: The subtalar joint stabilized after placement of the HyProCure sinus tarsi stent. The mean ± 1 SD forces in the posterior talocalcaneal joint increased from 795.88 ± 106 N to 1,004.86 ± 72.41 N (P < 0.05, two-tailed paired t test). The mean ± SD forces at the anterior talocalcaneal joint decreased from 520.15 ± 127.18 N to 394.56 ± 73.83 N (P < 0.05), shifting the contact area posteriorly. Conclusions: Placement of the HyProCure subtalar stabilization stent in a hyperpronated foot prevents excessive talar subluxation and assists in proper distribution of the axial loads on the subtalar facet joints.

Objective (1)Through the blood physiological and biochemical tests during the altitude training, to analyze the body function of swimmers in this stage.(2) Through the individual lactate threshold tests before and after the altitude training,to analyze the effects of altitude training. Methods Eight swimmers took a 26-day altitude training session.The individual lactate threshold test was carried out by the Swedish Monak839E power cycle progressive loading method before and after the training;During the altitude training period, 5ml of the subjects' elbow vein was extracted and tested on an empty stomach and in a quiet state every Monday morning. Results (1)When swimmers reached the plateau, the hemoglobin value was indistinguishable from the plain(male 156.2±7.01,female 135.7±8.75g/L),From the hemoglobin value (male 154.03 + 5.67, female 134.23 + 9.66g/L), there was a decrease in both male and female in the second week.But hypoxia stimulated red blood cell production, and the body itself was gradually adapting to the training load.Thus, the hemoglobin value of the third week (male 157.17 + 3.7, female 141.93 + 10.06g/L) was significantly improved, and higher than the level of the first week.During the altitude training period, the mean value of male’s blood testosterone was 474.33 + 97.06ng/dl, and the female’s blood testosterone was 33.67 + 17.25ng/dl.Male’s blood testosterone was lower than the mean of the national team, because the study participants were youngers who were not fully developed and had shorter training years.There were different trends in blood testosterone value between male and female. Male’s blood testosterone values during the Monday morning of these three weeks were 479.67±76.25、492.33±83.61、451±153.41ng/dl respectively.female’s blood testosterone values during the Monday morning of these three weeks were 29.33±21.83、32±23.26、39.67±9.29ng/dl respectively.These further indicated that this altitude training plan was more suitable for male with shorter training years, and the body had certain fatigue accumulation, but the decrease range was within a reasonable range.However, the increase of blood testosterone per week in female indicated that the training stimulation depth was not enough, and the potential of athletes should be further explored.According to the changes of creatine kinase, the sensitivity of male to the change of altitude training intensity was also shown, and the highest value of creatine kinase was 731U/L in the first week.(2) From the value of the individual lactate threshold before and after altitude training, no matter male or female,the change was not obvious, but was generally improved, this may be the altitude training adopted the pattern of three and a half weeks, training time was short.Secondly, as a professional athlete, the "plastic space" gradually decreased with the extension of the training years.Most of the peak blood lactate occurred in 1-3 minutes of recovery period.and the average value increased from 8.96 + 1.86mmol/L before altitude training to 9.99 + 1.47mmol/L.Among them, the peak value of male’s blood lactate was increased from 8 + 2.22mmol/L before the altitude training to 10.91 + 1.43mmol/L, and there was a significant difference in the peak of blood lactate before and after the altitude training.However, the peak value of female’s blood lactate was decreased from 9.92 + 0.79mmol/L before the altitude training to 9.07 + 0.88mmol/L. This was mainly due to the fact that a member of the swimmers had caused the result, and this swimmer’s enduring lactate level was lower than the one before the plateau. Conclusions The altitude training generally improved athletes’ training ability, but based on factors such as training age, gender, should be targeted according to the individual situation of each athlete training plan, so as to achieve more from less.

Introduction Plaster of Paris (PoP) impregnated bandages have been used to maintain the position of bones and joints for over a century. Classically, wool dressing is applied to the limb before the PoP, which can then be moulded to the desired shape. A modification of this practice is to wrap the PoP bandages circumferentially in cotton before wetting and applying to the patient in an attempt to reduce inhalation of plaster dust and reduce mess. However, this may affect the water content of the cast and therefore also its setting properties and strength. This study compared the setting properties of PoP casts when used with and without cotton wrapping. Methods Sixty specimens, compliant with the American Society for Testing and Materials standards for three-point bending tests, were prepared, with thirty wrapped in cotton. All were weighed before and after water immersion, and wrapped around a plastic cylinder to mimic limb application. Bending stiffness and yield strength was measured on a servohydraulic materials testing machine at 2, 6, 12, 24, 48 and 72 hours. Results The water content of cotton-wrapped plaster was significantly higher (50%) than that of standard plaster. It had significantly lower strength up to 24 hours and significantly lower stiffness up to 72 hours. Conclusions The initial decrease in strength and stiffness of the cast wrapped in cotton may comprise the ability of the backslab to hold the joint or bone in an optimal position. Any modification of the standard plaster slab application technique should allow for the potential adverse effects on the plaster setting properties.

We defined the relative contributions of six ligaments in stabilizing the arch of the foot: plantar aponeurosis, long-short plantar ligaments, plantar calcaneonavicular ligament (spring ligament), medial talocalcaneal ligament, talocalcaneal interosseous ligament, and tibionavicular portion of the deltoid ligament. Nineteen fresh-frozen human foot specimens were used. A load of 445 N was applied axially to simulate standing-at-ease posture. Three-dimensional positions of tarsal bones before and after ligament sectioning were determined with the use of a magnetic tracking device. The motions were presented in the form of screw axis displacements, quantitating rotation, and axis of rotation orientation. After sectioning one structure, the arch did not collapse on any specimen and there was no obvious change by visual inspection. There were, however, measurable changes in tarsal bone position. Metatarsal-to-talus total rotation difference was greatest with spring ligament and deltoid ligament sectioning, with an average of 2.1° ± 1.7° and 2.0° ± 0.2° difference, respectively. Calcaneus-to-talus rotation difference was greatest with talocalcaneal interosseous ligament sectioning, with an average of 1.7° ± 1.5°. The spring ligament, deltoid ligament, and talocalcaneal interosseous ligament were most important for arch stability.

Objective: This study aimed to compare women’s body image, sexual function and satisfaction before and after gynecologic cosmetic surgery. The study also aimed to assess women husband’s sexual satisfaction. Materials and methods: This was a pretest-posttest study. A sample of 50 women attending the pelvic floor clinic of Tehran University of Medical Sciences for gynecologic cosmetic surgery was entered into the study. Surgeries included labiaplasty, clitoral hoodectomy, vaginoplasty, vaginal rejuvenation, anterior and posterior colporrhaphy, perineoplasty, and perineorrhaphy. Women were assessed for the Body Image Quality of Life Inventory (BIQLI), the Larson Sexual Satisfaction Questionnaire (LSSQ-F), and Female Sexual Function Inventory (FSFI-6) at two points in time: baseline (one week before surgery) and 3 months after surgery. Similarly, the male partners were assed for sexual satisfaction using the Larson Sexual Satisfaction Questionnaire (LSSQ-M). To analyze the data paired samples t-test was applied. Results: The mean (SD) age of women was 43.36 (8.6) years and the mean (SD) duration of marriage was 22.18 (9.7) years. Ninety-four percent had history of vaginal delivery and 58.7 percent attend surgery due to husband’s sexual dissatisfaction. The results showed that women’s body image, sexual function and couples’ sexual satisfaction improved significantly after gynecologic cosmetic surgery (p ≤ 0.001). Conclusion: The findings suggest that female genital cosmetic surgery improved the body image and sexual function of women and sexual satisfaction in couples that might lead to a more pleasurable and healthier marital relationship.

Abstract The aim of our investigation was to determine and compare the pre- and post- training body hydration status in professional and amateur male ice hockey players consumed the drinks according to their thirst sensation in winter conditions. Materials and methods: 11 amateur and 23 professional ice hockey players participated in the investigation. The players were weighted before and after training using precise scales. The body mass composition of every athlete was determined by the body composition analyzer. Every player collected mid–stream urine specimens before and after the training. Urine specific gravity (USG) was measured by urine refractometer. Results: 56% of the professional ice hockey players and 82% of amateur players were hypohydrated before training according to their USG values ≥ 1.020, 5% of professional players were dehydrated their USG values ≥ 1.030. After the training with duration of 1.5 hours the mean body mass decreased for 0.9±0.5% of pre– training value in amateur players and for 1.6±0.8% in professionals (p=0.005). After the training the professional players’ hydration status worsened: 66% were hypohydrated and 26% dehydrated according to USG, the mean USG after training was significantly higher than before it (p=0.011). USG after training did not change in amateur players: their mean USG values before and after training did not differed significantly (p=0.677). Conclusions: Fluid uptake according to thirst sensation in winter conditions cannot compensate the fluid loss at rest and during training especially in professional ice hockey players. The body mass loss exceeded value critical for performance - 2 % in one third part of professionals. The differences between two groups can be explained by higher intensity of exercises during training, the better physical conditioning and greater sweating rate in professional players in comparison with amateurs, which causes close to twice greater uncompensated fluid loss in professionals than in amateurs.

Background: Anatomical knowledge of the tarsal canal and sinus is still unclear owing to the complexity of the ligamentous structures within them, particularly the relationship with the capsules of the subtalar joints. The aim of this study was to examine the anatomical relationship between the fibrous tissues of the tarsal canal and sinus and the articular capsules of the subtalar joint. Methods: We conducted a descriptive anatomical study of 21 embalmed cadaveric ankles. For a macroscopic overview of the subtalar joint, we removed the talus in 18 ankles and separated the fibrous tissues from the surrounding connective tissues to analyze the layered relationship between the inferior extensor retinaculum (IER) and the subtalar joint capsule. Additionally, we histologically analyzed the tarsal canal and the medial and lateral sides of the tarsal sinus using Masson’s trichrome staining in 3 ankles. Results: The medial and intermediate roots of the IER and interosseous talocalcaneal ligament (ITCL) were located in the same layer and were connected to each other, between the capsules of the posterior talocalcaneal and talocalcaneonavicular joints. The intermediate root of the IER and the cervical ligament (CL) had adjacent attachments on the tarsal sinus, and synovial tissues originating from the joint capsules filled the remaining area in the tarsal canal and sinus. Conclusion: We determined that the tarsal canal and sinus tarsi contained 3 layered structures: the anterior capsule of the posterior talocalcaneal joint, including the anterior capsule ligament; the layer of ITCL and IER; and the posterior capsule of the talocalcaneonavicular joint, including the CL. Clinical Relevance: The results of this study may help with the understanding of the pathomechanism of subtalar instability and sinus tarsi syndrome, resulting in better treatment.

Introduction: Lifestyle changes (LC) influence peripheral blood pressure (BP) in pre-hypertensive (PH) individuals; the behavior of central systolic BP (CBP) in respect to LC is not fully known. However, pre-hypertension cardiovascular risk is similar to mild hypertension and can be associated with changes in the endothelial function thereby altering the CBP. Objective: Thus, to demonstrate the influence of LC on the peripheral and the central blood pressure in PH individuals.Methods: Fifty-six PH patients were studied before and after three months of LC (Dash diet and aerobic exercises). The CBP was measured by tonometry of the radial artery before and after LC.Results: The mean age of the study population was 48 ± 10.8 years. There were significant reductions in peripheral systolic pressure (127±8.1 vs. 122 ± 9.2, P=0.003), in the body mass index (29.0±4.6 vs. 28.5±4.6, P=0.001) and the waist-hip ratio(0.91 ± 0.07 vs. 0.89 ± 0.06, P=0.0007) and also in the central systolic pressure (113±10.7 vs. 107±10.9, P=0.0001) after three months of LC.Conclusion: Lifestyle changes promote improvement in peripheral and central BP in PH individuals.Aconselhamento sobre mudanças no estilo de vida reduz a pressão arterial central em indivíduos pré-hipertensos: um estudo de intervençãoIntrodução: Aconcselhamento para Modificação no estilo de vida (MEV) influencia diretamente a pressão arterial periférica em indivíduos pré-hipertensos. O comportamento da pressão sistólica central (PSC) em relação à MEV não está plenamente conhecido. Além disso, a pré-hipertensão (PH) oferece risco cardiovascular semelhante ao de um hipertenso leve e pode estar associado com alterações da função endotelial alterando a PSC.Objetivo: Demonstrar a influência da MEV com exercício físico e dieta alimentar em parâmetros antropométricos e hemodinâmicos, incluindo a PSC, em indivíduos pré-hipertensos.Métodos: Foram estudados 56 pacientes com PH antes e após 3 meses de MEV. A PSC foi avaliada utilizando-se um sistema de tonometria da artéria radial antes e após a MEV.Resultados: A média de idade da população estudada foi 48±10,8 anos. Houve redução significativa na PAS (127±8,1 para 122±9,2; p=0,003), PAD (75±7,4 para 72±7,7; p=0,003), PAM (92±7,0 para 89±7,6; p=0,002), IMC (29,0±4,6 para 28,5±4,6; p=0,001) e na relação C/Q (0,91±0,07 para 0,89±0,06; p=0,0007) após 03 meses de MEV. Também se observou redução da PSC (113±10,7 para 107±10,9; p=0,0001) após três meses de MEV.Conclusão: A MEV promoveu melhora pressão arterial periférica e central de indivíduos pré-hipertensos.

Background: Reduced vaginal mucus to dyspareunia (pain during intercourse) is often experienced by perimenopausal women. This decreases sexual drive and awakening in women who influence sexual quality with their partner. One of the body and mind intervention exercises in premenopausal women is loving yoga. This study aims to find out the effectiveness of loving yoga against the sexual function of perimenopausal women. Methods: This type of research is a quantitative experiment with a one-group pretest-posttest design approach. Research by giving loving yoga intervention for four weeks (with intensity twice a week). Loving yoga movement focuses on kegel gymnastics and pelvic muscle movements, such as plank movement, upward dog, happy baby, downward-facing dog, cat-cow, pigeon, cobbler, leg-up-the-wall, reclining-big-toe, and bridge. Researchers measured the sexual function in 30 women by purposive sampling with inclusion criteria were aged 40-50 and still sexually active before and after loving yoga using the Female Sexual Function Index (FSFI) questionnaire. Analyze data using paired sample T-test. Results: This study result is seen from the mean value of 14.33, which means the FSFI score ≤ 26.5. While after complementary therapy loving yoga, the mean value of respondents is 30.13 or an FSFI score ≥ of 26.5, which means no sexual dysfunction. Based on the calculated Paired T-Test variables, the sexual function is obtained at the value of –28,748 with a significance value of < 0,000 (p < 0,05). Conclusion: Loving yoga has an influence 28,748 times on changes in the sexual function in perimenopausal women.
