Pelvic floor muscle strength evaluation in different body positions in nulliparous healthy women and its correlation with sexual activity

Objective: The aim of this study was to assess pelvic floor muscle (PFM) strength in different body positions in nulliparous healthy women and its correlation with sexual activity.Materials and Methods: Fifty healthy nulliparous women with mean age of 23 years were prospectively studied. Subjective evaluation of PFM was assessed by transvaginal digital palpation (TDP) of anterior and posterior areas regarding the vaginal introitus. A perineometer with inflatable vaginal probe was used to assess the PFM strength in four different positions: supine with extended lower limbs (P1); bent-knee supine (P2); sitting (P3); standing (P4).Results: Physical activity, 3 times per week, was reported by 58% of volunteers. Sexual activity was observed in 80% of women and 82% of them presented orgasm. The average body mass index (BMI) was 21.76 kg/m(2), considered as normal according World Health Organization (WHO). We observed that 68% of volunteers were conscious about the PFM contraction. TDP showed concordance of 76% when anterior and posterior areas were compared (p = 0.00014). There was not correlation between PFM strength and orgasm in subjective evaluation. The PFM strength was significantly higher in standing position when compared with the other positions (p < 0.000). No statistical difference was observed between orgasm and PFM strength when objective evaluations were performed.Conclusions: There was concordance between anterior and posterior areas in 76% of cases when subjective PFM strength was assessed. In objective evaluation, higher PFM strength was observed when volunteers were standing. No statistical correlation was observed between PFM strength and orgasm in nulliparous healthy women.

Concepção morfológica de fórceps, para intervenção no paciente em posição supina e o operador sentado

Ergonomics, the science of working rationalization, seeks the best relationship between man and his working tools. In Dentistry, ergonomics is present as for the professional working correctly seated, in functional comfort, intervening of supine position patient, by means of suitable equipment and instrument. Nowadays, dental equipment is justly rationalized; however, some instruments should take shape, in order to adapt those requirements. The hand tool design should permit a comfortable, non-slip and safe handling. Thus, anatomical details, the correct position of the operator for its use and specific characteristics of application should be taken into account. The instrument under analysis - forceps - was conceived according to these requirements along with a new alveolar tooth extraction technique, based on electromyographic and biomechanical studies. The morphology of the instrument, which makes possible a simple and natural kinetics of the operator, was obtained by changing the paradigm of the conventional cross-action instruments (whose grip is always on the arms of the tool), divesting the handle from the tool arm. This induced on anatomical conceiving of perpendicular handles to the extremity of the tool arm, resulting an efficient and effective instrument, according to indicated on its experimental phase

Variabilidade da frequencia cardíaca em fase crônica de lesão cerebrovascular

The stroke, cause of morbidity and mortality, has been associated with imbalance in the neural control of the heart, which contributes to the decrease in heart rate variability (HRV) and a prognostic factor for cardiacevents and arrhythmias. The aim of this study was to in investigate the autonomic modulation of heart rate of men suffering from lesions stroke in chronicphase. Eight menaged 58.62 ± 2.88 years, 27.41 ± 5.33 kg/m2of bodymass índex, with paresis for at least six months were studied. Heart rate (HR) and RR intervals (iR-R) were recorded at rest in supine position for 10 minutes. Geometric índices of the Poincaré plot were calculated: SD1, associatedwith vagal activity; SD2, associated with global activity but sympathetic predominance, and the relationship of both (SD1/SD2). Geometric index values in the sample: SD1 = 20,54 ± 9,90ms; SD2 = 36,80 ± 30,61ms; SD1/SD2 = 0,49 ± 0,04. The reference values from literature for healthy subjects are: SD1 = 19.6 ± 9.4ms e 22.8 ± 16.1 ms; SD2 = 43.2 ± 17.7 ms e 56.3 ± 12.3 ms; SD1/SD2 = 0.49 ± 0.21ms. Men in chronic phase of stroke haven't autonomic dysfunction analyzed by nonlinear method – Poincaré geometricíndices.

Influência do exercício resistido aplicado de forma aguda sobre a variabilidade da frequência cardíaca em jovens ativos saudáveis: análise por meio de índices geométricos

Introduction: The triangular index and the Poincaré plot (or Lorenz plot) are the best known indexes obtained from geometric methods. The triangular index (TINN, RRtri) represent the global variability of the subject and SD1, which reflects the parasympathetic component, SD2, index of global variability and its relationship (SD1/SD2) are obtained from the Poincaré plot. Despite the literature showing changes in the cardiovascular system during and after the resistance exercise (RE), aspects related to autonomic modulation of heart against these conditions have not been explored yet, so it is important to evaluate this behavior. Objectives: Analyze the acute effects of RE on the cardiac autonomic modulation during recovery (REC) through analysis of geometric indices of heart rate variability (HRV), applied with different intensities and muscle groups in healthy and active young. Methods: Were evaluated 24 young, 22.25 ± 2.4 years and 24.47 ± 3.08 kg/m2, underwent an experimental protocol of five stages, in the first stage was conducted a test of one maximum repetition (1RM) in upper limbs (UL) and lower limb (LL), and the following steps were initiated interventions to 40 (E) and 80% (F) of 1RM. Considered for HRV analysis the periods: baseline and immediately after exercise, both in supine... (Complete abstract click electronic access below)

Estudo da motilidade gástrica em ratas prenhes diabéticas e não diabéticas

Several hormonal and physiological changes that occur during pregnancy directly affect gastrointestinal motility (GI), however, very little is known about the relationship between the electrical and mechanical activities of the stomach and its implications. The aim of this study was to compare the female sex hormones, with profiles of gastrointestinal motility using AC biosusceptometry (BAC) in pregnant rats. Seven female Wistar rats (weighing 250-350 g) were used and all procedures were approved by the local Ethics Committee of animal. Laparotomy was performed on anesthetized rats and a magnetic marker (3.5 mm in diameter and 3.0 mm height) was implanted in the distal stomach. After 10 days of recuperation, the mice were put to mate until confirmation of pregnancy. Fed animals were anesthetized (mg pentobarbital 30 / kg) and kept supine for recording the signal with a sensor 30 min BAC placed on the abdominal surface on days 0, 7, 14 and 20 of gestation. Statistical analysis was performed by Student's t test statistical Newman-Keuls and a P value of .05 was considered statistically significant. The frequency of contraction of the stomach was 74 mHz ± 3, 67 ± 7 mHz, 59 mHz ± 6 (p <0.05 vs day -1) and 71 ± 5 mHz on days -0, -7, -14, and -20, respectively. The values of 44 ± 15 pg / mL and 31 ± 9 pg / ml 25 ± 6 pg / ml, 22 ± 9 pg / ml on days -0, -7, -14 and -20, respectively, obtained by 17ß- estradiol were not statistically significant. The values of progesterone were 13 ± 6 pg / ml at 54 ± 15 pg / ml, 127 ± 42 pg / ml (p <0.05 vs day-1), 22 ± 13 pg / mL on day -0, - 7, -14 and -20, respectively. A linear correlation (Pearson's test) between the lower frequency gastric and increased levels of progesterone was 80% (p <0.0000001). Until then, the relationship between changes in motility and hormone were not described in detail, but with the work that we were able to demonstrate the high correlation between progesterone concentration ...
