The Brazilian Portuguese version of the Pregnancy Mobility Index: Cross-cultural adaptation and psychometric evaluation - a validation study.

Background: The Pregnancy Mobility Index (PMI) was developed to assess mobility in pregnant women in the Netherlands. At present, no similar questionnaire is available in Brazil.

Objective: The present study aimed to translate, cross-culturally adapt, and evaluate the psychometric properties of a Brazilian PMI.

Verbal and Visual Feedback Immediately Affect the Electromyographic Activity of Female Pelvic Floor Muscles.

Objective: The purpose of this study was to assess the immediate effect of verbal and visual feedback on pelvic floor muscles (PFM) in nulliparous women without pelvic floor dysfunction.

Methods: In this observational, single-assessor, cross-sectional study, 45 female university students were evaluated using bidigital vaginal palpation and vaginal surface electromyography (EMG). EMG assessments were performed at 2 time points (T1 and T2).

Effects of Auriculotherapy on treatment of women with premenstrual syndrome symptoms: A randomized, placebo-controlled clinical trial.

Objective: This study aimed to investigate the effect of auriculotherapy on the intensity of physical and mood Premenstrual syndrome (PMS) symptoms.

Design: Single-blind randomized, placebo-controlled clinical trial.

Setting: Federal University of Parana, Curitiba, Brazil.

Immediate analgesic effect of two modes of transcutaneous electrical nerve stimulation on patients with chronic low back pain: a randomized controlled trial.

Objective: To compare and assess the immediate analgesic effects of conventional and burst transcutaneous electrical nerve stimulation in patients with chronic low back pain.

Methods: We conducted a three-arm single-blinded randomized controlled trial. A total of 105 patients with non-specific chronic low back pain aged between 18 and 85 years were randomly assigned into the following groups: Placebo Group (sham electrical stimulation), Conventional TENS Group (continuous stimulation at 100Hz for 100µs with sensory intensity), and Burst TENS Group (stimulation at 100Hz modulated at 2Hz for 100µs with motor-level intensity).

Immediate analgesic effect of transcutaneous electrical nerve stimulation (TENS) and interferential current (IFC) on chronic low back pain: Randomised placebo-controlled trial.

Objective: To compare the immediate analgesic effect of transcutaneous nerve stimulation (TENS) and interferential current (IFC), with different combinations of parameters, in individuals with chronic low back pain (CLBP).

Methodology: 280 individuals with CLBP were included in the study, both genders, randomized in 8 groups: GI2KHz/100Hz, GI2KHz/2Hz, GI4KHz/100Hz, GI4KHz/2Hz, placebo interferential group (GIP), GT100Hz, GT2Hz, and placebo TENS group (GTP). All individuals underwent a single application of TENS or IFC for 30min.

Wound healing treatment by high frequency ultrasound, microcurrent, and combined therapy modifies the immune response in rats.

Background: Therapeutic high-frequency ultrasound, microcurrent, and a combination of the two have been used as potential interventions in the soft tissue healing process, but little is known about their effect on the immune system.

Objective: To evaluate the effects of therapeutic high frequency ultrasound, microcurrent, and the combined therapy of the two on the size of the wound area, peritoneal macrophage function, CD4+ and CD8+, T lymphocyte populations, and plasma concentration of interleukins (ILs).

Method: Sixty-five Wistar rats were randomized into five groups, as follows: uninjured control (C, group 1), lesion and no treatment (L, group 2), lesion treated with ultrasound (LU, group 3), lesion treated with microcurrent (LM, group 4), and lesion treated with combined therapy (LUM, group 5).

Microcurrent application as analgesic treatment in venous ulcers: a pilot study.

This study aimed to evaluate the effect of microcurrent electrical stimulation on pain and area of venous ulcers. In a pilot study for a single-blind controlled clinical trial, carried out at an outpatient clinic during four weeks, 14 subjects with venous ulcers (mean age 62±9 years) were divided in two groups: microcurrent (n=8) and control group (n=6). Pain (by Visual Analogue Scale) and the ulcer area were measured by planimetry.
