Filter by:The aim of the research project is to investigate the influence of resistance-training prescription (repetition duration, time under tension and training volume) and sex have on morpho-functional adaptations of upper and lower-body skeletal muscles. Twenty-four male and female university students were randomly assigned to one of two experimental groups, based on the repetition duration : "fast" group (with 1 second for eccentric and concentric phase) and "slow" group with prolonged duration of eccentric contraction (4 seconds for eccentric and 1 second concentric phase). At baseline and final measurement, cross-section area, one-repetition maximum and tensiomyography parameters (contraction time - Tc and radial displacement - Dm) of elbow flexors (biceps brachii) and knee extensors (4 quadriceps muscles) were evaluated.
The study consists in evaluating the neuromuscular response of the gastrocnemious muscles before and after a diacutaneous fibrolysis over the gastrocnemious muscles.
This study will compare the performance of a contraction monitor (tocometer) device developed by Fetal Life with standard tocometer devices. The study aims to test a uterine contraction monitor that can be applied by the patient to her abdomen and connected to her smart device to detect the frequency and duration of uterine contractions. Phase 1 will collect data for calibration of the monitor and for a noninferiority study comparing the Fetal Life uterine contraction monitor (tocometer) with standard tocometry devices. Phase 2 will be a feasibility study in which patients will position the monitor, connect to the corresponding Fetal Life app and measure their own uterine contraction activity. The study's hypothesis is that after calibration, the new monitor will reliably detect at least 95% of the number and duration of contractions detected by the standard monitor, and that the device will perform comparably whether applied by the patient or by research staff.
It is estimated that about 30% of women cannot voluntarily contract the pelvic floor muscles (PFM). PFM training (PFMT) represents the first therapeutic option for the treatment of female urinary incontinence (UI), however the inability to contract this muscle makes PFMT unfeasible. The primary objective of this project is to evaluate clinically the efficacy of intravaginal electrical stimulation associated with verbal instructions to provide the ability of women to contract voluntary their PFM. The secondary objective is to evaluate the UI prevalence and impact on quality of life.
The EUM (electrical uterine myography) (OB Tools, Israel) was tested and found to be reliable as a non-invasive method for evaluating uterine contractions and the fetal heart rate. It is safe and effective in monitoring uterine contractions. The investigators propose to perform a study to validate the accuracy and clinical usefulness of the EUM device by simultaneously monitoring obese patients with current method of external tocodynamometry with the EUM device. Providers will be blinded to the results of the EUM device. Caregivers will continue care as per current guidelines using the information obtained from the current monitoring methods. Information obtained from the EUM devices will not be used to determine the clinical course of action.
