Filter by:The aim of this study was to investigation of knee position sense, balance, and dual task performance in different phases of menstrual cycle in females with multiple sclerosis. Multiple sclerosis (MS) is a chronic inflammatory disease of the central nervous system (CNS) affecting young people and leading to demyelination and neurodegeneration. MS affects females more than males with a ratio approximately of 3:1. Important gender differences in progression and inflammatory activity of disease have been observed. Sex hormones have been thought to play an important role in this condition. It is worth noting however that sex hormones not only affect reproduction (menses/pregnancy), they also have direct effects on the nervous and immune system. In the neurologic group, especially in MS patients, it is well known that disease activity, course, and symptoms can be influenced by hormonal fluctuations in different phases of the menstrual cycle. Previous studies have reported that the variation of estrogen and progesterone during the menstrual cycle may have an effect on several neurological functions. However, these studies are mostly subjective, in the form of patient reports and in limited numbers. Smith and Studd reported that there was a premenstrual increase in disease severity as changes in the Th-1 / Th-2 balance occurred in association with decreased circulating estrogen. Withdrawal of hormones from damaged tissues that affect axonal conduction can explain the change in disease activity, course symptoms during the menstrual cycle in female with MS. For all these reasons,investigators think that different phases of menstrual cycle change position sense, balance, and dual task performance in females with MS. Considering hormonal fluctuations occurring in the menstrual cycle, is an important criterion for organizing the rehabilitation program and evaluation in terms of physiotherapy.
This is an observational longitudinal study to advance the understanding of menstrual cycle and gynecologic health conditions including PCOS, infertility and breast cancer.The study will be hosted within the Research app(available on App Store), which allows a user to find, enroll, and participate in Apple-supported health-related research studies.
This research project's objective is to investigate substrate metabolism behavior in response to the RT during different phases of the menstrual cycle.
The aim of the work is to assess the effect of the menstrual cycle on the biomechanical properties of the muscles. The study will be conducted among young women aged 20-25 with a regular menstrual cycle. During the test, muscle strength and muscle flexibility as well as activation times will be performed. The study will assess the effect of the stretching of the hamstring muscles on the biomechanical properties of the muscles in the different phases of the menstrual cycle.
Quitlines are efficient and cost-effective treatments for smoking cessation, yet little research has explored how to personalize and optimize quitline services for women. The goal of this project is to explore the feasibility and preliminary efficacy of a quitline intervention that considers the menstrual cycle as compared to standard care for cessation. If funded, the results of this study will directly inform future research on quitline smoking cessation interventions for premenopausal women, including a full scale clinical trial.
The aim of this study was to investigate the effects of menstrual cycle phases on recovery and cognitive function after general anesthesia.
The investigators aimed to investigate the effect of menstrual cycle phases on preoperative anxiety in women under general anesthesia.
The overall goal of this study is to examine the influence of the menstrual cycle on micronutrient concentrations and plasma volume in healthy, reproductive-age women with regular cycles. The investigators aim to quantify changes in micronutrient biomarker concentrations (zinc, copper, iron, and vitamin A) and plasma volume across the menstrual cycle in healthy women.
Measuring brain perfusion is biased by a inter- and intrasubject variability, caused by physiological and lifestyle factors. In this study, the investigators want to investigate the variations in cerebral perfusion and other brain parameters (grey matter, resting-state brain activity, brain connectivity and white matter diffusion) caused by the female sex hormones and hormonal contraception.
This study aims to use validated tools as well as new technology to examine changes in bleeding patterns among women who are initiating the copper T380A IUD.
