Background: Two-thirds of pregnant women suffer from low-back pain during pregnancy, which leads to negative effects on quality of everyday life. According to the literature, an 8- to 12-week program of adapted physical activity during pregnancy has proven its efficacy in treatment of low-back pain and functional disability. Stretching Postural is a nondynamic technique using muscular contractions and stretches that act mainly on the back and that can be practiced alone.

Objective: This study aimed to assess the effect of an 8-week program of standardized Stretching Postural postures in low-risk pregnant women suffering from low-back pain.

Study Design: This was an open-label, randomized, controlled trial in 1 French university hospital. Women with a singleton low-risk pregnancy between 15 and 32 weeks of gestation and with back, lumbar, or sacroiliac pain were randomly assigned (1:1) to either undergo an 8-week program of standardized Stretching Postural with basic advice (intervention group) or to receive basic advice only (control group). Both groups received ergonomic advice and encouragement to practice physical activity. The primary endpoint was the pain assessment at 8 weeks (defined by the mean pain level estimated by women in the previous week, scored on a numeric scale from 0 to 10). Secondary endpoints were pain after 4 weeks of follow-up, quality of life (12-item Short Form Survey), satisfaction (Patient Global Impression of Change), and delivery outcomes. The main analysis was intention-to-treat.

Results: From January 2019 to August 2020, 60 women were randomized: 30 were assigned to the intervention group and 30 to the control group. The mean level of pain at 8 weeks was significantly lower in the intervention group than in the control group (1.6±1.4 vs 4.1±2.2; P<.01). The mean 12-item Short Form Survey scores were significantly higher in the posture group than in the control group (Physical Component Score, 45.7±7.8 vs 37.4±8.5; P<.01; Mental Component Score, 54.3±5.8 vs 50.4±7.1; P=.04), and the Patient Global Impression of Change score was also significantly higher (6.1±1.5 vs 3.9±2.3; P<.01). No adverse effects were found.

Conclusion: Stretching Postural appears to be a safe and efficient nondrug therapy to treat low-back pain during low-risk pregnancy.

Over the past 20-30 years, numerous studies have expanded our understanding of the connective components within the human musculoskeletal system. The term "fascia" and, more specifically, the "fascial system" encompass a variety of connective tissues that perform multiple functions. Given the extensive scope of the topic of fascia and the fascial system, which cannot be fully addressed in a single article, this work will focus specifically on the role of fascia in tension transmission (mechanotransduction).

Yoga has been recommended as a complementary management strategy for women with chronic pelvic pain (CPP), but many women lack access to specialized yoga instruction for this indication, and few data are available to evaluate changes in CPP with yoga. This feasibility trial evaluated the acceptability and tolerability of a remotely delivered yoga program for CPP in women and examined data quality and interpretability for measures of pelvic pain intensity and impact with yoga instruction. Ambulatory women with CPP were recruited from northern California in 2020-2022 and randomly assigned to a 2-month program involving twice weekly group classes delivered by videoconference supplemented by individual practice of pelvic yoga techniques versus a control program involving equivalent-time instruction and practice of nonspecific skeletal muscle stretching-strengthening exercises.

Central mechanisms of muscle tone regulation: implications for pain and performance.

Front Neurosci

December 2024

Department of Psychology and Communication, University of Idaho, Moscow, ID, United States.

Muscle tone represents a foundational property of the motor system with the potential to impact musculoskeletal pain and motor performance. Muscle tone is involuntary, dynamically adaptive, interconnected across the body, sensitive to postural demands, and distinct from voluntary control. Research has historically focused on pathological tone, peripheral regulation, and contributions from passive tissues, without consideration of the neural regulation of active tone and its consequences, particularly for neurologically healthy individuals.

Many pregnant women use cannabidiol (CBD) as a natural remedy to alleviate symptoms such as nausea, insomnia, anxiety, and chronic pain. As much as 20% of pregnancies in the USA and Canada may involve the use of CBD-only products. CBD crosses the placenta and may affect fetal development, potentially leading to neuropsychiatric conditions later in life.

Background And Purpose: Work-related musculoskeletal disorders (WMSDs) are an array of conditions affecting the human locomotor system, such as muscles, tendons, nerves, bones, and joints. It is related to physiological, kinesiological and biomechanical changes which result in pain, paresthesia, inflammation, weakness, tiredness, heaviness in limbs, fatigue, reduced range of motion and/or compression of peripheral nerves. The aim of this study was to investigate the therapeutic effects of positive (massage gum) or negative pressure (vacuum therapy) combined with laser on the health of workers with back pain, investigating pain intensity, shoulder mobility, spinal flexibility, life quality, and well-being.
