Core and Pelvic Stability Issues (affecting posture, back pain, or movement) occur when the muscles that support the spine, pelvis, and trunk are weak, poorly coordinated, or unable to provide adequate stability during movement. These muscles play a vital role in maintaining good posture, protecting the spine, and ensuring efficient movement during everyday activities. Weakness or dysfunction can develop following injury, pregnancy, surgery, prolonged inactivity, poor posture, or repetitive strain, leading to lower back pain, pelvic discomfort, reduced balance, and difficulty with walking, lifting, bending, or sporting activities. Individuals may also experience muscle fatigue, poor movement control, and an increased risk of recurring injuries. Early assessment and appropriate treatment are essential to identify the underlying cause and restore normal function. Physiotherapy focuses on improving core strength, pelvic stability, posture, balance, flexibility, and movement patterns through targeted exercises, manual therapy, and functional training. A personalised rehabilitation programme helps reduce pain, enhance spinal and pelvic support, improve mobility, prevent future injuries, and enable patients to return safely to work, sports, and everyday activities with greater strength, stability, and confidence.
