Back and lumbar supports are devices designed to provide support to the lower back region and improve posture. They are typically made of lightweight, breathable materials and can be worn underneath or over clothing. Back and lumbar supports work by helping to maintain the natural curve of the spine and providing additional support to the muscles and ligaments of the lower back. They may also help to relieve pain and discomfort associated with poor posture or injuries such as muscle strains or herniated discs. Back and lumbar support can be particularly beneficial for individuals who spend a long time sitting or standing, as well as those who engage in physical activities that place a significant amount of strain on the lower back. They are often recommended by healthcare professionals as part of a comprehensive treatment plan for back pain and related conditions.
