An orthotic is a medical device designed to support, align, or improve the function of a body part, typically the feet, ankles, or lower limbs. These devices can help alleviate pain, correct deformities, and enhance mobility. Common types of orthotics include insoles, braces, and splints, which are often custom-made to fit an individual's specific needs. Orthotics are frequently used in the treatment of various conditions, such as plantar fasciitis, flat feet, and arthritis. They can be prescribed by healthcare professionals, including podiatrists and orthopedic surgeons, to provide relief and improve overall quality of life for patients.
