Medical supports and braces are designed to stabilize or limit the mobility of a specific body part. This can help reduce arthritis pain or help a person heal from minor injury or surgery. Products like knee and elbow braces work by applying light compression and soothing warmth to the affected area. They can also be worn while playing sports to prevent injuries. Cervical collars support the neck and spine. They reduce the movement of your neck and head to help recover from trauma, surgery, or fractures. Be sure to consult with your doctor before treating any neck or joint injuries.
