Clinical presentation of symptoms and physical examination are used to diagnose median nerve compression. For instance, a physical exam may confirm diagnosis through the help of the Tinel sign and Phalen maneuver. The Tinel sign is positive if tingling is experienced when pressure is applied to the wrist. The Phalen maneuver is positive if tingling is experienced when the wrist is placed at a 90° angle. With median nerve injury, specifically due to CTS, both the Tinel sign and Phalen maneuver will likely be positive.  When treating median nerve compression, splinting is considered a first-line treatment. Other conservative, or traditional, treatments can include physical therapy, yoga and therapeutic ultrasound. Therapeutic ultrasound uses ultrasound technology to speed up the rate of healing and enhance the quality of repair. In some cases, oral steroids or the injection of steroids may also be considered for severe pain relief. Individuals with CTS may also be advised to make ergonomic adjustments to their workspace and computer space, such as wrist and elbow supports to help relieve pain.  Patients with severe pain of more than four to six months and no relief from conservative treatments may be offered surgical decompression.
