Diagnosis & Tests
During a physical examination, the doctor may find:
- Numbness in the palm, thumb, index finger, middle finger, and thumb side of the ring finger
- Weak hand grip
- Tapping over the median nerve at the wrist may cause pain to shoot from the wrist to the hand (this is called Tinel’s sign)
- Bending the wrist forward all the way for 60 seconds will usually result in numbness, tingling, or weakness (this is called Phalen’s test)
Tests may include:
- Electromyography
- Nerve conduction velocity
- Wrist x-rays should be done to rule out other problems (such as wrist arthritis)
