Tinel's: patients wrist is tapped. if the patient feels shooting electricity/pain to the thumb or index finger, it indicates a compressed median nerve.

Phalen's: The patient is asked to hold their wrist in complete and forced flexion (pushing the dorsal surfaces of both hands together) for 30–60 seconds.  Symptoms such as burning, tingling or numb sensation over the thumb, index, middle and ring fingers convey a positive test result and confirms carpal tunnel syndrome.

Durken's:  applying direct pressure on the wrist (at the carpal tunnel) to compress the median nerve to elicit symptoms (burning, tingling, numb sensation over the thumb, index, middle, or ring fingers).  Is the most sensitive test for diagnosing CTS.

---------

Hoffman's: to test for corticospinal problem (its like a Babinski's of the upper extremity).  Done by tapping the nail or flicking the terminal phalanx of the third or fourth finger. A positive response is seen with flexion of the terminal phalanx of the thumb and indicates Upper motor neuron dysfunction.

Hand shaking sign:  Symptoms of CTS decrease when vigorously shaking hand.
