Bunnell littler test
The MCP joint is held in an extended position and the therapist passively flexes the PIP making note of the available range. The test is then repeated with the MCP joint flexed. If no change in motion is detected between the two tests, then capsular restriction at the PIP joint is implicated. If the motion increases when the MCP joint is flexed, then lumbricale muscle tightness is implicated
Finkelstein test
DeQuervain's Tenosynovitis
Scaphoid shift test

Percussion test for finger
The patient extends their finger, and the physical therapist applies a forceful tap to the tip of the finger. If the patient experiences pain during the test, a fracture diagnosis is likely

checking for sprain in collateral ligaments - push joint laterally
