- Phalens Test
- Wrist Flexion Test
- Phalen Maneuver
- Median Nerve Compression Test
- Reverse Phalen Test
Purpose
- Evaluate the Carpal Tunnel as a cause of hand and wrist pain
Description
- The patient is seated
- Both wrists are maximally flexed with the dorsal sides of each hand touching in a "reverse prayer" formation
- Patient needs to actively apply pressure to dorsal sides
- This position must hold this position for 30 - 60 seconds
- This position increases pressure in the carpal tunnel
- Positive Test
- Reproduction of their symptoms
- Paresthesia (burming, tingling, numbness)
Modification
- Patient flexes wrists separately
- Patient places dorsal hands against each other
- Examiner flexes patient’s wrists

- The filament (see image, arrow) is applied perpendicular to the skin surface until it bends.
