The goal of this clinical trial is to to evaluate various gait parameters by a sensor-embedded smart insole before and after the cerebrospinal fluid (CSF) tap test in idiopathic normal pressure hydrocephalus (iNPH) patients. The main questions it aims to answer are: * Does the CSF tap test enhance gait and balance parameters in participants? * Does the CSF tap test enhance cognitive and urinary symptoms in participants? Researchers will compare pre- and post-CSF tap test gait and balance parameters by a sensor-embedded smart insole. Participants will: * Participate in physical function assessments including the 10-meter walk test, Timed Up and Go test, and Berg Balance Scale wearing sensor-embedded smart insoles before and after the CSF tap test. * Complete survey about cognitive and unary symptoms before and after the CSF tap test.

Timed up and go test (TUG)
Timeframe: This session will be performed at baseline and at end-point. A baseline assessment will be conducted within 24 hours before the CSF tap test, and an end-point assessment will be conducted within 24 hours after the CSF tap test.
10 meter walk test (10MWT)
Timeframe: This session will be performed at baseline and at end-point. A baseline assessment will be conducted within 24 hours before the CSF tap test, and an end-point assessment will be conducted within 24 hours after the CSF tap test.
Berg balance scale (BBS)
Timeframe: This session will be performed at baseline and at end-point. A baseline assessment will be conducted within 24 hours before the CSF tap test, and an end-point assessment will be conducted within 24 hours after the CSF tap test.
