Flowchart of the process to identify probable idiopathic normal pressure hydrocephalus (iNPH) and definite iNPH in 137 possible iNPH patients performed tap tests.  Out of 137 possible iNPH patients who performed tap tests, 129 were evaluated for their gait function on all the 1st, the 3rd, and the 7th days after the tests. Among these 129 cases, 108 showed gait improvement on either the 1st, the 3rd, or 7th days, and they were diagnosed with probable iNPH. Twelve patients with DESH’s image findings were also diagnosed with probable iNPH but did not improve their gait function on any of the 1st, 3rd, or 7th days. Out of 120 probable iNPH patients, 84 underwent shunt surgery, and 78 were diagnosed with definite iNPH
