Abstract

INTRODUCTION and AIM Gait disturbance is a very common and disabling symptom of idiopathic normal pressure hydrocephalus (iNPH), and it is often the first sign to appear. The other classical symptoms are urinary incontinence and cognitive dysfunction. Shunt surgery aimed at removing the excess of cerebrospinal fluid (CSF) may improve the iNPH patient condition, and it is routinely applied to selected patients after a careful clinical assessment of the potential risks and benefits following the surgery. To improve the patient selection for shunting, clinicians may perform a taptest (TT), i.e., they remove 30-50 ml of CSF by lumbar puncture to obtain a temporary drainage. Improvements in gait after TT is often used to prognosticate shunt responsiveness. Patients are classified as tap-test responders or non-responders, depending on presence or absence of transient gait improvements after CSF removal. Gait improvements are usually evaluated by clinicians in a subjective way or performing the 10-m test. Instrumented gait analysis may be an important tool to assess gait changes after TT, thus helping the clinician in a better selection of the candidates for shunt surgery.The aim of this study is to propose an objective method, based on gait data, to classify TTresponders and non-responders.
