Abstract
Assessment of gait and posture as symptoms has been the primary concern in the diagnosis and treatment of normal pressure hydrocephalus (NPH), a disease in which there is excessive accumulation of cerebrospinal fluid (CSF) in the brain. Diagnosis of NPH is usually initiated by a high volume lumbar puncture (HVLP) followed by the evaluation of clinical response to removal of CSF. In this paper, we analyze the gait movement of a patient using inertial body sensor nodes and capture features pre and post HVLP. This method provides a quantitative measure of gait assessment. The features extracted from a patient's gait are found to strongly correlate with the assessment recorded manually by the physician conducting the study.
