Recognition of gait disturbances in patients with normal pressure hydrocephalus using a computer dynography system.
Gait and body balance disturbances are important clinical problems in patients with normal pressure hydrocephalus (NPH). They affect patients' locomotion and lead to a higher risk of falls. The gait pattern may be described as durations of the single and double support and of a stance phase. The aim of the present study was to apply the pattern recognition methods for the evaluation of gait disturbances in patients with NPH before and after neurosurgical treatment (shunt implantation). The results indicate that the parameters measured with a Computer DynoGraphy (CDG) system may effectively differentiate changes of gait in patients with NPH.
