Gait and Computerized Dynamic Posturography (CDP) Aspects in Early Progressive Supranuclear Palsy (PSP) - A Case Report

Abstract

BACKGROUND: Posture and gait instability may cause of morbidity in individuals with progressive supranuclear palsy (PSP). OBJECTIVE: To quantitatively measure balance control by using computerized dynamic posturography (CDP) and to assess gait analysis in early PSP.CASE REPORT: She was evaluated for Berge balance scale, Functional Independence Measure (FIM) and postural stability using CDP device in early PSP with still able to walk or stand unassisted. Also, Gait analysis was conducted using an 8 M-camera Vicon 612 data capturing system set. Berge balance scale improved from 41/56 to 48/56. The score of FIM improved from 71/126 points to 95/126 points in early PSP. In CDP analysis, there was a decrease of composite equilibrium score (38 %). There was an increase of composite equilibrium score (59%) after three months of treatment. In gait analysis, there was no difference of gait parameters after three months of treatment in early PSP.CONCLUSIONS: Both CDP and gait analysis are important quantitative tools in the assessment of posture and gait instability as well as allow for early disclosure of the failure of the postural control system in early PSP.
