Analysis of dynamic posture in patients with early Parkinson disease / 中国神经精神疾病杂志

ABSTRACT

Objective To quantitatively analyze the dynamic posture in patients with early stage Pakinson disease (ESPD) by using dynamic posture equilibrium equipment. Method Thirty two ESPD patients were recruited in this study, in which, 10 was at Hoehn-Yahr stage 1, 9 at Hoehn-Yahr stage 1.5, 13 at Hoehn-Yahr stage 2. Thirty two age and gen?der matched healthy subjects served as a control group. The sensory organization test (SOT), motion coordination test (MCT), adaptive test (ADT), walk across were performed in those two groups using NeuroCom smart dynamic posture equipment. Results The average composite scores for SOT were 64 and 79 in ESPD patients and control group(P=0.032). The eqilibrium ratio of vision and vestibular sense were obviously lower in ESPD patients than in the control group ( 73.55±3.15 vs. 82.45±3.53, P=0.037;45.25±4.25 vs. 66.43±6.98, P=0.021). MCT showed that ESPD patients had a higher abnormality ratio of centre-of-gravity position compared with controls ( 70.3%vs. 7% )(P<0.001). ESPD pa?tients had 33% and 57% abnormality in ADT and Walk Across, which were obviously higher compared with control group (P<0.001). Conclusions ESPD patients have different degrees of posture disorders and posture equilibrium assess?ment at early stage is beneficial to rehabilitation training.
