三种量表评定脑卒中急性期患者姿势控制能力的分析研究

A study about three postural assessment scales on postural control in patients with stroke in acute stage

目的探讨3种量表在评定脑卒中急性期患者姿势控制能力方面的应用情况。方法对45例脑卒中急性期患者分别采用脑卒中患者姿势评定量表（PASS）、Fugl—Meyer平衡量表（FM—B）及Berg平衡量表（BBS）对其姿势控制能力进行评定。所有病例均评定3次，评定时间分别为脑卒中起病后1周内、起病第3周时及出院前。选用Spearman统计法分析3种量表间的相关性；并同时计算3种量表的地板效应及天花板效应。结果PASS与FM—B及BBS间均具有高度相关性（r=0.867—0．957，P〈0．01）；在本研究各次评定中，PASS无明显的地板效应和天花板效应，而FM-B和BBS在第1次评定时均存在明显的地板效应（FM—B为26．6％．BBS为26．6％）。结论PASS与FM—B及BBS均能客观反映脑卒中急性期患者的姿势控制能力，而且PASS还能对脑卒中患者的卧位姿势控制能力进行评定，故在评定脑卒中急性期患者姿势控制能力方面，PASS优于FM—B和BBS。

Objective To compare three postural assessment scales（PAS） on postural control（PC） in patients with stroke in acute stage. Methods Forty-five patients with stroke were assessed with the postural assessment scale for stroke patients （PASS） , the balance sub scale of the Fugl Meyer movement assessment （FM-B） and the Berg Balance Scale （BBS） at 1 w and 3 w post-stroke, before discharging from hospital. The correlation between PASS, FM-B and BBS was examined with Spearman correlation coefficients, and floor and ceiling effects were calculated. Results There was positive correlation among PASS, FM-B and BBS （ r = 0. 867 - 0. 957 ,P 〈 0.01 ）, There were obvious floor and ceiling effects in FM-B and BBS （26.6% , 26.6% ） in the first assessment, but not in PASS. Conclusion The ability of PC in stroke patients in acute stage could be evaluated with PASS, FM-B and BBS, and PASS is the best suitable among above scales.
