目的：探讨社区平衡与活动量表（CB&M）在社区卒中幸存者中的收敛效度、变化敏感性、下限和上限效应。第二个目标是确定CB&M和下肢运动恢复和strength.Design之间的相关性：效度研究。设置：两个大学为基础的研究centers.Participants：社区居住的人中风后（N=44; 24男，20女;平均年龄62.6 +/-12.6岁）。基线测量在卒中发作后3个月进行（98.6 +/-52.6天）;参与者在卒中后8个月重新评估（246.8 +/- 57.2d）.干预措施：不适用.主要结果指标：CB&M、贝格平衡量表（BBS）、定时起身和行走（TUG）、Chedoke McMaster卒中评估（CMSA）腿部和足部损伤量表，使用测力计测量下肢屈肌和伸肌群的同心双侧等速力量。CB&M、BBS和TUG之间的关联程度和标准化反应均值（SRM）分别用于检查收敛效度和变化敏感性。
Objectives: To examine the convergent validity, sensitivity to change, floor and ceiling effects of the Community Balance and Mobility Scale (CB&M) in community-dwelling stroke survivors. The secondary objective was to determine the correlations between the CB&M and lower-limb motor recovery and strength.Design: Validity study.Setting: Two university-based research centers.Participants: Community-dwelling persons after stroke (N=44; 24 men, 20 women; mean age, 62.6 +/- 12.6y). Baseline measures were taken 3 months after the onset of stroke (98.6 +/- 52.6d); participants were reassessed 8 months post-stroke (246.8 +/- 57.2d).Interventions: Not applicable.Main Outcome Measures: CB&M, Berg Balance Scale (BBS), Timed Up & Go (TUG), Chedoke McMaster Stroke Assessment (CMSA) Impairment Inventory for leg and foot, concentric bilateral isokinetic strength of the lower-limb flexor and extensor muscle groups using a dynamometer. The magnitude of the associations and the standardized response means (SRMs) among the CB&M, BBS, and TUG were used to examine the convergent validity and sensitivity to change, respectively.Results: Moderate to high convergent validities (p=.70 to .83, P
