| 目的 研究脑卒中偏瘫患者站立平衡功能与步行能力的相关性。 方法 选取可独立步行10m以上的脑卒中偏瘫患者88例并将其纳入患者组，同时选取相匹配的健康老年人纳入对照组。采用AL-600型步态与平衡功能训练评估系统对2组受试对象进行站立平衡功能及步态测试，步态检测指标包括步宽、步速、双下肢步长不对称比（SLA）、摆动期时间不对称比（SWTA）及站立期时间不对称比（STA），平衡功能检测指标包括足底压力中心总轨迹长（COPD）、足底压力中心在左右方向的平均偏移（COPD-X）、足底压力中心在前后方向的平均偏移(COPD-Y)。采用t检验比较2组对象步态及平衡指标间差异，同时采用Pearson检验分析2组对象步态与平衡参数间的相关性。 结果 患者组对象步宽［（14.45±4.17）cm］、COPD［（66.75±29.04）cm］、COPD-X［（2.04±1.41）cm］、COPD-Y［（2.48±1.28）cm］、SLA（1.30±0.46）、SWTA（1.65±0.67）及STA（1.18±0.16）均较对照组明显增加（P<0.05）,步速［(37.64±18.29)cm/s］则较对照组明显减小（P<0.05）；患者组对象COPD-X与步速、步宽、SLA、SWTA呈轻度至中度相关（P<0.05）；COPD-Y与步宽呈轻度相关（P<0.05）。 结论 脑卒中偏瘫患者其站立平衡功能与步宽、步速、步态时空不对称参数间具有相关性，并且以左右方向平衡功能指标(如COPD-X)与步态参数间的相关性较为显著。 |

| Objective To study the relationships between the standing balance and walking ability of hemiplegic stroke survivors. Methods Eighty-eight post-stroke hemiplegic patients who could walk independently for more than 10 metres were selected into a patient group, while 88 healthy counterparts were recruited into a control group. Descriptors of the gait and balance function of both groups were collected using a gait and balance training and evaluation apparatus (Model: AL-600). The gait parameters were step width, walking speed, step length asymmetry (SLA), swing time asymmetry (SWTA) and stand time asymmetry (STA). The balance parameters studied were total trajectory length of the center of plantar pressure (COPD), the average left and right deviation of the center of plantar pressure (COPD-X) and the average anterio-posterior deviation of the center of plantar pressure (COPD-Y). Differences in indexes of gait and balance function between the two groups were analyzed using t-tests, and the relationships between the gait and balance indicators were analyzed using Pearson correlation coefficients. Results The walking speed, step width, COPD, COPD-X, COPD-Y, SLA, SWTA and STA of the patient group ［(37.64±18.29)cm/s, （14.45±4.17）cm, （66.75±29.04）cm, （2.04±1.41）cm, （2.48±1.28）cm, (1.30±0.46),（1.65±0.67） and （1.18±0.16）, respectively］ all increased significantly more compared to the control group ［(90.76±14.72)cm/s, （8.70±2.62）cm, （27.84±6.54）cm,（1.30±0.53）cm,（1.68±0.40）cm,（1.07±0.06）,（1.07±0.08） and （1.05±0.06）,respectively］, though the walking speed was significantly slower than that in the control group (P<0.05). The patient group′s average COPD-X showed slightly and moderately negative correlation with their walking speed, step width, SLA and SWTA (P<0.05). COPD-Y was weakly related with step width (P<0.05). Conclusion The standing balance of hemiplegic patients after stroke is related to their walking speed, step width and gait asymmetry. Especially significant correlation is observed between standing balance parameters such as COPD-X and gait parameters. |
