Study evaluates movement selectivity improvement in hemiparetic post-stroke patients after balance training.
Study included 26 patients and 15 healthy subjects (control group C). Patients were divided into two groups with 20-day balance training (A) and without (B). Normal standing weight distribution was expressed in percentages, center of feet pressure (COP) sway velocities were evaluated in anterior-posterior and medio-lateral (Y, X) directions for normal standing with eyes open and closed (EO, EC) and for tandem. Brunnström scale assessed movement selectivity.
Weight distribution dissymmetry (Δ10%) was found. It was reduced (Δ2%) after training in group A. COP were higher for X direction (±6mm/s vs ±12mm/s) in normal standing. Difference (±12mm/s) was found for Y in tandem. Brunnström score increased in group A from 0.3 to 0.6. It was negatively correlated with average COP for EO and EC in Y and X and for tandem in X.
Training reduces weight-bearing dissymmetry and improves movement selectivity.
研究评估平衡训练后中风后偏瘫患者的运动选择性改善情况。
研究纳入26例患者和15名健康受试者（对照组C）。患者分为两组，一组进行为期20天的平衡训练（A组），另一组不进行训练（B组）。正常站立时的体重分布以百分比表示，通过评估睁眼和闭眼（EO、EC）以及单脚站立时前后和内外侧（Y、X）方向的足底压力中心（COP）摆动速度。采用Brunnström量表评估运动选择性。
发现体重分布不对称（Δ10%）。A组训练后该不对称性降低（Δ2%）。正常站立时X方向的COP较高（±6mm/s对±12mm/s）。单脚站立时Y方向存在差异（±12mm/s）。A组的Brunnström评分从0.3提高到0.6。其与EO和EC时Y和X方向以及单脚站立时X方向的平均COP呈负相关。
训练可减轻负重不对称并改善运动选择性。
