Functional independence is often compromised after stroke and its restoration is one of the goals of stroke rehabilitation.
This study assessed the impact of balance on functional independence after stroke.
Ninety-five stroke patients undergoing physical rehabilitation at two health institutions in Nigeria participated in the study. Balance and functional independence were respectively assessed with the Berg Balance Scale and the Barthel Index. Binary logistic regression analysis was conducted to examine the independent impact of balance on functional independence while controlling for participants' age, sex, side of hemiparesis and post-stroke duration.
Mean±SD age of the participants was 58.4±13.1 years and females were more (f = 48; % = 50.5). The regression model from the binary regression analysis explained 73.2% (Nagelkerke R2 = 0.732) of the variance in functional independence. Good balance function was found to independently and significantly (P < 0.01) increase the likelihood of being functionally independent after stroke (Odds ratio = 1.33; 95% CI = 1.11 to 1.58).
The goal of attaining functional independence after stroke may depend to a significant extent on good balance function irrespective of the stroke survivor's age, sex and post-stroke duration.
中风后功能独立性常受到损害，恢复其功能是中风康复的目标之一。
本研究评估平衡对中风后功能独立性的影响。
尼日利亚两家医疗机构中95名正在接受物理康复治疗的中风患者参与了本研究。分别用伯格平衡量表和巴氏指数评估平衡和功能独立性。进行二元逻辑回归分析，以检验在控制参与者年龄、性别、偏瘫侧和中风后持续时间的情况下，平衡对功能独立性的独立影响。
参与者的平均年龄±标准差为58.4±13.1岁，女性更多（f = 48；% = 50.5）。二元回归分析的回归模型解释了功能独立性方差的73.2%（Nagelkerke R2 = 0.732）。发现良好的平衡功能能独立且显著地（P < 0.01）增加中风后功能独立的可能性（比值比 = 1.33；95%置信区间 = 1.11至1.58）。
中风后实现功能独立的目标可能在很大程度上取决于良好的平衡功能，而与中风幸存者的年龄、性别和中风后持续时间无关。
