Community living individuals with lower limb amputation have low balance confidence but the level of balance confidence in the first six months after discharge from prosthetic rehabilitation is not known.
To determine if balance confidence levels differ after discharge from prosthetic rehabilitation and to determine if balance confidence at discharge predicts social activity at three months post-discharge while controlling for important covariates such as walking ability.
Prospective study.
Subjects (n = 65) experiencing their first unilateral transfemoral or transtibial amputation were recruited and followed-up one and three months post-discharge. Measures of balance confidence (Activities-specific Balance Confidence Scale) and walking ability (L Test) collected at discharge were used to predict social activity (Frenchay Activities Index) at follow-up.
Despite a 14-second mean improvement in walking ability the mean balance confidence scores did not change significantly between discharge (71.2/100) and at three-month follow-up (69.4/100). Confidence scores and basic walking ability at discharge were the two strongest predictors of three-month social activity. Multiple regression modelling indicated that balance confidence and walking ability explained 64% of the variance (standardized beta = 0.34 and -0.37 respectively) in social activity (adjusted R(2) = 39%).
Balance confidence after discharge from prosthetic rehabilitation for lower limb amputation is low and scores do not improve over the first three months post-discharge despite improvements in walking ability. Discharge balance scores confidence independently predicts three-month social activity scores.
社区中下肢截肢的个体平衡信心较低，但假肢康复出院后头六个月的平衡信心水平尚不清楚。
确定假肢康复出院后平衡信心水平是否存在差异，并确定出院时的平衡信心是否能在控制行走能力等重要协变量的情况下预测出院后三个月的社交活动。
前瞻性研究。
招募首次经历单侧股骨或胫骨截肢的受试者（n = 65），并在出院后1个月和3个月进行随访。出院时收集的平衡信心（特定活动平衡信心量表）和行走能力（L测试）测量值用于预测随访时的社交活动（法国ay活动指数）。
尽管行走能力平均提高了14秒，但出院时（71.2/100）和三个月随访时（69.4/100）的平均平衡信心得分没有显著变化。出院时的信心得分和基本行走能力是三个月社交活动的两个最强预测因素。多元回归模型表明，平衡信心和行走能力解释了社交活动中64%的方差（标准化β分别为0.34和-0.37）（调整后R(2)=39%）。
下肢截肢患者假肢康复出院后的平衡信心较低，尽管行走能力有所改善，但出院后前三个月的得分并未提高。出院时的平衡信心得分可独立预测三个月后的社交活动得分。
