需要进行具有挑战性的临床平衡测试来暴露下肢假肢使用者的平衡缺陷。这项研究检验了缩小波束行走是否可以克服固定宽度波束行走中的概念和实际限制。横截面。单侧下肢假肢使用者。参与者沿着一根低矮、狭窄的横梁行走 10 次。使用标准化步行距离来量化表现。应用启发式规则来确定缩小波束任务对于每个参与者来说是否“太容易”、“太难”或“适当具有挑战性”。线性回归和 Bland-Altman 图用于确定前 5 次试验的组合是否可以预测参与者稳定的平衡木行走表现。四十名单侧下肢假肢使用者参与其中。对于 98% 的参与者来说，缩小木梁行走具有一定的挑战性。在 5 项试验中，93% 的参与者表现稳定，而 62% 在所有试验中表现稳定。试验 3-5 的平均值准确地预测了稳定的性能。临床窄梁行走测试可能会对一系列下肢假肢使用者提出挑战，管理负担最小，并且不会表现出地板或天花板效应。因此，缩小平衡木行走是一种临床上可行的评估下肢假肢使用者平衡能力的方法，但在用于评估跌倒风险之前需要进行心理测试。
Challenging clinical balance tests are needed to expose balance deficits in lower-limb prosthesis users. This study examined whether narrowing beam-walking could overcome conceptual and practical limitations identified in fixed-width beam-walking. Cross-sectional. Unilateral lower-limb prosthesis users. Participants walked 10 times along a low, narrowing beam. Performance was quantified using the normalized distance walked. Heuristic rules were applied to determine whether the narrowing beam task was “too easy,” “too hard,” or “appropriately challenging” for each participant. Linear regression and Bland-Altman plots were used to determine whether combinations of the first 5 trials could predict participants’ stable beam-walking performance. Forty unilateral lower-limb prosthesis users participated. Narrowing beam-walking was appropriately challenging for 98% of participants. Performance stabilized for 93% of participants within 5 trials, while 62% were stable across all trials. The mean of trials 3–5 accurately predicted stable performance. A clinical narrowing beam-walking test is likely to challenge a range of lower-limb prosthesis users, have minimal administrative burden, and exhibit no floor or ceiling effects. Narrowing beamwalking is therefore a clinically viable method to evaluate lower-limb prosthesis users’ balance ability, but requires psychometric testing before it is used to assess fall risk.
