Muscle weakness in the lower limbs and impeded gait performance are common in persons with late effects of polio.
To assess self-reported walking ability in persons with late effects of polio and determine the relationship with objectively assessed gait performance.
One-hundred and twenty-two individuals with prior polio (65 women and 57 men, mean age 65 [SD ± 9] years) participated in the study. The main outcome measures were: Walk-12 (Swedish version) to assess self-reported walking ability, and Timed "Up & Go", Comfortable Gait Speed, Fast Gait Speed and 6-Minute Walk Tests to assess gait performance objectively.
More than 50% of the participants reported limitations (moderately or quite a bit) related to standing or walking, climbing stairs, walking speed and distance, concentration and effort, and gait quality aspects. Half of the participants reported no need to use support when walking indoors or outdoors, but 58% reported that their ability to run was extremely limited. Significant correlations (P < 0.01) were found between the Walk-12 and the four gait performance tests (rho -0.66 to 0.63).
The strength of the relationship implies that Walk-12 reflects broader dimensions than the objective gait performance tests and can be a complement when the walking ability in persons with late effects of polio is evaluated.
下肢肌肉无力和步态表现受损是脊髓灰质炎后遗症患者的常见问题。
评估脊髓灰质炎后遗症患者的自我报告步行能力，并确定其与客观评估步态表现的关系。
共有 122 名既往患有脊髓灰质炎的患者（65 名女性和 57 名男性，平均年龄 65 [SD ± 9] 岁）参与了这项研究。主要结局指标包括：Walk-12（瑞典语版）评估自我报告的步行能力，以及计时“上与下”、舒适步行速度、快速步行速度和 6 分钟步行测试评估步态表现的客观指标。
超过 50%的参与者报告在站立或行走、爬楼梯、行走速度和距离、注意力和努力以及步态质量方面存在限制（中度或相当程度）。一半的参与者报告在室内或室外行走时无需使用支撑，但 58%的参与者报告他们的跑步能力极其受限。Walk-12 与四项步态表现测试之间存在显著相关性（P < 0.01）（rho 值为 -0.66 至-0.63）。
这种关系的强度表明，Walk-12 反映了比客观步态表现测试更广泛的维度，并且可以作为评估脊髓灰质炎后遗症患者步行能力的补充。
