Previous studies have demonstrated that supervised strength training (ST) or walking training (WT) improve walking capacity in patients with claudication. However, it remains unknown whether these improvements would be sustained over a subsequent unsupervised period. This article reports the findings of a study to analyze whether the improvements in walking capacity, achieved with a supervised ST or WT, would be sustained over a subsequent unsupervised therapy period in patients with claudication. Patients were initially randomized to supervised exercise consisting of ST (n = 15) or WT (n = 15) for 12 weeks. After this period, 12 patients in each group consented to be followed for an additional 12 weeks of unsupervised therapy. Initial claudication distance (ICD) and total walking distance (TWD) were measured at baseline, after the supervised period (Week 12) and after the unsupervised period (Week 24). In comparison with baseline values, both groups similarly increased ICD and TWD at Week 12. From Week 12 to Week 24, both groups similarly decreased ICD (ST: -55 ± 110 m and WT: -82 ± 142 m, P =.04) and TWD (ST: -68 ± 186 m and WT: -128 ± 112 m, P < .01). However, in both groups, ICD (ST: +126 ± 149 m and WT: +50 ± 167 m, P = .01) and TWD (ST: +104 ± 162 m and WT: +45 ± 139 m, P =.01) at Week 24 remained greater than baseline values. The conclusion is that supervised ST or WT followed by an unsupervised therapy period similarly decreased walking capacity in patients with claudication. However, after the unsupervised period, walking capacity remained at a higher level than before the onset of the supervised exercise-training period.
先前的研究表明，有监督的力量训练（ST）或步行训练（WT）可改善间歇性跛行患者的步行能力。然而，这些改善在随后的无监督阶段是否会持续尚不清楚。本文报告了一项研究的结果，该研究旨在分析在间歇性跛行患者中，通过有监督的ST或WT所实现的步行能力改善在随后的无监督治疗阶段是否会持续。患者最初被随机分配到由ST（n = 15）或WT（n = 15）组成的有监督运动组，为期12周。在此期间之后，每组12名患者同意在无监督治疗下再随访12周。在基线、有监督阶段结束时（第12周）和无监督阶段结束时（第24周）测量初始跛行距离（ICD）和总步行距离（TWD）。与基线值相比，两组在第12周时ICD和TWD均有类似增加。从第12周到第24周，两组ICD（ST：-55±110米，WT：-82±142米，P = 0.04）和TWD（ST：-68±186米，WT：-128±112米，P < 0.01）均有类似下降。然而，在两组中，第24周时的ICD（ST：+126±149米，WT：+50±167米，P = 0.01）和TWD（ST：+104±162米，WT：+45±139米，P = 0.01）仍高于基线值。结论是，有监督的ST或WT后接无监督治疗阶段，间歇性跛行患者的步行能力同样下降。然而，在无监督阶段之后，步行能力仍维持在高于有监督运动训练阶段开始前的水平。
