Abstract

Objectives: Gait disturbances increase mortality rates in lower extremity artery disease. Changes in gait biomechanics after endovascular therapy for intermittent claudication associated with lower extremity artery disease remain unknown. This prospective study investigated the effect of endovascular therapy on gait biomechanics in intermittent claudication.

Methods: We recruited 10 patients (14 affected limbs) with intermittent claudication caused by isolated aortoiliac artery lesions who underwent endovascular therapy, and 10 healthy controls. Using 3-dimensional motion analysis, we measured biomechanical gait parameters preoperatively and over 6 months postoperatively, comparing them with those of healthy controls.

Results: One month after endovascular therapy, parameters improved significantly compared with preoperative values: step length (preoperative median 52.47 [interquartile range 47.11, 60.33]–postoperative 58.53 [54.63, 64.54] cm; P < 0.0037), walking speed (90.17 [73.98, 108.9]–103.49 [97.66, 117.94] cm/s; P = 0.0022), hip flexor moment (−0.75 [−1.04, −0.51] to −0.94 [−1.07, −0.74] Nm/kg; P = 0.04), and pull-off power generated by hip flexor muscles (H3, 0.68 [0.38, 1]–0.86 [0.72, 1.1] W/kg; P = 0.018). Preoperative joint power declined significantly compared to control parameters. However, 6 months postoperatively, no significant differences were observed.

Conclusions: Endovascular therapy for isolated aortoiliac artery lesions improved biomechanical gait parameters in patients with intermittent claudication.
