Randomized Controlled Trial
A feasibility double-blind randomized placebo-controlled trial of extracorporeal shockwave therapy as a novel treatment for intermittent claudication.
Intermittent claudication is the most common symptom of peripheral arterial disease. Previous research has suggested that extracorporeal shockwave therapy (ESWT) may induce angiogenesis in treated tissue. The objective of this feasibility pilot trial was to assess the safety, tolerability, and efficacy of ESWT as a novel treatment. ⋯ ESWT is safe and well tolerated when it is applied to the calf and demonstrated significant improvements in walking distances. Current conservative management of intermittent claudication includes supervised exercise. The early results with ESWT as an alternative, noninvasive treatment option show great potential. The mechanism of action, durability of the clinical effect, and cost-effectiveness of ESWT for claudication require further investigation.
