Efficacy of Supervised Exercise Therapy for Intermittent Claudication in a Case With Buerger's Disease.

Herein, we report a case of intermittent claudication (IC) caused by Buerger's disease (thromboangiitis obliterans {TAO}), which we treated using supervised exercise therapy (SET). The patient was a 58-year-old male with a history of smoking who presented with IC and resting pain in the right lower extremity, which had led to necrosis of the right first toe eight years prior to presentation. The non-healing right first toe was amputated and the patient underwent angiogenesis therapy in the right lower extremity. Despite continued strict smoking cessation and antiplatelet medication, the patient presented with IC of the left lower extremity eight years after the previous symptoms. Therefore, the patient underwent SET once a week (40 min per session) for five months, resulting in a total of 21 sessions. Consequently, the patient's walking ability and quality of life (QoL) significantly improved. These results suggest that SET is an effective treatment for TAO-induced IC. However, further studies are required to demonstrate its efficacy.
