Evaluation of the effectiveness of spinal cord stimulation in patients with critical lower limb ischemia using the WIQ questionnaire

Aim. To evaluate various parameters of walking using the Walking Impairment Questionnaire (WIQ) in patients with critical lower limb ischemia (CLLI) before and one year after spinal cord stimulation (SCS). Methods. In 46 patients with CLLI aged 64.5 (54.9-72.6) years, the following parameters were assessed before and one year after SCS using the WIQ questionnaire: pain, distance, speed, stairs, where 100% no restrictions when walking. Results. In patients with CLLI, low WIQ values were initially identified for the scales of distance, speed, and stairs, less than 10%, and about 30% for the pain scale. One year after SCS, the values of pain, distance, and speed increased to 83.3% (68.4%-100%), 39.5% (17.9%-55.2%), and 24.4% (17.3%-35.8%), respectively, with significance at p
