Effects of Robot-Assisted Gait Training in Patients with Burn Injury on Lower Extremity: A Single-Blind, Randomized Controlled Trial.

研究概要

Forty patients with lower extremity burns undergoing split-thickness skin grafting were randomized to receive robotic assisted gait training plus conventional rehabilitation or conventional rehabilitation only for 12 weeks. The primary outcome of interest was range of motion in the hip, knee, and ankle joint. Additional outcomes of interest included functional ambulatory category (FAC) functional recovery scores, 6 minute walk test results, pain during gait movement on a Visual Analog Scale (VAS), and isometric muscle strength of the hip extensors, hip flexors, knee extensors, knee flexors, ankle dorsiflexors, and ankle plantarflexors. Outcomes were assessed before and after 12 weeks of treatment. Both groups improved significantly from baseline in VAS pain scores, FAC scores and 6 minute walk test results; however, no statistically significant differences in the improvement from baseline of those outcomes were observed between the two groups. The changes from baseline in knee flexion isometric strength in the left leg, knee extension isometric strength in the left leg, ankle dorsiflexion isometric strength in the left leg, and ankle plantar flexion isometric strength in the left leg were statistically significantly in favour of the robotic training group. No significant differences in the improvement from baseline in all range of motion outcomes were observed between the two treatment arms.
