A Comparison of Robotic Walking Therapy and Conventional Walking Therapy in Individuals With Upper Versus Lower Motor Neuron Lesions: A Randomized Controlled Trial

Published:January 06, 2014DOI:https://doi.org/10.1016/j.apmr.2013.12.017

      Abstract

      Objective

      To compare a walking reeducation program with robotic locomotor training plus overground therapy (LKOGT) to conventional overground training (OGT) in individuals with incomplete upper motor neuron (UMN) or lower motor neuron (LMN) injuries having either traumatic or nontraumatic nonprogressive etiology.

      Design

      Randomized open controlled trial with blind evaluation by an independent observer.

      Setting

      An inpatient spinal cord injury rehabilitation center.

      Participants

      A total of 88 adults within 6 months of spinal cord injury onset (group A, 44 with UMN injury, and group B, 44 with LMN injury) were graded on the American Spinal Injury Association Impairment Scale as C or D. Each of these groups was then randomly allocated to conditions 1 or 2.

      Interventions

      Condition 1: Subgroups A1 and B1 were treated with LKOGT for 60 minutes. Condition 2: Subgroups A2 and B2 received 60 minutes of conventional OGT 5 days per week for 8 weeks. Subjects with UMN and LMN were randomized into 2 training groups.

      Main Outcome Measures

      Ten-meter walk test and 6-minute walk test (6MWT). Walking Index for Spinal Cord Injury II, lower extremity motor score (LEMS), and the FIM-Locomotor were secondary outcome measures.

      Results

      By using the LKOGT program compared with OGT, we found significant differences in the 6MWT for groups A1 and B1. LKOGT also provided higher scores than did OGT in secondary outcomes such as the LEMS and the FIM-Locomotor.

      Conclusions

      Robotic-assisted step training yielded better results in the 6MWT and the LEMS in patients with UMN and LMN.
