Effectiveness of exoskeleton training on turning-while-walking and balance control in subjects with incomplete spinal cord injury: protocol for a randomised clinical trial

INTRODUCTION: Individuals with incomplete spinal cord injury (iSCI) often experience impaired balance control and turning-while-walking ability, which increase the risk of falls and limit their community mobility. While overground exoskeleton training has shown promise in improving gait and balance, evidence from randomised controlled trials (RCTs) on ambulation of individuals with iSCI remains limited. This protocol outlines a cluster RCT investigating the effectiveness of overground exoskeleton-assisted gait training compared with conventional training and usual care in improving turning-while-walking performence, balance control, and functional mobility in individuals with iSCI. METHODS AND ANALYSIS: This multicentre, cluster RCT will compare 12-week interventions across three groups: (1) overground exoskeleton training group, (2) conventional training group and (3) usual care group. Participants with ambulatory iSCI will be recruited from three centres in Hong Kong SAR and mainland China. Primary outcomes include turning duration and number of steps during a 2-m turning-while-walking test. Secondary outcomes include static and dynamic balance, sensorimotor integration, gait performance, muscle strength, spasticity, quality of life, self-efficacy and fall incidence. Assessments will be conducted at baseline, mid-intervention, postintervention and at the 1-month follow-up. ETHICS AND DISSEMINATION: This study has received approval from the Research Ethics Committees of Hong Kong Metropolitan University, the Affiliated BenQ Hospital of Nanjing Medical University, and Changzhou Sunshine Rehabilitation Hospital. Written informed consent will be obtained from all participants before enrolment. Study findings will be shared through peer-reviewed publications, conference presentations and summaries available to participants upon request. TRIAL REGISTRATION NUMBER: NCT06971510.
