Clinical Trial Summary

The purpose of this research study is to test the effect of early exoskeletal-assisted walking (EAW) training (combined into regular acute inpatient rehabilitation (AIR)) on improving functional recovery and reducing pain and inflammation. Powered exoskeletons are a technology that offer standing and walking for certain persons with spinal cord injury (SCI) who meet the using indication of the device and have been used in the chronic SCI population with positive benefits in ability to move, daily function (such as bathing and dressing), body composition (such as lean and fat tissue mass), and quality of life (QOL). Despite the potential for EAW to promote functional recovery and reduce secondary medical complications (such as urinary tract infections and pain), no reports exist on the use of exoskeletons in AIR.

Description:

People with spinal cord injury (SCI) can have an abrupt loss of upright mobility, function and physical activity. Inflammation and pain are reported to be increased, with negative impacts on quality of life. Powered exoskeletons are a technology that offer standing and walking for eligible persons with SCI and have predominantly been used in the chronic SCI population with positive benefits in mobility, function, body composition, and quality of life (QOL). Despite the potential for exoskeletal-assisted walking (EAW) to promote functional recovery and mitigate secondary medical complications, no reports exist on the use of exoskeletons in acute inpatient rehabilitation (AIR). The goal of this study is to test the effect of early EAW training (incorporated into regular AIR) on accelerating functional recovery and reducing pain and inflammation. A total of 30 people with non-progressive SCI (≥18 years; <6 months after SCI), who are clinically eligible for gait training during AIR, will be randomly assigned into one of two groups (15 participants/group, stratified evenly for traumatic and non-traumatic SCI). The intervention group will receive gait training with an Ekso powered exoskeleton, incorporated into usual 3-hour AIR (AIR with EAW group). The control group will have usual 3-hour AIR, but without using an exoskeleton (AIR only group). Motor function, functional activities, pain and inflammation will be assessed after enrollment in the study and before discharge from AIR. The intervention group is expected to have significantly better outcomes compared with the control group. The impact of successful completion of this study would increase knowledge of the effect of using EAW during acute/subacute AIR. The expected outcome of this study is that exoskeletal-assisted walking during AIR will have significantly greater effects on mitigating some of the secondary consequences of paralysis from SCI during the early phases of recovery and rehabilitation.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Change in Spinal Cord Independence Measure (SCIM) Version III Scores	Functional activities will be assessed using Spinal Cord Independence Measure (SCIM) scores evaluated by clinicians. Full Scale range from 0-100, higher score indicates more independence. Each subscale score is evaluated within the 100-point scale (self-care: 0-20; respiration and sphincter (R & S) management: 0-40; mobility: 0-40)	Baseline and before discharge from acute inpatient rehabilitation (average 2-3 weeks)
Secondary	Change in International Standards for Neurological Classification of SCI (ISNCSCI)	Motor and sensory function was assessed by a physiatrist using the International Standards 152 for Neurological Classification of Spinal Cord Injury (ISNCSCI) to determine a total motor score (TMS, ranges from 0 to 100), upper extremity motor score (UEMS, ranges from 0 to 50), lower extremity motor score (LEMS, ranges from 0 to 50), total light touch score (TLTS, ranges from 0 to 112), total pin prick score (TPPS, ranges from 0 to 112), and total sensory score (TSS, ranges from 0 to 224). Higher score indicates better function.	Baseline and before discharge from acute inpatient rehabilitation (average 2-3 weeks)
Secondary	Change in International Spinal Cord Injury Basic Pain Data Set (ISCIBPDS) 2.0	Change in International Spinal Cord Injury Basic Pain Data Set (ISCIBPDS) 2.0 contains critical questions about clinically relevant information concerning SCI-related pain during the last 7 days, including pain intensity, the influence of pain on daily activities, mood, and sleep between admission and discharge. Full scale from 0-10, higher score indicates more pain.	Baseline and at discharge from acute inpatient rehabilitation (average 2-3 weeks)
Secondary	Number of Participants With Neuropathic Pain	Number of participants with neuropathic pain as measured by the Spinal Cord Injury Pain Instrument (SCIPI).; Spinal Cord Injury Pain Instrument (SCIPI) is a tool used to classify pain after SCI using 4 questions. It can be easily used by clinicians in every clinical setting to identify the pain classifications, including neuropathic, nociceptive, neither or unknown. Full scale from 0 to 4, a score of 1 or more than 1 indicates probable neuropathic pain.	Baseline and discharge from acute inpatient rehabilitation (average 2-3 weeks)
