ExoAtlet II For SCI Patients

Not Applicable

Completed

• Conditions: Spinal Cord Injuries; Paraplegia
• Interventions: Device: Gait training using ExoAtlet exoskeleton

• Registration Number: NCT04215081
• Lead Sponsor: ExoAtlet

Brief Summary

This study will evaluate the ExoAtlet II exoskeleton for safety and effectiveness of providing persons with a spinal cord injury (SCI) who are non-ambulatory or have limited ambulatory function, to stand up and ambulate under a variety of conditions.

Detailed Description

The study will introduce the ExoAtlet II exoskeleton to SCI patients with lower extremity paralysis (partial or complete) and provide rehabilitative standing and walking intervention. The study will be conducted with a trained clinician that will fit each patient into the adjustable exoskeleton system and provide customized programming to meet each user's specific needs. The training program will be initiated based upon each patient's comfort in the exoskeleton and ability to stand with assistance. Each patient will be closely monitored to assess ongoing health as well as their individual standing and walking ability. All exoskeleton sessions will be performed with a trained medical professional controlling the exoskeleton. Patient safety is the primary concern and all adverse events will be documented and addressed. This study will evaluate the ExoAtlet 2.0 exoskeleton for safety and effectiveness of providing persons with a spinal cord injury (SCI) who are non-ambulatory or have limited ambulatory function, the ability to stand up and walk in a clinical facility.

12. Blood pressure and heart rate within established guidelines for locomotive training: At rest; Systolic 150 or less Diastolic 90 or less and Heart rate 100 or less Exercise; Systolic 180 or less, Diastolic 105 or less and Heart Rate 145 or less

Exclusion Criteria

1. Spinal cord injury level higher than T4 or C7 ASIA D

3. Significant spasticity (Modified Ashworth Scale score of 3 or above)
4. Trunk or lower extremity pressure ulcer
5. Open Wounds/tissue hypersensitivity
6. Unstable spine, un-healed limbs, or fractures
7. Severe sensitivity to touch
8. Presence of bone in soft tissue where bone normally does not exist (heterotopic ossification), limiting range of motion in the hip or knee joints
9. Joint instability, dislocation, moderate to severe hip dysplasia
10. Significant scoliosis (>40 degrees)
11. Hardware, implant, or any external device impeding with safe fitting or use of ExoAtlet 2.0
12. Femoral or tibial rotation deformity (>15 degrees)
13. Significant flexion contractures limited to 35º at the hip and 20º at the knee
14. Uncontrolled seizures, musculoskeletal injury, fracture or lower-limb surgery in past year.
15. Known history of pulmonary disease limiting exercise tolerance or history of cardiac disease
16. Psychopathology, or other condition that the physician or investigator, in his or her clinical judgment, considers to be exclusionary to safely use an exoskeleton.
17. Severe concurrent medical diseases, illness, systemic or peripheral infection
18. Dizziness or headache with standing

Arm && Interventions

Group	Intervention	Description
ExoAtlet II Safety and Efficacy	Gait training using ExoAtlet exoskeleton	20 participants with paraplegia from SCI will participate in gait training using ExoAtlet II powered exoskeleton.

Primary Outcome Measures

Name	Time	Method
Number of adverse events	0-8 weeks	Document and track any adverse events, both minor and major, during exoskeleton sessions.
Skin integrity	0-8 weeks	A visual inspection of the participant's skin, at all areas of contact with the exoskeleton, will be conducted at the beginning and end of each session.

Secondary Outcome Measures

Name	Time	Method
10 Meter Walk Test	1 Day	Assesses walking speed, in the exoskeleton, in meters per second over a distance of 10 meters
Transfer in and out	2 Days	Percentage of patients able to successfully transfer in and out of the exoskeleton with or without assistance
6 Minute Walk Test	1 Day	Record the distance covered during a 6 minute walk test utilizing the exoskeleton, to evaluate users endurance
