Primary outcomePrimary: Speed in the Timed 25 Feet Walk Test at Self-selected Speed (Without Exoskeleton) — 0.35 meters per second (m/s)

Summary

The purpose of this study is to investigate whether a wearable robotic exoskeleton can help people with multiple sclerosis (MS) to walk again.

Eligibility Criteria

Subjects will be enrolled if they meet the following inclusion criteria:

Age 18 years or older
Ambulatory with assistive devices (Ambulation status will be determined by the EDSS score)
With an Expanded Disability Status Scale (EDSS) score between 6 and 7.5 inclusive
Height and weight are between 160 and 188 cm (5'2'' to 6'2''), and less than 100 kg (220 lb), respectively (per exoskeleton manufacturer)
Able to follow simple 3 step commends
Able to understand the study procedure and consent form

Subjects will be excluded if they have any of the following exclusion criteria:

History of severe neurologic injuries other than MS (Spinal Cord Injury, Cerebral Palsy, Amyotrophic Lateral Sclerosis, Traumatic Brain Injury, Cerebral Vascular Accident, etc.)
Severe comorbidities:
active infections
heart, lung, or circulatory conditions
pressure ulcers
Documented severe osteoporosis affecting the hip and spine
Severe spasticity in the lower extremities (Modified Ashworth ≥ 3) or uncontrolled clonus
Unhealed limb or pelvic fractures
Skin issues that would prevent wearing the device
Range of motion restrictions that would prevent subject from achieving a normal, reciprocal gait pattern, or would restrict a subject from completing normal sit to stand or stand to sit transitions.
Upper extremity strength deficits that limit ability to balance with a front rolling walker or crutches.
Heterotopic ossification that resists functional range of motion in lower extremities
Contractures (>15 degrees at the hips or >20 degrees at the knees)
Psychiatric or cognitive comorbidities resulting in motor planning or impulsivity concerns
Colostomy
Have received any physical therapy intervention within 3 months prior to enrolment in the study
Non-English speaking
