At-Home Gait Assessment

A Wearable Remote Data Capture Solution for Home-Based Gait Assessment in Multiple Sclerosis

The goal of this study is to validate an MS Gait Remote Capture and Analysis (MS-GRCA) system based on wearable shoe-based motion sensors for home-based and repeatable gait assessments.

This is a single-site observational longitudinal study to validate an MS Gait Remote Capture and Analysis system for home-based and repeatable gait assessments. The investigators will recruit 30 participants who will have an in-person baseline visit (informed consent, standard gait assessment, sensor-based gait assessment, self-reported questionnaires), followed by three remote visits (sensor-based gait assessment, SUS questionnaire [last remote visit only]).

Inclusion Criteria:

• Ages 18-70 years old (inclusive)
• Confirmed diagnosis of MS (any MS subtypes, Relapsing Remitting [RR], Primary Progressive [PP], or Secondary Progressive [SP])
• PDSS score from 0 to 5
• Stable and continuous access to internet at home
• Adequate home facilities (enough space, quiet and distraction free area)
• Ability to provide informed consent.

Exclusion Criteria:

• Below average estimated premorbid cognitive functioning (based on WRAT-4 reading recognition standard z-score < 85).
• Presence of severe cognitive impairment (based on SDMT age normative z-score < -3.0).
• Presence of primary neurological disorders other than MS or primary psychiatric disorder that would influence ability to complete assessments.
