Brief summary
Gait alteration is frequent in MS and limitation in walking ability is a major concern in MS patients. The development of wearable device offers the opportunity to collect data during daily activity including walking.
Detailed description
Umanit and LMJ (Nantes university) has developed a device call eMSgait to assess walking ability in MS patients individuals (eg MS patients). This device consists in a commercialized IMU sensor (MetaMotionR Sensor, Mbientilab) worn at the right hip, a smartphone app and dedicated algorithm/mathematical model to extract raw sensor data and calculate individual gait pattern (IGP). This IGP consists of a curve, based on quaternion and representing the rotation recorded by the IMU during an average gait cycle. Pursue first pilot work assessing information from IGP on gait alteration in MS.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Correlation with disability | One time point per patient (inclusion) | Correlation of gait measures (mean amplitude of walking cycles (m), mean duration of walking cycles (s), Stance swing phase ratio) obtained during a walk of 25 feet with Expanded Disability Status Scale (EDSS). EDSS is an ordinal scale measuring disability and ranging from 0 (normal examination) to 10 (death due to MS) in a 0,5-point increments from score 1. |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Correlation with gait speed | One time point per patient (inclusion) | Timed 25-Foot Walk (T25FW). T25FW measures the time needed to complete a 25-foot walk. Two trials are averaged |
| Correlation with lateralization | One time point per patient (inclusion) | Lower limb lateralization (right vs left) |
| Correlation with disability location | One time point per patient (inclusion) | Upper, lower limb, trunk MS symptoms location |
| Correlation with neurological function | One time point per patient (inclusion) | Pyramidal, cerebellar and sensory functions are assessed with Kurtzke functional system scores which are based on neurological examination. Scores of the Pyramidal and sensory systems range from 0 (normal) to 6 . Cerebellar system scores range from 0 (normal) to 6. Cerebellar system scores range from 0 (normal) to 5 |
| Reliability of sensor measures | At the inclusion | Gait parameters record during a 25-foot walk repeated twice at 5 min apart. |
| Developement of dedicated algorithm to improve signal processing from IMU. | Day 1 | Number of detected gait cycles during a foot walk. |
| Correlation with MS symptoms severity | One time point per patient (inclusion) | MS symptoms severity quote as none, mild moderate severe |
