Clinical Trial 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.

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.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Correlation with disability	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.	One time point per patient (inclusion)
Secondary	Correlation with neurological function	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	One time point per patient (inclusion)
Secondary	Correlation with gait speed	Timed 25-Foot Walk (T25FW). T25FW measures the time needed to complete a 25-foot walk. Two trials are averaged	One time point per patient (inclusion)
Secondary	Correlation with lateralization	Lower limb lateralization (right vs left)	One time point per patient (inclusion)
Secondary	Correlation with disability location	Upper, lower limb, trunk MS symptoms location	One time point per patient (inclusion)
Secondary	Correlation with MS symptoms severity	MS symptoms severity quote as none, mild moderate severe	One time point per patient (inclusion)
Secondary	Reliability of sensor measures	Gait parameters record during a 25-foot walk repeated twice at 5 min apart.	At the inclusion
Secondary	Developement of dedicated algorithm to improve signal processing from IMU.	Number of detected gait cycles during a foot walk.	Day 1
