Study Overview
Brief Summary
Multiple Sclerosis (MS) is a chronic immune-mediated inflammatory disease with a broad diversity of symptoms and fluctuating progression patterns. Clinical assessments are challenging and are continually reviewed and enhanced. Optimal multiple sclerosis care depends on early detection of disease progression. The Digital self-Assessment for Multiple sclerosis (DAM) mobile program was developed by Ad Scientiam in order to create a robust and clinically validated remote monitoring platform for MS patients and clinicians. The correlation between DAM version 0 (the first iteration of DAMS) and Multiple Sclerosis Functional Composite (MSFC) has been clinically evaluated in a preliminary study in 30 subjects. DAM version 0 and MFSC global scores were correlated. However, the cognition test had a poor reproducibility and clinicians expressed the wish to measure a walking range rather than a walking speed. Even though vision is the main sense impacting all other tests, particularly when interacting with a mobile, visual tests are rarely performed in real life. A new version of DAM version 0, DAMS, was therefore developed with the addition of the Sloan Low Contrast Letter Acuity Test (SLCLAT), the replacement of the walking speed test with a walking distance test and the Paced Auditory Serial Addition Test (PASAT) by a new version of the cognitive test which resembles the Symbol Digit Modalities Test (SDMT).
The hypothesis is that systematic and prospective multi-dimensional data collection of MS disabilities through the DAMS mobile application will refine the quality and accuracy of both clinicians and patients' knowledge of the disease progression and will ultimately improve the current care of patients.
To test this assumption, the statistician will analyze:
- The global diagnostic performance of DAMS with (DAMS 4 tests) and without (DAMS 3 tests) the low contrast vision test versus standard MS scales
- The test-retest reliability of DAMS' scores at a 15 day interval

Arms & Interventions
Patients with Multiple Sclerosis
Patients will perform one or two visits at 15 days interval. Patients will be randomly assigned to either traditional/digital group (Group A) or digital/traditional group (Group B), followed by a crossover to the other group at day 15 for patients who will do two visits.
Intervention: Digital Assessment on mobile (Other)
Healthy volunteer
Healthy volunteers will only perform one visit. Healthy volunteers will be randomly assigned to either traditional/digital group (Group A) or digital/traditional group (Group B).
Intervention: Digital Assessment on mobile (Other)
