Neurorehabilitation of Cognitive Deficits in Multiple Sclerosis Using an Adaptive Cognitive Exergame - Randomized, Controlled, Multi-center Clinical Trial

Approximately 2.8 million people worldwide suffer from multiple sclerosis (MS). In 40 to 70% of cases, individuals with MS experience cognitive impairments that significantly interfere with their personal lives, careers, and quality of life. Current pharmacological and neurorehabilitation treatment options do not adequately reduce cognitive deficits. The absence of standards of care in Switzerland or internationally regarding cognitive neurorehabilitation in MS highlights the need for effective interventions with lasting effects.

To address this need, we are exploring different approaches to support and improve cognitive impairments through training exercises using computerized tools. Traditionally, these exercises are in paper-and-pencil format, consisting of tests, puzzles, and memory tasks. While this approach is useful, computerized tools now allow us to offer more playful, interactive, and engaging approaches.

In this study, we are examining the effect of serious video games (a medical device) on cognitive deficits related to MS. The serious video games we are testing have already been evaluated at CHUV in individuals with MS and cognitive impairments. This recent study demonstrated the feasibility and safety of using these games in people with MS. With the current study, we aim to test these tools on a larger scale in order to better understand their effects on cognitive functions. More specifically, we seek to determine which of the two proposed interventions provides the greatest cognitive benefits.

Inclusion: Informed Consent signed by the participant,; Adults 18+ years,; Patients with a diagnosis of relapsing multiple sclerosis according to the most recent internationally recognized criteria, as evaluated by their treating physicians (Thompson et al., 2018) or secondary progressive MS (diagnosis ≤ 30 months),; Presence of cognitive complaint,; Z-Score ≤ -0.5 in the Symbol Digit Modalities Test (SDMT).

Exclusion: Clinically or radiologically confirmed MS relapses within 3 months prior to enrollment,; Change in disease modifying treatments (DMT), antidepressant or anxiolytic medication within 1 month prior to enrollment,; Major psychiatric and/or neurocognitive disorders according to the DSM-5 (APA, 2013),; High risk of falls based on a completion time of more than 15 seconds in the Four Square Step Test (FSST) (Dite \& Temple, 2002),; Assisted locomotion or falls in the past 3 months as evaluated in the enrollment interview (Hopkins Falls Grading Scale (Grade > 1)),; Incapacity to discriminate colors (Ishihara test; (Clark, 1924)),; Insufficient language knowledge to understand instructions or questionnaires,; High-risk pregnancy as evaluated by the appointed gynecologist; Z-Score ≤ -3.5 in the Symbol Digit Modalities Test (SDMT).
