Objective

To evaluate current published literature reporting the clinical utility of digital biomarker measures for gait, voice and cognition in patients with multiple sclerosis (MS).

Background

A substantial unmet need exists for more sensitive monitoring of MS manifestations and disease trajectories, especially early in the disease process. Digital solutions are emerging that are objective and more easily deployed than traditional measures, with the potential to better represent disease manifestations through multidimensional assessments; however, the maturity of these digital technologies remains unclear.

Design/Methods MEDLINE and Embase databases were systematically searched (January 2017 to April 2023) to identify studies that reported clinical applications of digital biomarkers for gait, voice and cognition in patients with MS. Publications in English with ≥50 participants were eligible for inclusion; publications describing studies of cognition were limited to those reporting remotely deployed technologies.

Results

In total, 74 publications were identified for inclusion after second-level screening (gait, 51; voice, 6; cognition, 17). The number of publications per year increased for all digital solutions from 2017 to 2022 (gait, 5 to 13 publications; voice, 0 to 2; cognition, 0 to 6, respectively). The most commonly reported devices for gait, voice and cognition, respectively, were wearable sensors (27% of gait studies), microphones (83% of voice studies), and smartphones (94% of cognition studies). Digital biomarker results were compared with reference standards in most studies (gait, 86%; voice, 67%; cognition, 82%). Most gait (67%) and all voice studies collected data only in a clinical setting.

Conclusions The number of studies evaluating gait, voice and cognitive digital biomarkers to better phenotype and predict disease trajectories in patients with MS is increasing. Substantial opportunity to validate digital solutions in clinical practice remains, especially for those deployed remotely.
