Wearable biosensors to monitor disability in multiple sclerosis.

PURPOSE OF REVIEW: Biosensors capable of measuring physiologic and kinetic parameters associated with disability are being applied to the study of people with multiple sclerosis (MS). We review the use of biosensors in people with MS with an emphasis on measuring/monitoring disability and understanding knowledge gaps between biosensor data and clinical care. RECENT FINDINGS: Accelerometers are available to the public and may be able to help the clinician understand a patient's degree of disability. Further studies with wearable biosensors capable of measuring other physiologic features, such as vital signs, are needed and are likely to contribute to our understanding of MS. SUMMARY: Wearable biosensors can improve our understanding of disability, response to treatment, and natural history of MS.
