A new study describes a multi-sensor tool that measures subtle changes in Multiple sclerosis patients, allowing physicians to more frequently and more quickly respond to changes in symptoms or patient condition, has published in issue of Annals of Clinical and Translational Neurology, led by researchers at University of California San Diego School of Medicine.

Multiple sclerosis (MS) is a progressive, chronic disorder in which the body's immune system attacks the central nervous system, resulting in multiple adverse effects, from numbness, fatigue and impaired speech to loss of muscle control and vision. MS affects approximately 2.5 million worldwide and there is no cure; existing treatments focus upon managing symptoms and slowing progression.

As a result, the ability to precisely assess the extent of MS-related disability and disease advancement is critical to effective treatment.

The Multi-sensor band involves wearing a small, sensor-laden band on the forearm or calf, then completing 20 finger or foot taps. Data is wirelessly downloaded to a computer in real-time. The procedure is repeated on all four limbs of the patient and takes less than five minutes.

The researchers are now preparing to publish a longitudinal analysis demonstrating the device's sensitivity to within-patient changes over short time periods. Subsequent steps include validation in a multi-site study and development of commercial-grade software to allow more expansive dissemination.
