The main objective of this study is to determine whether a small, wearable multisensor device could discriminate between relapsing versus progressive multiple sclerosis. This would also include capturing limp progression over a short interval, using finger and foot tap data. Patients with MS is put on a regular follow-up and routine check visits every 6 months. Now the procedure goes as at each visit the patient performed finger and foot taps wearing the MYO – band, that included accelerometer , gyroscope and electromyogram sensors. The change in signal waveform features that happened over time were the resulting metrics within a patient’s limb progression. A total of 53 relapsing were done on patients in 15 progressive multiple sclerosis (MS) – (72% female, baseline mean age 48 years, median disease duration 11 years, median EDSS 2.5, median 10 months follow-up). The MS subtype is important for clinical management and the trials. The most commonly studied sensor in MS is the use of an accelerometer to measure step count which is used for physical activities, although step count accuracy may be poor and extremely precise function is not captured. The Gyroscope sensors are used to assess balance where as other sensors have not been as much in par with MS. Hence the study concluded that Biosensor vital sign detects multiple sclerosis progression.
