Scientists creating wearable technology to aid stroke recovery

London: Researchers at the University of Southampton are creating a wearable technology that will assist people recover after stroke.

A team of researchers at the University of Southampton, England, will create a wireless sleeve to provide information about muscle movement and strength while patients practice every-day tasks at home, a university statement said on Monday.

Led by professor Jane Burridge, the two-year project has been funded with a grant of nearly 1 million pounds from the National Institute for Health Research (NIHR) through its Invention for Innovation (i4i) programme.

“Stroke rehabilitation is increasingly home-based, as patients are often discharged from hospital after only a few days. This policy encourages independence and avoids problems associated with prolonged hospital stays,” Jane Burridge, professor of restorative neuroscience at Southampton, was quoted as saying.

“However, some patients struggle to carry out the exercises and they may question whether what they are doing is correct,” Burridge added.

The wearable technology will be the first to incorporate mechanomyography (MMG) microphone-like sensors that detect the vibration of a muscle when it contracts, and inertial measurement units (IMU), comprising tri-axial accelerometers, gyroscopes and magnetometers that detect movement.

Data from the two types of sensors will be put together and then data that is not needed, for example outside noise, will then be removed from the muscle signal.

The feedback to patients will be presented on a user-friendly computer interface as an accurate representation of their movement, showing them how much they have improved.

“We hope that our sleeve will help stroke patients regain the use of their arm and hand, reduce time spent with therapists and allow them to have the recommended 45 minutes daily therapy more flexibly,” Burridge said.

Even though Karnataka recorded the lowest number of Covid deaths in April since the virus struck first in 2020, the state is recording a rise in the positivity rate (1.50 per cent). Five people died from the Covid infections in April as per the statistics released by the state health department. In March, the positivity rate stood around 0.53 per cent. In the first week of April it came down to 0.38 per cent, second week registered 0.56 per cent, third week it rose to 0.79 per cent and by end of April the Covid positivity rate touched 1.19 per cent.

on an average 500 persons used to succumb everyday in the peak of Covid infection, as per the data. Health experts said that the mutated Coronavirus is losing its fierce characteristics as vaccination, better treatment facilities and awareness among the people have contributed to the lesser number of Covid deaths.

During the 4th and 6th of April two deaths were reported in Bengaluru, one in Gadag district on April 8, two deaths were reported from Belagavi and Vijayapura on April 30. The first Covid case was reported in the state in March 2020 and three Covid deaths were recorded in the month. In the following month 21 people became victims to the deadly virus, and May 2020 recorded 22 deaths. The death toll recorded everyday after May crossed three digits. However, the third wave, which started in January 2
