February 21, 2018, 3:28 pm A stroke is a medical condition where due to certain reasons, inadequate blood flow to the brain results in cell death. Strokes are one of the leading cause of death and disability, not only in India but all over the world.

They affect about 15 million people worldwide and have left almost 5 million disabled. According to studies, almost 75% of stroke victims become physically disabled, and out of those, 77% suffer upper limb weakness, with muscle numbness and difficulties in carrying out daily activities.

Therefore, stroke rehabilitation plays an integral part in preventing post-stroke disabilities and helping a person return to regular life. Physiotherapy is often an essential part of rehabilitation after a stroke and helps the patient to recover muscle strength, joint movement and a range of vital capacity.

Researchers at IIT Gandhinagar have incorporated an ingenious solution—computer-based VR games—to address upper-limb movement disorder in post-stroke victims. Virtual reality or VR gives users a sense of touch when augmented with add-on instruments. Putting advances in the field of VR to use in the recovery of stroke patients, Dr Uttama Lahiri and her group have developed a technique which is a computer-based exercise platform, which is a performance-sensitive platform that can intelligently adapt itself according to the performance of patients.

This virtual gaming world is augmented with a sense of touch in which patients can feel objects in the game environment and can manipulate objects with their movements. Using this as a cornerstone, patients interacting with the simulated environment can help in practising reaching and coordination tasks. Read more from…
