Revitalizing hand function after a stroke through mind-controlled motion based on brain waves

Buzz

Recovering functionality for those fortunate enough to survive a stroke is a prolonged and challenging journey. To lend a helping hand in this recovery process, especially for the arm, Neurolutions, headquartered in the United States, has unveiled a system named IpsiHand. It aims to facilitate the smooth progress of functional recovery.

The IpsiHand system utilizes the unaffected part of the brain to assist a power-assisted hand system attached to the affected hand. This system enables grasping and opening, similar to how we hold and squeeze a ball during therapeutic interventions. Patients wear an electroencephalogram (EEG) device to detect relevant brain waves, which are then directly transmitted to the power-assisted hand device attached to their arm. The communication speed between these two devices is pushed to the highest possible level, so that when patients wish to move their hand through thought, the hand device promptly aids in the movement of their arm.Some images of the device, looks very futuristic

They conducted tests both in clinics and at home for 40 patients aged 18 and above, individuals who have suffered a stroke and are undergoing functional recovery treatment with a trial period of 12 weeks. Results indicate that the communication between EEG and the power-assisted hand device significantly improved the outcomes of functional recovery therapy, aiding patients in muscle recovery, maintenance, and expanding the range of hand movements. Only a small number experienced fatigue or irritation from prolonged device usage due to sensitive skin. The FDA has officially approved the inclusion of IpsiHand in the list of de novo devices used in rehabilitation facilities in the United States.
