Neurolutions IpsiHand Device

"The muscles in the body are controlled by our brain’s motor cortex. It has been classically understood that one side of the brain controls the opposite side of body, thus the motor cortex on the left side of the brain controls the right hand. This idea of opposite sided control is referred to as contralateral control. When an area of brain, such as the motor cortex, is injured from a stroke due to lack of blood supply or bleeding within the brain, it may leave the person paralyzed on the opposite side of their body. Research has shown that the classic dogma that one side of the brain controls the opposite side of the body is not completely correct. There are still portions of the brain involved with same sided limb movements or ipsilateral motor movements. These are preserved in the setting of a stroke. We can find specific brain signals associated with the same sided hand and limb movements. These can be detected noninvasively with the EEG headset where electrodes are placed on the scalp. The signals, or intention to move their hand, are decoded by a brain computer interface to a robotic exoskeleton known as the IpsiHand, which can open and close the hand for the patient even though they cannot physically do it on their own. With ongoing usage, this leads to rewiring of the brain that creates new connections between the uninjured brain and the hand thus restoring the brain’s ability to control the paralyzed hand. "
