Methods and systems for controlling body parts and devices using ipsilateral motor cortex and motor related cortex

a technology of ipsilateral motor cortex and motor related cortex, applied in the field of neurosurgical treatment, can solve the problems of inability to control the hand function of subjects with hemispheric stroke, the financial cost of lifetime care for u.s. subjects is typically prohibitive, and the opposite side of the body is typically left paralyzed or weak

AI Technical Summary

Benefits of technology

[0007]The foregoing problems are solved and a technical advance is achieved by methods, systems and articles of manufacture consistent with the present invention, which provide neuroprosthetic controls of both sides of the body by using a single brain hemisphere.

Problems solved by technology

As such, when an individual has a stroke on one side of the brain, the opposite side of the body is typically left paralyzed or weak.
Financial cost of lifetime care for U.S. subjects suffering from hemispheric stroke is typically prohibitive.
Hemiparesis is one of the most common reasons for their disability, and it is often hand function that is impaired.
The conventional techniques used in these studies, however, possess limitations of either spatial or temporal resolution, prohibiting a more definitive understanding of cortical processing of ipsilateral hand movements.

Embodiment Construction

[0032]Reference will now be made in detail to an implementation consistent with the present invention as illustrated in the accompanying drawings. Wherever possible, the same reference numbers will be used throughout the drawings and the following description to refer to the same or like parts. As would be understood to one of ordinary skill in the art, certain components or elements are not shown in the figures or specifically noted herein to avoid obscuring the invention.

[0033]Conventional brain computer interfaces (BCIs) have typically offered minimal benefit to subjects with motor impairment due to, for example, unilateral stroke because conventional platforms or systems rely on signals derived from the contralateral motor cortex, which is the same region injured by the stroke or other impairment. For a BCI to assist a hemiparetic subject, the unaffected cortex ipsilateral to the affected limb (opposite the side of the stroke) needs to be utilized. The affected limb or body part...

Abstract

A system for controlling a body part includes a number of sensing devices that sense signals from a hemisphere of a brain. A signal translating unit translates the signals into a command signal for controlling the body part, which is on a same side of the body as the hemisphere of the brain. A prosthetic device receives the command signal from the signal translating unit and manipulates the body part in response to the command signal.

Description

RELATED APPLICATION DATA[0001]This application claims the benefit of the filing date of U.S. Provisional Application No. 60 / 922,433, entitled “METHODS AND SYSTEMS FOR CONTROLLING BODY PARTS USING IPSILATERAL MOTOR CONTROL,” filed on Jun. 5, 2007, which is incorporated herein by reference to the extent permitted by law.FIELD OF THE INVENTION[0002]The present invention relates, generally, to neuroprosthetics and, more particularly, to methods and systems for controlling body parts and devices using ipsilateral motor cortex and motor related cortex.BACKGROUND OF THE INVENTION[0003]In normal brain function, one side of the brain (a hemisphere) controls the opposite side of the body. Thus, the right brain (right cerebral hemisphere) controls the left side of the body and the left brain (left cerebral hemisphere) controls the right side of the body. As such, when an individual has a stroke on one side of the brain, the opposite side of the body is typically left paralyzed or weak.[0004]Th...
