Abstract
Methods and/or systems for diagnosing, monitoring and/or treating persons at risk for falling and/or other pathological conditions. In an exemplary embodiment of the invention, people are diagnosed before they actually start falling. Optionally, the diagnosis includes trying out and identifying one or more fall triggers using virtual reality tools. Optionally or alternatively, treatment includes training the persons using situations and/or triggers which are determined to be relevant for that person.
Claims52
A method of assessment of impairment, comprising:
- presenting a subject with a plurality of motor and cognitive dual tasking provocations delivered by virtual reality (VR) on a display during locomotion selected to provoke at least one gait pathology associated with dual tasking, at least one of said provocations including a vertical component, wherein at least a partial virtual representation of movement of the feet of said subject viewed from the back is presented on said display at a distance from the eyes of said subject as part of a task designed to allow negotiation of said provocations by said partial virtual representation of the feet movement of said subject viewed from the back on said display, wherein said at least a partial virtual representation indicating movement of the feet of the subject gives the subject feedback as to negotiating vertical and horizontal obstacles, wherein said feedback includes presenting by said VR a vertical distance of a forefoot of the subject from the obstacle, wherein said presenting in said VR includes presenting an avatar in said VR, said avatar including at least the foot of the subject passing over the obstacle while the subject is walking;
- and wherein said display is fixed relative to a surface on which said subject walks;
- measuring one or more physiological parameters of the subject during said locomotion;
- and
- assessing a plurality of impairments based on said measuring, each of said impairments comprise one or more of cognitive and motor dual tasking associated impairments, wherein said cognitive impairments comprise one or more of executive function, attention, planning, and visual spatial processing.
Apparatus for gait based assessment of a subject, comprising:
- (a) a display;
- (b) a controller configured to:
- present at least a partial virtual representation of movement of the feet of said subject viewed from the back, at a distance from the eyes of said subject on the display and present a plurality of motor and cognitive dual tasking provocations during locomotion calculated to induce a fall or near fall on the display, at least one of said provocations including a vertical component, wherein said dual tasking provocations comprise one or more obstacles presented on said display, and wherein said at least a partial virtual representation indicates movement of the feet of the subject gives the subject feedback as to negotiating vertical and horizontal obstacles, wherein said feedback includes presenting by said VR a vertical distance of a forefoot of the subject from the obstacle, wherein said presenting in said VR includes presenting an avatar in said VR, said avatar including at least the foot of the subject passing over the obstacle while the subject is walking;
- measure one or more physiological parameters of the subject during said locomotion;
- assess a plurality of impairments based on one or more measured physiological parameters, each of said impairments comprise cognitive and motor dual tasking associated conditions, and wherein said cognitive conditions comprise one or more of executive function, attention, planning and visual spatial processing.
A method of assessment of impairment, comprising:
- presenting a subject with a plurality of motor and cognitive dual tasking provocations delivered by virtual reality (VR) environment during locomotion selected to provoke at least one gait pathology associated with dual tasking, at least one of said provocations including a vertical component, wherein at least a partial virtual representation of movement of the feet of said subject viewed from the back is presented in said VR environment as part of a task designed to allow negotiation of said provocations by said partial virtual representation of the feet movement of said subject viewed from the back, wherein said at least a partial virtual representation indicating movement of the feet of the subject gives the subject feedback as to negotiating vertical and horizontal obstacles, wherein said feedback includes presenting in said VR environment a vertical distance of a forefoot of the subject from the obstacle, wherein said presenting in said VR environment includes presenting an avatar in said VR environment, said avatar including at least the foot of the subject passing over the obstacle while the subject is walking;
- measuring one or more physiological parameters of the subject during said locomotion;
- and
- assessing a plurality of impairments based on said measuring, each of said impairments comprise one or more of cognitive and motor dual tasking associated impairments, wherein said cognitive impairments comprise one or more of executive function, attention, planning, and visual spatial processing.
