Training a person with paralysis to ambulate using a powered exoskeleton may present challenges. The goals are to present the candidate selection criteria and the training procedures for exoskeletal-assisted walking and other mobility skills that can be progressed as the participant's skill level improves.

Source: Laboratory of Jonathan Flombaum—Johns Hopkins University Colloquially, the terms learning and memory encompass a broad range of behaviors and mental systems, everything from learning to tie a shoe to mastering calculus (and a lot in between). Experimental psychologists have divided up learning mechanisms into groups that seem to have different properties, and that seem to rely on different brain systems. A major division is between declarative and non-declarative memory, roughly, the...

The Rubber Hand Illusion

Source: Laboratory of Jonathan Flombaum—Johns Hopkins University Reaching for objects, walking without hitting obstacles, landing on a chair as you sit (instead of falling to the floor), these and all our physical actions depend on an ability to perceive our own bodies in space, to know where our limbs are relative to one another and relative to the rest of the world. One way that the human brain encodes this information is called proprioception, the brain relies on its own control and feedback...

We developed a real-time mirror robot system for functional recovery of hemiplegic arms using automatic control technology, conducted a clinical study on healthy subjects, and determined tasks through feedback from rehabilitation doctors. This simple mirror robot can be applied effectively to occupational therapy in stroke patients with a hemiplegic arm.
FAQs
Sensors provide the control signal by detecting voluntary movement from the user or commands selected by a therapist. The system then directs motors to guide the impaired fingers or hand through a corresponding movement. This arrangement links the patient’s attempted action with assisted mechanical output, allowing therapy to be adjusted around the person’s available movement and effort.
The approach combines seeing a mirrored movement with feeling the hand being guided through that movement. Visual feedback supplies information about the apparent bilateral action, while proprioceptive feedback comes from the assisted position and motion of the limb. Presenting these signals together gives clinicians a way to study how sensory input and assisted practice may influence neuroplasticity after neurological injury.
Controlled force and range of motion help determine how much assistance the impaired hand receives and how far it is guided during practice. These parameters create a structured setting for repetitive movement while accommodating the patient’s current ability. Their use also supports individualized therapy and provides conditions in which changes in motor recovery can be assessed more consistently.
A session can begin with the patient attempting or producing a voluntary movement, or with a therapist selecting the command to be practiced. Sensors detect the relevant input, and the device guides the impaired hand through the corresponding motion using defined force and range-of-motion conditions. Repeated bilateral practice then supplies a consistent platform for structured rehabilitation.
The system can support assessment of motor recovery while therapy is delivered. Clinicians may use its structured, assisted movements to individualize practice around the patient’s performance and ability to initiate motion. Researchers can also use the platform to examine how repetitive bilateral movement, sensory feedback, and mechanical assistance relate to neuroplasticity following neurological injury.
This approach is relevant when neurological injury leaves one hand impaired or makes movement difficult to initiate. After stroke, for example, coordinated practice can provide repetitive bilateral movements while reducing the effort needed to begin the action. Its medical value includes both rehabilitation and investigation of recovery, rather than serving only as a mechanical aid for movement.
