Problem
Addressed

Stroke is a leading cause of disability worldwide, with
rising cases in India due to increased life expectancy. It
often impairs motor functions, affecting quality of life.
A BCI-controlled robotic hand and arm exoskeleton
can aid post-stroke rehabilitation by combining
mental imagery (Ml) with physical practice (PP). This
integration stimulates brain plasticity and enhances
motor recovery. The BCI detects the patient’s intent
and activates the exoskeleton, reducing the need for
constant physiotherapist supervision and encouraging
functional independence.
