About

Roshan Rai is a pioneering researcher at the intersection of rehabilitation engineering and accessible healthcare technology. His work focuses on developing affordable, robotic-assisted therapies for stroke survivors and individuals with motor-cognitive impairments, particularly in low-resource settings. Rai’s major contributions include the creation of the Haptic TheraDrive and the Rehab CARES system—a compact robot gym designed to democratize post-stroke rehabilitation. His most cited paper, “Affordable stroke therapy in high-, low- and middle-income countries” (43 citations), outlines this evolution from a single-device approach to a comprehensive, low-cost rehabilitation platform. Beyond stroke care, Rai has advanced assistive robotics for aging populations, as shown in his study on older adults’ interaction with mobile assistive robots (24 citations), and developed sensorized toys to quantify infant motor development (16 citations). His work also explores using upper-limb kinematics to disentangle cognitive deficits from motor impairments in patients with both HIV and stroke. By combining high-force haptic feedback with off-the-shelf gaming hardware, Rai’s innovations are making effective rehabilitation accessible where expert therapists and expensive equipment are scarce—a transformative achievement for global health equity.
