Answer: IIT Ropar
Notes: IIT Ropar researchers developed a patented mechanical passive motion machine for knee rehabilitation (Patent No. 553407). Unlike motorized CPM machines, this device is entirely mechanical, using a piston and pulley system, needing no electricity or batteries. The lightweight, portable machine allows for smooth, controlled knee motion, aiding recovery post-surgery. It provides an affordable alternative to costly electric machines, beneficial in rural or off-grid areas. The device can be used at home, reducing hospital visits and promoting faster recovery.
