IIT Ropar Develops Patented, Low-Cost Knee Rehab Device

The Indian Institute of Technology (IIT) Ropar has made a significant breakthrough in post-surgical knee rehabilitation with the development of a patented, fully mechanical Continuous Passive Motion (CPM) machine (Patent No. 553407). Unlike traditional motorized CPM devices, which are costly and rely on electricity, this innovative solution uses a piston and pulley system that stores air as the user pulls a handle, providing smooth, controlled motion for knee recovery. Its simple, effective design eliminates the need for electricity, batteries, or motors, making it both lightweight and portable, offering an affordable and accessible alternative for rehabilitation.

Low-Cost Knee Rehab Device for Post-Surgical Care

The mechanical CPM machine presents an affordable alternative to expensive electric devices, which are often inaccessible, particularly in rural areas with unreliable electricity. By eliminating the need for power, it makes continuous passive motion therapy viable in off-grid locations. Its portability also enables patients to use it at home, reducing the need for extended hospital stays and frequent rehabilitation visits.

Continuous passive motion therapy is crucial for patients recovering from knee surgery, enhancing joint mobility, reducing stiffness, and accelerating recovery. This new mechanical device provides a cost-effective, eco-friendly alternative, offering a promising solution for affordable knee rehabilitation. Its development represents a major step toward improving healthcare access, especially in resource-limited regions. The team’s innovation is set to transform knee rehabilitation practices, making a lasting impact both in India and globally.

“This device has the potential to revolutionize knee rehabilitation in India, where access to advanced medical technology can be limited, particularly in rural areas,” said Dr. Abhishek Tiwari, the lead researcher, along with his team comprising Suraj Bhan Mundotiya and Dr. Samir C. Roy. “It’s designed to be a low-cost, sustainable solution that not only aids in recovery but also helps reduce the environmental impact associated with motorized devices”, he added.
