Keep Your Knee Moving. Speed Up Your Recovery.
The CPM-B Knee Rehabilitation Machine delivers continuous passive motion (CPM) therapy — gently moving the knee through controlled flexion and extension cycles to restore joint mobility after surgery, injury or stroke.
For broader continuous passive motion coverage, see the ZB-X1002E CPM Knee Machine, the Upper-Limb CPM 2-in-1 and the YTK-E Upper-Limb CPM in our CPM equipment range.
The Challenge
After knee surgery, fracture, stroke or arthritis, the joint stiffens when it doesn’t move. Stiffness, swelling, limited range of motion and fear of pain slow down recovery — and patients can’t always access enough manual physiotherapy to make steady progress.
The CPM-B Solution
The CPM-B automatically moves the leg through smooth, repeatable flexion and extension cycles without requiring patient effort. This continuous passive motion promotes joint healing, reduces stiffness and swelling, and progressively restores the knee’s range of motion — whether in the hospital, rehab center, or at home. Patients simply relax while the machine does the work, making therapy consistent, pain-free and easy to repeat day after day.
Who It’s For
Post-operative patients — after knee replacement, ligament repair, fracture fixation and other lower limb surgeries
Stroke and hemiplegia patients — recovering leg movement and joint flexibility
Arthritis patients — managing joint stiffness and maintaining mobility
Injury recovery — ankle sprain, sprain, foot drop and other lower limb conditions
Care settings — hospital, rehab center, household care center and home use
Key Features
Wide Training Angle Range — adjustable from -5° to 120° for progressive, stage-by-stage range-of-motion recovery.
