With 0–120° adjustable angles, 10 speed levels, and an intelligent digital display, this professional-grade device offers both patients and healthcare providers a safe and customizable rehabilitation solution.

Whether used in a hospital, physiotherapy clinic, or home environment, this device combines ergonomic comfort, intelligent microcomputer control, and customizable therapy settings to ensure optimal rehabilitation outcomes.

What is a CPM Machine and Why is it Important?

Understanding Continuous Passive Motion (CPM)

A Continuous Passive Motion (CPM) machine is a device that gently and continuously moves a joint in a controlled range of motion. For knee rehabilitation, this means flexion and extension exercises that prevent stiffness, reduce scar tissue, and improve circulation.

Why Patients Need CPM Therapy

• Prevents joint stiffness after immobilization.

• Enhances blood circulation to promote healing.

• Reduces pain and swelling after surgery.

• Prevents formation of adhesions and scar tissue.

• Improves flexibility and range of motion.

Key Features 

1. Adjustable 0–120° Range of Motion

Patients can start from 0° (straight leg) and gradually progress to 120° flexion. This adjustable range ensures therapy is adapted to each stage of recovery.

2. Ten Adjustable Speed Settings

With 10 speed levels, therapists and patients can set the pace according to comfort and progress. Beginners may start at slower speeds, while advanced users can increase intensity for better outcomes.

3. Digital Screen Display

The built-in LCD display makes it easy to monitor time, angle, and speed during each session. This ensures accuracy and helps track patient progress.

4. Dual Exercise Modes

• Timing Mode: Fixed session durations for structured therapy.

• Mirror Mode: The machine mimics natural joint movement, providing a more flexible exercise pattern.

5. Wireless Remote Control

The remote allows users or therapists to adjust speed, angle, and duration effortlessly during sessions, reducing interruptions.

6. Safety-Oriented Design

Equipped with overload protection and an active memory function, the device automatically remembers the last settings, ensuring consistency and safety in repeated sessions.

7. Ergonomic and Adjustable Design

The machine features padded leg supports with adjustable straps, making it suitable for different leg lengths and providing maximum comfort during use.
