What is a Continuous Passive Motion Machine?

CPM machine (Continuous Passive Motion Machine) is a motorized physical therapy equipment used to recover a joint after extensive surgery. A CPM machine brings down blood and fluid accumulation in and around the joints that may occur after surgery or due to trauma. It also maintains normal motion of the knee after a knee replacement surgery. These devices provide an effective post-operative range of motion for the knees, ankles, hip joints, wrists, or hands with minimal effort. We carry a range of high-quality CPM Machines for Sale from top manufacturers like Kinetic USA, Chattanooga Group, Bodymed, and Patterson Medical.

Benefits of CPM Machine

In the post-operative stiffness stages, the machine pumps the accumulated blood and edema fluid away from the periarticular tissues and the affected joint. This prevents subsequent joint stiffness in the first few hours or days of the surgery, reducing the risks of joint fibrosis and contracture. Joint motion is important to ensure the health of the articular cartilage and is considered timely care of the joint to ensure long-term mobility.
Some other benefits are:

Pain Relief
Decrease the duration of stays in hospitals
Decrease the need for manual joint movement when individuals are under anesthetic

How Does a CPM Machine Work?

This physiotherapy equipment works the joint through a range of motion (ROM) without any effort from the user. The affected joint, like the knee, elbow, wrist, ankle, hand, and wrist, is placed in a mechanical split and moved constantly without normal muscle function. Understanding how long it takes to use a continuous passive motion machine will depend on the condition of the affected joint and when the patient is able to perform the movement without assistance. Usually, the surgeon puts the patient on the machine after the surgery and makes him continue until 3-4 weeks following surgery.

How can a continuous passive motion machine help with healing?

A CPM machine may help a person recover from surgery or injury in the following ways:

It helps increase the arm's or leg's range of motion (ROM).
Muscles may get stronger more quickly.
Gently exercise arm and leg muscles to prevent them from getting weak.
Tendons and ligaments, the tissue that connects your muscles and bones, may also get stronger using a CPM.
It decreases swelling, which results in less pain.
It may have increased blood flow in your arm or leg, which results in faster healing.

How to Use CPM Machine?

Most continuous passive machine therapy starts in the hospital and continues at home. Physiotherapists may work differently depending on their patients’ conditions. Some may recommend starting at a pre-defined flexion (usually between 0-60 degrees) and increasing flexion by 5-10 degrees each day until it reaches 110. Another may use 0 to 40 degrees to start with. The general recommendation is to use the machine thrice daily, with each session lasting two hours for a total of six hours each day.

Place your CPM device against a heavy object or headboard. While you use it, this will keep it from moving.
Plug the CPM machine into it. To prevent falls, move the cord underneath the bed or tie it to the ground.
Before using a CPM unit, you may need to remove a shoulder or a knee immobilizer. Ask your healthcare professional how an immobilizer can be removed.
When using CPM for knee
- Place your leg so that the center of your knee rests where the machine bends, and the bottom of the foot is against the foot pad.
- Attach the leg to the machine by wrapping the machine's straps around the thigh, shin, and foot.
When using CPM for shoulder
- Position the elbow so that it rests where the CPM bends. Place your hand around the handgrip.
- Attach the arm to the machine by wrapping the machine's strap around the lower arm.

Types of Continuous Passive Motion Machine

Knee CPM
- Knee CPM machines are popular for their use after knee surgery or knee replacement procedures. They quickly get the patient out of the hospital and back on their feet.
- The Kinetec Spectra is an example of an effective continuous passive motion knee machine. It bends the knee in a slow and rhythmic motion without activating the leg muscles. This improves circulation, lubricating the affected joint. The extra fluid that has built up is moved away, and cartilage regeneration is encouraged.
- This physical therapy equipment is designed to accommodate patients ages eight to 80 without requiring additional accessories. It is exceptionally easy to carry and offers a quick set-up.
Shoulder CPM
Suppose you are looking for shoulder comfort therapy. In that case, the Patient Kit for Artromot S3 Shoulder CPM Machine from Chattanooga is popular for its deep pile sheepskin and durable fleece. It includes items for both the upper and lower arms of the unit.
Hand CPM/Wrist CPM
The Kinetec Maestra Hand and Wrist CPM Machine is an effective CPM device for the hand and wrist. It is popular because of its lightweight and portability features. It has variable speed control, a range of motion, and pivoting palm support for increased comfort.
Ankle CPM
The Breva Ankle CPM Device from Kinetec USA is designed for the ankle. It offers two possible dimensional movements - Plantar flexion to Dorsiflexion and Eversion to Inversion patterns. It is a quiet machine and provides the flexibility of lying in bed or sitting in a chair. These CPM machines are a cost-effective way of overcoming joint stiffness and related complications post-surgery, thus eliminating prolonged physiotherapy or hospital visits.

Frequently Asked Questions

How many hours a day should you use a CPM machine?
The duration of using a CPM machine should align with your healthcare provider's recommendation. Typically, this spans about four hours daily for three to four weeks following surgery, although the specific timeframe may vary depending on the type of procedure undergone.
What areas of the body can derive benefits from utilizing a continuous passive motion machine?
CPM Devices can provide benefits to various body parts, including joints such as the knee, shoulder, elbow, and ankle. They are commonly used post-surgery or injury to promote joint flexibility, reduce stiffness, improve circulation, and facilitate healing.
Is it OK to sleep in a CPM machine?
It is not recommended to sleep in this machine because it will constantly repeat the motion of sliding your foot up towards your body, bending at your knee and hip to the predetermined amount of motion while the machine is turned on.
