DNA  is a molecule composed of two chains that coil around each other to form a double helix carrying genetic instructions for the development, functioning, growth and reproduction of all known organisms The two DNA strands are also known as polynucleotide . Each nucleotide is composed of one of four nitrogen-containing nucleobases (cytosine [C], guanine [G], adenine [A] or thymine [T]), a sugar called deoxyribose, and a phosphate group. The nucleotides are joined to one another in a chain by covalent bonds between the sugar of one nucleotide and the phosphate of the next, resulting in an alternating sugar-phosphate backbone.

The Continuous Passive Motion (CPM) System is a specialized medical device used primarily in physical therapy to help patients recover after surgery or injury by promoting joint mobility and preventing stiffness. This system works by gently moving a patient's joint through a controlled range of motion (ROM) without the need for voluntary muscle effort. It is commonly used in rehabilitation settings, particularly for knee, hip, and shoulder joints, following procedures such as joint replacement, ligament reconstruction, or arthroscopic surgery.

Key Features:

Continuous Motion Mechanism: The CPM system provides consistent, gentle, and rhythmic movement to the joint, allowing it to move through its full range of motion while reducing pain and swelling. This controlled motion helps maintain joint flexibility and minimizes the risk of complications such as adhesions or contractures.

Adjustable Range of Motion: The system allows therapists or medical practitioners to adjust the angle, speed, and duration of the joint movement according to the patient’s specific needs. This adjustability ensures that the system is suitable for various stages of recovery and can be tailored to individual treatment plans.
