Ankylosing spondylitis (AS) is a chronic inflammatory disease that leads to gradual stiffness and fusion of the joints in the spine.

Rheumatoid arthritis (RA) is a chronic autoimmune disease in which the immune system attacks the joints, causing inflammation. It manifests as pain, swelling, stiffness and joint damage, leading to reduced mobility.

Regeneration in sports is the process of restoring the body to full functionality after physical exertion, often following injuries or strain on muscles and tendons. It involves rest, proper diet and hydration. Regeneration helps prevent injuries and improves athletic performance.

Tennis elbow is an inflammatory condition of the tendons around the lateral epicondyle of the humerus, usually caused by overuse. It manifests as pain and tenderness on the outer side of the elbow, especially when gripping or lifting objects. Although it commonly affects tennis players, it can occur in anyone performing repetitive hand movements.

Joint pain can be the result of inflammation, injuries, joint degeneration or autoimmune diseases. It is characterized by stiffness, swelling and limited mobility.

Neck pain is a discomfort occurring in the neck area, often associated with muscle tension, poor posture, stress or injuries. It may be accompanied by stiffness, limited range of motion, and pain radiating to the shoulders.

Hip pain can be caused by an injury, arthritis, strain or degenerative disease. It is characterized by pain, stiffness and difficulty moving the leg.

Muscle weakness is the loss of muscle strength, making it difficult to perform daily activities. It can result from various causes, such as neurological diseases, injuries, or lack of activity.

Carpal tunnel syndrome is a condition in which there is pressure on the median nerve in the carpal tunnel, leading to pain, numbness, and weakness in the hand.

Sciatica is pain that radiates along the sciatic nerve, which runs from the lower back down to the legs. It is most often caused by compression or irritation of the nerve roots in the lumbar-sacral region of the spine, leading to pain, numbness and muscle weakness.

Regeneration of joints, tendons, ligaments and skin is the natural healing and tissue rebuilding process after injuries or overuse. These processes involve the repair of damaged tissues, reducing inflammation and restoring function to the affected areas.

Osteoarthritis (degenerative joint disease) is a chronic condition in which the cartilage in the joints wears down, leading to pain, stiffness, and reduced joint mobility. It most commonly affects the knee, hip and spine joints.

Back pain is a condition that can result from muscle tension, injuries, spine issues, intervertebral discs problems or inflammation.

Joint stiffness is difficulty moving the joints, characterized by a lack of flexibility and limited range of motion. It can result from inflammatory conditions such as rheumatoid arthritis, osteoarthritis or previous injuries.

Numbness in the limbs is a sensation of loss of feeling, weakness or a "cold" sensation.

Arthritis is a condition in which inflammation occurs within the joints, causing pain, swelling, stiffness and limited range of motion.

Rheumatism is a general term used to describe various musculoskeletal disorders that cause pain, stiffness, and inflammation in the joints and soft tissues. It can include conditions such as rheumatoid arthritis, osteoarthritis and fibromyalgia.

Tendon sheath inflammation is an inflammatory condition of the membrane surrounding a tendon, causing pain, swelling and limited mobility in the affected joint. It can occur due to excessive exertion, injury, infection or autoimmune diseases. Symptoms include pain during movement, stiffness and swelling at the site of inflammation.

Bone pain is a discomfort felt in the bones, which can result from injuries, infections, inflammations, osteoporosis, tumors or other conditions.

Muscle cramps are sudden, involuntary and painful contractions of muscle fibers, which can last from a few seconds to several minutes.

Knee pain is a condition associated with injuries, inflammation, strain or joint damage. It is characterized by pain, swelling, stiffness and difficulty moving the knee joint.

Tingling in the limbs is the sensation of prickling, or itching of the skin, often resulting from pressure on the nerves, circulation problems, nerve damage, or neurological conditions.
