Stiffness: Clinical Meaning

Rheumatoid Arthritis

Rheumatoid arthritis (RA) is a chronic autoimmune disease that causes inflammation in the joints, leading to pain, swelling, and eventual joint damage. Unlike osteoarthritis, RA is systemic and can affect organs including the heart and lungs.

Osteoarthritis

Osteoarthritis is the most common form of arthritis, caused by the gradual breakdown of cartilage in joints. It primarily affects the knees, hips, hands, and spine, causing pain, stiffness, and reduced range of motion.

Parkinson's Disease

Parkinson's disease is a progressive neurological disorder affecting movement, caused by the loss of dopamine-producing neurons. Symptoms include tremor, rigidity, slowness of movement, and balance problems. There is no cure, but treatments can manage symptoms.

Ankylosing Spondylitis

Ankylosing spondylitis is a type of inflammatory arthritis primarily affecting the spine and sacroiliac joints. It causes chronic pain and stiffness in the lower back and can lead to fusion of spinal vertebrae. It is more common in men.

Psoriasis

Psoriasis is a chronic autoimmune skin condition that causes rapid skin cell turnover, resulting in thick, red, scaly patches (plaques). It can affect any part of the body and is associated with psoriatic arthritis. Stress, infections, and certain medications can trigger flares.

Tendinitis

Tendinitis is inflammation of a tendon, most commonly affecting the shoulder (rotator cuff), elbow (tennis/golfer's elbow), Achilles tendon, and patellar tendon. It causes localized pain worsening with activity; eccentric exercises and load management are key treatments.

Frozen Shoulder (Adhesive Capsulitis)

Frozen shoulder is characterized by progressive pain and stiffness of the shoulder joint, eventually leading to severe restriction of movement. It goes through freezing, frozen, and thawing phases; physiotherapy, corticosteroid injections, and distension arthrography are treatments.

Meniscus Tear

A meniscus tear is damage to the fibrocartilage of the knee, causing pain, swelling, stiffness, and clicking or locking. It commonly occurs during twisting injuries; treatment depends on tear type (conservative vs. surgical repair).

Psoriatic Arthritis

Psoriatic arthritis is inflammatory arthritis affecting some people with psoriasis. It causes joint pain, stiffness and swelling ranging from mild to severe with potential for joint damage.
