What is morning stiffness
Morning stiffness is the sensation of "locked" joints after prolonged rest that resolves with movement. It is caused by accumulation of high-viscosity synovial fluid and periarticular soft-tissue swelling during sleep.
Short-lasting stiffness is not a disease in itself. But its duration, location and symmetry give the physician critical information about the nature of joint pathology.
Duration — the diagnostic key
Up to 5 minutes
Physiological norm. A brief "warm-up" after sleep is acceptable in healthy individuals. No workup required.
5–30 minutes
Typical of osteoarthritis. Resolves after a warm shower or light warm-up. Often worsens in the evening after loading.
More than 30–60 minutes
A sign of inflammatory disease: rheumatoid arthritis, psoriatic arthritis, spondyloarthritis, polymyalgia. Urgent rheumatology evaluation needed.
Main causes
Osteoarthritis
Cartilage degeneration. Short stiffness, most often in knees, hands, hips. Worsens after load. → Osteoarthritis treatment
Rheumatoid arthritis
Autoimmune systemic disease. Symmetrical involvement of small joints of hands and feet, stiffness over 1 hour. Requires early initiation of disease-modifying therapy.
Ankylosing spondylitis (Bekhterev's disease)
Inflammation of sacroiliac joints and spine. Morning back stiffness in young men, improves with movement. HLA-B27 positivity.
Psoriatic arthritis
In 30% of psoriasis patients. Asymmetric involvement, dactylitis ("sausage digit"), enthesitis. Moderate morning stiffness.
Polymyalgia rheumatica
Inflammatory disease of the elderly. Bilateral shoulder- and pelvic-girdle pain and stiffness over 45 minutes. High ESR. Rapid response to prednisolone.
Fibromyalgia and myofascial syndrome
Chronic musculoskeletal pain syndrome. Widespread stiffness, not due to synovitis. Distinguished from rheumatic diseases by normal inflammation markers.
Algorithmic diagnosis
Laboratory tests
ESR, CRP — inflammation markers. Rheumatoid factor, anti-CCP — for RA. Uric acid — for gout. ANA — for lupus. HLA-B27 — for spondyloarthritis.
Joint ultrasound with Doppler
Key method of early synovitis detection. Hypervascularization is a sign of active inflammation. Distinguishes arthritis from osteoarthritis before MRI changes appear.
MRI and X-ray
MRI — for cartilage, meniscus, ligaments and early erosions. X-ray — for joint space narrowing, osteophytes, bony erosions. Usually done after diagnosis clarification.
Treatment by cause
MIBRAR® does not replace disease-modifying therapy for inflammatory arthritis, but it successfully regenerates tissue damaged by inflammation and is highly effective for osteoarthritis.

Up to 5 min — normal. 15–30 min — osteoarthritis. Over 30–60 min — inflammatory arthritis, urgent rheumatology.
Osteoarthritis — short, worse in evening. Arthritis — prolonged with swelling and redness, improves with movement.
ESR, CRP, RF, anti-CCP, uric acid, ANA. Joint ultrasound with Doppler.
Doesn't replace DMARDs, but restores damaged joints alongside rheumatology treatment.
Stiffness over 30 min — rheumatologist. Short + load-related pain — orthopedist.
