Limited Mobility and Reduced Range of Motion

What limited mobility means

Clinicians look at mobility in two ways:

• Joint range of motion (ROM): how far a joint moves. Active range is how far you can move it yourself. Passive range is how far it moves when someone else moves it. If both are limited, the joint itself is stiff (arthritis, frozen shoulder, scar tissue). If only active movement is limited, the problem is usually weakness, pain or a torn tendon.
• Functional mobility: your ability to walk, climb stairs, get in and out of bed or a chair, and keep your balance.

For abnormal movements such as tremor, jerks or slowness from brain disorders, see problems with movement.

Causes of limited range of motion

Joint causes

• Osteoarthritis: wear of joint cartilage, causing stiffness after rest, pain with use and gradual loss of movement, especially in knees, hips, hands and spine.
• Inflammatory arthritis: rheumatoid arthritis, psoriatic arthritis and ankylosing spondylitis cause swollen, stiff joints with prolonged morning stiffness.
• Frozen shoulder: the shoulder capsule thickens and tightens, causing pain and severe loss of movement in all directions. Common in people aged 40 to 60 and with diabetes.
• Injury: fractures, dislocations, ligament tears and swelling.
• Locked joint: a torn meniscus or loose body can physically block knee movement.
• Gout and pseudogout: sudden, painful, swollen joints.
• Septic arthritis: joint infection, an emergency.

Soft tissue causes

• Tendinitis and tendon tears, such as rotator cuff injuries, which limit active movement
• Bursitis: inflamed fluid sacs around joints, painful with movement
• Contractures: tightening of muscles, tendons or skin after long immobilization, burns, stroke or cerebral palsy
• Muscle strains and spasms

Spine causes

Back and neck problems, including disc disease, arthritis and spinal stenosis, cause stiffness and pain that limit bending, turning and walking distance.

Nerve and muscle causes

• Stroke, multiple sclerosis and Parkinson's disease cause weakness, stiffness (spasticity or rigidity) and balance problems.
• Peripheral neuropathy causes numb feet and unsteadiness.
• Muscle diseases: inflammatory myopathies, muscular dystrophies and polymyalgia rheumatica (shoulder and hip girdle stiffness in people over 50).

Whole-body causes

• Deconditioning: after illness, hospital stays or bed rest, muscles lose strength quickly. Older adults can lose a noticeable amount of leg strength within a week of bed rest.
• Sarcopenia: age-related loss of muscle mass and strength.
• Obesity, heart and lung disease, which limit stamina.
• Chronic pain and fear of movement.
• Medicines that cause dizziness, sedation or muscle aches.

Limited mobility in older adults

Reduced mobility is one of the strongest predictors of falls, loss of independence and hospital admission in older people. It often has several causes at once: arthritis, weak legs, poor vision, foot problems, dizziness and medicines. A doctor or physical therapist may check:

• Timed Up and Go: the time to stand from a chair, walk 3 meters (10 feet), turn and sit. Over 12 seconds suggests higher fall risk.
• Chair stand test: how many times you can stand up in 30 seconds without using your arms.
• Balance, walking pattern, foot health, vision and medicine list.

How doctors find the cause

You will be asked which movements are difficult, when it started, whether it is getting worse, about pain, morning stiffness, swelling, injury and other illnesses. The exam includes measuring the joint's range with a goniometer, comparing active and passive movement, testing strength and reflexes, and watching you walk.

Tests may include X-rays (arthritis, fractures), ultrasound or MRI (tendons, cartilage, nerves), blood tests for inflammation, rheumatoid factor, uric acid, thyroid and vitamin D, and nerve studies if weakness or numbness is present.

Treatment and ways to improve mobility

Physical therapy and exercise

Physical therapy is the foundation for almost every cause. A therapist will design:

• range-of-motion exercises to stretch stiff joints, done daily
• strengthening exercises, especially for the thighs, hips and core
• balance training such as tai chi, which reduces falls in older adults
• walking programs, starting short and building up

Gentle movement is usually better than rest. Avoiding movement because of pain often makes stiffness and weakness worse.

Treating the cause

• Pain relief so you can move: acetaminophen (paracetamol), topical NSAIDs or oral NSAIDs if safe for you
• Steroid injections for frozen shoulder, bursitis or arthritis flares
• Disease-modifying drugs for rheumatoid arthritis
• Surgery such as joint replacement, tendon repair or release of a frozen shoulder when conservative care fails

Aids and adaptations

• canes, walkers, rollators and wheelchairs, fitted by a therapist
• grab bars, raised toilet seats, shower chairs and stair rails
• occupational therapy for dressing, cooking and other daily tasks

Frequently asked questions

What causes limited range of motion?

Common causes are osteoarthritis, joint injuries, frozen shoulder, tendon tears, bursitis and muscle tightness. Inflammatory arthritis, stroke, Parkinson's disease, spinal stenosis and long periods of inactivity also reduce movement. The pattern of stiffness and pain helps identify the cause.

How can I improve limited mobility?

Regular range-of-motion stretches, strengthening exercises and walking, ideally guided by a physical therapist, are the most effective approach. Treat pain so you can move, and address the underlying cause, such as arthritis or frozen shoulder.

Can limited range of motion be restored?

Often, yes. Stiffness from injury, frozen shoulder or inactivity usually improves with physical therapy over weeks to months. Severe arthritis may need joint replacement to restore movement. Long-standing contractures are harder to reverse, so early treatment matters.

What is the difference between limited mobility and a movement disorder?

Limited mobility means you cannot move as far or as easily as normal, usually from joint, muscle or pain problems. A movement disorder means movements are abnormal, such as tremor, jerks or slowness, from problems in the brain's movement control systems.

When should I see a doctor for limited mobility?

See a doctor if stiffness or reduced movement lasts more than a few weeks, keeps getting worse, comes with joint swelling or long morning stiffness, or causes falls. Get emergency help for sudden weakness or inability to move a limb.
