A musculoskeletal assessment is a physical examination used to evaluate the bones, muscles, joints, posture, movement, strength and mobility of a patient. It helps nurses and healthcare providers understand how well a person can move, walk, balance, use assistive devices and perform activities of daily living, also called ADLs.
ADLs include basic self-care activities such as bathing, dressing, toileting, transferring, walking and eating. These skills show whether a patient can care for themselves safely or needs support. A musculoskeletal assessment is especially important after falls, surgery, fractures, stroke, chronic pain, arthritis, nerve disease or long periods of bed rest.
The assessment usually includes two main steps: inspection and palpation. During inspection, the nurse observes posture, stance, gait, balance, spinal curvature and pain during active movement. During palpation, the nurse checks muscles and joints for warmth, swelling, tenderness and abnormal findings. Range of motion, muscle strength and movement quality are also assessed.
What Is a Musculoskeletal Assessment?
A musculoskeletal assessment is a structured check of the body’s movement and support system. It evaluates how bones, joints, muscles and connective tissues function together.
A musculoskeletal exam commonly includes observation, palpation, range of motion testing and strength testing. StatPearls explains that observation begins by checking visible abnormalities, while palpation helps identify tenderness, pain, trigger points and other musculoskeletal findings.
The goal is not only to find injury. The goal is to understand how the patient moves in real life.
Why Musculoskeletal Assessment Is Important
Musculoskeletal assessment helps identify:
- Pain
- Weakness
- Joint stiffness
- Swelling
- Poor balance
- Abnormal gait
- Fall risk
- Limited mobility
- Loss of independence
- Need for assistive devices
- Problems with ADLs
A good assessment helps guide care planning, rehabilitation, safety precautions and referrals.
Activities of Daily Living
Activities of daily living, or ADLs, are basic tasks needed for independent self-care. StatPearls describes basic ADLs as skills needed to manage physical needs, including personal hygiene, dressing, toileting, transferring or ambulating and eating.
Common ADLs include:
| ADL | Meaning |
|---|---|
| Bathing | Washing the body safely |
| Dressing | Putting on and removing clothes |
| Getting out of bed | Moving from bed to standing or chair |
| Walking | Moving safely from place to place |
| Eating | Feeding oneself |
| Using the bathroom | Toileting and hygiene |
ADL assessment shows whether the patient is independent, needs partial help or needs full assistance.
Questions to Ask the Patient
Before touching or moving the patient, ask focused questions. These questions give clues about safety, function and mobility limits.
Important questions include:
- Do you use any assistive devices, such as a cane, walker or brace?
- Have you had any recent falls?
- Do you need help with daily tasks?
- Do you have pain when walking or moving?
- Do you feel weak on one side?
- Do you feel dizzy when standing?
- Can you climb stairs?
- Can you bathe and dress without help?
- Have you had recent surgery or injury?
- Do you have numbness, tingling or joint stiffness?
These questions help the nurse decide how much help the patient needs during assessment.
Step 1: Inspection
Inspection means observing the patient without touching them first. It starts the moment the patient enters the room or changes position.
Inspect for:
- Posture
- Overall stance
- Gait
- Balance
- Spinal curvature
- Joint alignment
- Muscle size
- Swelling
- Deformity
- Tremors
- Pain with active ROM
- Use of assistive devices
The patient’s movement often gives more information than one isolated joint test.
Posture and Overall Stance
Posture shows how the body holds itself against gravity.
Look for:
- Forward head posture
- Rounded shoulders
- Uneven shoulder height
- Scoliosis signs
- Kyphosis
- Lordosis
- Uneven hips
- Leaning to one side
- Guarding due to pain
Poor posture may be caused by pain, weakness, spinal disease, neurological issues or long-term habits.
Gait and Balance
Gait means walking pattern. Balance shows how safely the patient can stand and move.
Observe:
- Step length
- Foot clearance
- Limping
- Shuffling
- Use of cane or walker
- Arm swing
- Turning ability
- Steadiness
- Fear of falling
A slow or unsteady gait increases fall risk.
Spinal Curvature
Inspect the spine from the side and back when appropriate.
Common abnormal curves include:
| Finding | Description |
| Kyphosis | Excessive outward curve of upper spine |
| Lordosis | Excessive inward curve of lower spine |
| Scoliosis | Lateral curve of the spine |
Spinal curvature may affect breathing, pain, gait and daily mobility.
Step 2: Palpation
Palpation means using the hands to feel muscles, bones and joints. It helps detect abnormal temperature, swelling, tenderness and tissue changes.
During musculoskeletal assessment, palpation is often done with inspection. Nursing Skills from NCBI notes that joints are palpated for warmth, swelling or tenderness, and passive ROM may be performed if active ROM is decreased.
Palpate for:
- Warmth
- Swelling
- Tenderness
- Crepitus
- Muscle spasm
- Masses
- Joint enlargement
- Pain response
- Symmetry
Always compare both sides when possible.
Range of Motion
Range of motion, or ROM, means how far and in what direction a joint can move.
ROM helps assess:
- Joint flexibility
- Muscle function
- Pain limits
- Neurological control
- Joint stiffness
- Functional ability
There are two main types:
- Active ROM
- Passive ROM
Active Range of Motion
Active ROM is movement performed by the patient.
Example:
The nurse asks the patient to raise an arm, bend the knee or turn the head.
Active ROM requires:
- Muscle contraction
- Joint movement
- Nerve control
- Patient cooperation
Pain during active ROM may suggest muscle, tendon, joint or nerve involvement.
Passive Range of Motion
Passive ROM is movement performed by the examiner or outside force. The patient stays relaxed.
Passive ROM helps assess joint movement when the patient cannot move actively or has weakness.
NCBI describes active and passive ROM testing as part of the musculoskeletal examination and notes that true joint inflammation may restrict both active and passive ROM.
Active ROM vs Passive ROM
| Feature | Active ROM | Passive ROM |
| Who moves the joint? | Patient | Examiner |
| Muscle contraction | Present | Not required |
| Tests | Strength, control and joint motion | Joint flexibility and restriction |
| Pain meaning | Muscle, tendon or joint issue | Joint or soft tissue restriction |
| Used when | Patient can move | Patient has weakness or limited movement |
If active ROM is limited but passive ROM is normal, weakness or pain may be the main issue. If both are limited, joint disease or structural restriction may be present.
Muscle Strength Assessment
Muscle strength testing checks how strongly a patient can move against gravity and resistance.
It helps detect:
- Weakness
- Nerve damage
- Stroke effects
- Muscle disease
- Deconditioning
- Injury recovery
- Functional decline
The Medical Research Council scale is widely used for clinical muscle strength grading. It scores strength from 0 to 5 based on visible contraction, movement, gravity and resistance.
Muscle Strength Scale
| Grade | Meaning |
| 5 | Normal movement against gravity and full resistance |
| 4 | Movement against moderate resistance |
| 3 | Movement against gravity but not resistance |
| 2 | Movement only when gravity is eliminated |
| 1 | Muscle contraction present, but no movement |
| 0 | No movement or contraction |
How to Test Muscle Strength
Test both sides of the body and compare.
Common strength checks include:
- Hand grip
- Shoulder push and pull
- Elbow flexion and extension
- Hip flexion
- Knee extension
- Foot dorsiflexion
- Foot plantar flexion
Document the score clearly.
Example:
Upper extremity strength 5/5 bilaterally.
This means normal strength on both sides.
Factors Affecting Physical Mobility
Physical mobility can be affected by anything that damages the musculoskeletal system or reduces the ability to control movement.
Common factors include:
- Aging
- Sedentary lifestyle
- Recent surgery
- Pain
- Obesity
- Malnutrition
- Fractures
- Injury
- Nerve degeneration
- Diabetes
- Multiple sclerosis
- Stroke
- Osteoarthritis
- Sedative medications
- Muscle atrophy
Non-musculoskeletal factors can also reduce safe mobility. Orthostatic hypotension and shortness of breath can make walking unsafe even when muscles and joints are intact.
Aging and Mobility
Aging can reduce muscle mass, balance, flexibility and bone density. Older adults may also have arthritis, vision changes or fear of falling.
Assessment should focus on safety, independence and fall prevention.
Sedentary Lifestyle
Long periods of inactivity weaken muscles and reduce endurance. This can make walking, climbing stairs and transfers harder.
Even short daily movement helps maintain function.
Recent Surgery
Surgery can temporarily reduce mobility due to pain, anesthesia effects, weakness, drains, dressings or movement restrictions.
Assess:
- Weight-bearing status
- Pain level
- Surgical precautions
- Assistive device need
- Fall risk
Pain
Pain limits movement and can cause guarding.
Assess:
- Location
- Severity
- Timing
- Trigger
- Relief factors
- Effect on walking or ADLs
Pain during movement should never be ignored.
Nerve Degeneration and Neurological Disease
Nerve conditions can reduce strength, coordination and sensation.
Examples include:
- Diabetes-related neuropathy
- Stroke
- Multiple sclerosis
- Spinal cord injury
- Peripheral nerve injury
Neurological problems may cause weakness, foot drop, poor balance or unsafe gait.
Bone Degeneration and Osteoarthritis
Osteoarthritis causes joint cartilage breakdown and joint stiffness. It often affects knees, hips, hands and spine.
Common signs include:
- Pain with use
- Morning stiffness
- Reduced ROM
- Joint enlargement
- Crepitus
- Functional limitation
Types of Movement
Movement terms describe how joints move. These terms are important for assessment, charting and rehabilitation.
| Movement | Meaning |
| Flexion | Bending a joint |
| Extension | Straightening a joint |
| Adduction | Moving toward the midline |
| Abduction | Moving away from the midline |
| Internal rotation | Rotating toward the midline |
| External rotation | Rotating away from the midline |
| Pronation | Turning palm or foot downward |
| Supination | Turning palm or foot upward |
| Circumduction | Moving in a circular pattern |
| Plantar flexion | Pointing toes downward |
| Dorsiflexion | Pulling toes upward toward the head |
Flexion and Extension
Flexion means bending a joint. For example, bending the elbow.
Extension means straightening a joint. For example, straightening the knee.
These are common movements tested in elbows, knees, fingers and hips.
Abduction and Adduction
Abduction means moving a limb away from the midline.
Adduction means moving a limb toward the midline.
Memory tip:
Abduction means away. Adduction means adding back to the body.
Internal and External Rotation
Internal rotation means turning toward the midline.
External rotation means turning away from the midline.
These movements are commonly tested at the shoulder and hip.
Pronation and Supination
Pronation means turning the palm downward.
Supination means turning the palm upward.
Memory tip:
When holding soup, your palm is up. That is supination.
Plantar Flexion and Dorsiflexion
Plantar flexion means pointing the toes downward, like standing on tiptoe.
Dorsiflexion means pulling the toes upward toward the head.
These movements are important for walking, balance and fall risk assessment.
Musculoskeletal Assessment Sequence
A practical assessment follows a simple flow.
- Ask about pain, falls, devices and ADLs.
- Inspect posture, stance and gait.
- Inspect joints and muscles for swelling or deformity.
- Palpate for warmth, tenderness and swelling.
- Assess active ROM.
- Assess passive ROM if needed.
- Test muscle strength.
- Compare both sides.
- Assess mobility and fall risk.
- Document findings clearly.
Nursing Documentation Examples
Clear documentation helps the care team understand patient status.
Examples:
| Finding | Documentation Example |
| Normal strength | Strength 5/5 in upper and lower extremities bilaterally |
| Mild weakness | Right lower extremity strength 4/5 |
| No movement | Left arm strength 0/5 |
| Pain with movement | Reports right shoulder pain during active abduction |
| Swelling | Mild swelling noted at left knee |
| Gait issue | Unsteady gait, uses walker with one-person assist |
| ROM limit | Decreased active ROM in right hip due to pain |
Avoid vague phrases. Write what you saw, felt and tested.
Safety During Musculoskeletal Assessment
Safety matters during every mobility check.
Use these precautions:
- Lock bed wheels
- Keep bed low
- Use nonskid footwear
- Clear floor hazards
- Stand near weak side
- Use gait belt when needed
- Do not force painful ROM
- Stop if dizziness occurs
- Assist with transfers
- Follow weight-bearing orders
Patients with recent falls, weakness, dizziness or sedative use need closer supervision.
Red Flags During Assessment
Report urgent findings such as:
- Sudden weakness
- New loss of movement
- Severe pain after injury
- Obvious deformity
- Numbness with weakness
- Loss of pulse in limb
- Cold, pale extremity
- New inability to walk
- Suspected fracture
- Severe back pain with bowel or bladder changes
These findings may need immediate medical review.

FAQs
1. What is a musculoskeletal assessment?
A musculoskeletal assessment is an exam of bones, muscles, joints, posture, movement and strength. It helps identify pain, weakness, stiffness, swelling, gait problems and fall risk. Nurses also use it to assess how well a patient performs daily activities. It is common after injury, surgery, falls, stroke or mobility decline.
2. Why is musculoskeletal assessment important?
It shows whether a patient can move safely and care for themselves. It helps detect problems that affect walking, bathing, dressing, eating and transfers. It also guides fall precautions, rehabilitation and assistive device planning. Early assessment can prevent complications from immobility.
3. What are ADLs in musculoskeletal assessment?
ADLs are activities of daily living. They include bathing, dressing, toileting, eating, walking and getting out of bed. These tasks show a patient’s level of independence. If ADLs are limited, the patient may need support, therapy or safety planning.
4. What questions should nurses ask before assessment?
Ask whether the patient uses a cane, walker, brace or other assistive device. Ask about recent falls, pain, weakness and difficulty with daily tasks. Also ask about recent surgery, fractures, numbness and dizziness. These answers help prevent unsafe movement during assessment.
5. What is active range of motion?
Active range of motion means the patient moves the joint using their own muscles. It tests movement, strength, nerve control and pain response. For example, asking the patient to raise their arm is active ROM. Pain or weakness during active ROM should be documented.
6. What is passive range of motion?
Passive range of motion means the examiner moves the patient’s joint while the patient relaxes. It checks joint flexibility and restriction when the patient cannot move well independently. It does not require muscle contraction. Passive ROM should be gentle and never forced.
7. What is the muscle strength scale?
The muscle strength scale grades strength from 0 to 5. Grade 5 means normal movement against gravity and resistance. Grade 3 means movement against gravity but not resistance. Grade 0 means no movement or visible contraction.
8. What factors affect physical mobility?
Physical mobility can be affected by aging, pain, fractures, surgery, obesity, malnutrition, muscle atrophy and sedentary lifestyle. Nerve conditions such as stroke, multiple sclerosis and diabetic neuropathy can also reduce movement control. Medications such as sedatives may increase fall risk. Shortness of breath or orthostatic hypotension can also limit safe mobility.
9. What are the main types of movement?
The main movements include flexion, extension, abduction, adduction, internal rotation, external rotation, pronation, supination, circumduction, plantar flexion and dorsiflexion. These terms describe how joints move. They are used in assessment and documentation. Knowing them helps describe mobility clearly.
10. What should be documented after a musculoskeletal assessment?
Document pain, posture, gait, balance, swelling, tenderness, range of motion and muscle strength. Include side-to-side differences and assistive device use. Record strength using the 0 to 5 scale. Also document safety concerns, fall risk and the patient’s ability to perform ADLs.
