Spinal Stenosis (Thoracolumbar) C&P Exam Prep

Forward Flexion (Active)

What it measures: Degrees of forward bend from neutral; normal is 0-90 degrees

What to expect: You will be asked to bend forward at the waist as far as pain allows. The examiner will measure the stopping point in degrees. This is the single most important measurement for rating purposes.

Pain considerations: Inform the examiner of any pain that begins before the end of the range of motion, pain that increases with continued motion, and any radiating pain down the legs triggered by flexion. Per DeLuca v. Brown, pain on motion must be noted even if it does not limit degrees.

Extension (Active)

What it measures: Degrees of backward bend from neutral; normal is 0-30 degrees

What to expect: You will be asked to lean backward. The examiner notes degree and pain onset.

Pain considerations: Spinal stenosis characteristically worsens with extension and is relieved by flexion. Clearly communicate any leg pain, weakness, or cramping that occurs when you lean backward.

Right and Left Lateral Flexion (Active)

What it measures: Degrees of side bending; normal is 0-30 degrees each side

What to expect: You will be asked to slide your hand down the side of your leg toward your knee on each side.

Pain considerations: Note if lateral flexion to one side reproduces or worsens radicular symptoms into either leg.

Right and Left Lateral Rotation (Active)

What it measures: Degrees of torso rotation; normal is 0-30 degrees each side

What to expect: Usually tested seated to isolate thoracolumbar motion.

Pain considerations: Note if rotation triggers or worsens any radiating symptoms.

Passive Range of Motion

What it measures: Range of motion when the examiner moves the joint without your muscle effort; compared to active ROM

What to expect: The examiner may gently assist your movement to determine if passive range exceeds active range, which indicates pain-limited active motion rather than structural limitation.

Pain considerations: Even if passive ROM is greater, report any pain produced by passive movement.

Repetitive Use Testing (3 Repetitions)

What it measures: Whether range of motion decreases after three repetitions of motion due to pain, weakness, or fatigue

What to expect: You may be asked to perform the same motion three times in succession. The examiner measures whether your range of motion decreases with repeated movement.

Pain considerations: Per DeLuca v. Brown, functional loss from pain, fatigability, or incoordination on repetitive use must be considered in the rating even if measured ROM does not change.

Straight Leg Raise (SLR)

What it measures: Nerve root tension - positive test suggests L4-S1 radiculopathy

What to expect: While lying flat, the examiner raises each leg individually with the knee straight. A positive test reproduces radiating pain below the knee.

Pain considerations: Even if the SLR does not reproduce pain at the exam, describe your typical radicular symptoms to the examiner.

Deep Tendon Reflex Testing

What it measures: Neurological integrity of specific nerve roots - patellar (L4), Achilles (S1)

What to expect: The examiner will tap your knee and ankle tendons with a reflex hammer while you are seated or lying down.

Pain considerations: Reflex loss is an objective finding that corroborates subjective pain symptoms.

Sensory Testing (Dermatomal)

What it measures: Sensation in specific nerve root distributions of the lower extremities

What to expect: The examiner may use a pin, tuning fork, or light touch to test sensation in specific areas of your legs and feet.

Pain considerations: Intermittent sensory symptoms are still real and ratable; mention your typical pattern even if sensation appears intact at exam.

Muscle Strength Grading (Manual Muscle Testing)

What it measures: Motor function of lower extremity muscle groups by nerve root level

What to expect: The examiner will ask you to push or pull against resistance with your feet, ankles, and legs to grade muscle strength on a 0-5 scale.

Pain considerations: Pain-limited effort should be described to the examiner so it can be distinguished from true neurological weakness.

Muscle Atrophy Measurement

What it measures: Circumferential measurement of thigh and calf to detect muscle wasting from disuse or denervation

What to expect: The examiner may measure the circumference of both thighs and both calves with a tape measure and compare sides.

Pain considerations: Disuse atrophy secondary to pain-avoidant movement patterns is a legitimate clinical finding.

10%

Forward flexion of the thoracolumbar spine greater than 60 degrees but not greater than 85 degrees; OR, combined range of motion of the thoracolumbar spine greater than 120 degrees but not greater than 235 degrees; OR, muscle spasm, guarding, or localized tenderness not resulting in abnormal gait or abnormal spinal contour; OR, vertebral body fracture with loss of 50 percent or more of height.

From 38 CFR: Under 38 CFR 4.71a, DC 5238 rates analogously to the General Rating Formula for Diseases and Injuries of the Spine. At 10%, the primary indicator is forward flexion limited to more than 60 but not more than 85 degrees or combined ROM more than 120 but not more than 235 degrees, or pain/spasm/tenderness without structural gait change.

20%

Forward flexion of the thoracolumbar spine greater than 30 degrees but not greater than 60 degrees; OR, the combined range of motion of the thoracolumbar spine not greater than 120 degrees; OR, muscle spasm or guarding severe enough to result in an abnormal gait or abnormal spinal contour such as scoliosis, reversed lordosis, or abnormal kyphosis.

From 38 CFR: Under 38 CFR 4.71a DC 5238, the 20% level requires forward flexion limited to the 31-60 degree range or severe muscle spasm causing observable gait or postural abnormality. Spinal stenosis commonly produces this level through combined structural limitation and neurogenic claudication.

40%

Forward flexion of the thoracolumbar spine to 30 degrees or less; OR, favorable ankylosis of the entire thoracolumbar spine.

From 38 CFR: At the 40% level under 38 CFR 4.71a DC 5238, forward flexion must be 30 degrees or less, which represents near-complete loss of lumbar flexibility. This level also includes favorable ankylosis (fused in a neutral or near-neutral position). For spinal stenosis, this is often accompanied by severe neurogenic claudication.

50%

Unfavorable ankylosis of the entire thoracolumbar spine (fused in flexion, extreme lateral, or forward flexed position causing disability).

From 38 CFR: 50% requires unfavorable ankylosis of the entire thoracolumbar spine under 38 CFR 4.71a. Unfavorable means the spine is fused in a position that causes significant functional disadvantage, such as a flexed or laterally deviated posture.

100%

Unfavorable ankylosis of the entire spine (both thoracolumbar and cervical regions). This is an extremely severe rating reserved for complete spinal fusion in unfavorable position affecting the full spinal column.

From 38 CFR: 100% for unfavorable ankylosis of the entire spine under 38 CFR 4.71a requires involvement of both the thoracolumbar and cervical spine segments in an unfavorable position.

Pain Quality and Location

How to describe it: Describe the pain as specifically as possible: location (e.g., central low back, bilateral, radiating), character (e.g., dull, aching, sharp, burning, electric), and what makes it better or worse. Spinal stenosis typically causes pain that worsens with standing and walking and improves with sitting or bending forward.

Example: On my worst days, I wake up with a 7 out of 10 burning pain across my low back that radiates down both legs to my calves. I cannot stand at the kitchen counter for more than 3 minutes before the leg cramping and burning forces me to sit or lean on a cart. I need to rest for 10-15 minutes before I can walk again.

Examiner listens for: Neurogenic claudication pattern (pain/cramping/weakness in legs with walking that is relieved by flexion or sitting), dermatomal radiation patterns, constant vs. intermittent pain, pain at rest vs. with activity.

Avoid: Saying 'it's just a little sore' or 'I manage okay' minimizes your actual limitations. Describe your worst typical days, not your best.

Neurogenic Claudication

How to describe it: Describe the specific distance or time you can walk before leg symptoms force you to stop, what those symptoms feel like (cramping, heaviness, burning, weakness), and how long you must rest or what position you must adopt before symptoms subside.

Example: I can only walk about half a block - roughly 200 feet - before both legs feel like lead, start cramping, and I get a burning numbness from my thighs to my feet. I have to stop and lean on a shopping cart or sit on a bench for at least 5-10 minutes before the leg symptoms ease enough to walk again. At the grocery store I have to use an electric cart because I cannot walk the full aisle.

Examiner listens for: Specific walking distance limitation, relief with forward flexion or sitting (classic spinal stenosis), bilateral vs. unilateral symptoms, differentiation from vascular claudication.

Avoid: Not mentioning the distance limitation or saying you 'eventually' get leg symptoms. Quantify: 'I cannot walk more than X feet without having to stop.'

Flare-Up Description

How to describe it: Describe what triggers a flare, how often flare-ups occur, how long they last, what the peak symptoms are during a flare, and how flares affect your ability to function - including any incapacitating episodes requiring bed rest.

Example: I have severe flare-ups 3-4 times per month, usually triggered by any activity involving prolonged standing or walking, like going to a family event or mowing the lawn. During a flare, my back pain reaches 9 out of 10 and I cannot get out of bed without my wife's help. The leg weakness and pain are so severe I cannot walk to the bathroom unaided. These episodes last 2-4 days where I am essentially bedridden.

Examiner listens for: Frequency, duration, and severity of flares; whether flares cause incapacitation (relevant for intervertebral disc syndrome rating under 5243 if applicable); triggers for flares; recovery time.

Avoid: Failing to mention flare-ups entirely because you feel 'okay today.' The examiner must document your flare-up history.

Functional Loss in Daily Activities

How to describe it: Use concrete, specific examples of activities you can no longer do or can only do with difficulty or pain. Reference activities of daily living, work, household tasks, recreation, and social activities.

Example: I can no longer: stand at the stove long enough to cook a full meal without sitting every few minutes; attend my grandchildren's school events because I cannot sit or stand for extended periods; perform yard work I did for 30 years; carry groceries from the car; drive for more than 20 minutes without having to stop and walk around. I had to give up my job as a warehouse supervisor because I could not be on my feet for the required hours.

Examiner listens for: Specific functional restrictions, impact on employment, impact on activities of daily living, need for assistance from others, adaptive behaviors (avoiding stairs, using grab bars, sleeping in recliner instead of bed).

Avoid: Generic statements like 'my back hurts' without specific functional examples. The DBQ has a specific field asking for functional loss description - ensure the examiner captures concrete examples.

Radiculopathy and Nerve Symptoms

How to describe it: Describe radiating symptoms precisely by location, character, and laterality. Distinguish between your dominant and non-dominant sides. Report any bowel or bladder changes, as these can indicate more severe nerve involvement.

Example: I have constant electric, shooting pain that runs from my lower back down through my right buttock, down the back of my thigh, and into my right calf and the outside of my foot. On my left side, I have intermittent numbness and tingling from my hip to my big toe. My right foot sometimes feels like it's asleep. I have noticed significant weakness when trying to stand on my tiptoes on the right side.

Examiner listens for: Dermatomal distribution matching specific nerve roots (L2-L5, S1-S3), severity (mild/moderate/severe), bilaterality, motor involvement (weakness, foot drop), sensory changes (numbness, paresthesia), and reflex changes.

Avoid: Describing only back pain and failing to detail the leg symptoms. Radiculopathy is rated separately from the spine condition and can significantly increase your combined rating.

DeLuca Factors - Repetitive Use and Fatigue

How to describe it: Describe how your symptoms change with repeated or sustained activity - specifically how your range of motion decreases after activity, how pain intensifies, and how long recovery takes.

Example: When I first get up in the morning, I can bend forward maybe 10-15 inches toward the floor. After walking to the mailbox and back, my back tightens so severely I can barely bend forward at all and must lie down. After 30 minutes of any light activity, I need at least 1-2 hours of rest before I can move comfortably again. Even at my desk, after 20 minutes of sitting, my pain increases from a 4 to a 7 and my legs go numb.

Examiner listens for: Whether range of motion and pain worsen with repetitive use, how quickly fatigue and pain develop, recovery time needed between activities - all required under DeLuca v. Brown for accurate functional assessment.

Avoid: Only reporting your initial ROM at the start of the exam without mentioning that it deteriorates rapidly with activity.
