What to Expect During Your Exam

Exam Overview

To evaluate the current severity of thoracolumbar spinal stenosis for VA disability rating purposes, document range of motion, neurological involvement, functional loss, and establish or confirm nexus to military service

What the examiner evaluates:

  • Current diagnosis and ICD code for spinal stenosis
  • Active and passive range of motion in all planes
  • Pain behavior during motion and at rest
  • Neurological signs including radiculopathy (sciatic and femoral nerve involvement)
  • Reflex testing of bilateral lower extremities
  • Sensory testing including dermatomal distribution
  • Muscle strength grading
  • Muscle atrophy measurement
  • Functional loss due to pain, weakness, fatigability, incoordination, or lack of endurance
  • Effect of repetitive use on range of motion
  • Flare-up frequency, severity, and duration
  • Assistive device use
  • Incapacitating episodes
  • Impact on occupational and daily activities

Exam is conducted in person with a physician or PA. You may be asked to perform movements in a standing (weight-bearing) and lying or seated (non-weight-bearing) position. The examiner may use a goniometer to measure degrees of motion. Wear comfortable, loose-fitting clothing that allows access to your lower back and legs. You have the right to request that the examination be recorded in most states.

Typical duration: 30-45 minutes

Forward Flexion (Active)

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.

Key thresholds:

  • Greater than 60 degrees — Supports 10% rating combined with DeLuca factors
  • 30 to 60 degrees — Supports 20% rating
  • Less than 30 degrees — Supports 40% rating
  • Unfavorable ankylosis of entire thoracolumbar spine — Supports 50% or 100% depending on position

Tips:

  • Stop at the point where pain genuinely prevents further movement - do not push through severe pain to appear compliant
  • Tell the examiner exactly when and where pain begins during the movement
  • Do not pre-stretch or warm up before the exam, as this can temporarily increase your range beyond your typical daily range
  • Your 'worst day' range of motion is what limits your function, mention this if today is a better day than usual

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)

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.

Key thresholds:

  • 0 to 30 degrees — Normal range; any reduction with pain is documented under DeLuca
  • Significantly restricted — Contributes to combined functional loss picture

Tips:

  • Report any pain, tightening, or nerve symptoms that occur during extension
  • Extension often triggers neurogenic claudication symptoms in spinal stenosis - describe these clearly if they occur

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)

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.

Key thresholds:

  • Restriction below 30 degrees with pain — Documented under DeLuca as additional functional loss

Tips:

  • Report any asymmetry - if one side is more painful or restricted, say so clearly
  • Side-to-side differences can indicate nerve root compression

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

Right and Left Lateral Rotation (Active)

Degrees of torso rotation; normal is 0-30 degrees each side

What to expect:

Usually tested seated to isolate thoracolumbar motion.

Key thresholds:

  • Restriction with pain — Contributes to overall functional limitation documentation

Tips:

  • Report any shooting or burning pain that occurs with rotation

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

Passive Range of Motion

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.

Key thresholds:

  • Passive greater than active — Indicates pain is limiting active motion - important DeLuca documentation
  • Passive equals active — Indicates structural or combined limitation

Tips:

  • Passive ROM testing is required under Correia v. McDonald - if not performed, it should be noted
  • This test helps confirm the role of pain in limiting your motion

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

Repetitive Use Testing (3 Repetitions)

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.

Key thresholds:

  • ROM decreases after repetition — Supports additional functional loss rating under DeLuca - examiner must document this
  • Increased pain with repetition without ROM decrease — Still documentable under DeLuca as functional loss

Tips:

  • Do not pace yourself to maintain the same ROM across repetitions - move as you naturally would
  • Tell the examiner if you feel more pain, fatigue, or weakness after the second or third repetition
  • This directly supports a higher effective rating

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)

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.

Key thresholds:

  • Positive SLR with radicular pain below knee — Supports sciatic nerve involvement and radiculopathy rating under 8520/8521
  • Positive femoral stretch test — Supports femoral nerve (L2-L4) involvement

Tips:

  • Report exactly where pain radiates - e.g., 'pain shoots from my low back down through my buttock and into my right calf and foot'
  • Distinguish between back pain alone (not a positive SLR) and leg pain reproducing your symptoms (positive SLR)

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

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.

Key thresholds:

  • Reduced or absent reflexes — Objective evidence of nerve root compromise - supports radiculopathy rating
  • Normal reflexes — Does not rule out radiculopathy; symptoms are still valid

Tips:

  • Reflex testing is objective - relax your muscles completely for accurate results
  • Absent or asymmetric reflexes strengthen your radiculopathy claim

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

Sensory Testing (Dermatomal)

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.

Key thresholds:

  • Decreased sensation in dermatomal pattern — Objective evidence supporting specific nerve root involvement and radiculopathy
  • Bilateral sensory changes — May support bilateral radiculopathy claims

Tips:

  • Report any areas of numbness, tingling, or burning that you experience daily - these may not be present at every moment of the exam
  • Describe the distribution accurately: e.g., 'numbness on the top of my foot and big toe' (L4-L5) or 'numbness on the outside of my foot and little toe' (S1)

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)

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.

Key thresholds:

  • Grade 4 of 5 (slight weakness) — Supports mild radiculopathy
  • Grade 3 of 5 (movement against gravity only) — Supports moderate radiculopathy
  • Grade 2 or below — Supports severe radiculopathy or paralysis

Tips:

  • Perform strength testing honestly - do not exaggerate weakness or hold back strength artificially
  • Report any functional weakness you notice in daily activities: foot drop, difficulty climbing stairs, inability to stand on toes or heels

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

Muscle Atrophy Measurement

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.

Key thresholds:

  • Difference greater than 1 cm in calf — Objective evidence of neurogenic atrophy supporting moderate-severe radiculopathy
  • Difference greater than 2 cm in thigh — Significant atrophy supporting higher radiculopathy rating

Tips:

  • If you have noticed one leg appears thinner than the other, mention this to the examiner
  • Atrophy from chronic disuse due to pain is also ratable - mention if you favor one leg

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

Estimate

Rating Criteria Breakdown

100% Unfavorable ankylosis of the entire spine (both thoracolumba ...

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.

Key Symptoms

  • Complete loss of spinal mobility across all segments
  • Fused in unfavorable position - entire spine affected
  • Total dependence on assistive devices
  • Inability to perform most activities of daily living independently

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.

50% Unfavorable ankylosis of the entire thoracolumbar spine (fus ...

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

Key Symptoms

  • Spine fused in a flexed or otherwise unfavorable position
  • Inability to straighten the back
  • Severe daily functional impairment
  • Inability to perform basic self-care without assistance
  • Severe gait disturbance

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.

40% Forward flexion of the thoracolumbar spine to 30 degrees or ...

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

Key Symptoms

  • Severe restriction of forward flexion (0-30 degrees)
  • Inability to bend forward to tie shoes or pick up objects from floor
  • Favorably ankylosed thoracolumbar spine
  • Constant pain limiting all physical activity
  • Significant neurogenic claudication with inability to walk more than short distances
  • Dependence on assistive devices for ambulation

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.

20% Forward flexion of the thoracolumbar spine greater than 30 d ...

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.

Key Symptoms

  • Moderate restriction of forward flexion (31-60 degrees)
  • Combined ROM 120 degrees or less
  • Antalgic gait or posture
  • Visible muscle spasm causing altered spinal contour
  • Pain that begins early in range of motion
  • Significant stiffness lasting hours after rest
  • Neurogenic claudication - leg pain with walking that resolves with sitting or leaning forward

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.

10% Forward flexion of the thoracolumbar spine greater than 60 d ...

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.

Key Symptoms

  • Mild restriction of forward flexion (61-85 degrees)
  • Localized tenderness on palpation
  • Muscle guarding or spasm without gait disturbance
  • Pain with motion that begins before end of range
  • Mild stiffness after prolonged sitting or standing

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.

How to Describe Your Symptoms

Pain Quality and Location

How to describe:

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.

Worst-day 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.”

What the 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.

Understatements to 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:

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.

Worst-day 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.”

What the examiner listens for:

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

Understatements to 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:

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.

Worst-day 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.”

What the 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.

Understatements to 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:

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.

Worst-day 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.”

What the 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).

Understatements to 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:

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.

Worst-day 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.”

What the 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.

Understatements to 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:

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.

Worst-day 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.”

What the 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.

Understatements to avoid:

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

Your Rights During a C&P Exam

  • You have the right to be examined in person by a qualified healthcare provider - a physician (MD or DO) or physician assistant (PA). Nurse practitioners are generally not qualified examiners for C&P exams.
  • You have the right to request that the C&P examination be recorded (audio or video) in most states that permit one-party consent recording. Inform the examiner before the exam begins.
  • You have the right to review and obtain a copy of the completed DBQ after the examination. Request this through your VSO, accredited claims agent, or attorney.
  • You have the right to request a new C&P examination if the original exam was inadequate, incomplete, or performed by an unqualified examiner. Grounds include: failure to examine you in person, failure to complete required DBQ sections (e.g., radiculopathy section left blank), failure to document DeLuca factors, or exam lasting only a few minutes without physical testing.
  • You have the right to submit a lay statement (VA Form 21-4138) or a personal statement correcting inaccuracies in the exam report or supplementing information not captured during the exam.
  • You have the right to be treated with dignity and respect during the examination. If the examiner is dismissive, rude, or appears to be rushing, you may note this in your post-exam documentation.
  • You have the right to bring a VSO representative, accredited claims agent, or attorney to the examination - however, they may not answer questions on your behalf or interfere with the medical examination process.
  • You have the right to submit independent medical opinions (IMOs) or independent medical examinations (IMEs) from private physicians as counter-evidence if you disagree with the C&P examiner's findings.
  • Under the PACT Act and AMA review process, you have the right to request a Higher-Level Review or supplemental claim if you believe the rating does not accurately reflect the severity documented in the DBQ.
  • The examiner is required to consider your condition on its worst days, not just the day of the exam, per M21-1 adjudication guidance and DeLuca v. Brown case law.
