What to Expect During Your Exam

Exam Overview

To document the current severity of median nerve neuritis for VA disability rating purposes under 38 CFR 4.124a, DC 8615. The examiner will assess the degree of incomplete paralysis (mild, moderate, moderately severe, or severe) and whether the condition is characterized by organic changes, which affects the maximum allowable rating.

What the examiner evaluates:

  • Sensory deficits in the median nerve distribution (palmar surface of thumb, index, middle, and lateral half of ring finger; dorsal tips of same digits)
  • Motor deficits including thenar muscle weakness, opposition of thumb, abduction of thumb, and flexion of fingers
  • Muscle atrophy of thenar eminence
  • Grip strength and pinch strength bilaterally
  • Tinel's sign at the wrist or forearm
  • Phalen's sign (wrist flexion test)
  • Deep tendon reflexes (biceps, brachioradialis)
  • Presence or absence of organic changes (muscle atrophy, trophic changes, vasomotor changes)
  • Functional impact on activities of daily living and occupational function
  • Assistive device use
  • Electromyography (EMG) and nerve conduction study results if available
  • Whether the condition is purely sensory or also involves motor deficits
  • Bilateral comparison of affected versus unaffected extremity

Exam will be conducted in person at a VA or contracted clinic. You have the right to request a same-sex examiner. In most states you have the right to record the examination. The examiner will review your claims file prior to or during the exam. Arrive wearing clothing that allows easy access to your forearms and hands. Bring all assistive devices you use (wrist splints, braces). Do not take pain medications that would artificially suppress symptoms on exam day unless medically necessary.

Typical duration: 30-45 minutes

Grip Strength Testing (Bilateral)

Motor function of the median nerve, specifically the extrinsic flexors of the hand. Reduced grip strength on the affected side compared to the contralateral side indicates motor involvement of the median nerve.

What to expect:

Examiner will ask you to squeeze a dynamometer or the examiner's fingers as hard as possible, typically three times. Both hands will be tested. Results are compared bilaterally. The examiner documents whether grip is normal, mildly reduced, moderately reduced, or severely reduced.

Key thresholds:

  • Normal bilateral grip — Supports mild or sensory-only rating; maximum rating without organic changes is moderate incomplete paralysis
  • Mildly reduced grip on affected side — Supports mild to moderate incomplete paralysis rating
  • Moderately reduced grip — Supports moderate to moderately severe incomplete paralysis rating
  • Severely reduced grip with thenar atrophy — Supports severe incomplete paralysis rating; organic change present elevates maximum allowable rating for neuritis

Tips:

  • Do not take muscle relaxants or pain medications before the exam that would artificially improve your grip.
  • Perform the test as you would on a typical or bad day - do not push through pain to demonstrate strength you do not actually have.
  • If grip is worse after repetitive use, tell the examiner - this is a DeLuca factor.
  • Report if grip strength worsens after sustained activity or by end of day.

Pain considerations: If squeezing causes significant pain in the palm, thumb base, or fingers, verbalize this to the examiner during the test. Pain during grip testing is relevant to functional loss beyond the measured strength value.

Pinch Strength Testing (Lateral and Opposition Pinch)

Thenar muscle function innervated by the median nerve, specifically the abductor pollicis brevis, flexor pollicis brevis, and opponens pollicis. Opposition pinch (tip of thumb to tip of index finger) is a classic median nerve function test.

What to expect:

Examiner will ask you to pinch between thumb and index finger, or hold a small object between the tips of thumb and fingers. Both sides will be compared. Weakness or inability to perform opposition is a strong indicator of median nerve motor involvement.

Key thresholds:

  • Normal pinch bilaterally — Sensory-only picture; moderate maximum without organic changes
  • Weak opposition pinch on affected side — Motor involvement; supports moderate to moderately severe rating
  • Inability to oppose thumb to fingers — Significant motor deficit; supports severe incomplete paralysis with organic change documentation

Tips:

  • Demonstrate accurately - if you cannot make an 'OK' sign due to weakness, show the examiner your actual ability.
  • Describe the impact on daily tasks such as buttoning shirts, picking up coins, turning keys, or writing.
  • If pinch strength has worsened over time, mention that progression.

Pain considerations: Pinching may provoke pain at the thenar eminence or radiate into the fingers. Tell the examiner if the pinch itself causes pain, not just weakness.

Tinel's Sign at the Wrist/Forearm

Nerve irritability and the presence of neuritis or nerve compression along the median nerve course. A positive Tinel's sign (tingling or electric sensation shooting into the median nerve distribution when the nerve is tapped) supports the diagnosis of median nerve pathology.

What to expect:

The examiner will lightly tap over the carpal tunnel at the wrist or along the forearm. A positive result produces tingling, electric shock, or paresthesias shooting into the thumb, index finger, middle finger, and/or lateral ring finger.

Key thresholds:

  • Positive Tinel's at wrist — Supports median nerve neuritis diagnosis and documents the anatomical location of pathology
  • Negative Tinel's — Does not rule out neuritis - document if you have had prior positive results in your treatment records

Tips:

  • Tell the examiner exactly where you feel tingling when tapped - which specific fingers.
  • If symptoms radiate up the forearm as well as down into the hand, describe both directions.
  • Note whether the sensation lingers after tapping or is immediate and transient.

Pain considerations: If the tapping is painful rather than just producing tingling, clearly state 'that is painful' so the examiner records pain rather than only paresthesias.

Phalen's Sign (Wrist Flexion Test)

Reproduction of median nerve symptoms (numbness, tingling, pain) with sustained wrist flexion. A positive Phalen's sign indicates median nerve compromise at or near the carpal tunnel.

What to expect:

Examiner will ask you to hold your wrists in a flexed position (backs of hands touching, fingers pointing downward) for up to 60 seconds. Positive if tingling or numbness develops in the median nerve distribution within 60 seconds.

Key thresholds:

  • Positive within 30 seconds — Strong indicator of significant median nerve involvement
  • Positive between 30-60 seconds — Moderate indicator of median nerve involvement
  • Negative — Does not exclude neuritis - other mechanisms of median nerve involvement exist beyond the carpal tunnel

Tips:

  • Report exactly when symptoms begin during the test (e.g., 'tingling started at about 15 seconds').
  • Describe which fingers the tingling affects.
  • If you cannot maintain the position for 60 seconds due to pain or weakness, tell the examiner why you stopped.

Pain considerations: If wrist flexion itself is painful (not just producing tingling), state this. Pain reproduced by wrist flexion is separately relevant.

Sensory Testing (Light Touch and Pinprick)

The integrity of sensory fibers in the median nerve. Tests whether diminished, absent, or altered sensation is present over the palmar surface of the thumb, index finger, middle finger, and lateral half of the ring finger, as well as the dorsal tips of those digits.

What to expect:

Examiner will touch or prick the skin in various areas of your hand and fingers, asking you to compare sensation on the affected hand to the unaffected hand or to a reference area. You may be asked to close your eyes and report where and when you feel the stimulus.

Key thresholds:

  • Reduced but present sensation in median nerve territory — Supports mild to moderate sensory involvement; sensory-only nerve disability is rated mild or at most moderate per M21-1
  • Complete loss of sensation in median nerve territory — Organic change; may support higher rating levels for neuritis
  • Allodynia or hyperalgesia (painful response to light touch) — Supports neuritis diagnosis with significant pain component; document location and severity

Tips:

  • Be honest about what you do and do not feel. Do not exaggerate or minimize.
  • If sensation is reduced rather than absent, describe the quality: 'It feels like I am touching through a thick glove.'
  • Report areas of burning, electric, or abnormal sensations even if the examiner does not specifically ask.
  • Describe whether numbness is constant, intermittent, or worsened by specific activities.

Pain considerations: Allodynia (pain from light touch) should be explicitly stated. Do not tolerate painful stimuli silently - verbalize your experience.

Thenar Muscle Atrophy Assessment

The presence of organic change due to median nerve denervation. Thenar muscle wasting (visible or measurable atrophy at the base of the thumb on the palm) is a key organic change that raises the maximum allowable rating for neuritis.

What to expect:

Examiner will visually inspect and may measure circumference of both hands/forearms to compare muscle bulk. Thenar atrophy may also be detected by palpation. The examiner documents location and estimated degree of atrophy.

Key thresholds:

  • No atrophy present — Maximum rating for neuritis without organic changes is generally moderate incomplete paralysis
  • Mild thenar atrophy present — Organic change documented; maximum rating for neuritis elevates toward severe incomplete paralysis
  • Marked thenar atrophy — Significant organic change; supports higher end of rating spectrum for neuritis per 38 CFR 4.124a

Tips:

  • Point out any visible flattening or hollowing at the base of your thumb on the palm side.
  • If your treating physician has documented atrophy in private records, bring those records to the exam.
  • Describe how your thenar area looks compared to how it used to look or compared to your other hand.

Pain considerations: Atrophy itself is not painful but may be associated with weakness and functional loss. Connect the atrophy to specific functional limitations you experience.

Estimate

Rating Criteria Breakdown

50% Severe incomplete paralysis of the median nerve. This is the ...

Severe incomplete paralysis of the median nerve. This is the maximum rating for neuritis WITH organic changes under DC 8615. Represents near-complete functional loss of median nerve function with substantial permanent organic changes. The hand is profoundly limited in all fine motor and grip activities. Organic changes are marked and documented. This is the ceiling for neuritis under DC 8615 per 38 CFR 4.124a and M21-1 V.iii.12.A.2.b.

Key Symptoms

  • Marked thenar muscle atrophy with visible flattening of the thenar eminence
  • Severely reduced or absent grip and pinch strength
  • Near-complete loss of thumb opposition function
  • Constant, severe, unrelenting pain or burning throughout median nerve territory
  • Dense sensory loss (significantly reduced or absent light touch, pinprick) over most of median nerve distribution
  • Significant trophic changes: ulcerations, severe skin atrophy, nail dystrophy
  • Inability to perform most fine motor tasks independently
  • Functional limitation approaching that of an amputated digit or hand

CFR: Severe incomplete paralysis is the maximum allowable evaluation for neuritis under DC 8615 when organic changes are present. This represents substantially less impairment than complete paralysis of the median nerve but reflects the most severe manifestation of neuritis with demonstrable nerve damage.

30% Moderately severe incomplete paralysis of the median nerve. ...

Moderately severe incomplete paralysis of the median nerve. This level requires the presence of organic changes (thenar atrophy, trophic skin changes, vasomotor changes) or significant combined sensory and motor deficits. For neuritis WITH organic changes, the maximum allowable rating is severe incomplete paralysis, so moderately severe represents a significant intermediate level. Functional use of the hand is substantially impaired.

Key Symptoms

  • Thenar muscle atrophy visible or measurable on physical examination
  • Significant weakness of thumb opposition and abduction
  • Substantially reduced grip and pinch strength (more than mild reduction)
  • Constant pain, burning, or electric sensations throughout median nerve territory
  • Trophic skin changes: dry skin, cracking, hair loss, nail changes in median nerve distribution
  • Significant functional loss: difficulty holding objects, inability to perform fine motor tasks independently
  • Vasomotor changes: skin color changes, temperature differences in affected fingers

CFR: When organic changes (thenar atrophy, trophic changes) are present, the maximum for neuritis under DC 8615 is severe incomplete paralysis. Moderately severe reflects marked functional loss of the hand with documented organic evidence of nerve damage.

20% Moderate incomplete paralysis of the median nerve. This is t ...

Moderate incomplete paralysis of the median nerve. This is the maximum rating achievable for neuritis WITHOUT organic changes (such as muscle atrophy, trophic changes, or vasomotor changes). Per M21-1, the moderate level is reserved for the most significant and disabling cases of sensory-only involvement, or for cases where some motor involvement is present but not accompanied by organic changes. Symptoms are more constant, affect a broader area, and produce meaningful functional limitation.

Key Symptoms

  • Persistent or near-constant numbness, tingling, or burning pain throughout median nerve distribution
  • Significant reduction in grip or pinch strength on the affected side
  • Difficulty with fine motor tasks: buttoning, writing, picking up small objects, typing
  • Sensory loss that is continuous rather than intermittent
  • Sleep disruption due to nocturnal paresthesias
  • Provokable symptoms with sustained activity that do not fully resolve with rest
  • No measurable muscle atrophy or trophic changes (organic changes absent)

CFR: Moderate incomplete paralysis represents the ceiling for neuritis without organic changes per M21-1 V.iii.12.A.2.b. Pain described as dull, burning, or aching throughout the median nerve territory with functional limitations on grip and fine motor tasks.

10% Mild incomplete paralysis of the median nerve. Under DC 8615 ...

Mild incomplete paralysis of the median nerve. Under DC 8615 for neuritis, this applies when symptoms are sensory in nature, recurrent but not continuous, reflecting a lower degree of nerve impairment. Per M21-1 guidance, purely sensory peripheral nerve disabilities are rated mild or at most moderate. The mild level is appropriate when sensory symptoms are intermittent and/or affect a smaller portion of the median nerve distribution.

Key Symptoms

  • Intermittent numbness or tingling in some or all of the median nerve distribution (thumb, index, middle finger, lateral ring finger)
  • Occasional pain described as dull, intermittent, or aching in the median nerve distribution
  • Symptoms may be provoked by activity or sustained postures but resolve with rest
  • Minimal or no functional limitation during most activities
  • Grip and pinch strength essentially normal or only minimally affected

CFR: Mild incomplete paralysis under DC 8515 (median nerve) - neuritis rated by analogy to incomplete paralysis levels; mild represents substantially less impairment than the full description for that nerve's paralysis.

How to Describe Your Symptoms

Pain Character and Distribution

How to describe:

Describe the quality (burning, electric, aching, stabbing, dull), location (specify which fingers and areas of the hand or forearm), frequency (constant vs. intermittent), severity (0-10 scale on a bad day), and what makes it better or worse. Median nerve pain typically affects the palm and the thumb, index, middle, and lateral ring finger.

Worst-day example:

“On my worst days, I have a constant burning and electric pain that runs from my wrist through my palm and into my thumb, index, and middle fingers. It rates an 8 out of 10. Holding anything - even a glass of water - makes it worse. The pain wakes me up at night and I have to shake my hand out for 10 to 15 minutes before it settles down.”

What the examiner listens for:

Specificity of distribution matching the median nerve territory, quality descriptors consistent with neuropathic pain, frequency and duration patterns, nocturnal worsening (classic for median nerve neuritis), and functional impact.

Understatements to avoid:

Do not say 'it is not that bad' or 'I manage okay.' Do not minimize nocturnal symptoms. Do not describe only your average day - describe your worst typical day.

Sensory Loss and Paresthesias

How to describe:

Specify which fingers and areas are numb or tingly, whether it is constant or comes and goes, what triggers it (typing, gripping, holding a steering wheel, sleeping), and how long episodes last. Distinguish between numbness (reduced sensation) and tingling/burning (active sensory disturbance).

Worst-day example:

“My thumb, index finger, and middle finger on the right hand are numb almost constantly. On bad days the numbness extends into my palm. I cannot tell the difference between hot and cold in those fingers, and I have burned myself several times because I did not feel the heat. The tingling is like pins and needles that never fully goes away.”

What the examiner listens for:

Consistency of the distribution with the median nerve (not extending to the little finger, which would suggest ulnar nerve involvement), whether symptoms are constant or provoked, and safety concerns such as burns or cuts due to sensory loss.

Understatements to avoid:

Do not say 'just a little numbness.' Numbness that causes safety hazards (burns, cuts, dropped objects) is significant and should be stated explicitly.

Motor Weakness and Functional Loss

How to describe:

Describe specific tasks you can no longer perform or perform with difficulty due to weakness in your hand. Focus on grip strength, pinch strength, and thumb opposition. Quantify if possible (e.g., 'I can only hold a pen for 5 minutes before my hand gives out').

Worst-day example:

“I can barely pick up a coin off a flat surface because my thumb and index finger do not have the strength to pinch. I drop objects multiple times per day. I cannot button my shirt with my dominant hand and I have had to switch to Velcro clothing. Typing for more than 10 minutes causes my grip to give out entirely.”

What the examiner listens for:

Specific functional limitations (buttoning, typing, writing, opening jars, turning keys), frequency of dropping objects, any adaptive behaviors, and whether weakness worsens with use (DeLuca factor for repetitive use).

Understatements to avoid:

Do not demonstrate maximum effort grip during the exam if that effort causes significant pain or if you could not sustain it. Do not say 'I can still do most things' if you have made significant adaptations to your daily routine.

Muscle Atrophy and Organic Changes

How to describe:

Point out any visible wasting at the base of your thumb (thenar eminence). Describe changes in your skin in the affected fingers (dryness, cracking, nail changes). Compare your affected hand to your unaffected hand visually for the examiner.

Worst-day example:

“The muscle at the base of my right thumb is noticeably smaller and flatter than my left. My right thumb side of my palm looks hollow compared to the other hand. My index and middle fingers have very dry, cracked skin that does not seem to heal normally. My nails on those fingers have become ridged and brittle.”

What the examiner listens for:

Objective evidence of organic changes that raise the maximum allowable rating for neuritis: thenar atrophy, trophic skin changes, vasomotor changes. These are critical because they unlock the higher rating tiers for DC 8615.

Understatements to avoid:

Do not assume the examiner will notice subtle atrophy. Actively point to it and describe when you first noticed the change.

Flare-Ups and Repetitive Use Worsening

How to describe:

Describe what triggers worsening of your symptoms (e.g., sustained gripping, typing, vibration, cold weather), how long flare-ups last, how frequently they occur, and what level of activity triggers them. This directly satisfies DeLuca factors for neurological conditions.

Worst-day example:

“After typing for more than 15 minutes my entire hand goes numb and the burning pain increases from a 3 to an 8. I then cannot use my hand effectively for the next 2 to 3 hours. Cold weather makes my fingers numb and useless within minutes. I have three to four severe flare-ups per week that force me to stop all hand activity.”

What the examiner listens for:

Threshold of activity that triggers symptom worsening, duration of flare-ups, frequency, impact on ability to work or perform sustained tasks, and correlation with occupational or daily activities.

Understatements to avoid:

Do not describe your symptoms only at rest. If your condition is worsened by use - which is the nature of neuritis - you must describe that worsening pattern explicitly.

Impact on Work and Daily Life

How to describe:

Describe specifically how median nerve neuritis affects your occupational functioning, hobbies, self-care, and relationships. Quantify time lost from work or required accommodations. Describe any modifications you have made to perform daily tasks.

Worst-day example:

“I had to stop working as a [occupation] because I can no longer grip tools for more than a few minutes. I have lost income and had to transfer to a lighter duty position. At home, I cannot open jars, type emails, or write checks. My wife helps me with buttons and small tasks. I have given up guitar playing, which I had done for 30 years.”

What the examiner listens for:

The examiner is required to document the impact of the peripheral nerve condition on occupational function. Specific, concrete examples are far more useful than general statements.

Understatements to avoid:

Do not say 'I manage.' Describe what managing actually costs you - the adaptations, the pain, the lost activities, the help you require from others.

Your Rights During a C&P Exam

  • You have the right to record your C&P examination in most states. Check your state's consent law. One-party consent states allow recording without notifying the examiner; two-party consent states require notification. Notify the examiner if required by your state.
  • You have the right to request a same-sex examiner. Submit this request in writing to the VA in advance of scheduling.
  • You have the right to have a VSO representative or accredited claims agent attend your exam as an observer in some circumstances. Contact your VSO for current VA policy.
  • You have the right to review and receive a copy of your completed DBQ. The examiner or VA regional office must provide it upon request.
  • You have the right to submit additional evidence rebutting an inadequate or inaccurate C&P examination, including private independent medical opinions (IMOs).
  • You have the right to request a new C&P examination if your original exam was inadequate, meaning it did not consider all relevant conditions, was conducted by an unqualified examiner, or relied on an inaccurate factual premise. File a Notice of Disagreement or request via your VSO.
  • You have the right to a duty to assist from VA. If relevant records have not been obtained and are reasonably available, VA is required to assist in obtaining them before adjudicating your claim.
  • You have the right to a favorable interpretation of the evidence when there is an approximate balance of positive and negative evidence (benefit of the doubt standard, 38 CFR 3.102).
  • You are not required to prove your disability with certainty - the legal standard is at least as likely as not (50% or greater probability) for service connection, and your current symptoms should be reported accurately and completely for proper rating.
  • You have the right to have your exam conducted in person rather than solely by records review, particularly for complex conditions involving neurological examination findings.
