What to Expect During Your Exam

Exam Overview

To evaluate the nature and severity of median nerve neuralgia for VA disability rating purposes under 38 CFR 4.124a, DC 8715. The examiner will assess the degree of pain, sensory loss, motor deficits, and functional impairment attributable to median nerve pathology in order to assign an appropriate level of incomplete paralysis, neuritis, or neuralgia.

What the examiner evaluates:

  • Pain characteristics: location, quality (burning, shooting, aching, intermittent vs. constant), and distribution along the median nerve territory (palmar aspect of thumb, index, middle, and lateral half of ring finger; thenar eminence)
  • Sensory deficits: numbness, tingling, hypoesthesia, allodynia, or paresthesias in the median nerve distribution
  • Motor function: strength of thenar muscles (abductor pollicis brevis, opponens pollicis, flexor pollicis brevis), grip strength, pinch strength, and fine motor coordination
  • Special provocative tests: Tinel's sign at the carpal tunnel (wrist percussion), Phalen's test (sustained wrist flexion), and Durkan's compression test
  • Reflex testing: brachioradialis reflex may be assessed for baseline comparison
  • Muscle atrophy: thenar eminence wasting indicating chronic denervation
  • Functional loss: impact on activities of daily living, occupation, and repetitive use tasks
  • Assistive devices used (wrist splints, braces, adaptive tools)
  • Results of electrodiagnostic studies (EMG/nerve conduction velocity) if available
  • Gait assessment if bilateral or systemic neuropathy is a concern
  • Review of service treatment records, post-service medical records, and any prior C&P exam findings

The exam will typically begin with a structured interview about symptom history, onset, and functional impact, followed by a hands-on physical examination of the upper extremities. The examiner will compare the affected side to the unaffected side. Bring all current medications, assistive devices (wrist splints, braces), and any electrodiagnostic reports. The exam is conducted in person unless otherwise specified. You have the right to request that the exam be recorded in most states.

Typical duration: 30-45 minutes

Tinel's Sign (Wrist/Carpal Tunnel)

Nerve irritability and regeneration at the carpal tunnel. A positive test (tingling or electric sensation radiating into the median nerve distribution upon light percussion over the carpal tunnel at the wrist) suggests median nerve pathology.

What to expect:

The examiner will tap or lightly percuss the volar surface of your wrist over the carpal tunnel with a finger or reflex hammer. Tell the examiner immediately if you feel any tingling, electric shock sensation, or pain radiating into your fingers.

Key thresholds:

  • Positive (tingling into median nerve territory) — Supports objective evidence of median nerve dysfunction; documented in DBQ fields RG_9_TINELS_RIGHT or RG_9_TINELS_LEFT
  • Negative — Does not rule out neuralgia; subjective symptoms remain evaluable

Tips:

  • Report any tingling, shooting pain, or electric sensation immediately when it occurs, no matter how brief
  • Tell the examiner which fingers or areas of the hand are affected by the sensation
  • Do not minimize or wait to see if it gets worse - report the sensation as soon as it starts

Pain considerations: Even a mild tingling counts as a positive sign. Report the sensation accurately and describe whether it matches your usual symptoms.

Phalen's Test (Wrist Flexion Test)

Carpal tunnel compression of the median nerve. The examiner holds your wrists in maximum flexion for up to 60 seconds to see if your symptoms are reproduced (numbness, tingling, or pain in the median nerve distribution).

What to expect:

You will be asked to press the backs of your hands together (or the examiner will passively flex your wrists) and hold that position for up to 60 seconds. Report any tingling, numbness, burning, or pain that develops in your thumb, index finger, middle finger, or lateral half of your ring finger.

Key thresholds:

  • Positive within 60 seconds — Strong objective support for median nerve compression/neuralgia; documented in DBQ fields RG_9_PHALENS_RIGHT or RG_9_PHALENS_LEFT
  • Positive within 30 seconds — Suggests more significant compression; report timing to the examiner
  • Negative at 60 seconds — Does not eliminate neuralgia; subjective pain history remains a valid basis for evaluation

Tips:

  • Tell the examiner exactly when symptoms begin (e.g., 'I felt tingling at about 20 seconds')
  • Describe which specific fingers are affected
  • If wrist flexion itself causes pain before symptoms appear, report that pain as well
  • Note if this position reproduces your typical nighttime or activity-related symptoms

Pain considerations: If holding this position is painful due to wrist arthritis or other conditions, tell the examiner. Pain from the wrist position itself is also relevant functional information.

Grip Strength Testing

Overall hand grip strength, which is significantly dependent on median nerve motor function (particularly thenar muscles). Weakness indicates motor involvement beyond pure neuralgia.

What to expect:

You may be asked to squeeze a dynamometer or the examiner's fingers as hard as you can. The examiner will typically test both hands for comparison. Grip strength is documented in DBQ fields RG_4A_GRIP_RIGHT and RG_4A_GRIP_LEFT.

Key thresholds:

  • Reduced compared to contralateral side — Supports functional motor impairment consistent with median nerve involvement; important for distinguishing neuralgia from incomplete paralysis
  • Normal bilaterally — Consistent with pure sensory neuralgia; rating ceiling may be moderate incomplete paralysis level per 38 CFR 4.124

Tips:

  • Perform the test as you would on a typical or bad day - do not push through pain to appear stronger
  • If gripping causes pain, tell the examiner before you perform the test
  • Inform the examiner if your grip strength varies throughout the day or worsens with use

Pain considerations: Under DeLuca v. Brown principles, if pain limits your grip before you reach maximum mechanical strength, that pain-limited grip is your true functional grip. Tell the examiner: 'I stopped squeezing because of pain, not because I had no more strength.'

Pinch Strength Testing

Lateral and tip pinch strength, highly dependent on thenar muscles innervated by the median nerve. Documented in DBQ fields RG_4A_PINCH_RIGHT and RG_4A_PINCH_LEFT.

What to expect:

The examiner will ask you to pinch their finger or a pinch gauge between your thumb and index/middle finger. Both hands will typically be tested for comparison.

Key thresholds:

  • Reduced pinch strength on affected side — Objective evidence of median nerve motor involvement; supports higher severity rating
  • Inability to form adequate pinch (ape hand deformity) — Consistent with severe or complete median nerve dysfunction

Tips:

  • If the pinching motion causes burning or shock-like pain, describe it specifically
  • Note if you drop objects or have difficulty with fine motor tasks like buttoning or writing
  • Mention any compensation strategies you use (e.g., using your other hand, avoiding certain grips)

Pain considerations: Pain during pinching that prevents full effort is a legitimate functional limitation. Report it as it occurs and describe the quality of the pain (burning, sharp, electric).

Thenar Muscle Atrophy Assessment

Visual and palpable wasting of the thenar eminence (the muscle pad at the base of the thumb), indicating chronic denervation by the median nerve. Documented in DBQ fields for muscle atrophy location and limb measurements.

What to expect:

The examiner will visually inspect and may measure the thenar eminence on both hands for comparison. They may also measure forearm circumference at standard distances from anatomical landmarks and record measurements in the DBQ (fields for normal side and atrophied side measurements).

Key thresholds:

  • Visible or measurable atrophy of thenar eminence — Objective evidence of chronic or severe median nerve involvement; supports higher rating level
  • No atrophy present — Consistent with sensory-predominant neuralgia; does not preclude a neuralgia rating

Tips:

  • If you have noticed muscle wasting in your thumb area, point it out to the examiner
  • Note any difficulty performing tasks requiring thenar strength (opening jars, turning keys, writing)
  • If atrophy is subtle, ask the examiner to compare both hands directly

Pain considerations: Atrophy itself does not cause pain but indicates the degree of nerve damage underlying your pain condition. Its presence strengthens the objective basis for your neuralgia claim.

Sensory Testing (Light Touch, Pin Prick, Two-Point Discrimination)

The distribution and severity of sensory loss in the median nerve territory: palmar surface of the thumb, index finger, middle finger, and radial half of the ring finger, including the corresponding dorsal fingertips.

What to expect:

The examiner may use a pin, monofilament, or other sensory instruments to test light touch and pain sensation across your hand. They will compare the affected hand to the unaffected side and to standard anatomical maps. Findings are documented in DBQ sensory fields including hand/finger distribution fields.

Key thresholds:

  • Sensory loss confined to median nerve distribution — Anatomically consistent with DC 8715; supports the neuralgia diagnosis
  • Complete sensory loss in median nerve territory — May support rating at the moderate incomplete paralysis ceiling for neuralgia per 38 CFR 4.124
  • Allodynia or hypersensitivity — Indicates active nerve irritation; describe the quality and triggers of hypersensitivity

Tips:

  • Tell the examiner every area where sensation feels different - reduced, absent, burning, or hypersensitive
  • Do not assume the examiner will find all your sensory abnormalities; actively report each one
  • Describe whether your sensory symptoms are constant, intermittent, or triggered by specific activities or positions

Pain considerations: Neuralgia is characterized by pain in the nerve distribution - describe the quality (burning, shooting, aching, electric) and the pattern (constant vs. intermittent, nocturnal worsening, activity-triggered) in detail.

Electrodiagnostic Studies Review (EMG/NCV)

Nerve conduction velocity and electromyography assess the degree of median nerve demyelination and axonal loss. These studies provide objective quantification of nerve dysfunction.

What to expect:

The examiner will review any existing EMG/NCV results in your records. They may note the date, findings, and severity classification. This is documented in DBQ field PUBLICDBQNEUROPERIPHERALNERVES_813_IFYESPROVIDETYPEOFTESTORPROCEDUREDATEANDRESULTSBRI.

Key thresholds:

  • Prolonged distal latency or reduced conduction velocity in median nerve — Objective confirmation of median nerve impairment; strengthens the claim
  • Absent median nerve response — Supports severe dysfunction; may approach complete paralysis criteria
  • Normal EMG/NCV with clinical symptoms — Does not negate neuralgia; 38 CFR 4.124 neuralgia can be rated based on clinical symptoms even without abnormal electrodiagnostics

Tips:

  • Bring a copy of all EMG/NCV reports to the exam
  • If you have not had EMG/NCV studies, ask your treating provider about ordering them before the exam
  • Know the date and location of each test - the examiner needs this for documentation
  • Normal EMG does not mean your symptoms are not real; neuralgia can exist with normal electrodiagnostics

Pain considerations: Electrodiagnostic studies measure structural nerve function, not pain intensity. Your subjective pain descriptions remain independently evaluable even if studies are normal or borderline.

Estimate

Rating Criteria Breakdown

20% Moderate incomplete paralysis of the median nerve, or neural ...

Moderate incomplete paralysis of the median nerve, or neuralgia at the maximum ratable level under 38 CFR 4.124. Per M21-1 guidance, the maximum evaluation for neuralgia is the moderate incomplete paralysis level. This rating applies to the most significant and disabling cases of sensory-only involvement, or cases with moderate motor and sensory impairment. For purely sensory impairment, the moderate level should be reserved for the most significant and disabling presentations.

Key Symptoms

  • Moderate, persistent or frequently recurring pain in the median nerve territory
  • Burning, shooting, or electric-quality pain that significantly interferes with function
  • Persistent numbness or paresthesias in thumb, index, middle, and lateral half of ring finger
  • Moderate reduction in grip strength compared to contralateral side
  • Moderate reduction in pinch strength affecting fine motor tasks
  • Nocturnal pain causing sleep disturbance
  • Difficulty with fine motor tasks (writing, buttoning, typing, handling small objects)
  • Positive Tinel's and Phalen's signs with significant symptom reproduction
  • Possible mild thenar atrophy beginning to develop
  • Wrist splint use at night or during activity

CFR: 38 CFR 4.124 establishes moderate incomplete paralysis as the rating ceiling for neuralgia. M21-1, Part V, Subpart iii, 12.A.2.b states: 'The maximum evaluation for neuralgia, characterized usually by a dull and intermittent pain in the distribution of a nerve, should be the evaluation provided for moderate incomplete paralysis of the nerve under the applicable DC.' M21-1 further instructs to reserve the moderate level for the most significant and disabling cases of sensory-only involvement.

10% Mild incomplete paralysis of the median nerve, or neuralgia ...

Mild incomplete paralysis of the median nerve, or neuralgia characterized by mild, intermittent pain in the distribution of the median nerve. Under 38 CFR 4.124, neuralgia ratings are capped at the moderate incomplete paralysis level. For purely sensory impairment, the mild evaluation level is appropriate when sensory symptoms are recurrent but not continuous, are assigned a lower medical grade reflecting less impairment, and/or affect a smaller area in the nerve distribution.

Key Symptoms

  • Mild, intermittent pain in the median nerve distribution (thumb, index, middle, and lateral ring finger, palmar surface)
  • Occasional tingling or numbness, not constant
  • Minimal or no motor weakness
  • Minimal functional impact on grip or pinch
  • Symptoms may be positional or activity-related but resolve with rest
  • No significant muscle atrophy
  • Positive Tinel's or Phalen's without severe symptom reproduction

CFR: 38 CFR 4.124 specifies that neuralgia, characterized usually by a dull and intermittent pain in the distribution of the nerve, should generally receive a rating at the mild incomplete paralysis level when symptoms are recurrent but not continuous and affect a limited area. The mild level reflects less functional impairment than moderate.

How to Describe Your Symptoms

Pain Quality and Character

How to describe:

Describe the exact quality of the pain using specific adjectives. Median nerve neuralgia typically produces burning, shooting, electric, stabbing, or aching pain. Specify whether the pain is constant or comes in waves. Describe the intensity on a 0-10 scale on a typical day AND on your worst day. Identify what triggers or worsens the pain (gripping, repetitive hand use, wrist flexion, cold weather, night) and what provides relief (rest, splinting, elevation).

Worst-day example:

“On my worst days, I wake up at 2 or 3 in the morning with a burning, electric pain shooting from my wrist into my thumb and first two fingers. I have to shake my hand for several minutes before the pain and numbness ease enough for me to fall back asleep. During the day, if I grip a steering wheel or type for more than 10 minutes, the burning starts again and doesn't fully resolve for 30 to 60 minutes after I stop. The pain rates a 7 or 8 out of 10 at its worst.”

What the examiner listens for:

Specific nerve distribution (thumb, index, middle, lateral ring finger), quality descriptors consistent with neuropathic pain (burning, electric, shooting), functional triggers, duration and frequency of episodes, nocturnal pattern (classic for carpal tunnel-type median nerve irritation), and impact on sleep and daily activities.

Understatements to avoid:

Do not say 'it's just some tingling' or 'it comes and goes, it's not that bad.' These minimizations directly correspond to the mild rating level. If your symptoms are genuinely moderate - persistent, functionally limiting, sleep-disrupting - describe them at that level accurately.

Sensory Deficits

How to describe:

Clearly map out all areas of abnormal sensation: reduced sensation (hypoesthesia), absent sensation (anesthesia), abnormal sensitivity to touch (allodynia), or heightened pain response (hyperalgesia). Identify the specific fingers and hand regions affected. Indicate whether sensory loss is constant or fluctuates. Note whether you have difficulty feeling temperature differences, light touch, or texture in the affected fingers.

Worst-day example:

“On my worst days, my index finger and middle finger feel completely numb - like they're wrapped in thick cotton. I can't feel the texture of fabric or the temperature of water in those fingers. My thumb burns and feels hypersensitive so that even a light touch causes pain. I drop objects regularly because I can't feel whether I have a secure grip.”

What the examiner listens for:

Anatomically consistent sensory loss pattern (median nerve territory), mixed sensory findings (some areas numb, others hypersensitive), functional consequences of sensory loss (dropping objects, inability to feel texture, difficulty with temperature discrimination, impaired fine motor tasks), and consistency between subjective report and physical examination findings.

Understatements to avoid:

Do not describe only one finger or minimize the sensory loss to 'occasional tingling.' Report all affected areas and all qualities of sensory abnormality. Do not wait for the examiner to discover sensory loss during testing - volunteer the information.

Motor Weakness and Functional Loss

How to describe:

Describe specific tasks you can no longer perform or perform with difficulty due to hand weakness or pain. Quantify limitations where possible (e.g., 'I can only type for 10 minutes before the pain forces me to stop'). Discuss grip, pinch, and fine motor tasks. Note any dropped objects, difficulty opening containers, writing, using tools, or performing occupational tasks.

Worst-day example:

“On my worst days, I cannot hold a pen long enough to sign my name without burning pain shooting up my wrist. I drop my coffee cup at least once a week because my grip gives out unexpectedly. I cannot open medicine bottles or turn doorknobs with my right hand. My wife helps me with tasks that require fine hand control because I simply cannot perform them reliably.”

What the examiner listens for:

Specific functional tasks affected, frequency of functional failures (dropping objects, task abandonment), compensation strategies used, impact on employment and occupational tasks, and whether weakness is pain-limited (important for DeLuca factors) versus mechanical strength loss.

Understatements to avoid:

Do not say 'I can still use my hand' without qualifying how limited that use is. Avoid saying 'I manage okay' - if you manage only by significantly modifying activities or by using your other hand, that adaptation itself represents functional loss.

Nocturnal Symptoms and Sleep Disturbance

How to describe:

Median nerve neuralgia classically worsens at night due to sustained wrist flexion during sleep. Describe how often you wake at night, what wakes you (pain, numbness, electric sensations), what you must do to relieve symptoms (shake hand, change position, apply heat/ice), how long it takes to return to sleep, and the cumulative impact on daytime fatigue and function.

Worst-day example:

“Most nights I wake up two to four times with burning numbness and electric pain in my thumb and fingers. I have to hang my arm off the bed and shake it for 5 to 10 minutes before I can feel relief. Some nights I cannot return to sleep at all. The next day I am exhausted and have difficulty concentrating at work. I sleep with a wrist splint but it only partially helps.”

What the examiner listens for:

Frequency of nocturnal awakening, bilateral or unilateral pattern, duration of episodes, effectiveness of current management strategies, cumulative fatigue from sleep disruption, and whether a wrist splint is being used nightly (documents the severity of the condition requiring assistive device).

Understatements to avoid:

Do not say 'it sometimes wakes me up' if it wakes you multiple times per week. Describe the average frequency accurately. Do not omit the fatigue impact - sleep disruption from chronic pain has its own functional consequences that the examiner should document.

Flare-Ups and Exacerbating Activities

How to describe:

Describe what triggers your worst symptom episodes (flare-ups), how long they last, how severe they become, and how often they occur. Include both physical triggers (repetitive hand use, gripping, vibration, cold) and positional triggers (wrist flexion, prolonged typing, driving). Describe recovery time needed after a flare.

Worst-day example:

“After a full day of work requiring keyboard use, my symptoms flare severely. The burning pain spreads from my wrist up into my forearm, my fingers feel numb and swollen even though they look normal, and I cannot grip anything without sharp electric shocks. A severe flare takes 24 to 48 hours to calm down even with rest and splinting. During that time, I cannot perform most hand-intensive activities.”

What the examiner listens for:

Specific triggers, duration and severity of flare-ups, recovery time (functional downtime), any pattern that suggests work-relatedness or activity-relatedness, and whether flares are increasing in frequency or severity over time.

Understatements to avoid:

Do not skip describing flare-ups because you are having a relatively good day at the exam. Explicitly tell the examiner: 'Today is a better day than average. My worst days look like this...' The examiner is trained to document worst-day functioning per M21-1 guidance.

Fatigue and Endurance Limitations

How to describe:

Describe how quickly your hand or arm fatigues with use, how this compares to your pre-condition baseline or your other hand, and what functional tasks you cannot complete due to fatigue rather than pain alone. Note whether rest relieves fatigue or whether recovery is prolonged.

Worst-day example:

“Before my condition, I could work with my hands all day without issue. Now, after 20 to 30 minutes of hand-intensive work, my thumb and fingers feel weak and clumsy, the burning pain intensifies, and I lose fine motor control. I have to rest for 30 to 60 minutes before I can attempt the same task again. On bad days, even after rest, full hand function does not return until the next morning.”

What the examiner listens for:

Specific time limits on hand use before fatigue onset, ability to recover with rest and the duration needed, comparison to contralateral hand, and whether fatigue is progressive throughout the day.

Understatements to avoid:

Do not say 'I get a little tired after a while.' Quantify: how long before fatigue, how severe the fatigue, and how long recovery takes. These quantifications directly inform the functional impairment assessment in the DBQ.
