What to Expect During Your Exam

Exam Overview

To document the current severity of paralysis or incomplete paralysis of the eleventh (spinal accessory) cranial nerve, including the extent of motor loss affecting the sternocleidomastoid (SCM) and trapezius muscles, for purposes of assigning a disability rating under 38 CFR 4.124a, DC 8211.

What the examiner evaluates:

  • Presence and degree of paralysis of the spinal accessory nerve (complete vs. incomplete)
  • Motor function of the sternocleidomastoid muscle - ability to rotate the head against resistance
  • Motor function of the upper trapezius muscle - ability to shrug the shoulder against resistance
  • Muscle atrophy or wasting of the trapezius and sternocleidomastoid
  • Shoulder drop or winging of the scapula on the affected side
  • Pain associated with nerve injury (constant, intermittent, or dull)
  • Paresthesias or dysesthesias in the neck, shoulder, or upper back region
  • Numbness in the distribution of the affected nerve
  • Difficulty speaking, swallowing, or chewing if concurrent cranial nerve involvement exists
  • Whether symptoms affect the left side, right side, or are bilateral
  • History including etiology, onset, and course of the condition
  • Results of EMG or nerve conduction studies, if available
  • Functional impact on occupational and daily activities
  • Presence of any co-existing cranial nerve conditions (e.g., CN IX, X, XII)
  • Scars or disfigurement related to surgical or traumatic cause

Exam will be conducted in person at a VA facility or contracted exam site. You have the right to request that the exam be recorded in most states. Bring all relevant medical records, treatment notes, and imaging results. The examiner will conduct both a structured interview and a targeted physical/neurological examination focused on the SCM and trapezius muscles.

Typical duration: 30-45 minutes

Sternocleidomastoid (SCM) Muscle Strength Testing

Motor function of the sternocleidomastoid muscle, which rotates the head to the contralateral side and flexes the neck. Weakness or paralysis reflects spinal accessory nerve dysfunction.

What to expect:

The examiner will place a hand against your chin or cheek and ask you to turn your head against resistance. They will compare strength on both sides. They may also ask you to flex your neck forward against resistance. Expect manual muscle testing graded 0-5.

Key thresholds:

  • Absent or trace contraction (grade 0-1/5) — Supports complete paralysis - 30% rating under DC 8211
  • Significantly reduced strength (grade 2-3/5) with marked functional limitation — Supports incomplete, severe paralysis - 20% rating under DC 8211
  • Mildly reduced strength (grade 4/5) with functional limitation — Supports incomplete, moderate paralysis - 10% rating under DC 8211

Tips:

  • Do not 'push through' the pain to appear stronger than you are on your worst typical days.
  • If strength varies day to day, tell the examiner: 'On a bad day I cannot turn my head against any resistance at all.'
  • If fatigue worsens your performance, ask the examiner to retest after repeated movements.
  • Note any pain during resistance testing - this is clinically relevant and should be documented.

Pain considerations: If head rotation or neck flexion against resistance causes pain, state this clearly. Pain during functional testing is a relevant finding under M21-1 guidance and may affect the examiner's severity assessment.

Trapezius Muscle Strength Testing (Shoulder Shrug)

Motor function of the upper trapezius, which elevates the shoulder and stabilizes the scapula. Loss of this function is a primary indicator of spinal accessory nerve paralysis under DC 8211.

What to expect:

The examiner will ask you to shrug your shoulders while they press down on them to test resistance. They will compare side to side. They will also observe your shoulders at rest for asymmetry, drop, or wasting. Expect visual inspection and manual muscle testing.

Key thresholds:

  • No voluntary shoulder elevation on affected side (grade 0-1/5) — Supports complete paralysis - 30% rating under DC 8211
  • Markedly reduced shoulder elevation with visible atrophy and shoulder drop — Supports incomplete, severe paralysis - 20% rating under DC 8211
  • Reduced shoulder elevation with mild weakness and some functional limitation — Supports incomplete, moderate paralysis - 10% rating under DC 8211

Tips:

  • Show the examiner your resting shoulder position - visible shoulder drop or asymmetry is objective evidence of nerve damage.
  • If your trapezius has visibly atrophied (muscle wasting), point this out and ensure it is documented.
  • Inform the examiner if shoulder shrugging causes pain, spasm, or fatigue.
  • If fatigue causes your strength to decline with repeated testing, ask to be re-tested after a few repetitions.

Pain considerations: Shoulder shrugging and overhead activities can produce significant pain when the trapezius is denervated or weakened. Describe the exact pain location (neck, shoulder blade, upper back), character (sharp, burning, aching), severity (numeric scale), and how it limits your ability to raise your arm, carry objects, or maintain posture.

Scapular Position and Winging Assessment

Visual and tactile assessment of scapular positioning. Trapezius weakness from CN XI palsy can cause lateral displacement, inferior rotation, and winging of the scapula, particularly visible when raising the arm.

What to expect:

The examiner will observe your back from behind at rest and during arm movements (e.g., raising your arm forward or to the side). They may palpate the scapula to assess its position. This is an objective measure of functional nerve loss.

Key thresholds:

  • Pronounced scapular winging at rest with inability to elevate the arm beyond 90 degrees — Objective evidence supporting severe or complete paralysis
  • Mild scapular asymmetry with partial arm elevation deficit — Objective evidence supporting moderate incomplete paralysis

Tips:

  • Wear a backless or open-shouldered garment if possible so the examiner can clearly observe the scapula.
  • Demonstrate the motion that causes the most visible winging or asymmetry.
  • If raising your arm above shoulder level is impossible or painful, demonstrate this clearly rather than compensating.
  • Describe how this affects daily activities such as reaching overhead, lifting, dressing, or driving.

Pain considerations: Scapular winging can cause chronic aching in the neck, shoulder, and upper back due to compensatory muscle overuse. Describe this secondary pain burden to the examiner, including how it interrupts sleep or limits sustained activity.

Electromyography (EMG) and Nerve Conduction Study Review

Electrical activity in the trapezius and SCM muscles. EMG can confirm denervation, partial reinnervation, or complete axonal loss, providing objective evidence of the degree of nerve damage.

What to expect:

The examiner will review any existing EMG results in your record. If no prior EMG exists, they may or may not order one. Under M21-1, Part V, Subpart iii, 12.A.2.h, EMG is required unless sufficient clinical evidence already exists in the record.

Key thresholds:

  • Fibrillation potentials and absence of motor unit potentials in trapezius/SCM — Objective evidence of complete or near-complete denervation supporting highest rating level
  • Reduced recruitment with polyphasic motor unit potentials — Objective evidence of incomplete paralysis, severity depends on degree

Tips:

  • Bring copies of any prior EMG or nerve conduction studies to the exam.
  • If you have never had an EMG, you may request that one be ordered to objectively document your nerve damage.
  • Ensure the EMG report specifically evaluated the trapezius and sternocleidomastoid muscles, not just the cervical paraspinals.

Pain considerations: EMG testing itself can be uncomfortable. If you have a low pain threshold due to your condition, inform the technician beforehand.

How to Describe Your Symptoms

Motor Weakness - Shoulder Shrug and Trapezius Function

How to describe:

Describe the specific functional limitations caused by trapezius weakness. For example: 'I cannot lift my right shoulder at all. I cannot carry a bag on my right shoulder because it slides off. I cannot lift items above my waist without my shoulder giving out.' Be specific about which activities you can no longer do or do with great difficulty.

Worst-day example:

“On my worst days, my right shoulder drops completely and I can barely lift my arm away from my side. I cannot hold anything heavier than a cup of coffee. My neck and shoulder blade ache constantly, and I have trouble turning my head to look over my right shoulder when driving.”

What the examiner listens for:

Specific activity limitations tied to trapezius and SCM motor loss, bilateral comparison of function, whether symptoms are constant or episodic, and how long deficits have persisted.

Understatements to avoid:

Do not say 'it's a little weak' if you truly cannot shrug your shoulder against any resistance. Report your actual functional experience on your most symptomatic days, not your best days.

Motor Weakness - Head and Neck Rotation (SCM Function)

How to describe:

Explain that you cannot rotate your head fully to one side, especially against resistance or when driving, exercising, or working. For example: 'I cannot turn my head to the left to check my blind spot when driving without pain and it gives out. My neck tires very quickly and trembles when I try to hold a position.'

Worst-day example:

“On a bad day, I cannot turn my head at all without significant pain and muscle fatigue. I have had to stop driving because I cannot safely check my blind spots. Trying to hold my head in a turned position for even a few seconds causes burning pain and my head returns forward on its own.”

What the examiner listens for:

Whether the weakness affects both the SCM and trapezius or predominantly one, the degree to which the functional deficit limits work and daily activities, and the consistency and duration of symptoms.

Understatements to avoid:

Do not demonstrate only your best performance during the exam. If your strength is much worse after activity or on certain days, say so explicitly: 'Right now I can shrug slightly but by the end of the day I cannot do it at all.'

Pain - Neck, Shoulder, and Upper Back

How to describe:

Describe the character (burning, aching, sharp, stabbing), location (neck base, shoulder blade, upper trapezius, radiating down the arm), severity (0-10 scale), frequency (constant vs. intermittent), and aggravating factors (sustained postures, lifting, turning the head, sleeping on the affected side).

Worst-day example:

“On my worst days, the pain in my left neck and shoulder blade is an 8 out of 10. It is a constant burning ache that spikes to sharp pain if I try to lift anything or turn my head. I cannot sleep on my left side. The pain wakes me up at night and I require prescription medication to get through the day.”

What the examiner listens for:

Pain type (constant vs. intermittent vs. dull), severity rating, impact on sleep and ADLs, and whether pain is associated with the nerve injury or compensatory muscle overuse.

Understatements to avoid:

Do not minimize pain because you are managing it with medication. Report your pain level as it would be WITHOUT medication, and also describe the pain you still experience WHILE on medication.

Paresthesias, Dysesthesias, and Numbness

How to describe:

Describe any abnormal sensations in the neck, posterior shoulder, or upper back including tingling, burning, electric-shock sensations, or numbness. Note whether these are constant or triggered by movement. For example: 'I have a persistent tingling and burning sensation along the left side of my neck that runs into my shoulder blade. It is always there but gets worse when I turn my head.'

Worst-day example:

“On a bad day, the left side of my neck and shoulder feel numb and tingly from the time I wake up. Any movement of my head makes the tingling turn into a sharp electric sensation. It is distracting at work and I cannot focus.”

What the examiner listens for:

The anatomical distribution of sensory symptoms (within or outside the CN XI territory), consistency of symptoms, whether sensory findings correlate with motor findings, and severity ratings.

Understatements to avoid:

Do not ignore sensory symptoms as 'not important' compared to weakness. Paresthesias and numbness are rated DBQ checkboxes that directly support the severity finding.

Functional Impact on Work and Daily Activities

How to describe:

Be specific about what you can no longer do or do only with significant difficulty because of this nerve condition. Include job duties, household tasks, personal care, recreation, and social activities. For example: 'I was a carpenter and can no longer lift materials overhead, use a nail gun, or turn my head safely when operating equipment. I have been placed on light duty and may lose my job.'

Worst-day example:

“On my worst days, I cannot dress myself without help because I cannot raise my right arm to put on a shirt. I cannot drive. I cannot prepare meals that require lifting pots. I cannot sleep comfortably in any position. I spend most of the day managing pain rather than functioning productively.”

What the examiner listens for:

The specific link between CN XI motor loss and functional impairment, whether impairment affects both work and personal life, the consistency and chronicity of impairment, and whether any accommodations or assistive devices are required.

Understatements to avoid:

Do not say 'I manage okay' if you have had to significantly modify your life, reduce work hours, switch jobs, or rely on others for assistance. Accurately describe the impact without minimizing.

Muscle Atrophy and Visible Deformity

How to describe:

If there is visible wasting of the trapezius or SCM muscle, or a noticeable shoulder drop or asymmetry, describe this clearly. For example: 'You can visibly see that my right trapezius muscle is much smaller than the left. My right shoulder sits lower and the shoulder blade sticks out noticeably, especially when I raise my arm.'

Worst-day example:

“The muscle wasting on my right side is visible in photographs. My right shoulder sits at least an inch lower than my left. My shoulder blade protrudes when I try to lift my arm, which limits how high I can raise it and causes additional pain and embarrassment.”

What the examiner listens for:

Objective visual and palpatory evidence of denervation atrophy, scapular winging, and shoulder drop, all of which are objective markers supporting higher severity ratings.

Understatements to avoid:

Do not wear bulky clothing that hides shoulder asymmetry. Wear form-fitting clothing from the waist up so the examiner can observe scapular position, muscle bulk, and shoulder height bilaterally.
