Multiple Sclerosis (MS) C&P Exam Prep

Muscle Strength Testing (Manual Muscle Test, 0-5 Scale) - All Four Extremities

What it measures: Motor strength in bilateral upper and lower extremities including elbow flexion/extension, wrist flexion/extension, grip, pinch, knee extension, and ankle dorsiflexion/plantar flexion. Findings populate DBQ Section 4C (strength) and 4D (reflexes).

What to expect: The examiner will ask you to resist pushing or pulling against their force in multiple muscle groups. Results are graded 0 (no contraction) to 5 (normal strength). Asymmetry between sides is clinically significant. Results are recorded for right and left upper and lower extremities separately.

Pain considerations: Report any pain, burning, or electrical sensations that accompany weakness. MS-related pain (central sensitization, spasticity pain) reduces effective use of extremities beyond what strength numbers alone show.

Deep Tendon Reflexes (DTR) Testing - Bilateral Upper and Lower Extremities

What it measures: Neurological reflex integrity at biceps (C5-C6), triceps (C7), brachioradialis (C5-C6), knee/patellar (L3-L4), and ankle (S1). Hyperreflexia indicates upper motor neuron (UMN) lesion consistent with MS demyelination. Clonus and Babinski sign are noted separately.

What to expect: Examiner taps tendons with a reflex hammer. Graded 0 (absent) to 4+ (hyperactive with clonus). In MS, hyperreflexia (3+ to 4+) with or without clonus and an upgoing Babinski sign (positive plantar response) are classic upper motor neuron findings supporting the diagnosis and severity. Results recorded in DBQ Section 4D.

Pain considerations: Spasticity from hyperreflexia causes chronic pain, sleep disruption, and functional limitation. Describe pain associated with muscle stiffness and spasms specifically.

Gait Assessment and Tandem Walking

What it measures: Cerebellar function, balance, coordination, and ambulatory ability. The examiner observes for ataxic gait, foot drop, spastic scissor gait, wide-based gait, and ability to perform tandem (heel-to-toe) walking. Findings populate DBQ Section 4A (gait) and inform assistive device need.

What to expect: You will be asked to walk normally and then heel-to-toe in a straight line. The examiner will observe from multiple angles. If your gait is abnormal, the examiner notes the type of abnormality and any contributing conditions. If you use an assistive device for walking, bring it and use it as you normally would.

Pain considerations: Report any pain in the legs, feet, or back that limits your walking distance or speed. Describe how far you can walk before stopping due to fatigue, weakness, or pain.

Coordination and Cerebellar Function Tests (Finger-Nose-Finger, Heel-Shin, Romberg)

What it measures: Cerebellar coordination and proprioception. Finger-nose-finger tests intention tremor and dysmetria in upper extremities. Heel-shin tests lower extremity coordination. Romberg assesses proprioception and vestibular function. Findings populate DBQ Section 4B (coordination/tremor).

What to expect: You will be asked to alternately touch your nose and the examiner's finger, run your heel down your shin, and stand with feet together eyes closed (Romberg test). The examiner looks for tremor, overshoot (past-pointing), and increased sway or falling.

Pain considerations: Coordination deficits cause fatigue through increased muscular effort. Describe how much energy fine motor tasks require and how quickly you fatigue during repetitive hand movements.

Muscle Atrophy Measurement (Circumferential Measurements)

What it measures: Muscle bulk loss due to disuse or neurogenic atrophy. Examiner measures circumference at standardized points on bilateral extremities and documents the difference in centimeters in DBQ field 401. Atrophy checkboxes (DBQ fields 542-545) indicate presence or absence by extremity.

What to expect: Examiner uses a tape measure around your limbs at comparable sites bilaterally. A difference of 2 cm or more is typically considered clinically significant. This measurement provides objective evidence of functional loss beyond what strength testing alone demonstrates.

Pain considerations: Atrophy is often accompanied by chronic pain and weakness. Describe any aching, cramping, or burning in atrophied limbs.

Bladder Dysfunction Evaluation (Clinical Interview + Urological Findings)

What it measures: Nature and severity of neurogenic bladder dysfunction from MS spinal cord demyelination. Assessed via clinical history for urgency, frequency, incontinence, hesitancy, slow stream, post-void residual, UTI history, catheterization need, and urinary appliance use. Corresponds to DBQ Sections 3I, 3J, 3K, 3L, 3M and multiple individual fields.

What to expect: Detailed interview about urinary symptoms. Examiner may ask about urodynamic study results, cystoscopy findings, uroflowmetry peak flow rate, and post-void residuals if available. Bring recent urology records, urodynamic study results, and a list of UTIs treated in the past 12 months.

Pain considerations: Bladder dysfunction causes significant pain (bladder spasms, burning with UTIs), sleep disruption, and social isolation. Describe the emotional and psychological burden of urinary incontinence on your daily life and relationships.

Bowel Dysfunction Evaluation (Clinical Interview)

What it measures: Neurogenic bowel dysfunction including incontinence, constipation, urgency, mucorrhea, abdominal bloating, and need for bowel management program. Corresponds to DBQ Sections 3A-3H, 3F, and bowel medication fields.

What to expect: Interview about bowel habits, incontinence episodes, constipation severity, any prescribed bowel programs (digital stimulation, suppositories, enemas), special diet requirements, and bowel medications.

Pain considerations: Bowel dysfunction causes significant abdominal pain, bloating, and cramping. Describe abdominal pain frequency and whether it is related to defecation.

Fatigue Assessment (Clinical Interview - MS-Specific Fatigue)

What it measures: MS-related fatigue (lassitude), which is distinct from and often more disabling than fatigue in other conditions. Assessed for impact on daily activities, employment, and cognitive function. There is no single objective test; this is primarily a structured clinical interview.

What to expect: The examiner will ask about your energy level, how quickly you fatigue with activity, whether cognitive function worsens with fatigue, and how fatigue affects work, household tasks, and social activities. This is a DeLuca factor (fatigue) and is critical for MS.

Pain considerations: Fatigue in MS is often accompanied by pain, cognitive fog, and emotional distress. Describe the multi-dimensional nature of MS fatigue as distinct from simply feeling tired.

30%

Minimum rating assigned to all veterans with a confirmed diagnosis of Multiple Sclerosis under DC 8018. This minimum applies regardless of current symptom severity. The 30% rating reflects the unpredictable, progressive nature of MS. Veterans with greater functional impairment from specific MS manifestations are rated separately for each residual under the most appropriate diagnostic code, with MS serving as the underlying condition under a hyphenated code (e.g., 8018-5110, 8018-7542, 8018-8520).

From 38 CFR: 38 CFR 4.124a, DC 8018: 'Multiple sclerosis: Minimum rating 30.' Per M21-1 V.iii.12.C.1, a minimum evaluation of 30 percent shall be assigned whenever MS is the diagnosis, with separate evaluations for each residual disability.

60%

Assigned when residual MS manifestations warrant a combined evaluation reflecting significant functional impairment. Achieved through separate ratings for individual manifestations rated under appropriate hyphenated diagnostic codes. Common combinations include bladder dysfunction (DC 7512/7542), lower extremity weakness (DC 8520), visual deficits (DC 6009/6016), dysarthria (DC 6516), and bowel dysfunction (DC 7332). Each residual is evaluated to its full severity under its specific DC.

From 38 CFR: M21-1 coded conclusion example: 8018-7542 40% (MS with bladder dysfunction) + 8520 10% (right lower extremity weakness) + 8520 10% (left lower extremity weakness) = 50% combined; bilateral factor applied. Multiple residuals rated separately and combined per 38 CFR 4.25.

100%

Assigned when MS manifestations result in loss of use of both lower extremities (LOU) under hyphenated DC 8018-5110, or when the combined evaluation of all separately rated MS residuals reaches 100%. Per M21-1 V.iii.12.C.1.d, assign 100% for LOU of both lower extremities and separately rate all other body systems to ensure no entitlement to higher SMC levels is overlooked. Additional separate ratings for bladder, bowel, speech, and vision ensure maximum SMC benefit.

From 38 CFR: M21-1 coded conclusion: 8018-5110 MULTIPLE SCLEROSIS WITH LOSS OF USE BOTH LOWER EXTREMITIES 100% from 06/14/1996 + 6516 DYSARTHRIA 30% + 7332 IMPAIRMENT OF ANAL SPHINCTER CONTROL 10% + 7512 LOSS OF BLADDER CONTROL 10% + 6016 NYSTAGMUS 10%. Combined evaluation 100%. SMC entitlement under 38 U.S.C. 1114(k) for loss of use of a creative organ must be specifically evaluated.

MS Fatigue (Lassitude)

How to describe it: Describe MS fatigue as distinct from normal tiredness. Quantify how many usable hours per day you have before cognitive and physical function deteriorate. Describe the pattern: worse in heat, worse in the afternoon, worse after exertion. State specifically how fatigue affects your ability to work a full day, perform household tasks, and maintain social relationships.

Example: On my worst days, which occur 3-4 times per week, I wake already feeling exhausted despite adequate sleep. By 11 AM my legs feel like lead, my thinking becomes unclear, and I am unable to drive or read. I must lie down for 2-3 hours in the afternoon. I cannot perform any productive activity after 2 PM on these days. I have been unable to maintain full-time employment because I cannot reliably predict which days I will function.

Examiner listens for: Specific time-limited functional capacity, Uhthoff's phenomenon (heat sensitivity), cognitive fatigue distinct from physical fatigue, impact on employment and ADLs, frequency of severe fatigue episodes per week.

Avoid: Saying 'I get tired sometimes' without quantifying duration, frequency, or functional impact. Avoid minimizing fatigue as something you 'push through' without describing the cost of doing so.

Bladder Dysfunction

How to describe it: Describe each component separately: urgency (how little warning you get), frequency (how many times per day and night), leakage episodes (times per day, volume, pad use and change frequency), hesitancy, slow or weak stream, and whether you have incomplete emptying or retention. State UTI frequency in the past 12 months and whether any required hospitalization.

Example: On bad days I have urgent leakage with less than 30 seconds of warning before I am incontinent. I change absorbent pads 4-5 times per day. I wake 3-4 times per night to void. I have had 6 UTIs in the past year, two of which required IV antibiotics. I now plan all outings around bathroom locations and avoid situations where I cannot access a restroom immediately.

Examiner listens for: Pad change frequency (critical for DBQ field selection), UTI frequency, whether catheterization is required, functional and social impact of incontinence, objective test results such as uroflowmetry or post-void residuals.

Avoid: Saying 'I have bladder problems' without quantifying pad changes, UTI frequency, or catheter use. Failing to mention nocturia, which worsens sleep and fatigue.

Mobility and Gait Impairment

How to describe it: State your maximum walking distance before needing to stop, what causes you to stop (pain, weakness, balance, fatigue), whether you use an assistive device and how often, whether you have fallen, and how your walking ability has changed over time. Describe what happens when you try to walk in the heat or after exertion.

Example: On worst days I cannot walk more than 50 feet without holding onto a wall. I use my cane every time I leave the house and keep furniture arranged so I can move safely indoors. I have fallen 4 times in the past 6 months, twice resulting in injury. My right foot drops and catches on uneven surfaces. In summer heat my legs become completely unreliable and I require my wheelchair.

Examiner listens for: Fall frequency and injury history, assistive device type and usage frequency, Uhthoff's phenomenon affecting gait, specific gait abnormality description (foot drop, scissor gait, ataxia), distance limitations.

Avoid: Demonstrating your best walking performance during the exam and not disclosing that this is not representative of typical function. Failing to mention falls, which are a critical safety and functional marker.

Upper Extremity Function and Fine Motor Skills

How to describe it: Describe difficulty with specific tasks: buttoning clothing, using utensils, typing, writing, carrying objects, opening jars. Quantify how long you can perform fine motor tasks before tremor, weakness, or fatigue stops you. Describe whether symptoms are worse in dominant or non-dominant hand and whether spasticity, tremor, or weakness is the primary limiting factor.

Example: I can type for approximately 10 minutes before my right hand becomes clumsy and I make continuous errors. I dropped a full cup of coffee twice last week because my grip released without warning. I can no longer button small buttons independently and use velcro closures. Writing by hand for more than a few lines causes cramping and illegibility.

Examiner listens for: Specific functional task failures, dominance and which extremity is more affected, duration of activity before fatigue or loss of function, tremor type (resting vs. intention), DeLuca factors: repetitive use worsening of symptoms.

Avoid: Saying 'my hands are a little weak' without describing specific task failures or the impact of repetitive use on function.

Pain, Paresthesias, and Sensory Symptoms

How to describe it: Describe sensory symptoms using specific language: burning, electrical shock, band-like pressure around torso or limbs (MS hug), numbness, pins and needles, and hypersensitivity. Describe Lhermitte's sign (electrical sensation down the spine and into extremities with neck flexion). Rate pain on a 0-10 scale for typical and worst days. Describe what worsens and relieves pain.

Example: On my worst days my legs feel like they are on fire from the knee down. I also experience an electrical shock sensation that shoots from my neck down to my feet when I look down at my phone. The burning is constant at a 6/10 and spikes to 9/10 with heat or exertion. My feet are so hypersensitive that wearing socks is painful. This pain prevents me from sleeping and worsens my fatigue cycle.

Examiner listens for: Lhermitte's sign description, neuropathic pain quality and severity, trigeminal neuralgia if applicable, impact on sleep and function, medications used for pain management.

Avoid: Understating pain severity or describing only the average rather than the worst-day experience. Failing to mention Lhermitte's sign, which is pathognomonic for MS and provides strong diagnostic support.

Cognitive Impairment

How to describe it: Describe specific cognitive failures rather than general statements. Focus on memory lapses, word-finding difficulty, processing speed slowing, difficulty with multitasking, and cognitive fatigue. Describe how cognitive symptoms affect work performance and daily management tasks.

Example: I regularly lose track of what I was saying mid-sentence. I cannot reliably remember appointments, medication schedules, or conversations without written reminders. I was let go from my job because I could no longer manage multiple tasks simultaneously. I take twice as long to read and process written materials as I did before my MS diagnosis. On bad days I cannot follow a simple recipe or manage my finances.

Examiner listens for: Specific cognitive task failures, employment impact, whether formal neuropsychological testing has been performed, whether cognitive symptoms are separate from and additive to fatigue.

Avoid: Saying 'I have brain fog' without specific examples. Cognitive impairment in MS is ratable under separate diagnostic codes and should be described with the same specificity as physical symptoms.

Sexual Dysfunction

How to describe it: For male veterans: describe erectile dysfunction severity (partial vs. complete, duration), loss of orgasmic sensation, and impact on relationship and quality of life. For female veterans: describe loss of arousal, decreased genital sensation, lubrication problems, and dyspareunia. State clearly that this is attributed to MS neurological involvement.

Example: I have had complete erectile dysfunction for the past 18 months attributable to my MS. I have tried phosphodiesterase inhibitors without adequate response. This has severely affected my relationship and mental health.

Examiner listens for: Whether dysfunction is neurogenic in origin from MS, severity, treatment attempted, impact on relationship and quality of life. SMC(k) for loss of use of a creative organ is specifically addressed in M21-1 for MS.

Avoid: Omitting sexual dysfunction from the exam discussion due to embarrassment. This symptom is specifically noted in M21-1 MS coded conclusions and may trigger SMC(k) entitlement.

Visual Disturbances

How to describe it: Describe history of optic neuritis (episodes, which eye, whether vision recovered fully), current visual acuity, diplopia (double vision), nystagmus, and how visual symptoms affect driving, reading, and daily activities. Bring ophthalmology or neuro-ophthalmology records.

Example: I had optic neuritis in my right eye in 2019 with partial recovery. My current corrected visual acuity is 20/100 in the right eye. I have intermittent double vision when fatigued that prevents safe driving. A neuro-ophthalmologist documented horizontal nystagmus on my last visit.

Examiner listens for: Optic neuritis history and recovery, current visual acuity in each eye, nystagmus type and severity, diplopia frequency, driving status and impact on independence.

Avoid: Failing to bring ophthalmology records. Visual deficits from MS are rated separately under DC 6009 (optic neuritis) or 6016 (nystagmus) and can significantly increase the combined evaluation.
