Thigh, Limitation of Extension C&P Exam Prep

Active Hip Extension (Thigh Extension)

What it measures: The maximum degree of hip extension you can achieve using your own muscle strength. Normal hip extension is 0- (neutral/fully extended) to approximately 20-30- hyperextension. Under DC 5251, the critical threshold is extension limited to 5-.

What to expect: You will likely be asked to lie prone (face down) or stand and extend your leg backward. The examiner will place a goniometer at your hip joint and measure the angle achieved. They will record where pain begins, where motion stops, and whether the endpoint differs from where pain starts.

Pain considerations: Pain on active extension - even if extension exceeds 5- - can still support additional functional loss findings under DeLuca v. Brown and Mitchell v. Shinseki. Tell the examiner the exact degree where pain begins, whether pain is sharp or aching, whether it radiates, and whether pain causes you to stop the motion early. Pain at endpoint is different from pain throughout the arc; both are important.

Passive Hip Extension

What it measures: The maximum degree of hip extension the examiner can achieve by physically moving your leg, without your muscle effort. This isolates structural/anatomical limitation from pain-inhibited active motion.

What to expect: The examiner will gently move your leg into extension while you remain relaxed. This is typically performed in the prone position. The examiner will note whether passive ROM is the same as, or greater than, active ROM, and whether passive motion causes pain.

Pain considerations: Even if passive ROM is greater than active ROM, the presence of pain during passive motion at the functional endpoint is relevant to rating. The examiner should note whether passive motion causes localized tenderness or referred pain.

Weight-Bearing vs. Non-Weight-Bearing Range of Motion

What it measures: Whether your hip extension range of motion differs depending on whether you are bearing weight through the joint (standing/walking) versus in a non-weight-bearing position (lying down). Per Correia v. McDonald, both should be tested.

What to expect: The examiner should test hip extension both while you are standing (weight-bearing) and while lying prone (non-weight-bearing). If only one position is tested, politely ask whether both positions will be evaluated.

Pain considerations: Weight-bearing activities like walking, climbing stairs, and standing from a chair typically provoke more pain and greater functional restriction than lying still. Describe exactly how your hip extension limitation affects these activities and how it compares to rest.

Range of Motion After Repetitive Use (DeLuca Testing)

What it measures: Whether your hip extension limitation worsens after performing the movement three times (or after a period of activity). Per DeLuca v. Brown and Mitchell v. Shinseki, the examiner must assess additional functional loss due to pain, weakness, fatigability, or incoordination with repeated use.

What to expect: The examiner may ask you to perform hip extension (or walking) multiple times and then re-measure your range of motion. They must ask about and document any additional loss with repetition even if they cannot objectively measure the flare-up state.

Pain considerations: DeLuca factors include pain, weakness, fatigability, and incoordination. When describing repetitive use, address each factor: Does the hip become progressively more painful with activity? Does your leg feel weak or give out? Do you tire quickly when walking? Do you stumble or compensate with a limp?

Additional Hip Range of Motion (Flexion, Abduction, Adduction, Rotation)

What it measures: All other planes of hip motion. While DC 5251 specifically rates extension limitation, the examiner will also measure flexion (DC 5252), abduction, adduction, and rotation (DC 5253). Separate evaluations may be assigned without pyramiding.

What to expect: Normal hip ROM: Flexion 0-125-, Extension 0-20/30-, Abduction 0-45-, Adduction 0-30-, Internal Rotation 0-45-, External Rotation 0-45-. Each will be measured actively and passively. The examiner records degrees for each plane of motion.

Pain considerations: Pain during any plane of motion should be verbalized. Even motions that do not meet a compensable threshold may support pain-on-motion findings under 38 CFR 4.59 or additional functional loss under DeLuca.

10%

Hip extension limited to 5 degrees or less under Diagnostic Code 5251. This is the only compensable rating level under DC 5251. Normal hip extension is 0- (neutral/anatomical position) to approximately 20-30- of hyperextension. Extension limited to 5- means the veteran cannot extend the thigh beyond 5 degrees from the neutral/fully-extended position.

From 38 CFR: Per M21-1 guidance: 'Examination shows flexion of the hip limited to 60 degrees and extension limited to 5 degrees. Normal hip ROM is from 0 degrees (fully extended) to 125 degrees (fully flexed). The limitation of extension to 5 degrees is rated 10 percent under 38 CFR 4.71a, DC 5251.' This is the only rating level available under DC 5251.

0%

Hip extension greater than 5 degrees. Under DC 5251, there is no compensable rating below the 5- threshold. However, a 0% (noncompensable) rating may still be assigned for service-connection purposes if the extension limitation does not meet the 5- threshold. Additional codes (DC 5252 for flexion, DC 5253 for abduction/adduction/rotation) may still produce compensable ratings independently.

From 38 CFR: Per M21-1: 'DC 5252 (limitation of flexion) does not list criteria for a 0-percent evaluation, but a 10-percent evaluation requires flexion limited to 45 degrees. Because there is limited flexion not meeting the 10-percent criteria and there is no defined schedular 0-percent evaluation criteria, a 0-percent evaluation is warranted for limited flexion of the hip under DC 5252.' The same logic applies to DC 5251 - extension greater than 5- yields a 0% under DC 5251 specifically.

Pain on Hip Extension

How to describe it: Be specific about when pain starts during the motion arc, where it is located (anterior hip, groin, posterior hip, buttock, thigh), its quality (sharp, aching, burning, stabbing), severity (use a consistent 0-10 scale), and whether it radiates. Distinguish between pain at rest, pain at the start of motion, pain throughout the arc, and pain at the endpoint.

Example: On my worst days, any attempt to extend my hip beyond a few degrees causes a sharp 8/10 pain in my groin and anterior hip that immediately stops me. I cannot walk without a limp and have to take small, shuffling steps to avoid extending my hip.

Examiner listens for: Objective confirmation of pain - visible grimacing, guarding, or stopping motion early. They will check whether the pain endpoint matches the measured ROM endpoint or precedes it. They are also listening for whether pain is consistent with the reported diagnosis.

Avoid: Saying 'it's a little sore' when in fact pain causes you to stop the motion. Do not minimize pain to appear cooperative - accurately report the exact degree of pain and its functional impact.

Functional Limitations on Walking, Standing, and Climbing

How to describe it: Quantify your limitations: How far can you walk before hip pain or stiffness forces you to stop? Can you climb stairs normally or do you need a railing and take one step at a time? How long can you stand before your hip gives you problems? Can you rise from a chair without using your arms to push up?

Example: On my worst days, I cannot walk more than half a block without stopping. I cannot climb stairs without holding both rails. I cannot stand at a kitchen counter for more than five minutes without needing to sit down. Getting up from a low chair requires me to roll to one side and push off with both arms.

Examiner listens for: Specific, quantifiable functional limitations that correlate with the measured ROM restriction. They will note whether the described functional impact is consistent with the degree of extension limitation found on exam.

Avoid: Saying 'I can get around okay' when in reality you use a cane, avoid stairs, or have significantly curtailed your daily activities. Report your ACTUAL functional state, not what you wish you could do.

Flare-Up Description

How to describe it: Describe how often flare-ups occur (daily, weekly, monthly), what triggers them (activity, weather, prolonged standing, sleeping position), how long they last, what symptoms occur during a flare (increased pain, greater stiffness, inability to bear weight), and how they impact your function beyond your baseline.

Example: I have flare-ups about twice a week, typically after any significant walking or after being on my feet for more than 20 minutes. During a flare, my hip locks up completely, I cannot extend my leg at all, and the pain is 9/10. I may be unable to walk without a cane for 1-2 days. I have to lie down and apply heat to recover.

Examiner listens for: Consistency between reported flare pattern and diagnosis. The examiner must document flare-up information even if they cannot observe a flare. Per M21-1, they must address additional functional loss during flare-ups based on the veteran's history and clinical judgment.

Avoid: Failing to mention flare-ups at all because you are not currently in one. Your exam-day presentation may not reflect your worst or even typical functioning - the examiner must ask about and document your flare-up history.

DeLuca Factors - Weakness, Fatigability, Incoordination

How to describe it: Weakness: Describe whether your hip/thigh muscle strength has decreased, whether your leg gives way or buckles, whether you have difficulty with activities requiring hip strength (rising from a squat, climbing, pushing off when walking). Fatigability: How quickly does your hip fatigue during activity? Do you tire more quickly than before your injury? Incoordination: Do you have an unsteady gait, stumble, or compensate in ways that affect your balance or posture?

Example: My hip gives out when I try to walk uphill or up stairs. After walking even one block, the entire hip and thigh feel exhausted and weak - a feeling that used to require miles of walking before my injury. I walk with a visible limp and sometimes catch my foot on the ground because I cannot extend my hip normally for a proper gait cycle.

Examiner listens for: Evidence of any of the four DeLuca factors (pain, weakness, fatigability, incoordination) that would further restrict function beyond what the ROM measurements alone capture. These factors can support an effectively higher rating even when the measured degrees technically fall at the threshold.

Avoid: Saying 'I'm just in pain' without describing the specific DeLuca components. Each factor (weakness, fatigability, incoordination) is independently ratable as additional functional loss - address each one explicitly.

Assistive Device Use

How to describe it: Specify every device you use, when you use it, and why. Do you use a cane for all walking or only when you anticipate longer distances? Do you use a brace? Have you been prescribed any of these by a physician or did you self-procure?

Example: I use a single-point cane every time I leave my home because I cannot trust my hip not to give way. On my worst days, I need crutches. I also use a raised toilet seat and grab bars because I cannot extend my hip sufficiently to lower myself or rise without assistance.

Examiner listens for: Prescription vs. self-procured devices, frequency of use, whether the device is medically necessary, and whether it compensates for extension limitation specifically or for general hip instability.

Avoid: Leaving your assistive device at home or in the car on exam day to 'look better.' Bring and use any device you normally use. The examiner records device use on the DBQ and it directly impacts the overall disability picture.

Impact on Activities of Daily Living and Employment

How to describe it: Describe how the hip extension limitation affects specific daily tasks: dressing (putting on shoes and socks, pants), bathing, sleeping positions, driving, household chores, and any occupational tasks. Be specific about what you can no longer do or do only with difficulty or assistance.

Example: I cannot put on my own shoes and socks without sitting on the bed and bending forward because I cannot extend my hip to reach my feet normally. I cannot sleep on my stomach. I had to stop my job in construction because I cannot walk on uneven terrain or go up ladders. I need help from my spouse to load the dishwasher because bending and extending my hip causes sharp pain.

Examiner listens for: Specific, concrete examples of functional impairment in daily life that correlate with the documented ROM restriction. The DBQ has a dedicated functional impact section (field _851) - the examiner should document this thoroughly.

Avoid: General statements like 'it affects my life a lot' without specific examples. Name the exact activity, describe exactly how the limitation prevents or restricts it, and note whether you have stopped doing it entirely or need assistance.
