Hoover test: Free template

Key takeaways

The Hoover test is a bedside maneuver that detects functional leg weakness using the body’s involuntary hip movements.

A positive result means voluntary hip flexion is weak while involuntary hip extension on the opposite side stays strong.

Reported sensitivity runs from 63% to 100% and specificity approaches 100%, making it one of the most dependable positive signs.

Functional neurological disorder is now diagnosed on positive signs like this one, rather than by ruling everything else out.

Charles Hoover published the sign in 1908 as a check for malingering, and modern practice reads it the other way around.

Telling functional lower limb weakness apart from a structural cause is one of the harder calls at the bedside. The Hoover test settles much of it in under a minute. It compares what the patient can do on purpose with what their body does automatically.

This guide covers the procedure, how to read the result, and where the sign misleads you. It also shows how to write the findings up so the next clinician can act.

What is the Hoover test?

The Hoover test is a bedside neurological exam that separates functional lower limb weakness from a structural cause. Named after Charles Franklin Hoover, the physician who first described it in 1908, it rests on a reflex everybody has. When a healthy person lifts one leg, the opposite hip extensors fire automatically to anchor the pelvis.

In functional weakness, that involuntary contraction is still there. The patient reports a leg that will not lift, yet the same muscles work normally the moment attention moves elsewhere. That contrast is what you are testing for.

There is a twist in the history worth knowing. Hoover presented the sign as a way to catch patients faking paralysis, and for decades it was taught that way. Neurology now uses it for the opposite purpose. A positive result supports a diagnosis of functional neurological disorder, which is a genuine condition. The DSM-5 classifies that disorder on demonstrable clinical signs, rather than on what has been excluded.

How to perform the test step by step

Positioning and palpation decide whether the result is worth anything. Work through the same six steps every time.

1. Position the patient supine on the exam table. Legs extended, feet about hip-width apart, arms resting at their sides. A neutral posture limits compensatory movement.
2. Palpate the hip extensors of the non-tested leg. Slide your hand under the gluteal region on the unaffected side. This is where you will feel the involuntary extension.
3. Ask the patient to lift the weaker leg. They flex the hip and raise the leg toward the ceiling using whatever strength they have. Don’t assist, and don’t coach the effort.
4. Feel the opposite side during that effort. A normal response is downward pressure into your hand as the gluteal muscles stabilize the pelvis.
5. Judge the strength of that involuntary extension. Note whether it is strong, weak, or absent, then compare it against the voluntary flexion you just watched.
6. Record both observations. The reported voluntary weakness and the involuntary extension are only meaningful side by side.

Grade the voluntary effort with manual muscle testing so you have a number to compare across visits. Physical therapists and neurologists both report that small differences in hand placement change what the test tells you.

How to interpret a positive or negative result

Interpretation comes down to one comparison. Set the weakness the patient reports against the involuntary response you felt.

A positive result does not prove deception. Functional neurological disorder is a recognized condition with measurable motor abnormalities, and the sign identifies its pattern rather than a patient’s intent. How you explain that at the bedside shapes what happens next, and the clinician-written FND guide offers wording that patients tend to accept.

Sensitivity and specificity of the sign

Published evidence puts this among the most dependable bedside signs for functional motor weakness. The numbers below tell you how much weight the result can carry.

Those figures come from peer-reviewed neurology, including a systematic review of positive signs in conversion disorder. The near-perfect specificity is why psychology practices and neurology teams treat it as a cornerstone of diagnosis.

When to use it, and when not to

The test earns its place in a few specific situations. Reach for it when the answer will change what you do next.

• Acute lower limb weakness where stroke, neuropathy, and myopathy are largely excluded, but functional weakness is still on the list
• Suspected functional neurological disorder, where the diagnosis needs positive signs to stand on
• Occupational health and medicolegal assessments that turn on organic versus non-organic weakness, bearing in mind the sign says nothing about intent
• Teaching, where trainees are learning to spot internally consistent signs of functional motor disorders
• Follow-up review of a diagnosed patient, to track how the motor synergy changes during treatment

One sign never carries a diagnosis by itself. Run it inside a full neurological exam checklist, alongside the history, any other positive signs, imaging where indicated, and the psychological context.

Limitations and common pitfalls

The sign fails in predictable ways. Knowing them keeps a false positive out of the record.

• Pain inhibition: Hip or lumbar pain suppresses the involuntary extension, which can read as a positive sign in a patient who has structural pathology
• Structural hip disease: Osteoarthritis, a labral tear, or capsulitis limits involuntary extension for reasons that have nothing to do with function
• Restricted hip extension: A flexion contracture or tight hip flexors blunt the downward pressure you are trying to palpate
• Poor cooperation: A patient who cannot relax may never produce the expected synergy, which gives you a false negative
• Examiner technique: Light palpation, sloppy positioning, or vague instructions all cost you reliability
• Bilateral weakness: The comparison assumes intact hip extensors on one side, so it becomes ambiguous when both legs are affected
• Fatigue: A patient with true weakness who tires quickly can produce the same pattern as a positive sign

How it compares with the hip abductor sign

The hip abductor sign works on the same principle in a different muscle group. Running both gives you two independent readings rather than one.

Two positive signs in the same patient make functional weakness much harder to argue with. Other eponymous bedside maneuvers answer different questions, so keep them separate. The Kernig sign, for instance, points toward meningeal irritation rather than motor synergy.

How to document findings in clinical notes

Write the note so a colleague can repeat the test and compare. The SOAP structure holds the four pieces you need.

1. Subjective: The weakness the patient reports, in their words. For example, «reports right hip flexor weakness for two weeks, worse when walking, no trauma recalled».
2. Objective: The procedure and what you felt. For example, «supine, voluntary right hip flexion 3/5, strong involuntary left hip extension palpated during the attempt».
3. Assessment: Your reading of the two together. For example, «positive sign, consistent with functional weakness, no structural weakness in the contralateral hip extensors».
4. Plan: The next steps, including further signs to test, imaging if indicated, and the referral route. Name the review interval so the follow-up test has a date to sit against.

Keep the wording identical between visits, and copy the same phrasing into your clinical progress notes. Anyone reading the file can then see whether the sign has changed, rather than guess at two differently worded entries.

What’s inside the assessment form

The downloadable form gives the test a fixed shape, so two clinicians in the same practice record it the same way. That consistency is what makes a repeat assessment comparable.

What you get: patient demographics, the presenting complaint, scripted test instructions, and observation fields for voluntary flexion strength and involuntary extension. It closes with positive, negative, and equivocal checkboxes, interpretation prompts, and space for classification and next steps. Print it, or load it into your digital intake forms.

How to use it: read the scripted instruction to the patient, then palpate and observe as described above. Tick the result box before you leave the bedside. Complete the interpretation section while the exam is fresh, and file the form in the patient record the same day.

How Pabau keeps bedside findings in the record

Plenty of practices still print the form, complete it by hand, and scan it into the patient file days later. The scan lands as a flat image. Nobody can search it, and the next reviewer has to open a PDF to find out whether the sign was positive.

Practice management software like Pabau removes that step. You build the assessment sheet once as a digital form, then complete it on a tablet at the bedside. The result saves against that appointment in the patient record, time-stamped and searchable. One query then pulls every positive sign across your caseload.

That pays off at follow-up. Repeat the test three months on and the earlier grading sits directly beside the new one, in the same record. Pabau GO, our iOS app for practitioners, lets you complete the form at the bedside without carrying a laptop around the ward.

Keep bedside findings in the patient record

Pabau’s digital forms turn the Hoover test template into a form your team completes at the bedside. Findings save into the patient record, time-stamped and ready for whoever reviews the case next.

Conclusion

The Hoover test earns its place because it gives you something positive to write down, instead of a list of things you ruled out. That changes the conversation with the patient. You can tell them the circuitry works, which opens the door to treatment rather than another round of scans.

The trade-off is that one sign is not a diagnosis. Pain, a stiff hip, and a tired patient all bend the result. Grade it against the rest of the exam, and write down what could have skewed it.

Download the template, use it at your next assessment, and keep the wording consistent between visits. Book a demo to see how Pabau stores bedside assessments in the patient record.
