What is a Waddell test?
What is a Waddell test?
Waddell’s sign was first described by Professor Gordon Waddell to identify patients who are likely to have poor prognosis following low back pain surgery. But it has been misused and misinterpreted, clinically and medico-legally as a test of credibility and to detect malingering.
What is a positive Hoover’s sign?
The Hoover’s sign is when pressure is felt the paretic leg when the non-paretic leg is raised and no pressure is felt in the non-paretic leg when the paretic leg is being raised.
How do you test for malingering?
Malingering detection accuracy is assessed by evaluating each measure’s sensitivity, hit rate, positive predictive power (PPP), and negative predictive power (NPP). Sensitivity refers to the ability of a measure to accurately identify individuals who have the condition the measure is designed to detect.
What is a positive Lasegue’s test?
A positive Lasègue’s sign is one when leg pain is reproduced or pain in the gluteal region passive straight leg raising. The test has a high sensitivity (0.80-0.97) for a low lumbar disc protrusion but has a low specificity (about 0.4).
What is positive SLR?
A positive straight leg raising test (also known as Lasegue sign) results from gluteal or leg pain by passive straight leg flexion with the knee in extension, and it may correlate with nerve root irritation and possible entrapment with decreased nerve excursion.
What is considered a positive straight leg raise?
A positive test elicits pain in the leg, buttock, or back at 60 degrees or less of leg elevation. The pain is typically worsened by dorsiflexion of the ankle or neck flexion, and it is relieved with flexion of the knee and hip. A positive straight leg raise test usually indicates S1 or L5 root irritation.
What does slump test indicate?
The concrete slump test measures the consistency of fresh concrete before it sets. It is performed to check the workability of freshly made concrete, and therefore the ease with which concrete flows. It can also be used as an indicator of an improperly mixed batch.
What are the types of slump?
There are three types of slump that may occur in a slumps test, namely, true slump, shear slump and collapse slump. True slump refers to general drop of the concrete mass evenly all around without disintegration. Shear slump indicates that the concrete lacks cohesion.
What nerve does the slump test?
The Slump test is used to evaluate for lumbar nerve root impingement or irritation. It begins with the patient seated on the table with both hips and knees positioned at 90°. The examiner stands to the side of the patient.
How do you perform a slump test?
The examiner instructs to the patient to flex his/her spine (slump), followed by neck flexion. The examiner then places his/her hand on top of head and has the patient perform knee extension, and dorsiflexion of foot. Finally, the patient is told to return the neck to neutral.
What is the ideal value of slump?
What is the ideal value of slump? Answer 1 In case of a dry sample, slump will be in the range of 25-50 mm that is 1-2 inches. But in case of a wet concrete, the slump may vary from 150-175 mm or say 6-7 inches.
