Electrodiagnostic tests should be used if clinical or provocative tests are positive and the patient is considering .This test has a high positive predictive value (0.97), indicating a high probability of cubital tunnel syndrome if positive, with high specificity (0.99) and sensitivity (0.75). Pressure Provocative Test: Pressure is applied to the ulnar nerve at .The basis of the pressure provocative tests can be explained by the ‘double crush hypothesis’ (27,28); that is the concept that a compromised nerve already has a lower threshold to mechanical pressure than an uncompromised nerve so that any additional pressure will more readily cause symptoms of nerve compression when compared to the .
The ULTT A was performed as described by Wainner et al 24 to assess neural tension of the median nerve. 16 The test was negative for symptom provocation. Tinel's sign was positive for reproduction of forearm .see in Figure 1. A provocation test that may help in the diagnosis of CTS, consists in increasing the pressure in the carpal tunnel, for example, if the patient hyperflexes the wrist. In the Phalen´s test, the patient holds his wrists in complete and forced flex-ion (with the dorsal surfaces of both hands together) for up to one minute.
In other studies, the test was per- formed by applying pressure directly over the trans- verse carpal ligament, with the pressure then pre- sumably transmitted to the underlying median nerve.2.3.7.8.10.17-w In 1991, Durkan7 compared the di- agnostic properties of a median nerve pressure test to those of Phalen's test and Tinel's sign in 96 .skin lesions in the territory of the median nerve are possible due to compression of blood vessels in the carpal tunnel [6C] . it was noted that the average pressure change for Phalen's test was 4 mmHg in two minutes versus 34 mmHg at one minute and 42 mmHg at two minutes for the Reverse Phalen test [1C] The Reverse Phalen's test may .Evidence [edit | edit source]. Elbow flexion test as the sensitive of (0.32) provocative test in the diagnosis of cubital tunnel syndrome when combined with pressure on the ulnar nerve..

INTRODUCTION. Carpal tunnel syndrome (CTS) is a clinical condition by the compression of median nerve in the carpal tunnel. Not only CTS has various etiologies, but it is the most common in the compressive entrapment neuropathy, and dominant in women (5.8%) than in men (0.6%), especially in the middle-aged housewives 12, 17).Its symptoms are .Perform hand provocation manoeuvres which may support a diagnosis of CTS. . if tapping lightly over the median nerve at the volar surface of the wrist produces paraesthesia or pain in the median nerve distribution. Durkan's test (carpal tunnel compression test) — positive if direct pressure over the proximal edge of the transverse carpal .

Tinel’s test: positive if tapping lightly over the median nerve at the wrist produces paraesthesia or pain in the median nerve distribution. Carpal tunnel compression test (Durkan’s test) : is positive if pressure over the proximal edge of the carpal ligament (proximal wrist crease) with the thumbs produces or worsens paraesthesia in the .
tests were: elbow flexion (0.321, pressure provocation (0.551, and pressure-flexion test (0.911. The most sensitive provocative test in the diagnosis of cubital tunnel syndrome was elbow flexion when combined with pressure on the ulnar nerve. II Hand Surg 1994; 19A:817-820.)
A new clinical provocative test for diagnosing carpal tunnel syndrome (CTS) is described. The examiner uses his or her fingers to simultaneously exert dorsal pressure on the first metacarpal and pisotriquetral complex and volar pressure on the lunate. The test result is considered positive if symptoms of CTS are reproduced. Thirty-four patients (41 hands) with carpal CTS .The sensitivity of the Tinel sign was 0.70, and at 30 seconds, the sensitivities of the other provocative tests were: elbow flexion (0.32), pressure provocation (0.55), and pressure-flexion test (0.91). The most sensitive provocative test in the diagnosis of cubital tunnel syndrome was elbow flexion when combined with pressure on the ulnar nerve.The Median Nerve begins in the axillary region with the root of median nerves situated in the anterior rami of C5-T1. Median and lateral cords of the brachial plexus are merged and extended as the median nerve. Uniting either in front .The decreased space can result in greater pressure on the nerve roots or other innervated structures, causing pain and weakness. . Positive ULTT (median) Involved cervical rotation less than 60 degrees; Positive Spurling's test; . Cervical Compression Test: equal to the cervical distraction test as it is testing for the same tissues, but .
Purpose: To determine the presence of cubital tunnel syndrome. Test Position: Standing. Performing the Test: The patient is standing and the examiner passively flexes the involved elbow to approximately 20 degrees. Next the .We investigated the value of the carpal compression test (CCT) and the pressure provocative test (PPT) in predicting carpal tunnel syndrome (CTS) in a predominantly male population of veterans. . Carpal compression test and pressure provocative test in veterans with median-distribution paresthesias . Muscle Nerve. 2001 Jan;24(1):107-11. doi . The diagnosis of carpal tunnel syndrome (CTS) usually is based on a patient's complaints and the results of clinical provocative tests. 1., 2. Other methods of examination (e.g., computed tomography scanning, electrophysiologic investigation, ultrasonography, Semmes-Weinstein monofilament testing) require special equipment and experience, may be .

The palpated sites were chosen in regards to the accessibility of the nerve and involved the median nerve in the upper arm and the wrist, the radial nerve in the upper arm, at the distal radius and in the anatomical snuff box and the ulnar nerve in the upper arm and in the ulnar groove at the elbow (see Figure Figure2). 2). Palpation was rated .The Brachial Plexus Compression Test, also called the Morley's Compression Test is used for the assessment of Thoracic Outlet Syndrome which produces tenderness at the root of the neck when pressure is placed over the neurovascular (the brachial plexus and the subclavian vessels) structures in the area of the supraclavicular fossa. The ULTT A was performed as described by Wainner et al 24 to assess neural tension of the median nerve. 16 The test was negative for symptom provocation. Tinel's sign was positive for reproduction of forearm and hand tingling with tapping over the median nerve at the antecubital fossa and proximal forearm, and negative at the cubital and carpal .The examiner places the middle and index finger on the ulnar nerve immediately proximal to the cubital tunnel; Pressure is applied for a total of 60 seconds; The test is reproduced on the other side .

Technique [edit | edit source]. There are different ways described in the .
Interpretation of the Pressure Provocation Test results. If the patient does not experience any numbness, tingling, or pain in the ulnar nerve distribution during the test, this is considered a negative result.A negative result suggests that the patient may not have cubital tunnel syndrome, or that the condition is not severe enough to provoke symptoms under the .
The most dependable provocative maneuver, known as the carpal compression test, involves applying steady pressure directly over the carpal tunnel for 30 seconds (see Image. Carpal Tunnel Physical Exam). A positive test is evident when paresthesias or pain arises within the median nerve distribution during the carpal compression test.
