The SCT was positive in the affected forearm in all clinical assessments before surgery and it was negative in all after median nerve release. An anatomical reason for nerve compression was identified in all cases at operation. The SCT is a useful tool for the diagnosis of the proximal entrapment of the median nerve. There are several provocative tests to aid in the diagnosis of nerve compression. The ‘Scratch Collapse Test’ (SCT) has emerged as a new provocative test to assist in the localisation of .

The original search terms included “scratch collapse test” and “carpal tunnel syndrome” or “median nerve entrapment”; however, articles were missed with these search terms; therefore, the authors performed a broader search using only “scratch collapse test” to ensure articles were not overlooked.The diagnosis of nerve compression relies on collecting diagnostic clues from the history, physical examination, imaging and diagnostic testing. There are several provocative tests to aid in the diagnosis of nerve compression. The 'Scratch Collapse Test' (SCT) has emerged as a new provocative test t . Dr. Ebraheim’s educational animated video describes the scratch collapse test for testing nerve compression or injury in the arm.This test is created and use. Methods. The scratch collapse test was prospectively compared with Tinel's sign and flexion/nerve compression in 169 patients and 109 controls. One hundred nineteen patients were diagnosed with carpal tunnel syndrome and 70 patients were diagnosed with cubital tunnel syndrome based on history, examination, and positive electrodiagnostic test.

Methods. Observational study carried out, in 90 patients divided into three groups of 30 patients, taking into account the electromyographic study of the median nerve in the carpal tunnel (no alteration, moderate, severe).The external rotation of the shoulder was measured in four different situations (no scratch, scratch over the carpal tunnel, scratch in the dorsum of .

Proximal median nerve entrapment (PMNE, or pronator syndrome) at the elbow has traditionally been considered an elusive and rare diagnosis, as it is seldom detectable using electrophysiological techniques. . and positive scratch collapse test. Surgical release in local anesthesia allows for a safe, ambulatory, and cost-efficient procedure .

Pain over the median nerve at the medial edge of the lacertus fibrosus1. A positive scratch collapse test over the median nerve at the elbow. Clip 20-2 demonstrates clinical examination of lacertus syndrome showing weakness of FCR, FDP2, FPL, tenderness under lacertus fibrosis, and positive scratch collapse test. The Scratch Collapse Test (SCT) is used to assist in the clinical evaluation of patients with ulnar nerve compression. The purpose of this study is to introduce the hierarchical SCT as a physical .

The scratch collapse test is a recently described provocative test for diagnosis of peripheral nerve compression. The scratch collapse test was studied prospectively in 24 consecutive patients .The original search terms included “scratch collapse test” and “carpal tunnel syndrome” or “median nerve entrapment”; however, articles were missed with these search terms; therefore, the authors performed a broader search using .

Background:The scratch-collapse test (SCT) is a provocative maneuver used to diagnose compressive neuropathies. . the median nerve has already significantly branched. In addition, there is variable neuroanatomy .

The scratch collapse test is a useful tool for the diagnosis of the proximal entrapment of the median nerve in the forearm and an anatomical reason for nerve compression was identified in all cases at operation. Our purpose was to review the clinical usefulness of the scratch collapse test (SCT) in the diagnosis of proximal entrapment of the median nerve in .

The most common nerve compression in the upper extremity is that of carpal tunnel syndrome. Although generally recognized and treated, as much as a 20% failure rate is reported. Recent publications are indicating that one of the sources of persistent median nerve symptoms may be missed proximal median nerve entrapments, of which the lacertus fibrosus . Lacertus syndrome (LS) is caused by compression of the median nerve at the lacertus fibrosus, a fibrous band distal to the elbow joint (Fig. 1).It shows a distinct clinical presentation, primarily characterized by loss of hand strength and endurance and forearm pain, alongside occasional numbness in the median nerve territory [1].The syndrome's hallmark is a .Number of times the scratch collapse test was performed 352 204 120 28 *Kappa, sensitivities, and speciﬁcities were not calculated for technician 3 owing to the low number of times she performed the scratch collapse test. TABLE 2. CTS-6 Score11 Finding Points* Numbness in a median nerve distribution 3.5 Nocturnal symptoms 4 Thenar atrophy or .

• In median nerve injury patterns, when the denervation time permits (3 to 6 months or less is ideal), restoration of pronation is critical and can be accomplished through radial to median nerve transfer procedures (for example the extensor carpi radialis brevis nerve branch may be transferred to the pronator teres nerve branch). MRI results will also likely come back negative for PMNE. A prospective study of 44 participants with PMNE used (1) weakness in median innervated muscles distal to the lacertus fibrosus, (2) pain with palpation over the median nerve at the level of the lacertus fibrosus, and (3) a positive scratch collapse provocative test, as diagnostic criteria.

PMNE at the level of the lacertus fibrosus should be called lacertus tunnel syndrome to distinguish it from other levels of median nerve entrapment. It is a clinical diagnosis based on three distinct clinical findings: weakness, pain over point of compression, . The patients were equally distributed between right/left hands (23/21) and the dominant hand was treated in 56 % of cases. The diagnosis was based on: (1) weakness in median innervated muscles distal to the lacertus fibrosus; (2) pain upon pressure over the median nerve at the level of the lacertus fibrosus; and (3) positive scratch collapse test.Introduction [edit | edit source]. Pronator Teres Syndrome (PTS) is a compression neuropathy of the median nerve at the elbow. It is not as common as compression at the wrist which is Carpal Tunnel Syndrome (CTS). PTS and CTS present similarly, however PTS can be distinguished by a lack of sensation in the distribution of the palmar cutaneous branch of the median nerve .The research was done in 2016 to find a more suitable diagnostic test for carpal tunnel syndrome among carpal compression test (CCT), Tinel’s test (TT), and Phalen’s test (PT). The study shows sensitivity and specificity of the Carpal compression test were higher than both Tinel's and Phalen's tests.

Apley scratch test. . The test is positive if there is numbness, tingling or pain along the lateral aspect of the hand (median nerve distribution). Figure 6. The Phalen maneuver. Numbness, tingling or pain along the lateral aspect of the hand indicates a positive test.
