A reverse Phalen's maneuver involves wrist and finger extension held for 1 minute. We showed that this maneuver results in a significantly higher intracarpal canal hydrostatic pressure as compared to a traditional Phalen's or a modified Phalen's maneuver. Additionally, 31 individuals with complaints of carpal tunnel syndrome symptoms and 20 normal controls were evaluated to see what effect the reverse Phalen's maneuver would have on median sensory latency and amplitude. Both groups demonstrated a prolongation of the median sensory revoked response after 1 minute of this maneuver. The control group had a prolongation of 0.05 ms compared to 0.13 ms in the carpal tunnel syndrome group. The difference between the two groups was significant at a p = 0.05 level. This may add to the sensitivity of conventional screening methods.

Carpal tunnel syndrome (CTS) is caused by compression of the median nerve as it travels through the carpal tunnel. Patients commonly experience pain, paresthesia, and, less often, weakness in the distribution of the median nerve. Provocative maneuvers, such as the Phalen test and Tinel sign, have varying sensitivity and specificity for the diagnosis of CTS.

The clinical manifestation of median nerve entrapment at the carpal tunnel level is known as carpal tunnel syndrome (CTS). Electroneurography (ENG) is considered the gold standard in CTS evaluation. We conducted a retrospective study and analyzed some clinical and demographic variables, relating them to the degree of neuropathy using ENG, to better understand the role of ENG in this very common disease.

Objectives: To compare the efficacy of a traditional cock-up splint, which supports the wrist only, with a modified splint that supports the wrist and the metacarpophalangeal (MCP) joints of the medial four digits in the treatment of carpal tunnel syndrome (CTS).
Design: An assessor-blind randomised controlled trial.
Setting: Hospital-based hand therapy clinics.

Article Synopsis
- A meta-analysis was conducted to evaluate the diagnostic validity (sensitivity and specificity) of various physical examination maneuvers for diagnosing carpal tunnel syndrome (CTS), utilizing the PRISMA checklist for methodology.
- The study included 67 articles assessing multiple tests, including Phalen's test (most sensitive), Tinel's sign, and others, analyzing data from a total of 8,924 hands.
- Findings highlighted that while Phalen's test had the highest sensitivity, the static 2-point discrimination test exhibited the best specificity, indicating the need for a combination of tests and patient history for accurate CTS diagnosis due to variability in test effectiveness.

Objective: The purpose of this study was to summarize and evaluate the research on the accuracy of provocative maneuvers to diagnose carpal tunnel syndrome (CTS).
Methods: The MEDLINE, CINAHL, Cochrane, and Embase databases were searched, and studies that assessed the diagnostic accuracy of at least 1 provocative test for CTS were selected. Study characteristics and data about the diagnostic accuracy of the provocative tests for CTS were extracted.
