“…23 Above that, consistent with previous findings, the Semmes-Weinstein monofilament test showed an age-related association for the healthy side, whereas the Pressure-Specified Sensory Device turned out to be independent of aging processes. 17,37 In summary, the Pressure-Specified Sensory Device proved to be superior to the SemmesWeinstein monofilament test, emphasizing that the Pressure-Specified Sensory Device, too, is a handheld instrument being influenced by the examiner's inherent vibration. Future research and engineering might therefore focus on an automated application of the Pressure-Specified Sensory Device-utterly eliminating potential examiner influence.…”

BACKGROUND: As the sophistication of functional reconstruction procedures continues to increase, so does the need for valid, precise, and reliable instruments to assess their clinical results. The authors compare two tests for spatial resolution and two for cutaneous pressure threshold in an adult patient cohort having undergone microsurgical digital nerve repair after traumatic transection. METHODS: Patients who underwent epineural coaptation after digital nerve transection at the authors' institution between June of 2006 and December of 2011 were asked to participate in a follow-up examination assessing spatial resolution (two-point discrimination and grating orientation test) and cutaneous pressure threshold (Semmes-Weinstein monofilament test and pressure-specifying sensory device). Interinstrument correlations were conducted and critically elucidated. RESULTS: Eighty-one patients (26 female and 55 male patients; median age, 42 years; interquartile range, 23 years) were examined with a mean follow-up period of 3.5 ± 1.4 years. Although all tests could differentiate between the healthy and operated fingers, poor to moderate correlations were found between two-point discrimination and grating orientation test ((operated) = 0.483, p < 0.0001; (healthy) = 0.350, p < 0.0001), and between SemmesWeinstein monofilament test and Pressure-Specified Sensory Device testing ((operated) = 0.287, p = 0.01; (healthy) = 0.382, p < 0.001), indicating that they measure different properties. Altogether, the grating orientation test proved superior to two-point discrimination, whereas Pressure-Specified Sensory Device testing was superior to Semmes-Weinstein monofilament testing. CONCLUSIONS: Thoughtful use of test instruments is advisable when assessing sensibility of the hand. This study suggests including Pressure-Specified Sensory Device testing to assess cutaneous pressure threshold and the grating orientation test to assess spatial resolution in clinical, routine test batteries.

“…The results of this study showed resemblance to the study by Dellon et al 10 with patients exhibiting upper arm compression syndromes. The most effective parameters for the diagnosis of carpal tunnel syndrome, in other words, those with greater sensibility, were the two-point tests, both static and dynamic (2 LP and 2 RP).…”

Objective: The aim of this study is to describe the use of the PSSD (Pressure specified sensory Device) for the diagnosis of carpal tunnel syndrome. Methods: The PSSD is a tool that incorporates a pressure transducer with two prongs, linked to a computer capable of measuring the cutaneous pressure thresholds. The patients were divided in two groups: Group 1-patients neither with superior limb neuropathy nor renal insufficiency. Group 2-patients with carpal tunnel syndrome related to hemodialysis. Group 2 -patients with carpal tunnel syndrome but no renal insufficiency. Results: The results showed, for two of the four parameters measured, that the group 2 had more benefits for the diagnosis of carpal tunnel syndrome than group 3. Conclusion: The PSSD is useful as a diagnostic tool in hemodialysis-related carpal tunnel syndrome Level of Evidence: Level II, development of diagnostic.

Carpal Tunnel Syndrome (CTS) is a pressure-induced neuropathy that causes sensorimotor disturbances of the median nerve, which impair functional ability. A clear history that elicits relevant personal and work exposures and the nature of symptoms can lead to a high probability of a correct diagnosis. Hand diagrams and diagnostic questionnaires are available to provide structure to this process. A variety of provocative tests have been described and have variable accuracy. The Phalen's wrist flexion and the carpal compression tests have the highest overall accuracy, while Tinel's nerve percussion test is more specific to axonal damage that may occur as a result of moderate to severe CTS. Sensory evaluation of light touch, vibration, or current perception thresholds can detect early sensory changes, whereas 2-point discrimination changes and thenar atrophy indicate loss of nerve fibers occurring with more severe disease. Electrodiagnosis can encompass a variety of tests and is commonly used to assess the presence/severity of neuropathic changes and to preclude alternative diagnoses that overlap with CTS in presentation. The pathophysiologic changes occurring with different stages of nerve compression must be considered when interpreting diagnostic test results and predicting response to physical therapy management.
