“…9 The BBT was originally developed for adult patients in order to assess gross manual dexterity. 19,20 Hence, these tests could represent two approaches to evaluate hand function in children with CP, with different levels of psychometric qualities. [10][11][12][13][14][15] The JTTHF assesses a battery of seven items of unimanual hand functions simulating activities of daily living.…”

METHOD In this retrospective study, the reliability analyses were conducted with paired t-tests considering a short (mean 14d) and a long (mean 120d) time in between two assessment periods. In addition, an intraclass correlation coefficient (ICC) was used to assess the level of congruency. The responsiveness to therapy was conducted with a paired t-test in the whole sample regarding the age, the manual ability level as classified with the Manual Ability Classification System (MACS), and the topography. RESULTSOur main results confirmed the tests' reliability in a short time period for the JTTHF in both hands and for the BBT on the less affected hand. These results were consistent with the ICC. The responsiveness was confirmed, except on the less affected hand for the JTTHF, with similar results for age, MACS, and topography approach.INTERPRETATION This study supports the use of the JTTHF and the BBT to examine changes after short-term interventions for children with CP. These results should be interpreted with association to normative values or with a control group when used over long assessment periods.

“…A recent pilot study reported a significant correlation (Spearman rho = 0.48, p < 0.001) between the Functional Dexterity Test (FDT) and electrophysiological classification [ 20 ]. However, these findings need to be interpreted with caution due to a spectrum bias in the cohort (the severe-to-extreme CTS group was under-represented) and the use of penalty scores, which may have reduced the sensitivity of the test to measure in-hand manipulation [ 18 , 21 ]. Therefore, the use of the FDT to discriminate between subjects needs to be confirmed in a well-balanced sample of individuals with classical CTS symptoms and using the net scores without the penalty system.…”

“…The pegboard tests are objective, can be easily blinded to the results of other diagnostic procedures, and are fully independent of provocative tests. The test falls under the Body Function (b760d control of voluntary movement functions) and Activity and Participation (d440d fine hand use) ICF domains with a focus on capacity [18,19], and meets also the demands that functional performance-based measures are included that are not only pain dependent.…”

Background Dexterity impairments caused by carpal tunnel syndrome (CTS) make working and daily activities challenging. We aimed to investigate: i) the relationship between dexterity and nerve conduction studies (NCS) in workers with classic symptoms presentation; ii) the ability of the Functional Dexterity Test (FDT) to discriminate different levels of CTS severity as classified by NCS; iii) the diagnostic accuracy of a clinical battery composed of the FDT, Phalen’s test and Tinel’s sign. Methods In a convenience sample of individuals diagnosed with CTS, we correlated FDT net scores with the NCS-based classification by means of Spearman’s (rho) test. Discriminative ability of the FDT was assessed by ANOVA, and a ROC curve determined cutoff thresholds. Sensitivity, specificity, and likelihood ratios (LRs) were used to investigate the diagnostic accuracy of the clinical battery. Results Data from 180 hands were collected. The FDT was significantly correlated (rho = 0.25, p < 0.001) with NCS. The FDT was able to discriminate subjects with severe/extreme NCS findings, and two thresholds (0.29–0.36) were identified. Adding the FDT to the provocative tests improved the overall diagnostic accuracy (specificity: 0.97, CI95% 0.83–0.99; LR+: 14.49, CI95% 2.09–100.53). Conclusions Sensorimotor impairments related to CTS can affect hand dexterity. The FDT discriminated patients with severe NCS involvement. Positive results on the clinical battery (Phalen, Tinel, and FDT) could help to confirm the CTS diagnosis, showing a very high specificity and LR+. On the contrary, the low sensitivity is not able to rule out CTS in individuals with negative results.
