Hand Function Tests in Carpal Tunnel Syndrome: A Cross-sectional Study

Study Overview
=================
Brief Summary
-----------------
This is a cross-sectional study that aims to establish the test-retest reliability of two standardized tests (Jebsen-Taylor Hand Function Test and Nine-Hole Peg Test) in individuals with carpal tunnel syndrome (CTS). The study will involve at least 50 participants with CTS who will complete the tests twice, with a 1-week interval between the two assessments. The test-retest reliability will be assessed using intraclass correlation coefficient (ICC) and Bland-Altman plots. The study is expected to provide information on the reliability of these tests in individuals with CTS, which can help clinicians more accurately assess hand function and monitor treatment outcomes.

Arms and Interventions

| Participant Group/Arm | Intervention/Treatment |
| --- | --- |
| Carpal Tunnel Syndrome (CTS) Group<br>This group will consist of individuals diagnosed with carpal tunnel syndrome (CTS) who are 18 years of age or older and who are able to provide informed consent to participate in the study. The group will be recruited from a single center and will be asked to complete the Jebsen-Taylor Hand Function Test and the Nine-Hole Peg Test twice, with a 1-week interval between the two assessments. The aim is to establish the test-retest reliability of these tests in individuals with CTS. The group will include at least 50 participants and will be diverse in terms of age, gender, and race/ethnicity to ensure that the study findings are generalizable to a broader population. | Diagnostic Test: Nine-Hole Peg Test<br>* The Nine-Hole Peg Test is a standardized test that measures manual dexterity and finger movement speed in individuals with hand impairments. The test involves the placement of nine pegs in a pegboard, one at a time, and then removal of each peg as quickly as possible using one hand. The test is timed, and the time required to complete the test provides an indication of manual dexterity and finger movement speed. The Nine-Hole Peg Test has been previously validated and is commonly used in clinical practice.<br>Diagnostic Test: Jebsen-Taylor Hand Function Test<br>* is a standardized test that assesses fine motor skills and functional abilities of the hand. The test involves the completion of seven subtests, including writing, simulated page turning, picking up small objects, stacking checkers, lifting large objects, simulated feeding, and stacking cans. Each subtest is timed, and the time required to complete each subtest provides an indication of hand function. The Jebsen-Taylor Hand Function Test has been previously validated and is commonly used in clinical practice.<br>|

Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Test-Retest Reliability of Jebsen-Taylor Hand Function Test and Nine-Hole Peg Test in Individuals with Carpal Tunnel Syndrome | The primary outcome measure of this study is the test-retest reliability of the Jebsen-Taylor Hand Function Test and the Nine-Hole Peg Test in individuals with carpal tunnel syndrome (CTS). Test-retest reliability will be assessed using the intraclass correlation coefficient (ICC) and Bland-Altman plots. | 1-week interval between the two assessments | 

Secondary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Correlation with clinical measures | This secondary outcome measure assesses the inter-rater reliability of the Jebsen-Taylor Hand Function Test and the Nine-Hole Peg Test in individuals with carpal tunnel syndrome (CTS). This will involve comparing the results of the tests administered by two different raters to determine the consistency of the results. | 1-week interval between the two assessments |
