What is being measured
The primary outcome is the main question the study is designed to answer.
Hand Activity Performance
The MAP-Hand (Measure of Activity Performance of the Hand) scale is a scale consisting of 18 items that evaluates the activity performance of the hand. These items are scored between 1 and 4 and the total score ranges from 18 to 72. Lower scores indicate better activity performance. The participants' hand activity performance will be evaluated with the MAP-Hand scale. The reliability and validity of the Turkish form of the MAP-Hand scale was conducted by Bayraktar and colleagues. However, their work has not yet been published. The necessary permissions have been obtained to use the scale.
Measured: 24 weeks
Secondary outcomes (5)
Grip Strength
Hand grip strength will be measured with a Camry brand digital dynamometer. Participants will be assessed in an upright position on a chair with their feet on the floor, with their arm next to their body, elbow in 90-degree flexion, forearm in midrotation and wrist in neutral. Participants were verbally encouraged during the test. Measurements were repeated three times and the highest value will be recorded in kilograms.
Measured: 24 weeks
Pain measurement
The participants' pain intensity during rest, activity and night will be measured with VAS. According to VAS, pain intensity is evaluated on a 10 cm line between 0 (no pain) and 10 (most severe pain). High scores indicate severe pain. Participants will be asked to indicate the intensity of pain they feel on a 10 cm scale.
Measured: 24 weeks
Hand and Finger Skills
The participants' hand and finger skills will be tested with the 9-Hole Peg Test (9-DÇT). The 9-DÇT is a test that measures hand and finger skills in daily life. A pegboard with 9 holes, 3.2 cm wide, each hole 1.3 cm deep, will be placed in front of the participants in a way that it will be in the midline of the body. Participants will be asked to randomly place 9 wooden pins on the 9-hole pegboard as quickly as possible and then remove the pins from the pegboard one by one and put them in the box. At the end of 3 trials, the times will be recorded in seconds with a stopwatch and the shortest time will be recorded. A longer time to complete the test indicates inadequacy in hand-finger skills.
Measured: 24 weeks
Hand Health Status
Hand health status will be assessed with the "Michigan Hand Outcome Questionnaire (MESA)". MESA consists of 37 questions and is a questionnaire with 6 parameters that evaluate general hand function, daily living activities, pain, work, aesthetics and satisfaction. Each question is evaluated with a 5-point Likert scale and a high score indicates a good status.
Measured: 24 weeks
Carpal Tunnel Symptom Severity
The symptom severity and functional status of the participants will be evaluated with the "Boston Carpal Tunnel Syndrome Questionnaire (BCTQ)". BCTQ consists of the symptom severity scale (SSS) and the functional status scale (FSS) that evaluate the patient in two categories. While the SSS consists of 11 items, the FSS consists of 8 items. The average score is calculated by the ratio of the total score obtained to the number of questions. An increase in the average score indicates that the symptom is severe and functional limitation increases.
Measured: 24 weeks
