What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
Hand Grip StrengthOther
The grip strength of the participants will be performed with a hydraulic hand dynamometer on a chair with back and arm support. The participant will be asked to squeeze the dynamometer with maximum force. The measurement will be performed 3 times and the average value will be recorded.
What is being measured
The primary outcome is the main question the study is designed to answer.
Function
The Turkish version of the Shoulder, Arm and Hand Problems Questionnaire (DASH-T) will be used to assess the functional level of the upper extremity [10]. The DASH-T questionnaire consists of 30 questions. The first 20 questions ask about physical ability and the last 10 questions ask about pain and related functional and environmental limitations. As the score approaches zero, the functional level of the person is high; as the score moves away from zero, the functional level of the person is low.
Measured: Baseline

Grip strength
The grip strength of the participants will be performed with a hydraulic hand dynamometer on a chair with back and arm support. The participant will be asked to squeeze the dynamometer with maximum force. The measurement will be performed 3 times and the average value will be recorded.
Measured: Baseline
Motor imagery
Motor imagery will be assessed through a left/right judgment task in which participants will be required to recognize whether hand images correspond to their left or right side using the Recognise™ application (Neuro Orthopaedic Institute, Adelaide, Australia). For this test, participants will be seated comfortably in front of a table, with both elbows flexed at 90◦ and both index fingers placed at the bottom of the screen of an electronic tablet. Multiple images of forearms (20 on each side) in multiple postures, angles and skin colors will be randomly displayed in the center of the screen of the device. Participants will be given standard instructions to decide as quickly and accurately as possible whether each image is of the right or left hand by clicking on the 'left' (left fingers) or 'right' (right fingers) buttons displayed at the bottom of the screen.
Measured: Baseline
Two-point discrimination
Two-point discrimination will be assessed using a two-dot discriminator placed longitudinally and perpendicular to the index fingertip. The test score is the minimum distance at which the participant can discriminate between two dots in five consecutive trials. The assessment starts with a distance of 4 mm and is gradually reduced or increased depending on the participant's performance. A distance greater than 4 mm is considered impaired
Measured: Baseline

How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Function (time frame: Baseline). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
