Does Restriction of the Dominant Hand Due to Injury Improve Non-Dominant Hand Function?
An observational study of Dexterity and Tendon Injuries, run by Gazi University at 1 site in Turkey (Türkiye).
Trial summary
Hand injuries result in the restriction of use of the injured hand within a splint or a plaster during the first 6 weeks which is critical for tissue healing. When the dominant hand is injured, patients experience more difficulty in daily life due to this restriction. Read more about this study

About this study
Hand injuries result in the restriction of use of the injured hand within a splint or a plaster during the first 6 weeks which is critical for tissue healing. When the dominant hand is injured, patients experience more difficulty in daily life due to this restriction. Patients injured on their dominant hand mostly express that they are forced to use their non-dominant hand in their activities and as a result, the function of the non-dominant hand improves. However, the non-dominant hand function has not been analyzed in patients with restricted use of the dominant hand during the tissue healing period.

What is being measured
The primary outcome is the main question the study is designed to answer.
hand function
Hand function will be assessed using the Jebsen Taylor Hand Function Test (JTHFT), a valid tool for evaluating impairment and disability. The test includes tasks involving common grip types in daily life, aiming to measure the speed of task performance. Standardized materials, easily available in clinics, are used. The test has seven tasks: writing a 24-letter text, turning cards, collecting small objects, eating, stacking checkers, collecting light wide objects, and collecting heavy wide objects. A 1-minute rest is given between tasks, and completion time is recorded in seconds. Before evaluation, examples will be provided, and individuals will perform a trial run of each task. In our study, only the unaffected, non-dominant hand will be assessed, starting with a single real assessment after the trial.
Measured: 6 weeks
Secondary outcomes (2)
disability level
Disabilities of the Arm, Shoulder and Hand (DASH) Questionnaire will be measured. This questionnaire is used to assess upper extremity disorders and includes 30 items covering pain, stiffness, weakness, daily activities, and functionality. Patients consider their condition over the past week, with total scores ranging from 0 to 100. Higher scores indicate worse functional status.
Measured: 6 weeks
Grip and pinch strengths
Gross grip strength will be measured with a hydraulic hand dynamometer (Jamar®) and fine grip strength with a pinchmeter. Participants will sit in a chair with back support, following the standard position: arm at the side, elbow at 90° flexion, and wrist neutral. Fine grip strength will be assessed in double (bipod) pinch, triple (tripod) pinch, and lateral grip positions. The forearm will be fully pronated for double and triple pinches, and midpronated for gross grip and lateral grips. Only the healthy non-dominant hand will be assessed. Measurements will be repeated three times, and participants will squeeze as hard as possible. The average of the three trials will be recorded in kilograms.
Measured: 6 weeks

Clinical summary
The research question as the sponsor registered it. This describes what the study plans to test, not what it found.
Hand injuries result in the restriction of use of the injured hand within a splint or a plaster during the first 6 weeks which is critical for tissue healing. When the dominant hand is injured, patients experience more difficulty in daily life due to this restriction. Patients injured on their dominant hand mostly express that they are forced to use their non-dominant hand in their activities and as a result, the function of the non-dominant hand improves. However, the non-dominant hand function has not been analyzed in patients with restricted use of the dominant hand during the tissue healing period.

The record says: finished, as of the sponsor's last update on 4 Mar 2026. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 1 site in Turkey (Türkiye). Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
Are results available for this study?
The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.
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?
hand function (time frame: 6 weeks). 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.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 4 Mar 2026.
