Functional Improvement and Fine Dexterity in Thumb Tendon Injuries

February 4, 2026 updated by: UMUT ERASLAN, Pamukkale University

Investigation of the Relationship Between Functional Improvement and Changes in Fine Manual Dexterity in Isolated Thumb Tendon Injuries

Considering the thumb's contribution to fine dexterity and precision grip, this study aims to evaluate fine manual dexterity alongside functional outcomes following isolated thumb tendon injuries, and to examine the relationship between postoperative functional improvement and changes in fine manual dexterity.

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Study Type

Study Type

Describes the nature of a clinical study. Study types include interventional studies (also called clinical trials), observational studies (including patient registries), and expanded access.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Cohorts and Interventions

Group / Cohort

Group / Cohort

A group or subgroup of participants in an observational study that is assessed for biomedical or health outcomes.
Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.
Patients diagnosed with isolated thumb tendon injuries at the hand level, who underwent surgical tre
Other: Questionnaire and Physical Exam
Joint range of motion, fine manual dexterity, reaction time, and grip strength will be assessed, and the Michigan Hand Outcomes Questionnaire will be administered to the patients.

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Goniometric measurement
Time Frame: At postoperative 12th and 24th week
Joint mobility will be measured in degrees (°) using a universal goniometer. Active flexion and extension of the Metacarpophalangeal (MCP) and Interphalangeal (IP) joints will be recorded. Higher degrees indicate better joint mobility.
At postoperative 12th and 24th week
Gross and fine grip strength
Time Frame: At postoperative 12th and 24th week
Gross grip strength will be measured in kilograms (kg) using a Jamar Hand Dynamometer. Fine grip strength will be measured in kilograms (kg) using a Jamar Pinch gauge. Key pinch, tip-to-tip pinch, tripod pinch and pulp-to-pulp pinch strengths will be assessed. Patients will perform three maximum effort trials, and the mean value will be recorded. Higher values indicate greater strength.
At postoperative 12th and 24th week
Michigan Hand Outcomes Questionnaire
Time Frame: At postoperative 12th and 24th week
he questionnaire covers 6 domains: overall hand function, activities of daily living, pain, work performance, appearance, and satisfaction. Total scores range from 0 to 100. For the pain domain, higher scores indicate more pain; for all other domains, higher scores indicate better hand function.
At postoperative 12th and 24th week
The O'Connor Finger Dexterity Test
Time Frame: At postoperative 12th and 24th week
The unit of measure is the time in seconds required to complete the placement of pins in the board. Lower time values indicate better fine motor skill and manual dexterity.
At postoperative 12th and 24th week
The Nelson Hand Reaction Test
Time Frame: At postoperative 12th and 24th week
The participant's reaction is measured by the distance the ruler falls before being caught measured in centimeters.Lower values (shorter distance) indicate faster reaction speed and better neuromuscular coordination.
At postoperative 12th and 24th week

Study Major Dates

Study Start (Estimated)

Study Start

The actual date on which the first participant was enrolled in a clinical study. The "anticipated" study start date is the date that the researchers think will be the study start date.

Primary Completion (Estimated)

Primary Completion

The date on which the last participant in a clinical study was examined or received an intervention to collect final data for the primary outcome measure. Whether the clinical study ended according to the protocol or was terminated does not affect this date. For clinical studies with more than one primary outcome measure with different completion dates, this term refers to the date on which data collection is completed for all the primary outcome measures. The "anticipated" primary completion date is the date that the researchers think will be the primary completion date for the study.
