NCT07388316

Brief Summary

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.

Outcome Measures

Primary Outcomes (5)

  • Goniometric measurement

    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

    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

    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

    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

    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
