Functional Improvement and Fine Dexterity in Thumb Tendon Injuries

Condition(s) studied

Investigational drug(s) / intervention(s)

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.

Study 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.

Eligibility

Primary outcome measure(s)

• Goniometric measurement — 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.
• Gross and fine grip strength — 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.
• Michigan Hand Outcomes Questionnaire — 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.
• The O'Connor Finger Dexterity Test — 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.
• The Nelson Hand Reaction Test — 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.
