The Angle of the Metacarpophalangeal Joint of the Thumb During Maximal Pinch Strength

The aim of the study is to measure the position of the metacarpophalangeal joint of the thumb during key-pinch, tripod-pinch and opposition-pinch in normal volunteers, to determine the optimal position of metacarpophalangeal joint arthrodesis.

About this study

The aim of the study is to measure the position of the metacarpophalangeal (MCP) joint of the thumb during key-pinch, tripod-pinch and opposition-pinch in normal volunteers, to determine the optimal position of metacarpophalangeal joint arthrodesis.

The force will be measured in three positions (key-pinch, tripod-pinch and opposition-pinch). Also measured is the degree of flexion of the MCP joint of the thumb. The mobility of the MCP joint of the thumb in maximum flexion and extension will also be measured. A total of about 300 healthy volunteers will be examined, with no history of trauma or disease to tendons or joints of the thumbs and between the ages of 18 and 40. The sponsor of this study is Professor Nadine Hollevoet. Master students of medicine from the faculty of medicine and health sciences will be part of the research team.

  2. the angle of the metacarpophalangeal joint of the thumb (in degrees)

    Time frame: 10 minutes

    the angle of the metacarpophalangeal joint of the thumb (in degrees) during maximal force in the three pinch positions

  3. range of motion of the metacarpophalangeal joint of the thumb (in degrees)

    Time frame: 10 minutes

    range of motion of the metacarpophalangeal joint of the thumb (in degrees) measuring maximal flexion and maximal extension of the joint
