Characterization of Fingertips Using MRI Images (FINGERS-COMPRESSION)

August 26, 2025 updated by: Hospices Civils de Lyon

Characterization of Fingertips Using MRI Images : Development of Mechanically Faithful Models Dedicated to Manipulation.

The objectives was to obtain MRI images of the index finger of the subjects without loading and with loadings (normal and shear forces from 1 to 4N).

How is the study designed?

Design Details

  • Primary Purpose: Basic Science
  • Allocation: Non-Randomized
  • Interventional Model: Parallel Assignment
  • Masking: None (Open Label)

Arms and Interventions

Participant Group / Arm
Intervention / Treatment
Experimental: Group no manual work or activity
Subject with an office or student job.
Other: Compression of the fingertip under MRI.
Compression of the fingertip by a static loading on the phalanx distal of the index of the subjects; Then also a shear stress in the transverse direction of the finger. The data provided by the MRI images will be geometric information such as the thickness of the skin and its possible variation as a function of the area of the finger, the total thickness of soft tissues in compression as a function of the variation in l The angle between the axis of the phalanx and the plane of contact; Mechanical type information relating to the displacements and reaction forces, to the internal deformations of the different areas of the finger.
Sham Comparator: Group manual work
Subject working in a manual or predominantly manual.
Other: Compression of the fingertip under MRI.
Compression of the fingertip by a static loading on the phalanx distal of the index of the subjects; Then also a shear stress in the transverse direction of the finger. The data provided by the MRI images will be geometric information such as the thickness of the skin and its possible variation as a function of the area of the finger, the total thickness of soft tissues in compression as a function of the variation in l The angle between the axis of the phalanx and the plane of contact; Mechanical type information relating to the displacements and reaction forces, to the internal deformations of the different areas of the finger.

What is the study measuring?

Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Average fingertip deflection under compression
Time Frame: Day 1
The different stresses will be: compression of the fingertip by a static loading on the phalanx distal of the index of the subjects; Then also a shear stress in the transverse direction of the finger.
Day 1

Secondary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Average fingertip dimensions
Time Frame: Day 1
In order to develop realistic biomechanical models of the fingers allowing the simulation of the grip, an essential step will be the experimental mechanical characterization of the distal phalanges.
Day 1
