Brief summary
Adult flat foot valgus is a degenerative pathology that causes damage to the ligaments of the hindfoot as well as dysfunction of the tendon of the posterior tibial muscle. Currently, there is a lack of a tool allowing a standardized, reliable, reproducible and validated measurement of the strength of the tendon of the posterior tibial muscle in consultation of foot surgery. The hand-held dynamometer could be that tool. The study would consist in measuring the strength of the tendon of the posterior tibial muscle in healthy subjects with a hand-held dynamometer (MicroFET2) by two examiners and compared to isometric reference measurements (CON-TREX CMV Multi-Joint) to validate the reliability of the measurement and its reproducibility.
Interventions
DIAGNOSTIC_TESTPosterior tibial tendon strength mesure
Posterior tibial tendon strength is assessed with a hand-held dynamometer by two independent observer and with an isometric dynamometer by one observer.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Intra-class correlation coefficient of the inversion force (or supination measured in Newton) of the foot between the measurement made with the hand dynamometer and the measurement made with the isokinetic dynamometer (gold standard). | on the day of first evaluation (at day 1) | Validity of the measurement of the tendon strength of the posterior tibial muscle with a hand-held dynamometer (MicroFET2) compared to the gold standard (CON-TREX CMV Multi-Joint) in subjects. |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Intra-class correlation coefficient of the inversion force of the foot between two measurements made by the same observer with the hand dynamometer (intra-observer reproducibility). | on the day of first evaluation (At day 1) and on the day of second evaluation (at day 2) | the inversion force (or supination measured in Newton). The two measurements will be performed during two consultations one day apart. |
| Intra-class correlation coefficient of the inversion force of the foot between measurements made by two different observers with the hand dynamometer (intra-observer reproducibility). | on the day of first evaluation (At day 1) and on the day of second evaluation (at day 2) | the inversion force (or supination measured in Newton) |
