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.

Outcome Measures

Primary Outcomes (1)

  • 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).

    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.

    on the day of first evaluation (at day 1)

Secondary Outcomes (2)

  • 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)

  • 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)

Study Arms (1)

Single group

EXPERIMENTAL
