This test is performed if pes planovalgus was diagnosed during the examination.
Procedure
- Ask the patient to stand with their legs slightly apart.
- Squat behind the patient so that you can observe the dorsomedial side of the foot.
- From this position, perform passive dorsal flexion of the MTP I joint in both the left and the right foot [Figure 138].
Figure 138
- In the case of a flexible (non-contracture) pes planovalgus, the valgus position of the calcaneus is reduced due to the ‘relaxation’ of the flexor hallucis longus muscle and the longitudinal arch of the foot is restored.
