This study sought elucidate the influence that foot posture has on the relationship between toe flexor strength and functional performance in older adults. The authors recognise the study's limitations: the study cohort was limited to women, and did not measure body kinematics or muscle activity.

Kusagawa, Y., Kurihara, T., Imai, A., Maeo, S., Sugiyama, T., Kanehisa, H., & Isaka, T. (2020). Toe flexor strength is associated with mobility in older adults with pronated and supinated feet but not with neutral feet. Journal of foot and ankle research, 13(1), 55. https://doi.org/10.1186/s13047-020-00422-y

KEY POINTS: TOE FLEXOR STRENGTH & MOBILITY IN OLDER ADULTS

• Both pronated and supinated foot postures influence rearfoot frontal plane motion, plantar pressure distribution, and muscle activity in the lower limb during gait.
• Individuals with pronated feet require increased intrinsic muscle activity to stabilize the...
