About this study

This was a controlled laboratorial, within subject, repeated measures study. The aim of this study was to compare two clinically applied treatment options: Customized arch support orthoses (CASO) and orthotic heel lift (HL) on the effect of ATL in recreational runners with pronated feet. It implicated to provide a better understanding of the types of foot orthoses for flatfeet runners and additional biomechanical evidence for the clinical field to guide orthotic prescription as well as selection for Achilles tendinopathy management.

Who can participate

Healthy volunteers accepted: Yes

Only the study team can determine whether someone qualifies for participation.

Inclusion:

  • Foot Posture Index (FPI) was used as evaluating pronated foot posture. Subjects with FPI scores of 6-12 were recruited in the current study.
  • All participants should be free of Achilles tendinopathy and triceps surae injury for 6 months.
  • no previous surgery.
  • not previously attempted any foot orthoses intervention before this study.

Exclusion:

  • leg-length discrepancy
  • rigid forefoot varus deformity
  • gastrocnemius equinus
  • structural hallux limitus, or rigidus
  • Any musculoskeletal or neurological disorders
