Effects of Pilates Exercise Training on Static Balance and Lower Limbs Proprioception in Adult Females With and Without Flexible Flatfeet

BackgroundIt is well known that flatfeet are associated with a higher incidence of lower limb injuries in different populations. Thus, we examine how Pilates exercise training affects static balance and ankle and knee proprioception in females with and without flexible flatfeet. Study Design. Case series; Level of evidence.MethodsThis quasi-experimental study involves 91 healthy 18- to 25-year-old female university students. The Navicular Drop Test was used to diagnose flatfeet. Pilates included core strength, balance, and flexibility exercises for 16 weeks. Static balance was assessed using the sharpened Romberg test and ankle and knee joint proprioception were measured using joint position reproduction tests. The Wilcoxon test indicated within-group pre-post improvements in static balance, and ankle and knee joint proprioception in the Pilates and the healthy control group (P < .05).ResultsThe between-group comparisons at post-test showed significant differences for joint position reproduction test of the dorsiflexion (P < .05, η² = 0.10) and the plantarflexion (P < 0.05, η² = 0.08) in favor of the healthy controls group. Joint proprioception of ankle and knee was positively correlated with increasing static balance in the healthy control group.ConclusionThe results showed that Pilates has the potential to improve static balance, and ankle and knee proprioception. However, it did not improve postural control and proprioception in individuals with flatfeet. Our findings advise combining Pilates with other interventions to develop flexible flatfeet in females.Levels of Evidence:Level I.
