Investigation of Inter-rater and Test-retest Reliability of Y Balance Test in Assessment of Dynamic Balance in Individuals With Pes Planus

Pes Planus is characterized by the descent of the medial longitudinal arch, eversion of the hindfoot, and dorsiflexion and abduction of the midfoot. Disorders in the bones of the foot, dysfunction of the tibialis posterior muscle, shortness of the Achilles tendon or weakness in the muscles may pose a risk for pes planus.

In a study in which 80 female participants aged 65 and over participated voluntarily, it was shown that 90% of the deformities seen in the foot were pes planus. In another study conducted with adults aged 18-21 years, pes planus was found with a rate of 13.6%. In a study in a group of 500 people aged 18-25 years, this rate was found to be 29%.

Since exercise, physical activity and walking for a long time will cause foot and leg pain in people with pes planus, the level of physical activity of these people may be limited. There are studies examining the relationship between pes planus and different physical parameters. It has been determined as a result of some studies that the balance, which is one of these parameters, is negatively affected by the presence of pes planus.

According to the literature, many studies have used the Y test in the evaluation of dynamic balance in individuals with pes planus. However the reliability of the Y Balance Test, which is a valid and reliable method for assessing balance in healthy individuals, has not been found in individuals with pes planus.
