Brief Summary

The foot is a terminal joint that opposes external resistance in the lower kinetic chain. It plays a primary role in weight transfer and ground response between the body and the ground. It plays a role in maintaining an upright posture, lowering the gravitational line against a narrow support surface during walking, providing stability and absorbing the shocks that occur during daily life activities. Foot problems are common worldwide. These problems affect people negatively by giving symptoms during activities of daily living.

Outcome Measures

Primary Outcomes (4)

• Foot Function Index

  The foot function index was developed and widely used to measure the effects of foot pathologies on pain, disability and activity limitation. Foot function index; It consists of 23 items in 3 groups as pain, disability and activity limitation. While the pain and disability section consists of 9 questions, the activity limitation consists of 5 questions. The patients answer all the items considering their foot condition one week ago. The score of each section and the total score are calculated and we divide by the sum of the maximum scores of the items and multiply by 100.

• Foot Posture Index

  Foot Posture consists of palpation of 6 regions. 1. Talus head palpation 2. Curvature above and below the lateral malleolus 3. Inversion and eversion of os calcaneus 4. Protrusion in the talonavicular joint area 5. Harmony of the medial longitudinal arch 6. Abduction and adduction of the forefoot section relative to the hindfoot section. Each criterion is evaluated between -2 and +2 and this result is noted. Positive values indicate pronation, negative values indicate supination.

• Single Leg Jump Test (TBS)

  TBS test will be applied to evaluate the lower extremity functional performances of healthy individuals. While individuals are standing on one leg, the other leg is asked to jump forward with the knee bent and the point where the fingertip touches is marked. The jump distance is measured and the test is repeated 3 times and the average result is obtained. In our study, the single leg jump test will be used for both legs.

  1 day

• Y Balance Test

  The leg lengths of all individuals are measured bilaterally. While measuring, individuals are asked to lie in their anterior, posteromedial and posterolateral directions. Each of the participants is informed before the measurement. Measurements were made in both legs and will be repeated 3 times. When calculating the total score, the values in centimeters of the 3 directions are added. Divide by the product of the length of the leg by 3 and multiply the result by 100 to reach the percentile.
