- Brief Summary
Pes planovalgus is a common foot condition affecting the child population. It is characterized by the partial or complete collapse of the medial longitudinal arch with rearfoot eversion and forefoot abduction, which is associated with changes in lower extremity kinematics during dynamic activity.
The lower extremity chain includes the foot, ankle, knee, and hip joints, with the feet acting as the base of support. However, due to their small size, maintaining balance can be challenging. Any small dynamic change in the foot, as the support base, can impact overall body posture. The foot's arch, which can be pronated or supinated, affects proprioceptive input by altering joint movement, contact area, and muscle strategy for stability. Pes planovalgus, characterized by excessive subtalar pronation, lead to instability and hypermobility, requiring more neuromuscular control to maintain balance. As a result, flat feet can cause pathomechanical issues and compensatory actions in the lower extremity chain, affecting overall body balance.
The short-foot exercise is a well-known method for strengthening intrinsic foot muscles. It involves contracting these muscles to draw the first metatarsophalangeal joint toward the calcaneus, raising the medial longitudinal arch without flexing the toes. Several balance training techniques have been used to improve postural stability. Recently, the short-foot exercise, which emphasizes proper foot positioning, has gained widespread acceptance among physiotherapists.
Taking all of this into account, the aim of this study is to examine the effects of long-term short-foot exercises on balance and functional capacity in children with pes planovalgus.
- Detailed Description
Voluntary children who have been diagnosed with pes planovalgus will be included in the study. Signed voluntary consent will be obtained from caregivers. Participants will be divided into two groups. Study groups will be as follows: a) Short-foot exercise, b) control.

Group Intervention Description Intervention Group Intrinsic and Ectrinsic Exercise Individuals with a diagnosis of pes planovalgus who underwent supervised exercise under the guidance of a physiotherapist for 8 weeks, 1 day a week. Control Group Intrinsic Exercise Individuals with a diagnosis of pes planovalgus who underwent supervised exercise under the guidance of a physiotherapist for 8 weeks, 1 day a week.
- Primary Outcome Measures
Name Time Method Single Leg Stance Test change from baseline balance at 2 months It evaluates the participants' standing balance. The entire lower extremity will be positioned in full extension, while the other side will be positioned in 90 degree flexion of the lower extremity hip and knee. The time will be started when the participants' eyes are closed and the untested feet lose contact with the ground, and the time will be stopped when they put their feet back on the ground or when their body sway increases too much.
Timed-up and Go Test change from baseline balance at 2 months TUG is a measure of dynamic balance and the risk of falling. It entails individuals rising from a chair, walking a distance of 3 feet, turning, and then sitting back down.
- Secondary Outcome Measures
Name Time Method Range of Motion 2 times for 8 weeks For goniometric measurement, the pivot point will be placed on the lateral malleolus. The fixed arm will be held parallel to the lateral midline of the fibula. The mobile arm will follow the lateral midline of the 5th metatarsal bone.
Popliteal Angle Assessment 2 times for 8 weeks It will be used to detect hamstring shortness. The patient will be in the supine position, the tested side hip-knee will be flexed to 90°, and then passive extension will be applied to the knee. Goniometric measurement will be made when the end-feel is felt in the patient's knee joint.
Thomas Test 2 times for 8 weeks The Thomas Test will be used to determine the shortness of the hip flexors. The Thomas test is performed with the patient in the supine position with the gluteal folds on the short side of the stretcher. The untested side lower extremity is pulled towards the abdomen by performing hip-knee flexion; the tested side extremity is checked to see if it is separated from the stretcher.
Duncan-Ely Test 2 times for 8 weeks The Duncan-Ely test will be used to assess rectus femoris spasticity and shortness. In this test, the patient will be asked to lie in a prone position. The physiotherapist will attempt to quickly and passively bring the patient's knee joint on the side being assessed into full flexion. If the heel cannot touch the hip or the hip on the side being tested lifts off the stretcher, the test is considered positive.
Navicular Drop Test (NDT) 2 times for 8 weeks It is one of the static foot assessment tools and represents the sagittal plane displacement of the navicular tuberosity in a neutral position. If the NDT is below 5 mm, the foot is in supination; if it is between 6-8 mm, the foot is neutral; and if it is above 9 mm, the foot is in pronation.
Foot Posture Index-6 (FPI-6) 2 times for 8 weeks FPI-6, which is a simple, fast and reliable method applicable to pediatric feet, defines the static postural analysis of the foot when equal load is applied to both feet during standing. Scores of 0-5 define normal foot; 6-9 define pes planovalgus and 10-12 define advanced pes planovalgus.
6-minutes Walking Test 2 times for 8 weeks It is a useful test to assess functional exercise capacity. Patients are asked to walk as fast as they can down a straight 30-meter corridor for six minutes.
