Effects of Dynamic Balance Exercise on Flexible Pes Planus (PesPlanus)

Does Dynamic Balance Exercises Affect Flexible Pes Planus?

The purpose of this study is to investigate the effects of intrinsic strengthening and dynamic balance exercises in patients with flexible pes planus. Forty-five participants aged 18 to 35 years were enrolled in the study, and the first group underwent intrinsic foot muscle strengthening training with short foot exercises (SFE) and used insoles. The second group trained using the dynamic balance board, which promotes dynamic balance and used insoles. The third group used only insoles. The total duration of treatment was 8 weeks/3 days. The degree of foot deformity was assessed with the, medial longitudinal arch (MLA) angle, measurements of subtalar angle and navicular drop test. Foot position assessed using Foot Posture Index (FPI) Static balance was assessed with the Flamingo Balance Test and dynamic balance with the " BOBO Health Platform with Gaming®" device.

Study Overview

• Status: Completed
• Conditions: Pes Planus
• Intervention / Treatment: Other: Short foot exercises, Dynamic balance exercises and insole

Detailed Description

Pes planus (flatfoot) is generally defined as valgus of the hindfoot, disappearance of the medial longitudinal arch (MLA) in the midfoot, and supination of the forefoot relative to the hindfoot when the foot is loaded. MLA height is the most important measurement for determining the degree of pes planus. The decrease in MLA disrupts this balance and causes the muscles and bones that are supposed to balance the effect of external forces to be subjected to greater stress. As a result, the balance is affected. Conservative treatment options that can be used as the first step in treating pes planus include activity modifications, exercises, manipulations, serial cast applications, weight loss, shoes changes, shoes modifications, use of foot orthotics. Several methods are used to strengthen foot intrinsic muscles, including toe towel curls, picking up objects, shin curls, unilateral balance activities, and the short foot exercise. The common exercises are strengthening exercises defined for intrinsic muscles, "short foot exercises" (SF). It is known that arch support insoles improve foot malalignment, correct dynamic posture, effectively support leg alignment and pain relief, and normalize gait. The use of silicone insoles is a product whose range of application has increased in recent years. The extremely soft and flexible material ensures that the shape of the foot is adopted. The researchers believed that the presence of a pes planus foot deformity, common in young people, negatively affects the balance of the individual, revealing small disturbances and different balance strategies. In this situation, the training of intrinsic muscles is of great importance. The investigators aim in this study is to investigate the effects of intrinsic muscle strengthening and dynamic balance exercises performed with silicone soles in individuals with flexible pes planus.

What is the study measuring?

Primary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Dynamic Balance performance	Dynamic balance was assessed using the BOBO Gaming Health Platform. With this system, which acts as a computerized strength platform, there are assessment and treatment phases. The individual was performed with the foot being tested on 2 sides of the platform. In all these evaluations, parameters related to body balance were analyzed. It gives performance scores in terms of percent.	0-8 week

Secondary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Foot Posture Index Score	Foot posture was analyzed using the Foot Posture Index. Palpation of the head of the talus in the hindfoot, inclination below and above the lateral malleolus, pronation/supination of the calcaneus, ballooning at the talonavicular joint in the forefoot, MLA structure, and abduction/adduction of the forefoot relative to the hindfoot were evaluated. Each of these criteria was assigned scores ranging from -2 to +2. The total score obtained was recorded and it indicated that the foot was in neutral position at 0, in pronation at positive values and in supination at negative values.	0-8 week
Subtalar angle	Measurement of the subtalar angle between the Achilles tendon and the midpoint of the calcaneus was measured while the patient stood on a high platform. The pivot point was assumed to be 1 cm below the medial malleolus, and this area was marked. An angle greater than 5 degrees in the pronation or supination direction was considered abnormal.	0-8 week
Static Balance Assessment	The patient flexed the foot behind the knee and held it with the hand in the same direction. When the patient was ready, he released the hand of the physiotherapist and at the same time the stopwatch was started. Each time the patient lost balance (touching the floor, releasing the foot), the stopwatch was stopped and restarted when the patient was ready 60 seconds. The total number of balance losses during this period was reported with number	0-8 week
Angle of Medial longitudinal Arch	While measuring the MLA angle, a line was drawn from the center of the medial malleolus to the center of the navicular. The other line was drawn from the tuberosity of the navicular to the center of the first metatarsal head. The angle between these two lines was measured with a goniometer.	0-8 week
