Brief Summary

Pes planus is a common foot problem since childhood, which may include loss of height of the medial longitudinal arch, which is the most important arch supporting the foot, valgus of the hindfoot, and abduction of the midfoot relative to the hindfoot. Muscle shortness, increased joint laxity with obesity, W-shaped sitting, male gender and genetic background are among the factors that can increase the incidence and severity of pes planus in the pediatric population. It has been shown in different studies that pes planus is carried into adulthood at a rate of 4-23%. It is known that there is oxygen consumption from the body during muscle contraction. For this reason, it has been shown in the literature that muscle oxygenation is better and the performance of the individual is better in exercises combined with breathing exercises in the exercise program. Therefore, the investigators hypothesized whether foot shortening exercises combined with breathing would have an effect on muscular activation during foot shortening exercises. It is seen that there is a limited number of studies in the literature evaluating the effect of breathing exercises and combined foot exercises on the activation of the muscles around the feet. For this reason, the aim of this study is to examine the effect of combined respiratory foot shortening exercises on the muscular activations of the foot circumference in individuals with flat feet. Two-way repeated analyses of variance will use to determine the statistical significance of Abductor Hallucis Longus, Tibialis Anterior, and Peroneus Longus electromyography activity. Participants: Ten participants with pes planus.The participants will perform Short Foot Exercises with and without respiratory exercises in sitting and standing positions. Main Outcome Measures: Surface electromyography will use to measure the activity of the Abductor Hallucis Longus, Tibialis anterior, Peroneus Longus. Respiratory exercises may be an effective method for reducing compensatory Tibialis Anterior activity and increasing Abductor Hallucis Longus muscle activity during Short Foot Exercises for individuals with pes planus.

Outcome Measures

Primary Outcomes (1)

  • Measurement of the activity of the Abductor Hallucis Longus, Tibialis Anterior or, Peroneus Longus

    Muscle activity will be measured by surface electromyography. Measurment of activity will be done in three condition. Firstly maximum contraction, secondly on standing condition maximum contraction muscle activity will be measured. Last condition is on standing with restiratory exercises maximum contraction of muscles will be measured. Consequently all parameters will be compared.

Study Arms (2)

Short foot exercise without respiratory exercises

EXPERIMENTAL

The participant will place by the researcher in the standing position so that the width between both feet will equal the width of the pelvis and the second toe will align with the patella. During the Short Foot Exercise, the participant will ask to position the spine straight, maintain the pelvis in a neutral position, and place the centerline of the body. The starting position will be set by the researcher under the same conditions as the midway between the feet. The subjects will give feedback from the researchers to assist in the maintenance of accurate body alignment. SFE, only in a standing position. The participants will keep in contact with the fibular head of the target bar to maintain a constant position during Short Foot Exercises. Afterward, surface EMG measurements will be taken from the same muscle groups for 10 seconds during the foot shortening exercises while without breathing.

Behavioral: exercise
