Clinical Trial Summary

Foot core training is very important for the intrinsic muscles of the foot, but it is often neglected in exercise programs given to individuals with pes planus. The aim of our study is to reveal the effects of foot core training, which will be added to the exercise program routinely given to individuals with asymptomatic flexible pes planus, on walking, muscular activations, balance and lower extremity functional performance with objective, evidence based results.

Description:

This study is a randomized controlled study and will be carried out on volunteer individuals with asymptomatic flexible pes planus aged between 18-25, studying at Alanya Alaaddin Keykubat University. Persons meeting the inclusion criteria will be determined by the specialist physiotherapist. Surface electromyography (sEMG) measurements will be made by a doctorate physiotherapist. Other evaluations will be made by a specialist physiotherapist. Individuals who meet the inclusion criteria, who volunteered to participate in the study and signed the consent sheet will be randomly divided into two groups, the control group and the foot core group. Individuals with initial evaluations will be followed up in an exercise program planned for 8 weeks. The control group will be given exercises to strengthen the weakened muscles, stretch the shortened structures and increase proprioception. Foot core training will be given to the study group in addition to the exercises given to the control group. Before and after exercise, the subjects will be assessed with navicular height measurement, muscle activation evaluation, evaluation of walking parameters, functional lower extremity performance evaluation and balance evaluation.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Evaluation of muscle activation	In our study, muscle activations of the tibialis anterior, peroneus longus and abductor hallucis muscles both during maximum isometric contraction and during walking will be evaluated by a trained and experienced researcher using the sEMG device.	Change from baseline muscle activation at 8 weeks
Secondary	Y balance test (YBT):	There are 3 bars of 1.5 meters long fixed to a 2.54 cm high central foot plate at an angle of 135 and 90 degrees between them. It is asked to lie down with the tip of the toe in 3 directions and the measurements are recorded.	Just before the training and at the end of 8-week training
Secondary	Vertical jump, flight time	Vertical jumping and jumping on one foot will be evaluated with MicroGate Opto-jump Next®. With this test, flight time will be measured during vertical jump, and it will be recorded by seconds.	Just before the training and at the end of 8-week training
Secondary	Vertical jump, jump height	Vertical jumping and jumping on one foot will be evaluated with MicroGate Opto-jump Next®. Jump height wil be recorded by centimeters.	Just before the training and at the end of 8-week training
Secondary	Vertical jump, power	Vertical jumping and jumping on one foot will be evaluated with MicroGate Opto-jump Next®. Power will be recorded by watt/kilogram.	Just before the training and at the end of 8-week training
