About this study

Our study, B.A.İ.B.Ü. İzzet Baysal Physical Therapy Training and Research Hospital and Fizyotermal Corp. It will be carried out as a dual center on individuals between the ages of 18-45 who apply to our clinic. It will be carried out by selecting 48 people who are suitable for the study among the flat-footed patients who applied to the clinics.

Patients will be evaluated before they start using the insoles, and immediately after using it , also after wearing the insoles for 8 weeks.

Patients will be randomized according to the order of their arrival at the clinic.

Treatment and study plan

ICB Medical Insoles

Other

After the foot analysis of the participants in the intervention group, special insoles will be designed in a computer program. In these insoles, 3-6 mm medial wedge support, 1-3 mm heel wedge support, 2-4 mm medial longitudinal arch support will be provided. These values will be determined according to the needs of each participant. A single physiotherapist will design all insoles. All drawings will be made by a single physiotherapist. After the design of the insoles is completed, insoles will be produced by transferring them to a Computer Numerical Control (CNC) machine. Ethyl vinyl acetate (EVA), the use of which has been found useful before, will be used as the material in the insoles molds. After processing, 1mm thick fabric will be used for the top coating. All insoles will be produced by the same physiotherapist.

ICM Insoles

Other

As in the intervention group, insoles will be designed for the participants in the control group, processed by CNC machine and the production will be completed. Only 2mm medial longitudinal arch support will be given to the insoles of the people in this group.

Primary outcomes

  1. The Physical Activity Assessment Questionnaire (IPAQ) Short Form

    Time frame: Eight weeks

    This form will be used to measure physical activity levels. comprises a set of 4 questionnaires.

    Long (5 activity domains asked independently) and short (4 generic items) versions for use by either telephone or self-administered methods are available. The purpose of the questionnaires is to provide common instruments that can be used to obtain internationally comparable data on health-related physical activity. Higher scores indicates better physical activity level.

  2. Flamingo Balance Test and Y Balance Test

    Time frame: Eight weeks

    This will be applied for balance evaluation.To assess the ability to balance successfully on a single leg. A stopwatch, metal beam 50cm long, 5cm high and 3cm wide needed for test procedure. The total number of falls or loss of balance in 60 seconds is recorded. Scoring tables are available in the Eurofit Manual.

Secondary outcomes

  1. Standing Long Jump Test

    Time frame: Eight weeks

    For functional performance Standing Long Jump test will be applied.The athlete stands behind a line marked on the ground with feet slightly apart. A two foot take¬off and landing is used, with swinging of the arms and bending of the knees to provide forward drive. The subject attempts to jump as far as possible, landing on both feet without falling backwards. Three attempts are allowed. The measurement is taken from take¬off line to the nearest point of contact on the landing (back of the heels). Record the longest distance jumped, the best of three attempts. The table below gives a rating scale for the standing long jump test for adults, based on personal experiences.

  2. 10 Meter Walk Test

    Time frame: Eight weeks

    For functional performance10 Meter Walk test will be applied. Patient's will be asked to walk 10 meter. Time is measured while patients walk.

  3. Shuttle Running Test

    Time frame: Eight weeks

    For functional performance Shuttle Running Test will be applied. his test requires the person to run back and forth between two parallel lines as fast as possible. Set up two lines of cones 30 feet apart or use line markings, and place two blocks of wood or a similar object behind one of the lines.Two or more trails may be performed, and the quickest time is recorded. Results are recorded to the nearest tenth of a second.
