NAVICULAR DROP AND LOWER EXTREMITY BIOMECHANICS

November 4, 2026 updated by: Gönül Elpeze, Gaziantep Islam Science and Technology University

THE EFFECT OF EXERCISES ON LOWER EXTREMITY BIOMECHANICS IN INDIVIDUALS WITH PES PLANUS

The purpose of this study is to examine the effects of an exercise program on lower extremity biomechanics in individuals with pes planus. Participants who meet the inclusion criteria and are assessed using the Navicular Drop Test will be divided into two groups: a control group and an experimental group. The control group will perform short-foot exercises, towel-curl exercises, and stretching exercises. In addition to these, the experimental group will perform ankle-strengthening exercises using elastic bands. All exercises will be conducted 3 days a week for 4 weeks, consisting of 3 sets of 10 repetitions each. The lower extremity biomechanical alignment and functional status of the participants will be evaluated before and after the 4-week intervention using the Navicular Drop Test, Q-angle measurement, and pelvic inclination angle measurement.

Arms and Interventions

Participant Group / Arm
Intervention / Treatment
Experimental: Control Group

Participants will receive a standard exercise program aimed at improving foot posture and arch support.
Other: Standard Exercise Program

Participants in the control group will perform short foot exercises, towel curl exercises, and lower extremity stretching exercises. The protocol will be administered 3 days a week for 4 weeks, with each exercise performed in 3 sets of 10 repetitions.
Active Comparator: Experimental Group

Participants will receive the standard exercise program combined with targeted ankle strengthening exercises to enhance lower extremity biomechanics.
Other: Standard Exercise Program

Participants in the control group will perform short foot exercises, towel curl exercises, and lower extremity stretching exercises. The protocol will be administered 3 days a week for 4 weeks, with each exercise performed in 3 sets of 10 repetitions.

Other: Ankle Strengthening Exercise Program

Participants in the experimental group will perform ankle strengthening exercises using elastic resistance bands, administered 3 days a week for 4 weeks with 3 sets of 10 repetitions.

What is the study measuring?

Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Navicular Drop Test
Time Frame: Baseline and 4 weeks

Measurement of the change in navicular height from sitting to standing position to evaluate medial longitudinal arch mobility and pronation in millimeters.
Baseline and 4 weeks
Q Angle
Time Frame: Baseline and 4 weeks

Measurement of the angle formed by a line from the anterior superior iliac spine to the central point of the patella and another line from the central point of the patella to the tibial tuberosity in degrees.
Baseline and 4 weeks
Pelvic Inclination Angle
Time Frame: Baseline and 4 weeks

Measurement of pelvic alignment using an inclinometer to evaluate the angle between the horizontal plane and the line connecting the anterior superior iliac spine and posterior superior iliac spine in degrees.
Baseline and 4 weeks
