Overview

The goal of this observational study is to examine the relationship between plantar flexor endurance and postural and tibial sway in adults (≥18 years) with pes planus (flatfoot). The main questions it aims to answer are: Is there a correlation between plantar flexor endurance, postural sway and tibial sway during single-leg stance? Participants will: Perform a heel rise test to assess plantar flexor endurance Stand on one leg while wearing a motion sensor to measure postural and tibial sway Complete the tests under both eyes-open and eyes-closed conditions

Study Type

OBSERVATIONAL

Enrollment

Conditions

Pes Planus

Interventions

Heel rise test and postural/tibial sway measurementOTHER

Participants undergo a heel rise test to assess plantar flexor muscle endurance. Postural and tibial sway are measured during single-leg stance using a wearable sensor under eyes-open and eyes-closed conditions. No therapeutic intervention is applied.

Outcomes

Primary Outcomes

Plantar flexor endurance measured by heel rise test

The number of repetitions participants can perform during the heel rise test, assessing the endurance of the plantar flexor muscles. Participants stood on one leg and raised their heels in time with a metronome set at 40 beats per minute. The test ended when the participant was fatigued or unable to continue, and the number of heel rises completed was recorded. The test was performed on both lower limbs.

Time frame: Measured once at baseline during the study visit.

Secondary Outcomes

Postural sway during single-leg stance

Postural sway was assessed using the Alda Balance Gear wearable sensor. Sensor was assessed for medio-lateral (ML) and antero-posterior (AP) sway. The sensor was placed at the L3-L5 vertebral level using a belt device. Participants performed a single-leg stance for up to 30 seconds under eyes-open (EO) and eyes-closed (EC) conditions. The test ended if balance was lost and the foot touched the ground. Postural sway was recorded only on the dominant limb.

Time frame: Measured once at baseline during the study visit.

Tibial sway during single-leg stance

Tibial sway was assessed using the Alda Balance Gear wearable sensor. Sensor was assessed AP and ML sway. The sensor was placed one-third distal on the lower leg. Participants performed a single-leg stance for up to 30 seconds under eyes-open (EO) and eyes-closed (EC) conditions. The test ended if balance was lost and the foot touched the ground. Tibial sway was measured on both lower limbs.

Time frame: Measured once at baseline during the study visit.
