This study aims to evaluate the effectiveness of specific foot mobility techniques on functional and biomechanical parameters of the foot in young adults aged 18 to 24 years. The study employs a randomized controlled trial design with the following key components:

Key outcomes include:

Baropodometric pressures (measured using a baropodometric platform). Balance (evaluated through the Y-Balance Test). Navicular height (assessed using the Navicular Drop Test) Anterior functional reach (measured through functional reach test)

This study explores the immediate and short-term effects of specific foot mobility techniques on functional and biomechanical outcomes in healthy young adults. The research is grounded in the growing recognition of the foot's critical role in postural control, balance, and lower-limb biomechanics.

The intervention consists of foot mobility techniques designed to improve joint mobility and overall foot function. These techniques will be applied bilaterally. The study employs a randomized controlled trial design, with participants randomly allocated to either the experimental group (receiving the intervention) or the control group (receiving no treatment during the intervention period).

Participants are assessed at three time points:

Baseline (M0): Before the intervention. Immediately Post-Intervention (M1). Follow-Up (M2): 24 hours after the intervention.

The primary outcomes include:

Changes in plantar pressure distribution and postural control as measured by a baropodometric platform.

Balance performance assessed through the Y-Balance Test. Navicular height variation evaluated using the Navicular Drop Test. Anterior functional reach, measured by Functional Reach Test. The study focuses on identifying measurable improvements in functional and biomechanical parameters that may enhance clinical approaches to foot health and rehabilitation. By targeting a young and healthy population, the research aims to establish a foundation for further studies in other age groups and clinical conditions. This work aims to contribute to evidence-based practices in manual therapy and foot biomechanics.

Inclusion Criteria:

eciding whether to share Individual Participant Data (IPD) involves weighing several considerations... we have to further reflect to make an informed decision about sharing IPD, balancing the potential benefits to the scientific community with the responsibility to protect participant rights and data integrity.
