Correlation between Levels of Physical Activity and Foot Pressure Distribution in Asymptomatic Individuals: A...

The relationship between physical activity levels and plantar pressure distribution has not been extensively studied in asymptomatic adults, particularly within the South Asian population. Understanding these correlations will help prevent foot pathologies and develop targeted interventions.

To investigate the correlation between levels of physical activity, as measured by the International Physical Activity Questionnaire (IPAQ), and static and dynamic foot pressure distribution in healthy, asymptomatic adults.

This prospective cross-sectional study included 200 asymptomatic participants (aged 18-60 years) at a tertiary care center. Participants were categorized into low, moderate, and high physical activity groups based on the IPAQ scores. Plantar pressure distribution was measured using the BTS P-WALK system during standing as well as walking. Peak pressures across ten anatomical foot regions were recorded and analyzed using appropriate statistical methods.

Static analysis revealed significantly higher peak pressures under the toes (T1 and T2-5) in the high activity group, particularly on the right foot. The midfoot region showed higher pressure in the low-activity group. The moderate activity group had the highest pressure over the forefoot and hindfoot, while individuals with high physical activity had the lowest overall dynamic plantar pressures.

These findings emphasize the biomechanical adaptations associated with varying activity levels and underscore the need for personalized physical activity and footwear recommendations.
