Effect of Thoracic Kyphosis and Lumbar Lordosis on the Distribution of Ground Reaction Forces on the Feet.

INTRODUCTION

In clinical practice, foot load receptors are very important in shaping the correct vertical posture and optimal equilibrium reactions. They are so important that stimulating them gives measurable effects in improving both balance and posture. Plantar pressure distribution is an important parameter that provides information on changes in a person's posture, also during gait.

AIM: The aim of the work is to assess the effect of thoracic kyphosis and lumbar lordosis on the distribution of ground reaction forces on the feet.

MATERIALS AND

METHODS

A total of 211 subjects aged 8-12 were examined. Body posture and distribution of ground reaction forces on the feet were assessed using the following parameters: thoracic kyphosis angle, lumbar lordosis angle, maximum pressure (static), average pressure (static), foot surface, distribution of foot pressure, maximum pressure (dynamic), time load (dynamic). DIERS formetric and DIERS pedoscan methods were used to measure the parameters.

RESULTS

The level of the kyphosis angle correlated positively with the percentage distribution of forefoot load in static conditions. The level of lordosis angle correlated positively with the foot surface and forefoot load. Positive correlation of the lordosis angle is also related to its connection with the difference in leg load during gait. A broader cause and effect view of body posture defects and the distribution of ground reaction forces on the feet can affect a more complete assessment of the correlation between these variables, contributing to more effective treatment of any disorders of the described phenomena.

CONCLUSION

The size of thoracic kyphosis and lumbar lordosis affects the distribution of ground reaction forces on the feet. The effect of lumbar lordosis has a linear value in relation to percentage distribution of forefoot and heel loads.
