Biomechanical and walking fases

 

 



PODOLOGY


Podology is the science in the health area, that studies prevent diagnoses and heal foot pathologies, both in static or dynamic, as well as his repercussions in human body.



ERGONOMIE


Ergonomie studies the functional characteristics for a good and healthy working environment and for the equipment used by the worker, providing more comfort, security, efficiency and productivity.



THE FOOT

The locomotion organ, the basis of support of all the human body, the foot contributes significantly to the performance of all inferior members, in the same way the inferior members contributes themselves for good performance of the foot.

Anatomically consist of bones, joints, muscle, ligaments, tendons, blood vessel, cellular tissue and skin. In this way we can define the foot as a solid but flexible structure, that on the other side it supports all human body weight, and has to adapt to all different situations that the individual faces across is life.

A badly adapted shoe can be a torture for the wearer, affecting the morphological and∨ structural alterations of the foot.

 



BIOMECHANICAL OF THE FOOT

 



This is the application of the mechanical laws to living systems, in specific consideration for the human locomotion and that includes mechanical laws that rule the structure, function and position of the human body. The adaptation of biomechanical to Podology is important for the comprehension of foot performance.



The changes to the normal biomechanical of the foot may cause some deformations in ankle, knees, hip, vertebral column, superior members and also the head.
The way each individual walks depends on several factors such as age, sex, weight, professional activity, physical and mental conditions, location social position, joint morphology, ligaments, muscles and finally the footwear. Beyond being comfortable, a good pair of shoes must allow the normal movements, contributing to keep the foot in good condition.

 

 



 

The biomechanical of the foot allows the walking movement, either in the OSCILATION PHASE or SUPORT PHASE:  


- Heel shock
- Total support of the foot
- Coming off



It is necessary that the footwear makes use of liberty of movement essentially in the zone of the ankle and MTF.

 

 

 

 WORKING FOOTWEAR



Depending on he work involved, the foot is submited to varous types of external aggressions such as:


- Shock
- Fall of objects
- Perforation
- Risk of high temperatures

 The main function of the footwear is to provide:


- Security, diminishing (reducing) the risks of injuries of the foot
- Protection

It must be held in account four aspects under the biomechanic point of view:


- Adaptation of the footwear to the form and dimensions of the foot;
- Adaptation of the footwear to the physiological movements of the foot;
- Capacity of dumping of loads derived from the contact of the foot with the ground;
- Characteristics of the anti-slip between the footwear and ground surface.

 

 

THE RESULT OF HIGH HEELS

 



The use of too high heels forces the body to transfer its weight to the bone metatarsal, creating an extreme effort in the intermediate bones and toes, which originates cramps in the muscles and also the leg does not relax.

 


The inferior menbers suffer a static modification, the hip and the spine suffer distortions originating an incorrect positio
