| Biomechanics |
The study of how forces affect the human body. Body mechanics
and function. |
| External rotation |
Outward rotation. |
| Internal rotation |
Inward rotation. |
| Instability |
Lack of steadiness and efficiency. |
| Neutral position |
The 'central' position of the foot whereby there is no pronation
or supination occurring. This is generally the most efficient
foot position. |
| Polypropylene |
Thermopolymer used in the manufacture of foot orthoses. |
| Pronation |
The rolling inwards of the foot including lowering of the arch
and inward tilting of the heel. The pronated foot is generally
an unstable and inefficient foot type, prone to injury. |
| Supination |
The rolling outwards of the foot. This foot is high arched, lacks
flexibility and is a poor shock absorber. |
| Symptoms |
Any abnormality of function, structure or sensation as experienced
by a person. |
| Varus |
Tilted towards the outside of the body. |
