Term
| Relaxed Calcaneal Stance Position (RCSP) |
|
Definition
position of STJ (calcaneus) when patient is fully compensated in midstance
normal is 2 degrees varus to 2 degrees valgus |
|
|
Term
| Neutral Calcaneal Stance Position (NCSP) |
|
Definition
| position of STJ (calcaneus) when patient is placed in neutral position while standing |
|
|
Term
| Tibial Stance Position (Tibial Influence) |
|
Definition
bisection of tibia in relation to the ground while in NCSP
normal - tibia in 0-4 degrees varus
can add this value to STJ neutral to find NCSP |
