How do ankle sprains affect ROM? |
Very little loss of ROM |
|
What type of arch do pronators have? |
Pes planus (flat) |
|

|
Why do supinators typically experience more ankle pain? |
Supination is more rigid |
|
Why do pronators typically experience less pain? |
Foot deform during weight bearing thereby absorbing smaller force of longer duration than if it were rigid |
