🗑
|
||||
| Second Class Lever | Force and resistance are on the same side of the axis.
🗑
|
||||
| Third Class Lever | Force and Resistance are on the same side of the axis, but force acts between the axis and resistance.
🗑
|
||||
| Rearfoot Varus | Causes rigid rearfoot
🗑
|
||||
| Forefoot Valgus | During Gait, the 1st MT strikes prematurely causing eversion and supination of the forefoot
🗑
|
