CMP FEET Flashcards
1
Q
Single axis
A
Simplicity
Limited ambulation or max durability required
Inexpensive and durable
Rigid forefoot: not energy efficient
2
Q
SACH
A
Rapid foot flat
Enhance knee stability
Biomechanical stability in early stance
Abrupt DF stop increases knee hyperextension moment
Disadvantage: increased weight, maintenance initial cost, no energy efficient
3
Q
Multi axial
A
Hindfoot inversion/eversion Internal/external rotation Accommodate uneven surfaces Reduces stress on skin and px Dis: increased weight, maintenance, initial cost
4
Q
Flexible-keel
A
