Dynamic Alignment: Swing Resistance
Flexion Resistance:
a) Initial adjustments are factory set (Extension 2, Flexion 4)
b) Observe the amputee walking
c) If there is excessive heel rise: Increase resistance

Extension Resistance:
a) Observe the amputee
walking
b) If there is excessive
terminal impact on knee
extension:
Increase resistance
c) If the knee does not extend
satisfactorily:
Decrease resistance
NB: As a 'rule of thumb'
exceed extension resistance
