AK Suspension Methods Flashcards
Skin-Fit Suction
Indication:
-whenever clinically possible
-mature limb
Advantage:
-increased proprioception
Limitations:
-susceptible to volume change
-difficult to don
-limited absorption of shear and impact forces
Gel liner with locking or lanyard
Indication:
-firm limb
-expected volume changes
Advantages:
-easy to don
-secure suspension
-allows for volume changes
-absorption of shear and impact forces
Limitations:
-distal distraction can lead to edema
-requires hand dexterity for donning
-requires consideration of alignment and build height
Gel liner with seal
Indications:
-firm limb
-expected volume changes
Advantages:
-easy to don
