There are four different types of artificial limbs. Here is a presentation that elaborates on these, and talks about some of the challenges amputees will face with these different types of prosthesics.
2. Transradial
Prosthesis
• An artificial limb that replaces an arm
missing below the elbow!
• Two types available: cable-operated
limbs and myoelectric arms!
• Cable operated limbs work by attaching
a harness and cable around the
opposite shoulder of the damaged arm!
• Myoelectric arms work by sensing with
electrodes when the muscles in the
upper arm moves, causing an artificial
hand to open or close
3. Transhumeral
Prosthesis
• An artificial limb that replaces an
arm missing above the elbow!
• The complexities around moving
the elbow makes mimicking the
correct motion with an artificial
limb very difficult
4. Transtibial
Prosthesis
• An artificial limb that
replaces a leg
missing below the
knee!
• Amputees can often
regain normal
movement more
readily than someone
with a transfemoral
amputation, since
retaining the knee
makes movement
easier
5. Transfemoral
Prosthesis
• An artificial limb that replaces a leg
missing above the knee!
• The lack of knee makes it hard for
amputees to regain normal
movement!
• Transfemoral amputees generally
need to use approximately 80%
more energy to walk than a person
with two whole legs!
• Newer and more improved designs
allow more control for the user
