HYPOTHESIS

THERE WILL BE MORE ADVANTAGES FOR A PROSTHETIC LEG USING A KNEE RATHER THAN ONE WITHOUT.

APPARATUS

MATERIALS USED

• Adaptive Brand Prosthetic Leg
• Locking Knee Brace (Typically Used for Surgery Patients)
• Infinity Prosthetic Knee

PROCEDURE

PROCEDURE

• I set up a range of 3 yards.
• I walked the distance at normal pace for a control.
• I walked the prosthetic leg without the brace alongside my own leg to simulate real movement.
• I put the brace on the knee and locked it, simulating a prosthetic with no knee. Then repeated the same process.

RESULTS

BIBLICAL ABSTRACT

""So God created man in His own image, in the image of God created He him; male and female created He them.""
Genesis 1:27
Since humans are the creations of God, then one might argue that to change or alter that creation is trespassing on divine territory. As a Christian, I think that it is acceptable to use prosthetics because one is not altering or damaging His creation. God created us in His perfect image and I think it is amazing that we have the advanced technology today to restore a limb to the likeness of that designed by God.

CONCLUSION

A prosthetic leg with no knee seems to have more unsatisfactory qualities. The results of the experiments show that there are more pros to having a knee on ones prosthetic leg. Still, some people opt to have no knee, so they aren't completely unusable.
