anatomy

the more proximal an amputation is, the more extreme it is; it’s going to be tougher to get full function

  • AKA, above the knee (transfemoral)

    • maintaining the function of the knee is very helpful for function + prosthetics

    • having a prosthetic that also has to have a synthetic knee is more complicated and difficult, making an AKA less preferable

  • BKA, below the knee (transtibial)

positioning: wheelchair safety

legs shift your center of gravity (COG) forward, allowing you to do leans; someone with a LE amputation will not have this front-weight, making their COG shifted back

  • a person with an amputation leaning back (outside their base of support) is more at risk for falling

    • to address tipping risk…

      • anti-tippers

        • extensions off the chair that have little wheels/bumpers that will hit the ground and prevent tipping when someone leans out of their COG

      • shift COG forward

        • using some sort of cushion, so that a person is sitting more forward, shifting their COG forward as well

        • or, manually adapt the chair so that the either…to make sure COG is further away from the back wheel

          • back wheel is further back or

          • chair part is further forward

positioning: limb positioning

risk of flexion contracture, so we want to promote knee extension

  • —> residual limb support
