Functional testing of elderly subjects after lower limb amputation

The aim of the present study was to find out if it is possible to use the same functional tests for elderly subjects after lower limb amputation who live independently at their homes as for healthy ones. Will these tests discriminate among different problems in subjects with different levels and different causes of amputation and will they discriminate between active and sedentary subjects? The study examined 83 volunteers who lived independently at their homes (55 healthy sedentary, 17 after trans-tibial amputation, 11 after trans-femoral amputation). All subjects were aged 60 or older. All subjects after lower limb amputation were found to have significantly worse results in almost all tests in comparison with the healthy sedentary men. The subjects after transfemoral amputation needed significantly more time at the "up and go" test, walked a shorter distance in 9 minutes, and performed fewer stand-ups from a chair and fewer steps in two minutes than the subjects after trans-tibial amputation. The active subjects after lower limb amputation had better balance, were quicker at the "up and go" test and walked longer in a minute than the sedentary subjects after lower limb amputation. It can be concluded that this test battery can also be used to test subjects after lower limb amputation because it discriminates among different severity of problems in subjects with different level and cause of amputation as well as between active and sedentary ones.
