It is a scale that objectively evaluates the level of independence of lower extremity amputees with their prostheses. The scale parallels the Medicare Functional K Classification System. A Houghton Scale score ≥ 9 corresponds to a level K3 or K4 amputee, Houghton Scale scores 6-8 correspond to a level K2 amputee, and a Houghton Scale score ≤ 5 corresponds to a level K1 amputee. The Houghton scale is a scale scored between 0-12.

It is one of the tests that measures speed and agility abilities together. It measures the daily walking ability of older adults with mobility impairments (8). 8ŞYT tests a participant's walking on both straight and curved paths. It uses a path in which the participant is asked to walk in a figure eight around two cones. Scores are recorded in two areas: speed (time to complete), amplitude (number of steps taken).

The presence of limitation will be evaluated by checking the normal joint movements of the amputees, and whether there is an effect on the ROM values during the use of the prosthesis will be taken into account. Joint range of motion of amputees will be evaluated using the Goniometer-Pro smartphone application.

Joint range of motion will be measured based on reference and pivot points in supine and prone positions. Measurements will be taken on both sides and noted. In unilateral transtibial amputee; Range of motion in knee joint flexion, extension, hip joint flexion, extension and trunk flexion, extension and lateral flexion will be checked. In unilateral transfemoral amputee; Hip joint flexion, extension and trunk flexion, extension, lateral flexion range of motion will be measured based on standing reference and pivot points. Measurements will be taken on both sides and noted.

With this test, joint position sense, which is a component of proprioception, will be measured. Joint position sense is a person's ability to perceive the position sense of a joint and restore it when the position of the extremity is changed. The most well-known tests in the evaluation of proprioception measure the person's capacity to actively or passively perform a targeted joint position (active/passive repositioning test) or the threshold of perceiving the desired joint movement (movement detection threshold test).

It is a performance-based measure that can be used to evaluate physical function, including dynamic balance ability. The test is a modification of the "Timed Up and Go" test. The L-test allows evaluation of walking over a longer walking distance and involves turning in two directions. Amputees have a 1-minute rest period between trials and a 2-minute rest period between measurements. Amputees are instructed to walk at comfortable walking speeds, with or without their usual walking aids. Before participation, a standard demonstration and explanation of both outcome measures is given. In order to perform the test; 1 stopwatch, 1 chair, 3 meters and 7 meters long walking area are required.

It is a test that evaluates the walking performance of an amputee. This test is a performance test used to evaluate walking speed over a short distance in meters per second. The equipment required for the test is a stopwatch and a ground with a specified distance. Total time for scoring is recorded in meters/second. An individual assistive device may be used, but must be kept consistent and documented for each test. Three trials are made and the average of these three trials is taken. Patients are asked to walk a distance of 10 meters in a straight line on a flat road, at their own pace, using assistive walking devices, if any.
