简要总结
Amputation is a problem that can be encountered for many reasons, can cause functional disability in varying severities and puts a multifaceted financial burden on individuals, society, and states. The phantom feeling is the state of the sensory sensation of a limb that does not already exist and is observed in various forms in individuals with amputation.
The aim of this project is to investigate whether the phantom sensation affects autocorrelation of gait in unilateral amputated individuals and thus to determine whether the phantom sensation is a functional sensation that affects the multifaceted nature of gait. In addition, the measurement of whether phantom sensation contributes to the ability of amputees to adapt to changing conditions and obtaining a unique calculation method that determines autocorrelation are other specific aspects of the study. The study will be conducted on individuals with unilateral traumatic transtibial amputation who have acceptable phantom sensation, individuals with no-phantom sensation and healthy individuals. Individuals who meet the inclusion criteria will be included in the gait assessment. During the evaluation, at least 512 consecutive steps will be collected from each individual when walking on the treadmill at their preferred speed. The walk test will then be repeated on the perturbation treadmill of 5-10%. It will be determined whether the gait characteristics obtained by gait analysis show autocorrelation by using signal processing methods.

主要结局
Gait Analysis on Flat Ground
时间窗: 5 minutes after the protocol for determining the preferred walking speed
In order to collect the data required for the autocorrelation calculation in flat walking, the subject will be placed on the treadmill (REAX RUN) and he or she will be asked to continue his walking at the "preferred speed" level obtained with the previous protocol, until at least 512 steps are collected. This walk is expected to take 3-4 minutes in total. After a sufficient number of steps is reached, the treadmill will be gradually slowed down and stopped. Afterward, the individual will be taken to rest again.
Gait analysis on Perturbed Ground
时间窗: 5 minutes after walking on the flat ground
After the resting period is terminated, the individual will start walking at the speed determined according to the Hinton protocol on the treadmill (REAX RUN) for gait analysis again. During the second walk, 5-10% perturbation will be given on the treadmill until 512 steps are collected. The autocorrelation analysis to be performed with the data taken during walking on the perturbed ground will measure the adaptability of the individual's gait to changing conditions. The data of the walk will be automatically saved on the system computer. Whether the autocorrelation feature of the gait is observed or not will be calculated mathematically using signal processing methods.
