Summary

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.

Determining Preferred Walking Speed

In the beginning, sensors of the gait analysis system (RehaGait®), which can record the time-distance characteristics of consecutive multiple steps (step length, step width, double step length, and timing information, etc.) will be installed. The 7 sensors of this system are attached to the shoes of the individual, proximal to the ankle, distal thigh, and sacroiliac joint level (Aminian et al., 2014). Individuals will be required to wear casual athletic shoes and comfortable, non-knee-covering shorts. Next; Each individual will walk freely on the treadmill at their own pace. To find the preferred walking speed of the individual, Hinton et al. protocol will be used (Hinton et al., 2018). The speed of the treadmill will be increased or decreased in line with the direction of the participants. After being determined according to the protocol, the individual will practice walking at this speed for 4-5 minutes. The individual will rest as much as he or she wants.
