Firstly, For individuals with low back pain, all measurements will be evaluated without wearing any orthosis. The waist circumference of individuals with low back pain will be measured and the orthosis was adapted to the appropriate orthosis size by the prosthetist orthotist. After waiting with the orthosis for half an hour, the measurements will be repeated. Then, the person will be asked to wear the orthosis without any intervention.

A Visual Analogue Scale (VAS) is one of the pain rating scales used for the first time in 1921 by Hayes and Patterson[1]. It is often used in epidemiologic and clinical research to measure the intensity or frequency of various symptoms. For example, the amount of pain that a patient feels ranges across a continuum from none to an extreme amount of pain. From the patient's perspective, this spectrum appears continuous; their pain does not take discrete jumps, as a categorization of none, mild, moderate and severe would suggest. It was to capture this idea of an underlying continuum that the VAS was devised

An orthosis comfort score, which is valid and reliable and developed from the socket comfort score, will be used to evaluate comfort. The score measures the comfort felt by the patient between values of 0 and 10. "How would you rate the comfort of the orthosis?" They are expected to answer the question as 0 is the most uncomfortable orthosis and 10 is the most comfortable orthosis.

Functional Reach Test (FRT) is a assessment tool for ascertaining dynamic balance in in simple task. In standing, measures the distance between the length of an outstretched arm in a maximal forward reach, while maintaining a fixed base of support. This information is correlated with risk of falling.

Foot plantar pressure distribution (static pedobarographic) analyzes and postural stability parameters will be performed through a computer-aided data collection and display system. Sensor Medica (Rome, Italy) Pedobarography Device, which has a pressure-sensitive platform connected to the computer and a software system that records and analyzes the data. Measurements will be made for individuals with low back pain.
