Individuals participating in the study will first be divided into two groups by randomization. While IASTM (Instrument Assisted Soft Tissue Mobilization Techniques) will be applied to one group in the prone position, IASTM will be applied to the other group with functional exercise. The pain, mobility, flexibility, disability and endurance parameters of the individuals assigned to the groups after randomization will be determined just before the application, immediately after the 1st application and immediately after the 6th application. The study will last for a total of 6 sessions, with two sessions per week for 3 weeks.
The aim of this study is to determine whether the effectiveness of instrument-assisted soft tissue mobilization technique is different from passive prone lying when performed with a functional exercise in individuals with chronic nonspecific low back pain.
