The main objective of this study was to examine the thoracolumbar fascia thickness in chronic stroke patients using objective methods and to reveal the relationship of this flexibility with balance, trunk control, trunk flexibility, functional independence and other relevant clinical parameters. Demographic information will be recorded and evaluated. Thoracolumbar fascia thickness will be assessed for individuals in both groups using ultrasonography, trunk flexibility using the Sit-and-Reach test, trunk function using the Trunk Impairment Scale, balance using the Functional Reach Test and the Timed Up and Go test, and functional independence using the Functional Independence Scale.
