 Aims and background: The purpose of this study was to compare the parameters of ground reaction force during landing in patients with chronic low back pain. Material and Methods: 21 healthy men and 21 men with chronic low back pain participated in this study. Using a Kistler force plate )1000Hz) GRF during landing was measured. Then, maximum GRF and their related time-to-peak, impulse and loading rate were obtained. Independent t student was used to analyze the data (α=0.05). Findings: People with chronic low back pain have lower internal-external GRF and have a lower vertical GRF to touching the ground )FZ2) when landing compared to healthy people. Patients with chronic low back pain have a lower loading rate(Y)(P=.049). conclusion: People with low back pain have a higher vertical ground reaction force than healthy people, and these factors are considered as a risk factor for increasing compressive forces to the spine.
