The effect of movement pattern training on the range of motion of the knee joint in the frontal level in athletes with nonspecific chronic low back pain during sing-leg landing: A randomized clinical trial

Low back pain is one of the most common musculoskeletal disorders in athletics. The aim of this study was to determine the effect of Movement-Pattern Training on the range of motion of the knee joint in the frontal level in athletes with nonspecific chronic low back pain during sing-leg landing.

This clinical trial was carried out in University of Mohaghegh Ardabili at 2018. Firstly, 30 males with non-specific chronic low back pain were selected with available sampling and then they randomly divided into control (15 subjects) and experimental (15 subjects) groups. Tests were done in the form of pre and post-tests. Movement pattern exercises were performed on experimental group over a 6-week period. Ethically, the training protocol was done on waiting control group after post-test. Post hok Co-variance was used for statistical analysis of data.

The results showed that movement pattern training reduces the range of motion of the knee joint in the frontal level of patients with non-specific chronic low back pain (P=0.000, d=3.94 high effect size).

The results of the study showed that the exercises of the movement pattern have caused significant changes in the range of motion of the knee joint at the frontal level. that could be beneficial for future researches in order to prevent and treat the low back pain individuals.
