Purpose: Low back pain is one of the most common health problems of the world. Very different causes can cause back pain. Approximately 85% of people who are examined for low back pain the cause is not specific. The purpose of this study is to investigate the effects of the knee abnormalities on pain intensity and functional fitness in middle aged men with the chronic nonspecific low back pain. Method: The statistical community of this study includes 30 people of patient’s male with nonspecific chronic low back pain in the age range of 30-50 years with one of the abnormalities of genu varum or genu valgum. Results: The research findings were analyzed using descriptive and inferential statistical methods (dependent t and independent t tests). The research findings indicate that both the pain and disability of the experimental groups have significantly decreased after applying selected of corrective programs (Stretching muscles and short elements and strengthening weakened muscles). Sitting frog, walking with the inner edges of the legs, pressure to enter the wall with the outer edges of the legs to modify the genu varum. passing legs from one side to another in the form of scissors in liner mode, passing the medicine ball to the wall with the inside of the legs, walking with the outer edges of the legs to modify the genu valgum (p<0.05). While the two variables in the control group did not differ significantly (p>0.05). Conclusions: According to the results and considering the conditions prevailing on the research samples, it can be concluded that knee abnormalities (genu varum and genu valgum) affected by pain intensity and functional fitness efficacy in nonspecific chronic low back pain patients and Corrective exercises of these abnormalities has had a significant effect on reduce pain and disability index.

Background: Shoulder impingement syndrome is a common complication that causes pain and disability, functional limitations and reduced quality of life. This syndrome is usually seen in people who are involved in activities and sports involving rotating movements above the head, including bodybuilders. Meanwhile, corrective exercises have been considered as an intervention in the rehabilitation of the condition. Exercises based on National Academy of Sports Medicine (NASM) principles are known as one of the new methods in the rehabilitation and prevention of sports injuries.Aim: The purpose of this study was to investigate the effect and permanence of corrective exercises on pain intensity, functional disability and kinematic parameters of bodybuilders with shoulder impingement syndrome.Materials and Methods: In this semi-experimental research with a pre-test-post-test design, 20 male bodybuilders with shoulder impingement syndrome were randomly assigned in two groups; corrective exercises as the experimental group (n=10) and control group (n=10). Visual Analog Scale (VAS) questionnaire was used for pain intensity. Disabilities of the Arm, Shoulder, and Hand (DASH) questionnaire was used for functional disability. Kinovea software was used to kinematic parameters. The evaluations carried out during three stages: the pre-test, the first post-test (after 8 weeks) and the second post-test (after 12 weeks). Data were analyzed using descriptive statistics, repeated measures analysis of variance (ANOVA) at a significance level of 0.05 using SPSS version 20 software.Results: The findings showed that after 8 weeks of corrective exercises, there were significant changes in pain intensity and functional disability in the experimental group (P<0.05). Also, significant changes in shoulder biomechanical parameters during flexion, abduction, external rotation and internal rotation movements were observed between the two groups (P<0.05). Permanence of the exercises in the studied variables after 12 weeks showed a significant difference between the two groups (P<0.05).Conclusion: According to the obtained results, it can be stated that a course of NASM exercises reduced shoulder pain, improved functional disability and improved kinematic parameters in male bodybuilders with shoulder impingement syndrome.
