Objective: The aim of this study was to determine the effect of twelve weeks of manual therapy on pain and range of motion in women with chronic non-specific back pain.
Method: In this clinical trial study, 50 women between 25 and 65 years old with chronic non-specialized low back pain were randomly selected and divided into two experimental groups of manual therapy with mean age (28.15 ±7.00), weight ( 60.00±8.11), height (165.18 ±7.60) and a control group with mean age (40 ± 15.00), weight (60±9.00), height (160±8.00) were divided. The control group was given only low back pain training program and the experimental group received manual treatment for 12 weeks and 1 session per week. The variableswere measured in two stages of pre-test and post-test. In order to analyze the differences within the group, paired t-test and one-way analysis of variance were used to examine the differences between the groups.
Results: The results showed that training intervention was effective in improving pain and range of motion, a statistically significant difference was observed between the experimental and control groups (p <0.05).
Conclusion: In general, the results of the present study showed that pain and range of motion in women with chronic low back pain after 12 weeks of training consisting of twelve sessions of treatment during 12 weeks and once a week improves for manual therapy.
