The Effect of 8 Weeks of Selected TRX Exercises on Pain Intensity and Static and Dynamic Balance of Non-Athlete Girls with Non-specific Chronic Back Pain

The present study examines eight weeks of TRX training on the pain and suffering of non-athlete girls with chronic non-specific low back pain.

The statistical population of the study includes non-athlete girls with non-specific low back pain in the two cities of Shiraz with pain of more than three months. Among them, 30 participants were selected in two groups, experimental (15 people, age: 26.3± 1.84 years, height: 160.11± 5.43 cm, weight: 68.27± 7.34 kg) and control (15 people, age: 26.74 ± 3.01 years, height: 160.4 ± 02/87 cm, weight: 66.1±7.247 kg). To measure the amount of pain, the analogical visual analog scale of pain (VAS) and static and dynamic balance were used by Biodex switching device. First the pre-test was performed and then the experimental group performed the training protocol for 8 weeks and the control group did not perform the exercise and then retested. The research variables were analyzed in two sections of descriptive and inferential statistics in using SPSS software version 20. Shapiro-Wilk test was used for data normality and paired t-test was used for in-group comparison and ANCOVA test was used as a covariance to compare the data obtained from the research groups. Significance level was considered throughout the study at the level of 95% with alpha less than or equal to 0.05.

The results showed that the difference between the pre-test and post-test scores on pain intensity, static and dynamic balance of TRX exercise group was significant (p<0.05), that is, the scores on the post-test were higher than those on the pre-test. However, the difference was not significant (p<0.05) regarding the control group.

According to the results of the present study, the TRX training protocol used in this study improved pain and static and dynamic balance of non-athlete girls with non-specific chronic low back pain.
