the comparison of the effects of yoga, trx, and combined exercises on pain perception and lordosis angle in women with chronic low back pain and increased lordosis

Background: chronic low back pain (lbp) is one of the most frequent causes of disability in women. aim: the main purpose of the current study was to compare the effects of yoga, trx, and exercise-related combination programs on pain and lordosis in women with increased lordosis and lbp. materials and methods: in this study, 40 women based on the study's criteria were included in the pre-intervention assessments and randomly divided into three experimental groups (yoga, trx, and exercise-related combination programs) and control group. at this stage, the lordosis angle of participants was measured using a flexible ruler, and their pain was also measured via the oswestry disability index. furthermore, the experimental groups performed selected exercises for 60 min/session for three sessions/week for six weeks. results: our results demonstrated that there was a statistically significant difference between the yoga, trx, and exercise-related combination programs in lumbar lordosis (p= 0.003) and pain levels in women with lbp (p= 0.007). also, lumbar lordotic angle showed a significant reduction only in the combined groups subsequent to the period (p= 0.003). conclusion: in conclusion, the current findings illustrated that exercise-related combination program than other modalities could be used as an exercise-related treatment method to ameliorate lordosis angle and pain in women with lbp.
