Abstract

BACGROUND: Low back pain (LBP) has been regarded as one of the musculoskeletal problems which is affecting more than three-quarters of individuals in their lifetime. Nowadays, various pharmacological and nonpharmacological therapies are employed for relieving and treating LBP. This study was conducted to compare the effects of topical hot salt and hot sand on patients' perception of LBP. MATERIALS AND METHODS: In this, quasi-experimental study patients with LBP referring to the orthopedic clinic of Shahrekord educational hospital were divided randomly into two interventions and one control group in 2020. All three groups were received naproxen cream and daily physiotherapy in the same manner, the interventional groups in addition either topical hot salt or topical hot sand. Data gathering tool for measuring patients' perception of LBP was the McGill Pain Short Form Questionnaire to be completed at the beginning, immediately at the end, and 2 months after the intervention. The data were analyzed using SPSS statistical software (version 21.0). RESULTS: Totally, 90 patients were randomized based on the table of random numbers (mean age 51.1 + 11.1), and finally, 87 patients completed the study. Patients' perception of LBP before the intervention was homogenous in hot salt, hot sand, and the control group The mean score of total pain experience before the intervention was 14.1 ± 11.3 for hot sand, 13.9 ± 10.7 for hot salt and 13.7 ± 10.1 for control group The mean scores of these three groups were not significant before the intervention (P > 0.05). The mean score of total pain experience immediately after the intervention was 6.7 ± 4.2 for hot sand, 5.2 ± 3.1 for hot salt and 13.9 ± 9.8 for control group. The mean scores of the hot sand group and the hot salt group were significantly decreased compared with control group (P > 0.05). The mean score of total pain experience two months after the intervention was 5.6 ± 3.27 for hot sand, 4.21 ± 2.14 for hot salt and 13.8 ± 10.4 for control group. Mean score of total pain experience in both intervention groups had significantly reduced two months after the intervention compared to control group (P ≤ 0.001); so that the effect of hot salt treatment on reducing total pain experience was larger than hot sand (P ≤ 0.001). The same trend was observed for VAS and Present pain intensity variables. CONCLUSIONS: The findings have revealed that the topical treatments with hot salt and hot sand could have a significant effect on the perception of LBP compared to those in the control group; whereas hot salt might be stronger effects than hot sand on reducing LBP.
