Effect of Balneotherapy on Chronic Low Back Pain at Hot Springs in Southern Ethiopia: Perceived Improvements from Pain

BACKGROUND: Low back pain (LBP) is an important musculoskeletal condition results in clinical, social and public health problems globally. Hydrotherapy, using water and heat together can be utilized to treat conditions, relieve pain and increase muscular power and a range of joint movement in patients with chronic lower back pain. Most patients with acute LBP improve spontaneously within four weeks; however, chronic LBP is extremely common and usually mechanical in nature. OBJECTIVE: The objective of the current study was to assess effect of balneotherapy in decreasing the lower back pain and its improvements among adults using a spa in southern Ethiopia. METHODS: We employed a single arm cohort study and convenient sampling method to select 442 study participants from four hot springs located in Sidama Region and Gedeo Zone, Southern Ethiopia. Structured and pretested questionnaire was used and administered face-to-face by trained data collectors. Data were entered using EpiData and transferred to SPSS for cleaning and analysis. Descriptive and bivariate analyses were made. RESULTS: A total of 427 participants were included in the study giving response rate of 96.6%. The mean (standard deviation) age of respondents was 42.55 (±14.92) years. Perceived improvement from back pain was 332 (77.8%) with 95% confidence interval (CI) of 74–82%. Factors showing association with perceived improvement from back pain after spa therapy were, study site being near Hawassa (Burkitu) with crude odds ratio (COR) of 3.3 and 95%CI: 1.83–5.98 and p-value <0.001; and sex of respondents that the odds of perceived improvements among males were about twofold compared with females, (COR: 1.7, 95%CI: 1.07–2.74, p-value 0.025. CONCLUSION: Our study shows significant perceived improvement from back pain after utilization of spa water. This is associated with type of hot spring used, male sex, and having neurological symptoms. Therefore, hot spring spa water had better therapeutic effect for back pain and emphasis should be given to integrate it with modern medicine and further experimental study to be conducted to recommend it for medical purposes.
