The effect of hydrotherapy on pain intensity and functional ability in lumbar disk herniation (LDH) patients that
undergo non-operative procedure; pre-experimental study at medical rehabilitation installation of RSUP
dr. Mohammad Hoesin Palembang. Lumbar disk herniation (LDH) is the most common disease that becaused low back
pain and functional disability. Some studies mentioned that hydrotherapy is an effective treatment for low back pain.
Therefore, this study was conducted to determine the effect of hydrotherapy on reducing pain intensity and improving
functional ability in LDH patients. This study was a pre-experimental study with one group pretest-posttest design. Data
was collected by direct interviews to the patients using visual analogue scale (VAS) to measure pain intensity and
Modified Oswestry Low Back Pain Disability Questionnaire to assess functional ability before and after underwent
hydrotherapy once a week for 4 weeks. The data then undergo Shapiro-Wilk normality test and continue with Paired t-Test or Wilcoxon test. From 30 subjects, it was found that there are effects of hydrotherapy on reducing pain intensity
(p<0,001) and improving functional ability (p<0,001) in LDH patients that undergo non-operative procedure at the
Medical Rehabilitation Installation of RSUP Dr. Mohammad Hoesin Palembang. There are effects of hydrotherapy on
pain intensity and functional ability in LDH patients that undergo non-operative procedure.
