<![CDATA[Background: Low back pain (LBP) is pain or discomfort occurring in the area below the costal margin and above the gluteal fold. Previous studies showed that vitamin D supplementation can alleviate complaints of chronic LBP. Aim: This study investigated the effect of vitamin D supplementation on pain and quality of life in elderly patients with chronic LBP. Material and methods: This study uses the experimental method of randomized controlled trial pre- and posttest design on 16 geriatric patients who were divided into two research groups (intervention and control group). The intervention group had usual rehabilitation therapy and vitamin D3 supplementation at a dose of 5000 IU, whereas the control group only had usual rehabilitation therapy. Pain was measured by the Numerical Rating Scale (NRS), level of vitamin D, and quality of life was assessed by the Short Form (SF-36) before and after 4 weeks. Result: Both groups, rehabilitation only and rehabilitation combined with vitamin D3, had significant pain reduction after 4 weeks of treatment (p < 0.002 and 0.006 consecutively), but no significant difference between groups (p = 0.893). Conversely, there was statistically significant improvement in the level of vitamin D ( p = 0.026 (p < 0.05)) and SF-36 component vitality ( p = 0.014 (p < 0.05)), mental health ( p = 0.014 (p < 0.05)), social function ( p = 0.006 (p < 0.05)), and pain in the body ( p = 0.002 (p < 0.05)). Conclusions: The administration of vitamin D supplements in patients with chronic LBP has the potential to alleviate symptoms and provide significant benefits in enhancing the patient's quality of life.]]>
