Effectiveness of strengthening exercise plus activities of daily living instructions in reducing pain in patients with lumbar disc herniation
Lumbar disc herniation (LDH) is one of the most common causes of mechanical low back pain (LBP) associated with radiating leg pain. Conservative treatment, including exercise, analgesic, and physical therapy, is regarded as the first-line treatment of LDH. This randomized clinical trial was conducted to evaluate the effectiveness of back and hip strengthening exercises combined with activities of daily living instructions (ADLIs) to reduce pain intensity in patients with LDH. A total of 70 patients with LDH were randomly allocated to either the intervention group (IG) or the control group (CG). Patients in IG received different back and hip strengthening exercises five days a week for six weeks. The patients in CG were treated with Naproxen (500 mg) and Baclofen (10 mg) tablet twice a day for three weeks, followed by hot moist compression for the next three weeks. In addition, the patients in both groups were instructed to follow the ADLIs during the intervention and at least 3 months after the intervention. The straight leg raising (SLR) test and the Visual Analogue Scale (VAS) score were used to evaluate the patients' pain intensity. Outcomes were measured at baseline, at three weeks, and at six weeks of the intervention. Patients were followed up after 3 months of the intervention.
