Table 2 Between Group Differences and Effect Size for Pain, Functional Disability, BME, Lumbar ROM and Quality of Life

From: Effects of non-surgical decompression therapy in addition to routine physical therapy on pain, range of motion, endurance, functional disability and quality of life versus routine physical therapy alone in patients with lumbar radiculopathy; a randomized controlled trial
