Effects of Home Exercise and Manual Therapy or Supervised Exercise on Nonspecific Chronic Low Back Pain and Disability

In this study, we aimed to evaluate the effects of two therapeutic methods: home-based exercise and manual therapy (MT) or supervised exercise on pain and functional status in individuals with chronic nonspecific low back pain. In total, 60 individuals with LBP were included in this randomized study. All participants were treated for 6 weeks in one of two groups: the manual therapy group or the exercise therapy group. In addition, all participants were asked to perform an exercise program at home independently. Levels of pain, spinal mobility, disability, and abdominal and back muscle endurance were measured before and after 6 weeks of intervention. Results: After MT, disability was reduced by 70% (F = 42.2; p < 0.00; eta(2)(p) = 0.99) and pain was reduced by 78% (F = 4.9; p < 0.00; eta(2)(p) = 0.51). After exercise therapy, disability and pain were reduced by 78% (F = 11.5; p < 0.00; eta(2)(p) = 0.78) and 68% (F = 9.4; p < 0.00; eta(2)(p) = 0.41), respectively. Muscle endurance and lumbar spine mobility values were significantly higher in both groups after 6 weeks of intervention (p < 0.00). After 12 MT interventions, lumbar spine mobility increased by 40% (F = 1.9; p < 0.00; eta(2)(p) = 0.24) and after exercise therapy by 38% (F = 28.4; p < 0.00; eta(2)(p) = 0.82). Abdominal muscle endurance improved by 29% (F = 24.2; p < 0.00; eta(2)(p) = 0.79) after MT and by 34% (F = 57.6; p < 0.00; eta(2)(p) = 0.67) after exercise therapy; back muscle endurance improved by 18% (F = 48.6; p < 0.00; eta(2)(p) = 0.78) after MT and by 20% (F = 14.2; p < 0.00; eta(2)(p) = 0.76) after exercise therapy. After 6 weeks of intervention, there was no statistically significant difference between the pain, disability, and spinal mobility groups (p > 0.05). However, differences between groups in kinesiophobia (p = 0.02), back (p < 0.02) and abdominal (p < 0.03) muscle endurance values were statistically significant. Following the home exercise program and manual therapy, or the home exercise program and supervised exercise, LBP and disability had clinically significant reductions and functional status showed improvement.
