ABSTRACT

BACKGROUND: The prevalence of low back pain is lower when physical fitness (aerobic and muscular) is higher. Strength exercises are important for subjects with low back pain, but there are few studies on the inclusion of aerobic exercise in low back pain programs. The aim of this study was to compare the effects of aquatic exercises with or without high-intensity component on the functional status, lumbar and abdominal muscle endurance, and performance of subjects with chronic low back pain. METHODS: Forty-eight volunteers between 20 and 60 years old were randomly allocated to an experimental group AEDWR (aquatic exercises plus deep-water running group, N.=25) or to a control group AE (aquatic exercises only group, N.=23). The dependent variables included functional status (Repeated Sit-to-Stand test), lumbar (Sorensen test) and abdominal (One Minute Abdominal test) muscle endurance, and physical performance (Maximum Physical Fitness test), which were measured before and after the 9-week intervention and at 21 weeks of follow-up. RESULTS: Lumbar endurance was higher in the AEDWR group at the end of the treatment, with a mean difference (MD) of 43.2 seconds, 95% confidence intervals (CI) (9.6; 76.7), P=0.01, d̅=0.74, and better in the follow-up with MD=40.2 seconds, 95% CI (7.1; 73.3), P=0.02, d̅=0.71, than in the AE group. Participant performance also improved on the 9th week in the AEDWR group, with an MD=0.53 kgf, 95% CI (0.008; 0.98), P=0.02, d̅=0.60. CONCLUSIONS: The addition of deep-water running exercise to aquatic exercises improved lumbar muscle endurance and performance when compared with aquatic exercises only, and this effect was maintained during the follow-up to lumbar muscle endurance.

ABSTRACT

BACKGROUND: Aquatic exercise (AQE) programme is commonly used as an alternative to the chronic low back pain (CLBP) treatment. The addition of aquatic aerobic exercises to AQE may be beneficial to patients with CLBP. DESIGN: Randomised controlled trial. OBJECTIVES: To assess the effectiveness of AQE with the addition of aerobic exercise - deep-water running (DWR) - compared to exclusive AQE in improving disability, lumbar pain intensity, and functional capacity in patients with CLBP. METHODS: Fifty-four adult patients with CLBP were randomised either to the experimental group (AQE + DWR) or the control group (AQE). An assessor who was blinded to the group allocation performed both pre- and post-interventions assessments. Both treatments lasted 9 weeks, with a 3-month follow-up. The primary outcome was disability, as evaluated using the Roland Morris Disability Questionnaire. The secondary outcomes were pain and functional capacity; pain was assessed using a visual analogue scale (VAS), and functional capacity (travelled distance) was measured using the 6-min walk test (6WT). RESULTS: A significant difference in pain was observed between groups after intervention in favour of DWR (mean difference -1.3 cm [95% confidence interval (CI) -2.17 to -0.45], d‾ = 0.80 [95% CI 0.22 to 1.33]). CONCLUSION: Treatment with DWR was effective in the short term for achieving the desired outcome of pain reduction when compared with AQE only but not for disability and functional capacity.
