Background: Evidence-based clinical guidelines consider physical exercise one of the best nonpharmacological interventions for low-back pain (LBP), but it is necessary to clarify the exercise-induced hypoalgesia effect of different modalities of exercise in chronic pain populations. Purpose: This study focused on exploring acute changes in tactile and pressure-pain perception and lumbar strength and flexibility in patients with nonspecific chronic LBP (NSCLBP) after performing one of three 20-minute physical exercise modalities. Methods: A total of 81 patients with NSCLBP were pseudorandomly distributed into three groups of 20-minute physical exercise--1) aerobic (n=21, mean age 42[+ or -]9.72 years, nine men), 2) stretching (n=21, mean age 40[+ or -]11.37 years, ten men), and 3) strengthening (n=20, mean age 35.80[+ or -]11.56 years, ten men)--and 4) a control group (n=19, mean age 38.64 [+ or -]10.24 years, eight men), and completed self-reported questionnaires during the same period. Tactile and pressure-pain thresholds and isometric lumbar muscle endurance and flexibility were assessed before and after this brief exercise-based intervention. Results: All groups were comparable in terms of sociodemographic and clinical data, cardiovascular capacity, and self-reported data onphysical disability, mood, motivation, psychological response to stimulus properties of physical exercise, and physical activity enjoyment. Our analyses revealed higher tactile sensitivity (p Conclusion: These results add some evidence about different modalities of exerciseinduced hypoalgesia in NSCLBP. However, the fact that we also found improvements in the control group limits our conclusions. Keywords: low-back pain, exercise therapy, aerobic exercise, flexibility
Introduction With a vital prevalence of 70%-80%, low-back pain (LBP) is one of the ailments most experienced by the general population and the main cause of disability in industrialized countries, [...]
