Abstract.

Objective: To investigate the effects of myofascial release on the flexibility and electromyographic activity of the lumbar erector spinae muscle in healthy individuals. Methods: Ten healthy subjects were recruited to an intervention protocol of myofascial release techniques: (1) superficial myofascial release; (2) deep myofascial release apply along 10 sessions, twice a week, with 40 min per sessions. The outcomes evaluated were flexibility (Toe-Touch Test) and electromyography activity (EMG) of the lumbar erector spinae muscle (Iliocostalis and Longissimus bilaterally) during the movement of extension-flexion of the trunk. Paired t-test was used to compare the electromyographic outcomes, while the Wilcoxon test was used to compare the flexibility outcomes. Results: The myofascial release techniques increased the flexibility (p = 0.005; r = 0.88) and have no influence over the electromyographic activity of the right iliocostalis (p = 0.179; r = 0.43), right longissimus (p = 0.877; r = 0.05), left iliocostalis (p = 0.386; r = 0.29) and left longissimus (p = 0.418; r = 0.27). Conclusions: The application of myofascial release techniques increase flexibility and did not influence over the electromyographic activity of the lumbar erector spinae muscles in healthy individuals. Further studies should include a larger sample with a sham group and/or compare EMG activity of the lumbar erector spinae muscles with patients with low back pain during the movement of extension-flexion of the trunk.
