Acute effects of myofascial release technique on flexibility and pain: outcome for chronic low back pain

Background: Myofascial release technique (MFR) is frequently used in the treatment of patients with chronic low back pain (CLBP), but there are limited studies on the acute effects of this technique. It was aimed to determine the acute effect of MFR technique on pain and flexibility in CLBP. Methods: Forty CLBP patients (19 female; 21 male) with an average age of 40 years were randomized as MFR technique and classical massage groups. A single session of technique was applied to each group. Outcome measurements consisted of the Visual Analogue Scale (VAS), Sit and Reach Test (SRT), Straight Leg Raise Test (SLRT), and Modified Schober Test. Results: In within-group comparisons, all outcome measures (except right-SLRT) improved statistically significantly in both groups after interventions (p˂0.05). ANCOVA was conducted to determine whether there were significant differences in between groups after intervention while controlling for age. The analysis showed that VAS, SRT and left-SLRT results were significantly more improved after the MFR technique compared with classical massage (p˂0.05). Conclusion: In conclusion, the MFR technique is a safe and effective method for the immediate relief of pain and the enhancement of flexibility. Furthermore, it demonstrates superior efficacy in pain relief and flexibility improvement compared to classical massage, which is another manual therapy technique.
