Background and Aim: Myofascial Release (MFR) is a soft tissue mobilisation technique that has been widely researched and supported to increase muscular flexibility and joint range of motion along Superficial Back Line (SBL) structures. The purpose of the present study is to examine and compare the acute effects of MFR and post-isometric relaxation (PIR) applied on plantar fascia, on flexibility of superficial back line (hamstring muscle).
Design: This was a pilot single blind Randomized Control Trial (RCT).
Participants: Thirty young healthy students (24 boys and 6 girls; mean age 21.46 ± 0.97)
Methods: Inclusion and exclusion criteria were followed, and baseline measurements for the Toe-Touch Test (TTT) and active Straight Leg Raise Test (SLRT) were obtained. Subjects were then ran-domly assigned to the MFR group and the PIR group. The MFR group received the technique on plantar surface of the feet by applying a gentle and sustained pressure into the myofascial connective tissue. The PIR group received the technique on plantar flexors by placing them in stretched position, performing isometric contraction followed by relaxation and lengthening. Both interventions will be performed for 10 minutes. Afterwards, the Toe Touch Test and straight leg raise test were re-assessed.
Results: Before and after intervention SLRT (both right and left) and TTT difference (within group differences) is statistically significant (p<0.05) in both MFR and PIR group. Between-group com-parison also shows significant difference in both groups with p<0.05. The MFR group showed a significant difference in the SLR test and Toe Touch test compared to the PIR group (p<0.05).
Conclusion: The results of the current study showed that MFR on the planter fascia was immediate-ly effective for improving flexibility of the SBL for the hamstring muscle.
