Effect of Therapeutic Techniques on Leg Stretching in Healthy Subjects

A randomized clinical trial blind crossover. The aim of this study is comparing the immediate effect of five interventions on the flexibility of hamstrings in healthy individuals. Participants will be assessed pre and post intervention through the extended leg elevation test and photogrammetry. The techniques of unilateral lumbar mobilization, proprioceptive neuromuscular facilitation, massage, ventosa therapy and foam roller will be applied on different days with a 48‐hour interval between interventions. The techniques will be compared using the repeated measures ANOVA after verification of normality by the Shapiro‐Wilk test, adopting the significance level of 5% and 95% confidence interval.
