About

Limited ankle functionality is one of the main causes of runner injuries. The use of flossing techniques are used to improve functionality. The administration of an expectation can modulate corticospinal excitability, improving the therapeutic response.

The objective of the study is to evaluate the effect of inducing a positive expectation along with the application of flossing on the ankle functionality in healthy amateur runners.

Randomized clinical study, single blind, with follow-up period. 20 runners will be randomized to the two study groups: experimental (flossing technique with a positive expectation) and control (flossing technique with a neutral expectation). The study variables will be: dorsal ankle flexion (Weigh Bearing Lunge Test), isometric force in plantar ankle flexion (dynamometry), elastic-explosive force (Countermovement Jump) and stability (Y Balance Test). Using a Shapiro-Wilks analysis, the sample distribution will be calculated. The changes after each evaluation will be analyzed with the t-student test of related samples and through an ANOVA of repeated measures the intra and intersubject effect will be observed. The effect size will be calculated using Cohen's formula.

It is expected to obtain changes in the variables between both groups and in the group / time interaction, which suggest an effect of the expectation on corticospinal excitability in healthy athletes.

0 participants in 2 patient groups

Experimental group

Experimental group

Description:

Each session will last 10 minutes and a weekly intervention will take place over 3 weeks. The intervention by flossing will be carried out following the application protocol described by the manufacturer for the application of flossing on the ankle. Before the intervention, participants will perform a standard warm-up: 10 minutes of exercise bike at a moderate intensity

Treatment:

Other: Positive expectation

Control group

Active Comparator group

Description:

Each session will last 10 minutes and a weekly intervention will take place over 3 weeks. The intervention by flossing will be carried out following the application protocol described by the manufacturer for the application of flossing on the ankle. Before the intervention, participants will perform a standard warm-up: 10 minutes of exercise bike at a moderate intensity

Treatment:

Other: Neutral expectation
