Background: It has been shown that the decrease of the range of motion in the ankle, due to the presence of latent trigger points in the gastro-sole complex, can affect performance, as well as being a predisposing factor to injury. Objective: To compare the effects of Dry Needling and Foam roller in healthy athletes with limited dorsal ankle flexion by the presence of latent trigger points. Material and methods: This is a clinical trial, single-blind experimental study. The sample will have a total of 44 students, volunteers, healthy of the degree of physiotherapy of the the investigator's university (UCV). Participants who meet the inclusion criteria will be randomly assigned in two groups: Group 1 or Dry Needling (N = 22) and Group 2 or Foam Roller (N = 22). The range of motion of ankle will be assessed through the Leg Motion system (Check Your Motion®, Albacete, Spain). Assessed thought Ankle Test (post-intervention and 24 hours later). The reference values to consider the decreased ankle ROM will be <11.5 cm, <35º measured with Easy Angle® digital goniometer (Meloq AB, Sweden) and/or if it has a difference of 1.5 cm between both extremities. Thus, the effect on previous activity performance will be assessed thought the Counter Movement Jump. Data analysis: Once the distribution of the sample is determined, a descriptive analysis of the data will be carried out and an ANOVA of repeated measures. Will be used to compare the data found in the two groups that make up the study taking into account a 95% CI and an error less than 0.05.
To compare the effects of dry needling and Foam roller in myofascial trigger points. Needling has been shown to decrease pain in the short term; however, its effects on muscle force production are unclear. There are differences between dry needling and foam roller after treatment?
