Brief Summary

Instrument-assisted soft tissue mobilization is a method that uses different devices to approach the myofascial system in variables such as joint mobility and muscle strength. The objective of the study is to assess the effectiveness of the technique of soft tissue mobilization assisted by instruments in increasing the mobility of hip abduction and strength of the hip adductor musculature, in semi-professional rugby players federated in Spain of 18 at 32 years old Randomized, simple blind clinical study. 29 rugby players will be randomized to the two study groups: experimental (assisted soft tissue mobilization in the adductor leg muscles) and control (without intervention). The intervention will last 4 weeks, with 1 session per week, approximately 1 or 2 minutes each. The study variables will be hip abduction mobility (goniometry) and the strength of the hip adductor musculature (sphygmomanometry). A descriptive statistical analysis will be carried out calculating the main statistical characteristics. The distribution of normality will be calculated through an analysis of Saphiro Wilk. With the t-student test of repeated measures the differences will be calculated after the evaluations, and through an ANOVA of repeated measures the intra and intersubject effect will be calculated. The effect size will be calculated using the Cohen mean difference formula It is expected to observe an increase in hip abduction, as well as an increase in the strength of the adductor musculature of the hip.

Outcome Measures

Primary Outcomes (1)

• Change from baseline range of motion of hip abduction after treatment and at month

  A long arm goniometer will be used, following the protocol described by Nussbaumer et al. . Before collecting the data, participants will perform a 5-minute warm-up on an exercise bike. The athlete will be placed supine, attached to the stretcher with a pelvic girth, with the contralateral leg hanging by the edge of the stretcher. The fixed arm of the goniometer will be placed on the transverse line formed by the superior antero iliac spines and the mobile arm on the longitudinal axis of the thigh, matching the goniometer fulcrum with the superior anterior iliac iliac spine of the lower limb to be evaluated. With the help of another physiotherapist, a passive and complete hip abduction will be performed, and the evaluator, in charge of the goniometer, will take the measurement resulting from the test.

  Screening visit, within the first seven days after treatment and after one month follow-up visit

Secondary Outcomes (1)

• Change from baseline strength of the hip adductor muscle after treatment and at month

  Screening visit, within the first seven days after treatment and after one month follow-up visit

Study Arms (2)

Experimental group

EXPERIMENTAL

Each session will last 1 or 2 minutes, with one intervention being carried out a week, over a period of 4 weeks. Prior to the start of training, the instrument-assisted soft tissue mobilization technique will be performed

Other: Assisted soft tissue mobilization

Control group

NO INTERVENTION

Players included in the control group will follow their usual training routine.

Interventions

Assisted soft tissue mobilization OTHER

It will be done for 60 seconds, making a total of 30 strokes with the tool in the longitudinal direction to the muscle fibers. The physiotherapist will previously apply some massage cream to the area to be treated (adductor musculature) so that the tool slides at a 45º angle. Landslides will be made from the femoral condyle to the groin, and vice versa, exerting a pressure with the instrument of 3 over 10 on the analog visual scale that the subject feels
