Not Applicable

Completed

• Conditions: Stretch; Rectus Femoris Muscle; Dry Needling
• Interventions: Other: passive stretching; Other: Deep Dry Needling; Other: Superficial Dry Needling

• Registration Number: NCT04968236
• Lead Sponsor: University of Alcala

Brief Summary

In recent years, dry needling techniques have become widespread in the field of musculoskeletal pain treatment. Specifically, the management of myofascial trigger points has been the focus of these techniques.

One of the objectives has been to improve the flexibility of those muscles that, due to the presence of myofascial trigger points, had a decrease in this parameter.

This study aims to determine whether the application of a dry needling technique is more effective than analytical stretching of the muscle.

Detailed Description

Hypothesis of the study Deep dry needling of latent trigger points of the rectus femoris produces greater effects on flexibility, strength and pain than superficial dry needling or stretching.

- Overall objective: To compare the differences that occur in flexibility, strength and pain threshold to pressure after the application of deep dry needling, superficial dry needling and stretching on latent trigger points of the rectus femoris.

- Specific objectives To determine the changes produced by deep dry needling on flexibility, strength and pain threshold to pressure.

To determine the changes produced by superficial dry needling on flexibility, strength and pain threshold to pressure.

To determine the changes in flexibility, strength and pain threshold to pressure produced by conventional assisted stretching.

To check if the changes remain after 7 days of the application of the techniques.

To assess the inter-rater reliability of the Goniometer APP in the study sample.

Arm && Interventions

Group	Intervention	Description
Passive muscle stretching	passive stretching	With the patient positioned in the supine position, the pelvis stabilized with a strap and the lower extremity where we are going to apply the rectus femoris muscle stretch placed outside the table, we perform a passive stretching technique, increasing hip extension and knee flexion until the patient feels the tension. The position is held for 60 seconds.
Deep dry needling	Deep Dry Needling	With the subject lying supine, we will first locate a latent myofascial trigger point in the rectus femoris muscle.Subsequently, we will apply a deep dry needling technique to the latent trigger point and make 10-12 incisions.
Superficial dry needling	Superficial Dry Needling	With the subject lying supine, we will first locate a latent myofascial trigger point in the rectus femoris muscle.Subsequently, we will apply a superficial dry needling technique to the latent trigger point. Once the needle is placed in the subcutaneous cellular tissue, we manipulate the needle by twisting it until an unpleasant response is provoked. We keep the needle for 5 minutes

Primary Outcome Measures

Name	Time	Method
Muscle strength	Change from baseline at 7 days	Force will be measured by a manual dynamometer (microFET®2, Hoggan Scientific LLC). Measurements will be taken in Newtons (N). It will be evaluated in the movements of flexion of knee. Manual dynamometry has proven to be a tool with excellent intra-examiner reliability to assess isometric force in flexion of the knee, with an intraclass correlation coefficient (ICC) of 0.96 (0.93-0.98).
Knee joint range	Change from baseline at 7 days	Knee flexion motion assessment by using the Goniometer APP, which is a digital goniometer that has proven its reliability and validity.The overall concordance coefficient has shown very good to excellent with active measurements (range, 0.60-0.97).

Secondary Outcome Measures

Name	Time	Method
Pressure Pain Threshold (PPT)	Change from baseline at 7 days	An algometer Wagner FPI 10-WA will be used to determine the PPT in rectus femoris trigger points
