Effectiveness of radial nerve mobilization techniques and their interfaces for treating chronic epicondylalgia Intervention: This is a randomized controlled clinical trial that will evaluate the effectiveness of adding radial nerve and its interface mobilization techniques to conventional musculoskeletal treatment. Participants: Patients over 18 years of age with a diagnosis of chronic epicondylalgia and a positive radial nerve neurodynamic test. Those with previous infiltrations, concomitant pathologies, or contraindications will be excluded. Study Groups: * Control Group (n=23): Will receive conventional musculoskeletal treatment. * Intervention Group (n=23): Will receive the same conventional treatment plus mobilization of the radial nerve and its interfaces. Primary Outcomes: * Pain (NPRS). * Pain and functionality (PRTEE). * Pressure pain threshold (Algometry). * Pain-free grip strength (Dynamometry). * Central sensitization (CSI). Assessments will be conducted at baseline, one week after the last treatment, and 3 months after the last treatment.

A general massage of the forearm will be performed. The physical therapist perform deep, longitudinal strokes. Pressure will be maintained at a level the patient finds comfortable for 3 minutes.
Pressure will be applied to trigger points in the forearm. This will be done in three sets of 30-second applications, with 30 seconds of rest between each.
A lateromedial glide will be performed. The technique will be applied for three sets of 10 repetitions, with 30 seconds of rest between each set.
Three sets of 30 nerve glides will be performed at a rhythm of one second of tension followed by one second of rest. There will be 30 seconds of rest between sets.
A real technique of Diacutaneous fibrolysis will be applied to the forearm region for 5 minutes.
A sham Diacutaneous Fibrolysis technique (skin pinch) will be applied to the forearm region for 5 minutes.
Pain Intensity
Numeric Pain Rating Scale. Score from 0 to 10. Zero is equivalent to no pain and 10 indicates the worst possible pain.
Time frame: From enrollment to the end of treatment (4 weeks), and to the end of the study at 16 weeks.
Pain and Functional Disability
Patient-Rated Tennis Elbow Evaluation. Score from 0 to 100. Higher score indicates more pain and functional disability and zero indicates no pain and disability.
Time frame: From enrollment to the end of treatment (4 weeks), and to the end of the study at 16 weeks.
Handgrip
Grip strength is assessed in kilograms. The value used is the average of three repetitions.
Time frame: From enrollment to the end of treatment (4 weeks), and to the end of the study at 16 weeks.
Pressure pain threshold - Elbow
Pressure pain threshold at the elbow. The lowest intensity of pressure that the subject perceives as pain when applied to the lateral epicondyle is recorded. The value used will be in kilograms per square centimeter.
Time frame: From enrollment to the end of treatment (4 weeks), and to the end of the study at 16 weeks.
Pressure pain threshold - short radial extensor
Pressure pain threshold at the Short radial extensor.The lowest intensity of pressure that the subject perceives as pain when applied to the short radial extensor is used. The value used will be in kilograms per square centimeter.
Time frame: From enrollment to the end of treatment (4 weeks), and to the end of the study at 16 weeks.
Pressure pain threshold - Radial nerve
Pressure pain threshold at the radial nerve. It is used to record the lowest intensity of pressure that the subject perceives as pain when applied to the radial nerve tunnel. The value used will be in kilograms per square centimeter.
Time frame: From enrollment to the end of treatment (4 weeks), and to the end of the study at 16 weeks.
Central sensitization syndrome
Central Sensitization Inventory. The questionnaire is scored on a scale from 0 to 100. A score above 40 is considered to indicate central sensitization.
Time frame: From enrollment to the end of treatment (4 weeks), and to the end of the study at 16 weeks.
Subjective perception of clinical evolution
Global Rating of Change scale. The scale consists of 15 points, ranging from -7 ("Much worse") to +7 ("Much better"). For clinical interpretation, values below "Somewhat better" or "Somewhat worse" are considered clinically unchanged. Values greater than or equal to "Somewhat better" are considered clinically improved, and values greater than "Somewhat worse" are considered clinically worsened.
Time frame: From the 4 week to the end of study at 16 weeks
