Details and patient eligibility

About

The aim of this study is to evaluate whether the intensity of pain perceived during the application of extracorporeal shockwave therapy (ESWT) is determinant for producing changes in pressure pain threshold (PPT) in asymptomatic subjects. The investigators will perform a single controlled random trial to three groups. Two of them will receive ESWT whereas the third group will get a cold pressure test (CPT).

Enrollment: 63 patients

Sex: All

Ages: 18 to 40 years old

Volunteers: Accepts Healthy Volunteers

63 participants in 3 patient groups

Shockwave Light Pain Group

Experimental group

Description:

Sham Comparator. It will received a light intensity shockwave in the lateral epicondyle regulated until reach a 3/10 in the Visual Analog Scale (VAS) scale.

Treatment:

Other: Sham Comparator

Shockwave Moderate Pain Group

Experimental group

Description:

Experimental Intervention. It will received a moderate intensity shockwave in the lateral epicondyle regulated until reach a 6/10 in the Visual Analog Scale (VAS) scale.

Treatment:

Other: Experimental Intervention

Cold Pressure Group

Other group

Description:

Control Group. The cold pressure test will be apply to this group. The investigators will use a container with an outer part filled with ice and an inner part filled with water, both separated by a screen that prevents direct contact between the ice and the hand. The water will be regularly stirred to maintain the temperature near to 0.7ºC.

Treatment:

Other: Control Group
