Brief Summary
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).

Primary Outcomes (1)
Pressure pain threshold
The investigators will use a digital algometer (Force Ten FDX Wagner) to measure when pressure becomes pain.

Study Arms (3)
Shockwave Light Pain Group
EXPERIMENTALSham 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.
Shockwave Moderate Pain Group
EXPERIMENTALExperimental 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.
Cold Pressure Group
OTHERControl 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.
Interventions
The investigators will apply a light intensity shockwave in the lateral epicondyle with the portable SHOCKMASTER 300 at a 8Hz frequency and 2000 impulses. The intensity will be regulated to reach a 3/10 in the VAS scale, depending on the tolerance of the subject. Each patient will receive between 5 and 10 impulses starting with the lower intensity of the device (middle energy: 1 bar) and will go up towards the target (3/10 in VAS).

Patients will place their hand, wide open and up to the wrist, into the inner part of the container and will keep it under water for a maximum time of 2 minutes. If pain is unbearable before the time ends, the participant will be able to withdraw the hand.
