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).

• Asymptomatic Condition

Interventions

Type	Name	Description
OTHER	Sham Comparator	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).
OTHER	Experimental Intervention	The investigators will apply a moderate 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 6/10 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 (6/10 in VAS).
OTHER	Control Group	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.
