The purpose of this study is to determine whether dexketoprofen administered by phonophoresis or iontophoresis is more effective in the treatment of subacromial syndrome that the conventional therapy with ultrasounds.

It is a question of valuing the decrease of the pain (by means of the visual analogic scale pain score) and the increase of the functionality of the joint (by means of Dash and Constant scores) of three different treatments from physical therapy to establish the most effective protocol for the treatment of the subacromial syndrome.

Determine the best physiotherapy treatment for subacromial syndrome with 20 sessions of different treatments.
