The shoulder is a mobile structure which generates a lot of pathologies. One of them is rotator cuff tendinosis. On the other hand, it has been investigated that Maitland is effective for reducing pain and for mobility in the cervical and lumbar spine and in joints such as the knee and ankle, however, there are few studies that confirm that it is effective in shoulder pathologies.So here the investigatprs want to study the effectiveness of Maitland as an adjunctive treatment for shoulder pathologies, comparing it with conventional physiotherapy treatment, in relation to the reduction of pain and increased mobility. For that the investigators have a randomized clinical trial with two group.

Group 1 receives tens, SW, conventional physiotherapy and exercises as treatment. Group 2 receives tens, SW, Mailtland, and exercises. An assessment is carried out at the beginning of the treatment, at the end and 2-4 weeks after finishing the treatment. The EVA ASES, DASH and SF-36 scales are included and the biomechanics study is used for the range of mobility.
