The objective of this study is to assess if the masotherapy with neural tension is more effective than non-neural tension to improve and reduce tremor in patients with Parkinson's disease. The project will be carried out in clinics, where both data collection, assessments and scales will be carried out, as well as the plan and intervention in which the neural tension massage therapy of the radial nerve will be applied to the first intervention group; and massage therapy without neural tension in the second group.

In this study the investigators are going to compare the effectiveness of two treatments (masotherapy with neural tension and masotherapy with non-neural tension) in patients with Parkinson disease based on the improved of pain, tremor, functional and life quality.

The investigators are going to divide the number of volunteers in two groups. The first group is going to be treated during 8 weeks with conventional (non-neural tension) masotherapy in the upper limb, the other group is going to be treated with radial neural tension masotherapy during 8 weeks also. To apply the neural tension, the investigators position the patient's upper limb lowering the scapula, elbow extended, internal rotation glenohumeral, forearm pronation, bend and cubital deviation of the wrist, fingers bended and thumb adduction, and finally glenohumeral abduction.

To compare the results between the different groups, the investigators are going to value the patients 4 times, the first one before the beginning of the treatment, the second one and the end of the treatment, the third one after one month completing the treatment, and the last one after three months completing the treatment.
