Effects of a Stretching Protocol in Patients With Hip Osteoarthritis

Study Overview
=================
Brief Summary
-----------------
Hip osteoarthritis (OA) is one of the most prevalent chronic disease in the world. Clinical guidelines recommend non-pharmacological conservative treatments for the management of OA. Hip flexors seems to play an important role in the development of hip OA but there is no published studies evaluating the results of a stretching protocol of hip flexors in hip OA patients. The objective of this trial is to evaluate if a stretching protocol of hip flexors is more effective in symptoms, functional capacity , range of motion, strength, muscular length, pain threshold and anxiety and depression compared to control. For this purpose the investigators conduct a single-group, pretest-posttest clinical trial.The investigators included patients diagnosed of hip osteoarthritis Grade I-III by Scale of Kellgren and Lawrence. The variables are measured at the beginning and at the end of treatment of the control phase, and at the end of the stretching protocol phase.
