Effects of MatPilates in Pain and Functionality in Elderly Woman With Osteoarthritis.

Introduction: The osteoarthrosis is incurable, one of the most incapacitating disease around the world and your prevalence is increasing every year. The main consequences of this disease is pain and loss of functionality as a result of biomechanical limitations coming from articular inflammation. Among the variability of therapeutic resources, we propose MatPilates like a no drug intervention, that probably will contribute for a decrease in the symptoms of this disease. Objective: It is hypothesized that MatPilates is a method capable of decrease pain and increase functionality in elderly woman with osteoarthrosis. Methods: This study is a randomized double blind clinical trial, in which the volunteer need be in between 60 and 69 years old. Will be formed of two groups: MatPilates Group (MG) and Control Group (CG), and the ideal "n" will be calculated in a pilot study.

The one who assess the patients in the beginning and in the final moment (investigator) not know in what group the patient is. As the investigator that will do the statistic (outcome assessor).

In the beginning was nominated Contrology, but today is known as Pilates. Created by Joseph Humbertus Pilates. This technique is based on respiration, balance, flexibility, proprioception and muscular strength. One of the main work is on the power house (core), biomechanical axis of the body, composed of muscles: rectus abdominis, paravertebral, multifidus, diaphragm, and those of the perineal center.

The MatPilates program was specialized developed for this trial, in which all exercises belong to contemporaneous Pilates style. Each session has 60 minutes of duration, divided in three blocs (stretching, exercise and relaxation), with mean of 10, 40 and 10 minutes respectively (VIEIRA et al., 2016). Each exercise will be performed in one series of 10 to 15 repetitions and will be modified accordingly the patient need.

Will not be submitted to any physical intervention. It continues in your daily life with only phone monitoring.
