Summary

The interest in studying the impact of aquatic exercise on muscle strength of patients with rheumatoid arthritis came after publication of several studies that pointed to the potential benefit of exercise on the natural history of the disease, including reduction of pain, better immune response as well as aerobic fitness and functional capacity and increase muscle strength, endurance and quality of life.

In general, the aquatic exercises are indicated for patients with chronic joint diseases, since the aquatic environment seems to be more secure for this population due to the reduction of joint loading, as well as gain range of motion.

However, there are some difficulties to show the real and consistent beneficial effect of physical activity in these patients, such as the small number of randomized controlled clinical trials, short intervention period (4-8 weeks), lack of details of the exercise protocols used, methodological problems (heterogeneous measures to evaluate the outcome, change of medication). Moreover, no study evaluated the disease activity, according to the tool most used clinically worldwide, the DAS28.

It is known that aquatic exercises without impact in healthy subjects are sufficient to gain muscle strength. Nonetheless, in people with joint limitation the benefits from these same exercises to gain muscle strength is not known.

To date, no studies addressing the effect of aquatic exercise on muscle strength and disease activity in patients with rheumatoid arthritis. In addition, there is the need to obtain a standardized protocol for prescribing of aquatic exercises. The choice of lower-limb strength was based on its relevance to the acceleration and deceleration during the march, as well as to perform activities of daily living, leisure and professional in these individuals.

Thus, this study aims at:

1. Exercises performed in the aquatic environment and without the concomitant use of overhead equipment are sufficient to promote gain muscle strength in the lower limb?
2. What is the isolated effect of water resistance on muscle strength? Could it work as an impact that is used in exercises done on the land?
