Regarding functional capacity, we understand that the procedure fitted the expected results, since it could improve activities of daily living, i.e., it included joint mobility exercises, connective tissue stretching, aerobic exercise and strength-resistance exercises. All of these techniques have been sufficient to achieve our purpose, because we must not forget their overall effects at intra-articular level, anti-inflammatory effect, temperature rise and improved cellular oxygenation, analgesic effect, venous return improvement and muscle flexibility, etc.<a class="elsevierStyleCrossRefs" href="#bib0250"><span class="elsevierStyleSup">22,23</span></a></p><p id="par0070" class="elsevierStylePara elsevierViewall">Regarding the severity of the disease we found statistically significant differences.

First, it would have been convenient to have a larger sample, as only 30 of the initial 90 people participated in the end. Nevertheless we can confirm that the number of participants was sufficient to allow parametric tests. Second, it would be interesting, in future research, to use a placebo group. However, taking into account the characteristics of the procedure, in this case it would be difficult. The sample could also be extended to people with other chronic diseases, such as fibromyalgia, osteoarthritis, or sclerosis, in order to verify the effect of this exercise program in patients with these characteristics. Certainly a different procedure of aquatic exercise might be considered to see if better results would be obtained compared to the present study.
