The effect of aquatic physical therapy on patients with multiple sclerosis: A systematic review and meta-analysis

The aquatic environment has unique properties, such a buoyancy, turbulence, hydrostatic pressure, and resistance, which can be used to gain a range of exercise benefits. During the last decade, hydrotherapy has spread in a very heterogeneous rehabilitation field. However, the efficacy of this kind of rehabilitation is not clear in scientific literature. The purpose of this study is to conduct a systematic review with meta-analysis to evaluate the qualitative and quantitative results of physical therapy treatments in an aquatic setting for individuals with Multiple Sclerosis.

PRISMA guidelines were used to carry out the systematic review and meta-analysis. Three bibliographic databases were searched: MEDLINE, PEDro, and the Cochrane Library. Papers included in the study have the following characteristics: (a) a randomized controlled trial design of research and (b) published in English. The quality of the clinical trials included were evaluated according to a Jadad score and through meta-analysis.

After the elimination of duplicates, 116 records were screened. Among these, 11 Randomized Controlled Trials (RCTs) were included in the systematic review. Ten of these were involved in the meta-analysis. From the qualitative analysis, a larger number of studies were found with a high level of quality. Most of the results of the quantitative analysis were statistically significant (p< 0.05).

Aquatic physical therapy is a valid means of rehabilitation for people with Multiple Sclerosis. The integration of this methodological approach with conventional physical therapy is recommended. Nevertheless, more studies, a larger number of participants, and short-, medium-, and long-term follow-up are required to confirm current results.
