A randomized trial of the effects of an aquatic exercise program on depression, anxiety levels, and functional capacity of people who suffered an ischemic stroke.

BACKGROUND: Aquatic exercise programs are used in rehabilitation and might help to reduce disability after stroke. This was a randomized intervention trial to assess the influence of an aquatic exercise program on people suffering from depression and anxiety after ischemic stroke. METHODS: Participants were randomized to an experimental group (EG) composed of 19 individuals (51.8 +/- 8.5 years; ten males and nine females), and a control group (CG) composed of 17 people (52.7 +/- 6.7 years; nine males and eight females). The aquatic exercise program consisted of two sessions per week, each lasting between 45 and 60 minutes and divided into 5 to 10 minutes exercise sections during 12 weeks. The State-Trait Anxiety Inventory was used to determine anxiety levels while the Beck Depression Inventory was used as a self-assessment of depression. RESULTS: EG improved measures of depression, anxiety trait and anxiety state between pre- and post-treatment, with no changes in CG. EG improved in all tests related to functional capacity compared to CG. CONCLUSIONS: The practice of aquatic exercises promotes improvements in the levels of depression and anxiety in people who suffered an ischemic stroke.
