OBJECTIVE:To analyze the effect of the 'Exercise Without Movement' (E.W.M) yoga method on mindfulness and on the improvement of anxiety and depression symptoms. METHODS: A quasi-experimental study examined the effect of one month E.W.M. intervention among 38 participants who were enrolled voluntarily to both groups, study (n = 16) and control (n = 22). Five participants dropped out during the study. The State Mindfulness Scale (SMS) was used to measure mindfulness. The Anxiety Inventory Beck (BAI) and the Beck Depression Inventory (BDI-II) were used to measure the anxiety and depression symptoms, respectively, before and after the intervention. RESULTS: Study group showed both a statistically significant increase in mindfulness and decrease in anxiety and depression symptoms, compared with the control group. CONCLUSIONS: The E.W.M. has been useful in the development of mindfulness and in the treatment of anxiety and depression symptoms and may represent a new method in the mindfulness-based therapeutic application.
