WATSU (Water-Shiatsu) increases body awareness and improves pain and mood: A randomised controlled study

Abstract

Background and purpose

WATSU (Water-Shiatsu) is a body-oriented therapy in warm-water pool with passive movements, massage and breathing techniques. The present study investigated the short-term effect of a single session of WATSU on body awareness.

Materials and methods

In a randomized-controlled study 60 volunteers (18–65 years) were assigned to a 20-min intervention of WATSU or to a 20-min lecture on WATSU. Immediately before and after the intervention they had to answer questionnaires. Primary endpoint of the investigation was the change of the total score of the non-verbal Awareness Body Chart (ABC). Secondary endpoints were the changes of the scores of the 14 single body parts of the ABC, of the Visual Analogue Pain Scale, of a German self-perception questionnaire (KEKS) and changes in mood scored with a German questionnaire on mood (Bf-SR). To compare groups, Mann-Whitney U tests were used.

Results

The WATSU group had a significantly higher increase in the ABC total score in comparison to the lecture group (WATSU: 0.3 (IQR 0 – 0.8), lecture: 0.1 (IQR -0.2 – 0.2), p = 0.014). In the KEKS no group differences were seen. In WATSU a significantly stronger improvement of pain (Visual Analogue Pain Scale: WATSU: −15 (IQR -29 to −8), lecture: −4 (IQR -9 – 2), p < 0.001) and of mood (Bf-SR: WATSU: −6 (IQR -14 to −2), lecture: −1 (IQR -5 – 1), p = 0.003) could be observed.

Conclusion

This study showed that WATSU immediately increases body awareness and improves pain and mood.
