Massage and Exercise Increase Body Awareness in Healthy Adults: A Randomized Placebo Controlled Trial

ABSTRACT Objective Physiotherapists are supposed to have a great impact on the body awareness of their clients through passive and active measures. The aim of this study was to investigate the effect of a single session of manual massage or exercise on body awareness. Methods A three-arm randomized controlled study including 96 healthy volunteers (18 - 65 years) was conducted at the Institute of Physical Medicine & Rehabilitation, at the Kepler University Hospital in Linz/Austria. Anonymous questionnaire assessments and analysis with intention-to-treat approach were performed. Participants were assigned to a single intervention of massage (full-body massage with slow strokes and gentle kneading), exercise (moderate body workout, video-based exercise instructions) or lecture on medicinal herbs (video-based lecture, control group). Primary endpoints were the changes of body awareness recorded with the non-verbal Awareness Body Chart test. Secondary endpoints were the changes of body awareness scored with a German body awareness questionnaire (Kurzer Fragebogen zur Eigenwahrnehmung des Koerpers, KEKS) and changes in mood scored with a German questionnaire on mood (Befindlichkeitsfragebogen). Results The Awareness Body Chart total score increased in both intervention groups but not in the control group with significant differences in the change between control group and both other groups (massage vs. control: +0.47, 95% CI 0.30 to 0.64; exercise vs. control: +0.31, 95% CI 0.15 to 0.45; massage vs. exercise: +0.19, 95% CI -0.02 to 0.34). An increase of the KEKS total score was found in the exercise in comparison to the control group. Mood significantly improved in both intervention groups compared to the control group. Conclusions In this study single session interventions of massage or exercise presented immediate positive impact on body awareness and furthermore on mood. The trial may serve as a prototype for further research on body awareness. Trial Registration Registered in the clinicaltrials.gov database ( NCT05004272 )
