- Registration Number
- NCT03519698
- Lead Sponsor
- ARCIM Institute Academic Research in Complementary and Integrative Medicine
- Brief Summary
A randomized, controlled, three-arm study to investigate the effects of footbaths with ginger, mustard or warm water alone in female, adolescent patients with Anorexia nervosa and in healthy, female adolescents on psychophysiological parameters.
- Detailed Description
In a cross-over study design, the subjects (21 female patients with Anorexia nervosa, 20 healthy, female controls) receive footbaths with either ginger, mustard or warm water alone in a randomized order with a wash-out period of at least 1-3 days. The effects of each intervention on the objective warmth generation are measured by infrared thermography, whereas the subjective warmth perception is determined by the 'Herdecke warmth perception questionnaire'. All parameters are determined at specified times (t1 = right before, t2 = right after and t3 = 10 minutes following the footbath), which enables an evaluation based on pre-post-comparisons. The statistical analysis comprises analyses of variances based on linear mixed effects models (after checking for carry-over effects).

- Primary Outcome Measures
Name Time Method Change in 2-Item Warmth Perception Measure (feet) from t1 to t3 right before the footbath (t1) and 10 minutes following the footbath (t3) Self-reported warmth perception at both feet assessed with the "Herdecke warmth perception questionnaire" right before (t1) and 10 minutes following the footbath (t3). Each item is scored 0-4 (0 = cold; 4 = hot), yielding a total between 0 - 8.
