Effects of a Stress Management Training in Patients With Lymphedema and Obesity During Rehabilitation

Abstract

Abstract: Background: Evidence for behavioral weight loss interventions demonstrates promising effects, but stress management training for weight loss and stress reduction in patients with lymphedema and obesity during rehabilitation has not been investigated yet. Aim: This study aims to examine innovative psychological treatment options for weight loss and stress management through a multifaceted approach in patients with lymphedema and obesity. Method: Seventy-one patients with lymphedema and obesity participating in an existing rehabilitation took part in this clinical trial. Half of them ( n = 36) were allocated to an additional stress management intervention. At the beginning of rehabilitation and the end (after 3 weeks; n = 66) participants’ weight, physical fitness, heart rate variability (HRV), and perceived stress were assessed. After around 8 months ( n = 28) chronic and perceived stress were evaluated again. Results: Irrespective of group allocation, rehabilitation had a positive, but short-term effect on perceived stress ( d = 0.60). Although patients receiving the additional stress management training did neither show a decrease in perceived stress nor an increase of HRV from pre- to post-assessment, they lost more weight and improved physical fitness at post-assessment as compared to the control group. Limitations: A stress-reducing effect of the training was not found, thus questioning the underlying mechanism of the applied intervention. Conclusions: Findings suggest a clinically relevant impact of psychological interventions in patients with lymphedema and a promising pathway for further research.
