Overview
To explore the effectiveness of EMDR therapy treatment in reducing symptoms of chemotherapy-induced conditioned nausea and vomiting in (former) patients with cancer.
Description
Conditioned nausea and vomiting is a common side effect of anti-cancer treatment, and while strategies like antiemetics exist, their effectiveness is limited. Conditioned nausea and vomiting can possibly be addressed through Eye Movement Desensitization and Reprocessing (EMDR) therapy. EMDR therapy is a therapeutic intervention, proven to be effective in the treatment of post-traumatic stress disorder (PTSD), and promising in treating a range of other conditions. At the UMCG, EMDR therapy is used on a small scale to treat conditioned nausea with positive results, although more rigorous research is needed to fully establish its efficacy. This study aims to explore the effectiveness of EMDR therapy treatment in reducing symptoms of chemotherapy-induced conditioned nausea and vomiting in (former) patients with cancer.
