Interventions

Balance-ACT is an ACT-based psychological intervention specifically designed for people with PCS/LC. Balance-ACT will use ACT techniques and mindfulness and will focus on establishing a balance psychologically and physiologically and regulating homeostasis. More specifically, Balance ACT will aim to regulate behaviours such as sleep, stress and activity, which can subsequently have an impact on homeostasis and physiology. Balance-ACT will also encourage people to live a values-based life and set goals according to their values.
