Energy Envelope Theory
The Energy Envelope Theory is a self-management tool to reduce symptom severity and the frequency of relapses. This theory suggests that because variations in day-to-day energy levels are often unpredictable in people with ME/CFS, they are to assess their perceived energy levels on a daily basis (or in smaller time increments, as needed) and use that level to gauge their energy expenditure for the day. It encourages people with ME/CFS to accept their daily energy limitations and not exceed or fight them.
Some practitioners of the Energy Envelope Theory take the concept further by recommending that people with ME/CFS do less than their perceived energy would allow in order to have energy left over for recovery.
Under the Energy Envelope Theory, treatment programs that recommend a steady increase in daily activity are discouraged because the person with ME/CFS may exceed the amount of energy available for that day, thereby initiating post-exertional malaise or an increase in symptoms. Those that stay within their daily "envelope" of energy, not only have fewer symptoms but often recover to a higher functioning level than those who don't.
Patient experiences with the Envelope Theory[edit | edit source]
- The Just ME blogger, Sally Burch, has written about self-pacing and the energy envelope in a post called "Play-Up & Lay-Up" not "Boom & Bust".
- Bruce Campbell, PhD, has included the Envelope Theory in chapter 7 of his manual, Recovery from Chronic Fatigue Syndrome: One Person's Story
