Nonpharmacological interventions for myalgic encephalomyelitis/chronic fatigue syndrome (ME/CFS) often emphasize gradual increases in activity to promote improvement in physical functioning and fatigue.
The energy envelope theory may provide a framework for understanding the relationship between changes in activity level and outcomes for patients with ME/CFS. [Note: for one explanation of this theory, see Bruce Campbell's article "Finding Limits: The Energy Envelope," on the CFIDS & Fibromyalgia Self-Help website.]
This study examined the relationship between energy envelope and changes in activity after nonpharmacological interventions in a sample of 44 adults with ME/CFS.
Results showed that those who were within their energy envelope before treatment showed more improvement in physical functioning and fatigue compared with those outside of their energy envelope.
These findings suggest that an assessment of perceived available and expended energy could help guide the development of individualized nonpharmacological interventions for people with ME/CFS.
