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.
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.
