Can pacing self-management alter physical behavior and symptom severity in chronic fatigue syndrome? A case series.
Given the lack of evidence in support of pacing self-management for patients with chronic fatigue syndrome ( CFS ) , we examined whether physical behavior and health status of patients with CFS would improve in response to a pacing self-management program . We performed an observational study of pacing self-management in seven CFS patients using a single-case study design . Stages A1 and A2 ( 7-day assessment periods ) of the A1-B-A2 design corresponded to the baseline and posttreatment measurements of physical behavior ( real-time activity monitoring ) and health status ( self-reported measures ) , respectively . Stage B ( 3 weeks of treatment ) consisted of three individual treatment sessions of pacing self-management . When comparing pre- versus posttreatment data , we found that the patients ' ability to perform daily activities and the severity of their symptom complexes were improved ( p = 0.043 ) . Concentration difficulties , mood swings , muscle weakness , and intolerance to bright light improved as well . A statistically significant decrease in the mean time spent doing light activity ( <3 metabolic equivalents ) was observed , but a change in the way physical activity was spread throughout the day was not . We found that 3 weeks of pacing self-management was accompanied by a modest improvement in symptom severity and daily functioning . The outcome of the present study calls for a r and omized controlled clinical trial to examine the effectiveness of pacing self-management for people with CFS
