Are laboratory measures reflected in the every day living activities of people with Chronic Fatigue Syndrome (CFS)?

Research in the laboratory setting indicates that people with CFS tend to walk slower and with greater energy cost than matched controls [1] and [2]. This study aimed to investigate if these characteristics were reflected in activities of every day life when monitored using an activity monitor. Over a 24-h period all outcome measures indicate a reduction in activity for those with CFS supporting the translation of laboratory findings into activities of every day activity. Laboratory measures tend to be reflected in the overall activity patterns of people with CFS suggesting that objectively monitoring physical activity patterns is a useful adjunct to laboratory testing.
