Table 1.
Post-exertional malaise (PEM) symptoms precipitated by physical/ cognitive exertion versus emotional distress.
Fig 1.
Range of PEM onset times after physical/ cognitive exertion for subjects (N = 61) with inconsistent timesa.
a These subjects chose the answer “It can vary” when queried about when their PEM began relative to an exertional trigger. Space was provided for them to write down the earliest and latest times their PEM could start. Three subjects noted their onset times fluctuated so frequently they were unable to even give a time range.
Fig 2.
Range of duration of PEM after physical/ cognitive activities for subjects (N = 65) endorsing inconsistent timesa.
a These subjects chose the answer “It can vary” when queried about how long their PEM lasted after physical or cognitive activities. Space was provided for them to write down the shortest and longest times their PEM could be sustained. Five subjects did not give a specific time range.
