Factor analysis was conducted and a mean composite score of fatigue-sleepiness-exhaustion was created.
Before Ex1 (8:40), immediately after Ex1 (10 00), immediately before Ex2 (14 00, 4 h after Ex1), 4 h after Ex2 (19 00), and 24 h after the onset of Ex1 (9:00), maximal power for bench press, jump performance, blood variables, scores of fatigue, and muscle soreness were evaluated.
Scores of fatigue Whether different scoring patterns were present in the sample was also examined.
Figures 1 and 2 present the unadjusted means of factor scores of fatigue for patients' self-reports and parents' proxy-reports, respectively.
Scores of fatigue The flowcharts further illustrated that each patient had different fatigue scores, both at an individual level of fatigue, as well as different scores on the dimensions.
The symptom scales and single-item measures were generally positive skew distribution and the modal scores were frequently 0 (i.e., no symptoms), except that the modal scores of fatigue and mode were 33.3.
Information about the outcome variables at the three assessments are listed in Table 2. Scores of fatigue severity, functional impairment and psychological distress significantly decreased at post-treatment and follow-up assessment compared with the pretreatment assessment.
Figure 3 compares the unadjusted mean scores of fatigue change patterns for patient self-reported data over time for those patients who ever received corticosteroids and those who did not (descriptive data for fatigue factor scores are not presented here but are available on request).
The Bristol Rheumatoid Arthritis Fatigue Multi-Dimensional Questionnaire (BRAF MDQ) [ 44] consists of 20 items including four sub-scale scores of physical fatigue, living with fatigue, cognitive fatigue and emotional fatigue.
Exercise significantly increased score of subjective fatigue (main effect for time: P = 0.00, F = 64.26, partial η 2 = 0.87).
The only association found was for the score of the "Fatigue" dimension that turned out to be lower for those patients with surgical problems (4.84 ± 1.94 versus 6.08 ± 1.01).
