A pilot study to examine the feasibility and effects of a home-based aerobic program on reducing fatigue in children with acute lymphoblastic leukemia.

BACKGROUND Fatigue is one of the most frequent symptoms experienced by children with cancer during treatment. Effective management of fatigue is essential for improving children's quality of life. OBJECTIVE The aim of this study was to examine the feasibility of a home-based aerobic exercise intervention to reduce fatigue in children with acute lymphoblastic leukemia (ALL). METHODS A 6-week home-based aerobic exercise intervention was implemented for children who were in the intervention group, whereas patients in the control group received routine care. Multivariate analysis was used to examine the effects of the aerobic exercise intervention on the children's self-reported levels of fatigue at posttest and 1-month follow-up. Two types of analysis were used: intent-to-treat analysis and per-protocol analysis. RESULTS This study was conducted with 22 children with ALL: 12 in the intervention group and 10 in the control group who were matched by age and sex. For per-protocol analysis, the finding indicated that children who received the exercise intervention reported significantly lower "general fatigue" subscale than those in the control group at the 1-month follow-up measurement. For intent-to-treat analysis, the findings indicated that there were no intervention and time effect for any of the 3 fatigue subscales at either posttest or 1-month follow-up. CONCLUSION The finding indicated that the exercise program is feasible and warrants being tested in a clinical trial with a much larger sample of children for ALL. IMPLICATIONS FOR PRACTICE It suggests that a home-based exercise program may reduce fatigue for ALL children who are undergoing maintenance chemotherapy.
