ABSTRACT
OBJECTIVES: Exercise has been recommended to enhance sleep. However, there is a paucity of studies investigating the relationships between exercise and sleep problems in patients with bladder cancer. The authors explored the effects of a single bout of light-intensity walking on the sleep quality of patients with bladder cancer who have sleep disorders. DATA SOURCES: A total of 14 patients with bladder cancer with sleep disorders were recruited for this trial. The participants were randomly assigned to the walking or control condition in a cross-over design to explore the effects of a single light-intensity walking session on objectively measured sleep quality. A two-way repeated measures analysis of variance and a nonparametric permutation test were used to examine intervention effects. Twelve participants (85.7%) completed the trial. A significant groupâ¯×â¯time interaction for sleep latency (Pâ¯=â¯.023) was identified. The pairwise comparison showed significant results (Pâ¯=â¯.012) for the difference between the post-test sleep latency and the pre-test. No significant groupâ¯×â¯time interactions were observed for the remaining seven sleep parameters. Additionally, only the main effects of time on length of awakening and time in bed were significant (P < .001). CONCLUSION: A single bout of light-intensity walking has a positive effect on shortening the sleep latency of patients with bladder cancer who have sleep disorders. IMPLICATIONS FOR NURSING PRACTICE: Oncology nurses can encourage patients with bladder cancer to exercise, even light-intensity walking, which may improve sleep quality.
