Clinical impact of physical exercise on sleep disorder as assessed by actigram in patients with chronic pancreatitis: a study protocol for a randomised controlled trial

In most chronic pancreatitis (CP) cases, malabsorption, pain, and weight loss are the leading clinical symptoms, which significantly worsen the quality of life (QOL) and decreased QOL in patients with CP can cause sleep disorder. There is a growing body of evidence that recognises the favourable effects of physical exercise (PE), however, there are limited data currently available concerning patients with CP undergoing PE. Actigram is a device for gathering objective sleep/awake data in the natural sleeping surroundings over an extended time period. In this study, we will aim to prospectively investigate the effect of PE on sleep disorder as assessed by actigram in patients with CP.

This study is a non-double-blind randomised controlled trial. Study participants will be randomised into the PE group and the control group. When registering patients, precise assessment for nutritional status and daily physical activities will be undertaken in each study patient. In the PE group, physical activities equal to or higher than walking for 60 min/day should be strongly recommended. Sleep quality using actigram will be prospectively compared in the two groups. The primary endpoint is the activity index in actigram at 12 weeks.

Ethical approval for the study was granted by the Institutional Review Board at Hyogo College of Medicine (approval number 2767). Results will be presented at relevant conferences and submitted to an appropriate journal following trial closure and analysis.
