Aerobic Exercise on Improving Sleep in Systemic Lupus Erythematosus.

Not Applicable

• Conditions: Sleep Disorders; Systemic Lupus Erythematosus
• Interventions: Other: Control Group; Procedure: Aerobic Exercise

• Registration Number: NCT02037971
• Lead Sponsor: Federal University of São Paulo

Brief Summary

The purpose of this study is to determine the effectiveness of exercise training on improving sleep in patients with systemic lupus erythematosus.

Detailed Description

This study will test the effectiveness of aerobic exercise on improving sleep in patients with systemic lupus erythematosus. The subjects will do treadmill 2 times per week, from 15-20 min. with low to moderate(55-65% maxCF) intensity exercise, so 30 min. until 4ª week. From the 5ª to 8ª week they will be able to make greater efforts to 35-40 min. totalizing 16 weeks. The control group will not do exercise and will receive education class about disease, health, sleep, 1 time per month.

Arm && Interventions

Group	Intervention	Description
Control Group	Control Group	A non-exercise group will receive regular educational information relating to their condition.
Aerobic Exercise	Aerobic Exercise	Subjects will follow one defined exercise process, according their cardiopulmonary exercise test, during 16 weeks, two times per a week.

Primary Outcome Measures

Name	Time	Method
Sleep Efficiency	16 weeks	Sleep efficiency will be evaluate with actigraph. The subject will use it for 15 days before the period of exercise, 15 days at the start of the period of exercise, and then 15 last days in the period of exercise.; Complementing the information collected by the device, the patient will complete a sleep diary, with schedules of activities such as: time they go to bed, time they fall asleep, time they get up, times they remove the device (which is not waterproof), times they replace the device, and times they wake up from naps.
Sleep quality	16 weeks	The Pittsburgh Sleep Quality Index (PSQI) is a questionnaire that includes 21 items that assess the quality of sleep during a one-month period.; The subject will be asked it, before, during and after the period of exercise. The questionnaire is divided into seven components: subjective sleep quality, sleep latency, sleep duration, sleep effectiveness, sleep disorder, use of sleep medication, and daytime dysfunction.; On the PSQI a score ≥ 5 indicates poor quality of sleep, and ≤ 4 indicates good quality of sleep.

Secondary Outcome Measures

Name	Time	Method
Quality of life assessment	16 weeks	Subjects' health will be evaluated utilizing the questionnaire 'Short Form (36) Health Survey' (SF-36).
Disease activity assessment	16 weeks	Subjects' disease activity will be evaluated using SLEDAI, a modification of the Systemic Lupus Erythematosus Disease Activity Index (SLEDAI). It is a list of 24 clinical and laboratory items which assess and quantify disease activity. A subject's score has to be ≤ 8 to be considered for the study.
Restless Legs Syndrome gravity assessment	16 weeks	Subjects' Restless Legs Syndrome (RLS) gravity will be assessed using the International Restless Legs Syndrome Rating Scale. It consists in 10 questions that evaluate the severity of symptoms and impact of the disease on daily life activities.
Fatigue assessment	16 weeks	Subjects' fatigue will be evaluated using the Visual Analogue Scale for overall fatigue (VAS-fatigue) which consists of a numeric range from 1 to 10, where 1 represents light fatigue and 10 represents intense fatigue.
Pain assessment	16 weeks	Subjects' pain will be assessed utilizing the Visual Analogue Scale (VAS) which consists of a numeric range from 1 to 10, where 1 represents light pain and 10 represents intense pain.
