Official title
Effect of Acute Exercise on Sleep Patterns in Patients With PLMS Using a Wearable Device Compared With a Control Group
Overview
The effects of chronic exercise on health promotion, improvement of quality of life, and reduction of the risk of developing chronic diseases such as obesity, diabetes mellitus, cardiovascular diseases, depression, and cancer are well established. In addition, the positive influence of exercise on sleep patterns and sleep quality is widely recognized. However, few studies have addressed the effects of a single session of physical exercise on the circadian cycle and sleep disorders. Regarding Periodic Limb Movement Disorder (PLMD), which is characterized by periodic episodes of repetitive and highly stereotyped limb movements, the scientific literature indicates that the effects of a single session of intense exercise remain insufficiently explored. Therefore, the present study aims to investigate, through a controlled interventional study, the effects of acute exercise on the Periodic Limb Movements of Sleep (PLMS) index. To this end, the study will recruit healthy participants as well as individuals with PLMS to perform acute exercise sessions, followed by a polysomnographic examination and a longitudinal observation period. Throughout the study, participants will use wearable and mobile devices to monitor their physiological patterns. In addition, questionnaires related to sleep, physical exercise, cognitive decline, and depression will be administered to better characterize the study population. Thus, this study aims to generate evidence regarding the influence of acute exercise on sleep patterns in participants with PLMS, as well as to obtain data to support the development of algorithms related to sleep quality, including PLMS detection, which may be embedded in wearable or mobile devices in the future.
Interventions
- Procedure cardiopulmonary exercise test (CPET)
The participant will perform a single session of acute exercise 4 hours prior to polysomnography. On the same day, shortly before the polysomnography, study questionnaires will be administered, and the study devices (watch and ring) will be placed on the participant to record electrophysiological sleep parameters in conjunction with the polysomnography. The following morning, participants will be discharged and will continue to use the devices and complete study questionnaires at home for seven - Procedure Cardiopulmonary Exercise Test (CPET) - Twice
The participant will undergo a single session of acute exercise (CPET) 4 hours prior to polysomnography (PSG). Before the PSG, study questionnaires will be administered, and the participant will wear study devices (smartwatch and smart ring) to collect sleep and physiological data during the night, in conjunction with the (PSG). The next day, participants will be discharged and begin a seven-day free-living period, during which they will continue using the devices at night. After this seven-day
Primary outcome measures
- Sleep parameters measured by polysomnography [Time frame: 7 days]
Eligibility criteria
General Inclusion Criteria:
- Aged 22 years or older;
- Self-reported habitual sleep of at least 5 consecutive hours per night. Specific Inclusion Criteria for the PLMS Group
- Having a prior polysomnography (PSG) showing a PLMS index ≥ 15/h;
- Screening PSG for participants without a PSG in the last 6 months showing a PLMS index ≥ 15/h.
Note: Efforts will be made to ensure that approximately 50% of the sample consists of participants with a PLMS index > 50/h. -
General Exclusion Criteria:
- Pregnant or lactating individuals;
- Presence of dermatological conditions or skin diseases such as vitiligo, lupus, atopic dermatitis, or tattoos on the wrist or fingers that could interfere with optical sensor readings from the smartwatch or smart ring;
- Inability to attend the study PSG sessions;
- Use of medications indicated for the treatment of sleep disorders;
- Current or prior treatment for PLMS management;
- Presence of implanted cardiac devices, such as pacemakers, cardioverter defibrillators, or cardiac resynchronization devices;
- Prior diagnosis of chronic neurological, orthopedic, cardiac, pulmonary, or other clinical conditions that limit the ability to perform physical activity.
Specific Exclusion Criteria for the Control Group:
-Presence of sleep disorders identified on the screening PSG, such as: moderate to severe sleep apnea (apnea-hypopnea index \[AHI\] ≥ 15), insomnia with an Insomnia Severity Index (ISI) score above 14, or PLMS index > 15.-
