Ecological Momentary Assessment in Patients With Restless Legs Syndrome (DAILY-REST)

November 19, 2025 updated by: University Hospital, Bordeaux

Feasibility, Validity and Clinical Utility of Ecological Momentary Assessment in Patients With Restless Legs Syndrome: a Prospective Study. DAILY-REST

The Restless Legs Syndrome (RLS) is a sensorimotor disorder better characterized by an urge to move the legs at rest. Although treatments are available, many patients experience periods of symptoms relief and exacerbation. Whether this is due to the natural history of the disease or to health-related behaviors of daily life is presently unknown. The primary objective is to examine the feasibility of mobile technology to assess RLS symptoms severity fluctuations in daily life by collecting real-time data. The secondary objectives will be to examine the validity of this technic in the context of RLS and to use these real-time data to identify daily life risk factors for symptom onset or aggravation.

Detailed Description

The Restless Legs Syndrome is a common sensorimotor disorder that disturbs sleep and quality of life. One of the key diagnostic criteria of RLS is the complaint of an irresistible urge to move the legs. This urge to move is often triggered by unpleasant sensations; it occurs at rest, particularly late in the day or at sleep time, and is temporarily relieved with movement. The negative impact on quality of life is profound and the disease is associated with a substantial economic burden. Dopamine agonists show efficacy which is, however, moderate, and many patients do not experience full remission. Tolerance, paradoxical aggravation of RLS symptoms (dopamine-induced augmentation) and impulse control disorders are frequently seen in patients with RLS on dopamine agonists. Therefore, although medications are available, many patients either experience side effects or show treatment response fluctuations with periods of symptoms' remission/alleviation or exacerbation. Whether RLS symptom fluctuation is related to the natural history of the disease (independent of appropriate medical treatment) is presently unknown. Furthermore, it is unknown if such fluctuation may be due to the impact of health-related behaviors in the context of daily life (e.g. physical activity, sleep quality, mood, alcohol consumption, smoking, or specific food intake), although this question warrants further research as any potential association would provide important opportunities for prevention and intervention strategies. For these reasons, the investigators aim to test the feasibility, validity and clinical utility of ambulatory monitoring techniques such as Ecological Momentary Assessment (EMA) to document RLS symptoms severity and risk factors in daily life by collecting real-time data, and by using such information to reduce risk factor exposure and thus improve symptoms. Eligible participants will be given a study-dedicated smartphone to carry with them for a two-week period and will be equipped with wearable actigraph for the same period to monitor activity-rest cycle.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

18 years to 65 years (Adult, Older Adult)

Accepts Healthy Volunteers

No

Description

Inclusion Criteria:

  • Patient over 18 years old and less than 70
  • Any patient with a diagnosis of idiopathic RLS based on medical history and the presence of the 5 RLS diagnostic criteria
  • Normal clinical examination
  • Person affiliated or benefiting from a social security scheme
  • Free, informed and written consent signed by the participant and the investigator (no later than the day of inclusion and prior to any review required by the research).

Exclusion Criteria:

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Feasibility of Ecological Momentary Assessment (EMA)
Time Frame: 14 days after baseline (Day 0)

This outcome measure is composite and will be established by:

  1. Sufficient acceptability of the EMA methodology (at least 50% of patients who are solicited to participate in the EMA study accept the invitation);
  2. Low loss of EMA materials (less than 5% of participants lose or break the study-dedicated smartphone); and
  3. High compliance rate in the completion of daily assessments (participants completing the EMA phase of the study respond to at least half of all programmed assessments, i.e. on average 50% of the total 56 sessions).
14 days after baseline (Day 0)

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
Validity of Ecological Momentary Assessment (EMA)
Time Frame: 14 days after baseline (Day 0)

This outcome measure is composite and will be established by:

  1. A lack of fatigue effect, operationalized by the absence of correlation between the frequency of missing data and the number of days that the individual has participated in the study;
  2. Expected correlations among conceptually-associated EMA variables (i.e., internal validity: hours of sleep should be significantly correlated with energy levels; event negativity should be significantly correlated with the severity of negative affect, etc.); and
  3. Significant correlations between traditional clinical measures of RLS symptoms and EMA-based measures of RLS symptoms (convergent validity). Correlations would also be sought between validated scales (PSQI, ISI, ESS and HADS) and EMA-based measures of RLS symptoms.
14 days after baseline (Day 0)
Risk factors for RLS
Time Frame: Between baseline (day 0) and 14 days after baseline
To examine if specific daily-life behaviors or experiences on any given day as assessed by EMA (activities, environments, psychological states and mood, substance use, food, sleep habits and quality) are prospectively associated with the frequency or severity of RLS symptoms later that evening/night.
Between baseline (day 0) and 14 days after baseline
