A Study on the Use of the MMF07 Foot Massager and Heat Therapy Treatments for Restless Leg Syndrome

Not Applicable

Completed

Conditions: Restless Legs Syndrome

Interventions: Device: MMF07 Foot Massager
Device: Heat Therapy

Registration Number: NCT02526277

Lead Sponsor: Ariane Park

Brief Summary: The purpose of this study is to assess whether the MMF07 Foot Massager and/ or heat therapy may improve symptoms of restless legs syndrome (RLS). It will also assess the effect of the MMF07 Foot Massager and/ or heat on quality of life and sleep in people affected by RLS. Participants will be randomly assigned to one of four treatment groups;

1. MMF07 Foot Massager device

2. Heat therapy

3. Heat therapy and the MMF07 Foot Massage device

4. Neither heat nor MMF07 Foot Massager device (no treatment group)

Detailed Description: Few clinical trials have looked into non-pharmacological, non-invasive treatments for restless legs syndrome, despite reports that massage, baths and vibrations can alleviate RLS symptoms. We would like to assess whether the MMF007 Foot Massager device and/or heat therapy is associated with improved severity of RLS symptoms.

For this study the investigator will enroll 40 participants who have been diagnosed with restless legs syndrome, who will be followed over the course of four weeks and asked to complete two in person study visits. In the study the investigator is comparing the use of the MMF007 Foot Massager device and/ or heat therapy to a non treatment group to assess if the symptoms of RLS improve.

Arm && Interventions

Group	Intervention	Description
MMF07 Foot Massager device	MMF07 Foot Massager	Participants randomized to the MMF07 Foot Massager device arm will be provided the MMF07 Foot Massager device and instructed to set this device at setting 3, then increase or decrease the setting to their desired level of comfort, to be used for 30 minutes at bedtime.
MMF07 Foot Massager device and heat therapy	MMF07 Foot Massager	Participants randomized to both the MMF07 Foot Massager device and heat therapy will be provided both the MMF07 Foot Massager device and electric heating pad. Participants will be instructed to set the MMF07 Foot Massager device at setting 3, then increase or decrease the setting to their desired level of comfort. They will also be instructed to use the electric heating pad at a medium setting at the same time for 30 minutes at bedtime.
Heat therapy	Heat Therapy	Participants randomized to heat therapy will be provided an electric heating pad and will be instructed to use this pad at a medium setting for 30 minutes at bedtime.

Primary Outcome Measures

Name	Time	Method
The International Restless Legs Severity Scale	4 weeks	Participants answer a series of 10 questions each of which have values ranging from 0 to 4, the points are then added together. Higher values are associated with more severe symptoms; up to a maximum severity score of 40 points and a minimum severity of 0 points.

Secondary Outcome Measures

Name	Time	Method
The Restless Legs Quality of Life Questionnaire	4 weeks	Participants answer a series of 18 questions that are scored such that lower scores indicate worse quality of life. The scoring process for the RLSQoL is relatively complicated. Items 1-5, 7-10, and 13 use scales ranging from 1 to 5, with lower scores indicating a greater frequency and interference of restless legs syndrome. The total score for these items is converted to a value between 0 and 100 using an algorithm provided along with the scale. Items 6 and 16-18 require respondents to indicate how many days in the previous month or hours in the previous day they have been able to complete certain activities or have had their daily functioning interfered with. These items are scored as continuous variables (for example, ranging from 0 to 28 days for questions regarding the number of days per month). Items 11, 12, 14, and 15 are categorical variables, where a response of "yes" receives (a 1), a response of "no" receives (a 2), and a response of "not applicable receives (3a).
Changes in Sleep as Measured by the Medical Outcomes Sleep Study Scale at Week 4	4 weeks	Participants answered a series of 12 questions assessing sleep, with values ranging from 1 to 6, and an additional dichotomous indicator of optimal sleep. All items are scored so that a high score reflects more of the attribute implied by the scale name. Each item is then converted to a 0 to 100 possible range so that the lowest and highest possible scores are set at 0 and 100, respectively. In this format, scores represent the achieved percentage of the total possible score. Reference: Spritzer, K. L. \& Hays, R. D. (2003, November).
