Clinical Trial

Introduction: Restless legs syndrome (RLS) is a neurological disorder that causes unpleasant sensations and a need or urge to move the legs. The sensations are often described as burning, creeping, tugging, or feeling like insects are crawling inside the legs. The symptoms commonly develop when a person is at rest and tries to relax or go to sleep. RLS inhibits people from sleeping, which can lead to depression and a poor quality of life.

Until now, potent drugs including opioids, central nervous system depressants, and dopamine agonist have been used to ease symptoms, but each of these is accompanied by several negative side effects. Examples include dizziness, nausea, vomiting, and the risk of addiction.

restiffic is a drug-free solution to RLS. It is a revolutionary foot wrap consisting of a compressive pad and a hook and loop system, designed to exert a gentle, relaxing pressure on the abductor hallucis and flexor hallucis brevis muscles in the foot. This pressure reduces the symptoms of RLS.

Method: In 2013, a clinical trial was administered to test the efficacy and safety of restiffic. It was a single arm, open label clinical trial with a repeated measures design. The study population consisted of otherwise healthy adults, mean age 51.5 years (range 30 to 75 years), diagnosed with moderate to severe primary RLS.

Efficacy was measured using the International RLS Study Group (IRLSS) Rating Scale, with scores ranging from 0 to 30 (30 being the most severe), and the physician-generated Clinical Global Impression (CGI) Scale, measuring severity, improvement, and Efficacy Index (EI). Safety was assessed by recording adverse events, analyzing the severity, and the relationship to the restiffic device.

During the study, patients recorded their RLS symptoms over 8 weeks. After one week of observation without treatment, patients were given a restiffic device for Weeks 2 through 4. The device was removed for Week 5, and returned to the patients for Weeks 6 through 8.

Results: In Week 1, all patients exhibited severe symptoms of RLS, with an average patient IRLSS score of 25.05 (“severe”). When patients began wearing the device, many experienced relief after just 24 hours of therapy (Day 8), with the mean IRLSS score decreasing from 25.05 to 16.94 (“moderate”) in just one day. Patients’ RLS symptoms decreased significantly and continually over the course of the next three weeks, with an average IRLSS scores at the end of Week 4 of 10.88 (“mild”). When the device was removed for Week 5, patients once again experienced severe RLS symptoms, though not as high as initially seen in Week 1. In Weeks 6 through 8, patients again showed significant and continued decreases in their RLS symptoms while wearing the restiffic device.

Over the course of the trial, patients exhibited an average 69% reduction in the severity of their symptoms, with the average patient IRLSS score at the end of the trial being 7.83, for an overall reduction of 17.22 points. This represents an improvement from “severe” to “mild” symptoms.

Based on the study results and the low-risk nature of the device, restiffic was cleared by the FDA for prescription use to support positive RLS diagnosis.

RLS Symptom Decrease

Key Statistics:

  • 97% of patients experienced a decrease in the severity of their RLS symptoms.
  • Patients exhibited 69% reduction in the severity of symptoms after 6 weeks of using restiffic.
  • restiffic was shown to be 40% more effective than the leading drug treatment for RLS.
  • Physicians reported observing no side effects in 93% of patients.
  • Only 9 Adverse Events definitely related to restiffic occurred in seven patients. These included pain, tingling, and irritability. All AEs were relieved by loosening the device’s straps.
