We read with interest the recent study, “Effect of Sensory Stimuli on Restless Legs Syndrome: A Randomized Crossover Study” by Rozeman et al.1
Their observations are consistent with our two, recently published, prospective, randomized, double-blind, parallel design clinical trials.2,3 In these trials treatment consisted of patients placing a vibrating pad (Sensory Medical, Inc., San Clemente, CA) under their thigh or calf, in bed, at the time of an RLS attack. Sleep improvement was significantly greater for patients assigned a vibrating pad than those assigned a sham pad2 and was not significantly different than improvement from FDA-approved RLS drugs.3
Vibration provides a counterstimulus during an RLS attack. However, unlike patient-applied counter-stimulation—such as leg rubbing and twisting, standing, or walking—vibration is compatible with sleep.
It appears that sensory input therapies may play a future role in the relief of RLS symptoms.
