Our Story

Founded to progress research into Leg Movements During Sleep

Tanzen Medical was founded through a collaboration of UMBC Engineering Professors and Johns Hopkins Sleep Physicians. Our goal has always been to create an accessible method for multi-night characterization of leg movements during sleep (LMS) for aid in the diagnosis and treatment management of sleep movement disorders (RLS, PLMD, RBD, and ADHD).

Tanzen is a German word meaning "to dance".

Expert Opinions

What are experts saying about RestEaze?

"As you know there are many children who have very restless sleep including many with ADHD and RLS. [RestEaze] would help us evaluate both diagnosis and treatment efficacy."
Lourdes M. DelRosso, M.D., MS
Sleep Specialist, Seattle Children's Hospital
"We see many children with restless sleep and sleep related movement disorders. It would be very helpful to be able to monitor these children to evaluate the need for treatment and to assess short and long-term treatment outcomes. [RestEaze] could help guide treatments. Currently, there are limited tool to guide the treatment. Your monitor would address a significant unmet need for pediatric sleep medicine"
Narong Simakajornboon, M.D.
Cincinnati Children's Hospital
"[RestEaze] will meet a critical need for pediatric sleep medicine, with multiple-night, at-home sleep evaluations specifically designed for evaluating restless sleep in children. Your system enables evaluation of both diagnosis and treatment efficacy."
Daniel Picchietti, M.D.
FAASM, Fellow, American Academy of Sleep Medicine
"The RestEaze device is easy to use and comfortable to wear while providing a remarkable level of detail on leg movements throughout the sleep period."
