Company profile
researched Aug 2026MedRhythms develops next-generation neurotherapeutics intended to improve walking, mobility and related functional outcomes in people with neurologic injury and disease. Its products are built on rhythmic auditory stimulation (RAS), an evidence-based intervention in which music is used to drive auditory-motor entrainment — synchronization of the auditory and motor regions of the brain — to produce therapeutic benefit. The company's platform combines sensors that capture real-time gait data, software and clinical algorithms, and personalized musical stimuli delivered through headphones; the algorithms continuously assess a user's entrainment and walking quality and adjust the auditory stimulus toward a defined clinical goal.
The underlying software platform, EntrainRx, standardizes application development, data capture, processing, storage and rhythmic stimulus delivery so that new neurotherapeutics can be designed, tested and iterated across conditions. MedRhythms states two products are available by prescription nationwide: InTandem, for ambulatory adults with stroke walking impairments, and MOVIVE, for people with Parkinson's disease. Its disclosed pipeline includes MR-001 (stroke, pivotal trial), MR-005 (Parkinson's disease, feasibility), MR-004 (multiple sclerosis, feasibility), MR-010 (post-acute stroke, feasibility), MR-012 (functional neurological disorder, feasibility), MR-009 (aging in place, design and proof of concept) and MR-C-001 (cognition, design and proof of concept).
A related in-person services arm, MedRhythms Therapy, delivers Neurologic Music Therapy in outpatient, in-home, community and telehealth settings in partnership with rehabilitation hospitals including Spaulding Rehabilitation Hospital, Burke Rehabilitation Hospital and HHM JFK Johnson Rehabilitation, addressing populations such as traumatic brain injury, stroke and neurodegenerative disease.
Founding story
MedRhythms was founded in 2015. Co-founder and CEO Brian Harris, a board-certified Neurologic Music Therapist and one of approximately 350 professionals globally with advanced training in the clinical application of neuroscience and music, started MedRhythms as a Neurologic Music Therapy practice at Spaulding Rehabilitation Hospital. In 2017, in response to growing demand from people with neurologic gait disorders and the limited number of trained clinicians, the company identified technology as a more scalable way to deliver the intervention. Owen McCarthy is the other co-founder.
Business model
MedRhythms develops prescription digital therapeutics regulated as medical devices, taking products through feasibility studies, pivotal trials and regulatory clearance before commercialization. Its devices are made available to patients by prescription. The company also operates an in-person Neurologic Music Therapy service delivered in partnership with rehabilitation hospitals across outpatient, in-home, community and telehealth settings.
Products are distributed on a prescription basis to patients, alongside clinician-delivered Neurologic Music Therapy services provided through hospital partnerships.
Traction
Two devices, InTandem for stroke and MOVIVE for Parkinson's disease, are available by prescription nationwide. The chronic stroke product holds FDA breakthrough device designation and has been evaluated in a multi-site randomized controlled trial. MedRhythms Therapy reported passing 10,000 treatment hours, and the company cites over 30,000 hours of direct patient care delivered using RAS and related music interventions.
Latest developments
MedRhythms markets InTandem for stroke walking impairment and MOVIVE for Parkinson's disease as prescription products available nationwide, while advancing feasibility-stage programs in multiple sclerosis, post-acute stroke and functional neurological disorder and earlier-stage programs in aging in place and cognition.
▸Full profile — market position, technology, go-to-market, geography, history, risks & controversies
Market position
MedRhythms describes itself as operating the most comprehensive Neurologic Music Therapy practice in the United States and characterizes its offering as the world's first prescription music platform. It received FDA breakthrough device designation for its digital therapeutic for chronic stroke walking deficits and has been listed among private medtech companies to watch by MD+DI.
The company pairs real-time gait sensing with patented algorithms and licensed commercial music rather than generic metronomic cues, and cites a collaboration with Universal Music Group giving patients access to a broad music catalog. It grounds product design in more than 30 years of academic research on rhythmic auditory stimulation, over 50 published clinical studies, and more than 30,000 hours of direct patient care delivered by its own clinicians.
Technology
The EntrainRx software platform pairs wearable sensors clipped to a patient's shoes, which capture real-time gait data, with patented clinical algorithms that curate, augment and individualize music-based interventions in real time. The approach digitizes rhythmic auditory stimulation to drive auditory-motor entrainment, which the company states can enhance neuroplasticity and improve walking outcomes over time. Music content is screened and customized through a patented process that first analyzes tracks for therapeutically relevant characteristics. The platform standardizes data capture, processing, storage and stimulus delivery to support development of additional indications.
Go-to-market
Products reach patients by prescription and are supported by clinical trials conducted with institutions including Cleveland Clinic, Massachusetts General Hospital and leading rehabilitation hospitals. The company partners with rehabilitation hospitals for in-person therapy services and maintains stroke, Parkinson's, aging and multiple sclerosis scientific advisory boards as well as a patient advisory board.
Adults with walking and mobility deficits caused by neurologic injury or disease, including chronic and acute stroke, multiple sclerosis, Parkinson's disease, traumatic brain injury and functional neurological disorder, reached through prescribing clinicians and rehabilitation hospitals.
Geography
Headquartered in Portland, Maine, with a hybrid team distributed across the United States. Hospital partnerships and product availability are U.S.-based, and the company states an intent to serve patients internationally.
History
After beginning as a Neurologic Music Therapy clinical practice, MedRhythms expanded into device development and clinical research. It initiated a multi-site randomized controlled trial for its post-stroke walking rehabilitation device at leading U.S. rehabilitation hospitals in October 2019, advanced multiple sclerosis and Parkinson's disease programs in January 2020, launched a Parkinson's disease clinical trial and expanded into aging in April 2021, initiated an acute stroke trial in April 2021, and announced a neuroimaging study in multiple sclerosis with Massachusetts General Hospital in May 2021. It raised a $25 million Series B in July 2021, bringing total private financing to $34 million at that time, and subsequently commercialized InTandem for stroke and MOVIVE for Parkinson's disease.
Risks & controversies
Several pipeline programs remain at feasibility or proof-of-concept stage and depend on clinical trial results and regulatory clearance before commercialization.
