Revolutionizing Muscle Health Diagnostics

Empowering healthcare professionals with the Muscle Assessment Test (MAT) to diagnose and treat disorders resulting from low muscle mass and reduced strength, including diagnosing the contribution of low muscle mass to mobility disability (ICD 10 code R54)

About MyoCorps

MyoCorps is at the forefront of muscle health diagnostics, leveraging cutting-edge science to combat disorders of mobility in adults over 60 that results from low muscle mass. Our patented Muscle Assessment Test (MAT) uses the innovative D3-creatine dilution method to provide accurate, non-invasive muscle mass measurements—ensuring targeted and effective treatments for disorders of strength, performance and mobility.

Why Address Mobility Disability?

Mobility disability is a well-recognized geriatric syndrome (ICD 10 code R54) that affects millions of older adults and leads to reduced independence, chronic diseases, and higher mortality rates. Common features of mobility disability include:

Low muscle mass has been identified as a critical factor underlying these challenges.

Introducing MyoCorps’ Muscle Assessment Test (MAT)

The MAT offers a breakthrough in diagnosing mobility disability resulting from low muscle mass through a simple, non-invasive urine test. It measures muscle mass with unparalleled accuracy, enabling healthcare professionals to:

Healthcare provider identifies a patient with a mobility disability (diagnosed by questionnaire) and orders a MAT. The MAT ‘kit” contains detailed instructions of how to administer the test, collect a urine sample, and send it (via overnight mail) to MyoCorps. MyoCorps will provide a detailed description of the result and confirm if the patient has low muscle mass.
