Benefits of earning the RMSKS credential after passing the MSKS examination

We surveyed some of our sonographers, and they explained to us that earning the RMSKS credential has helped them to: 

  • Assess bone, muscle, tendon, ligament, nerve, and soft tissue pathology and tears and assist with interventional procedures, injections, and ultrasound-guided carpal tunnel release. 
  • Increase their employment opportunities and work in orthopedics, radiology, rheumatology ultrasound,  and sports medicine, and more! 
  • Provide value and specialized knowledge to their hospitals or clinics
  • Secure employment because not many sonographers have obtained the RMSKS credential because the program is very new
