Dr. Erik Hoyer is an assistant professor of physical medicine and rehabilitation at the Johns Hopkins University School of Medicine. His clinical interests include musculoskeletal and neurological rehabilitation, injection procedures to manage abnormal muscle tone (spasticity) and electrodiagnostic medicine (EMG).

As deputy director for patient safety he leads efforts to improve patient safety and care at Johns Hopkins, including an initiative called activity and mobility promotion (AMP) to get patients up and moving following surgery.

Dr. Erik Hoyer graduated summa cum laude and received his master's degree in computer science from Brandeis University prior to graduating from the Sackler School of Medicine in Tel Aviv, Israel. He completed his internship in internal medicine at North Shore University Hospital in Manhasset, New York, and subsequently finished his residency in physical medicine and rehabilitation from Johns Hopkins University. He excelled during his residency, receiving the Hopkins Healer award twice, and was selected as a trainee to the Rehabilitation Medicine Scientist Training Program.

Dr. Hoyer’s research interests include quality improvement, brain plasticity, and motor recovery after stroke from both behavioral and neurophysiologic perspectives.

    Research Summary

    Dr. Hoyer conducts research studying motor recovery after stroke from both behavioral and neurophysiologic perspectives under the mentorship of Amy Bastian, Ph.D., and Pablo Celnik, M.D.

    His recent research showed that patients freshly discharged from acute care hospitals with low scores on a standard test that measures how well they perform such everyday activities as moving from a bed to a chair are far more likely to need readmission to a hospital within 30 days than those who score better.
