Frank H. Krusen (1898 - September 16, 1973) was an American physiatrist. He is regarded as a "founder" of the field of physical medicine and rehabilitation. He founded the first Department of Rehabilitation at Temple Hospital in 1928. Physiatrists remember his scholarly contributions, most notably through his numerous contributions to the medical literature on the use of therapeutic modalities in medicine, and his foundational textbook, Physical Medicine, published in 1941, and subsequently titled, Krusen’s Handbook of Physical Medicine and Rehabilitation (the 4th and last edition was published in 1990) 1]. Dr. Krusen was the driving force behind the establishment of the first residency program in Physical Medicine at Mayo Clinic in 1936. He was also a charter member of the American Academy of Physical Medicine and Rehabilitation (AAPM&R) and served as its president from 1941-1942. His focused on the field on education, research, and collaboration with other colleagues in medicine and rehabilitation services, a framework for professional activities that remains relevant for PM&R in the 21st century.
Frank Hammond Krusen was born in Philadelphia, Pennsylvania, in 1898. His father was a professor of obstetrics and gynecology at Jefferson Medical College who also served as the director of public health in Philadelphia. His mother was a practicing Quaker, and young Frank grew up in a family that prized education and instilled in him the value of service to the community. Therefore, it was no surprise that Krusen chose a career in medicine, and, when he graduated from Jefferson Medical College in 1921, he pursued further training in general surgery.
Krusen's career trajectory deviated from a predictable course when he was diagnosed with pulmonary tuberculosis during his surgical residency training. Forced to withdraw from training, he spent 5 months at the Cresson Tuberculosis Sanitorium in central Pennsylvania. Some would say it was this experience with the “rest cure” and “fresh air” used for treating tuberculosis at the time that stimulated his interest in the use of physical agents in medicine. Krusen also was judged unable to continue in surgical training because of a vulnerability to ether fumes. In any case, when Krusen was well enough to return to his medical training, he changed his career path to physical medicine, a branch of medicine that was just beginning to develop in the United States.
