Commentaires : | The reflex hammer has its roots in the earlier medical practice of percussion. As early as 1761, percussion was being used as a clinical assessment technique to determine the conditions of underlying organs. This discovery led to the design, development and widespread use of percussion hammers in medical practice. During the second half of the nineteenth century, a wide variety of percussion hammers were developed that resembled tomahawks, battle axes and magic wands and were made from materials such as brass, whalebone, wood, rubber, lead and ebony. During this same time period, the concept of the reflex action was being studied. Marshall Hall developed the model of the reflex arc that established reflexes as part of the neurophysiologic examination. With the lower leg hanging freely off the edge of the bench, the knee jerk is tested by striking the quadriceps tendon directly with the reflex hammer. The reflex hammer is also used to test reflexes in the biceps, triceps, and ankle. This reflex hammer is part of a collection of medical and office equipment used by Dr. L George Dewar in his office in "Leighwood", O'Leary, Prince Edward Island, for the periods of 1947-1971 and 1997 until his death in 2003. Dr. L. George Dewar was born in New Perth, Prince Edward Island in 1915. He obtained a Medical Degree from Dalhousie University, Halifax, Nova Scotia in 1943 and a diploma in Public Health from the University of Toronto in 1946. The following year he moved to O'Leary, Prince Edward Island where he established a family medical practice which was in operation for over thirty years. Dr. Dewar ran his medical practice from "Leighwood", or the Doctors' Home as it was better known. This homestead was built in 1886 by Dr. Donald McLachlan, the first physician in O'Leary, and was owned and occupied by six doctors and their families for one hundred and seventeen years. From 1971 to 1997, Dr. Dewar practiced medicine at the O'Leary Medical Clinic which he co-founded with Dr. Charles Dewar. |
