ABSTRACT

Formal testing of sensation as part of the neurological examination followed the improvements in examination techniques as well as advances in neuroscience. By the 1890s, the observation that temperature sense was frequently impaired at the same time that pain was appreciated led to the supposition that the two paths traveled closely. Through the works of Brown-Séquard and Edinger the existence of a crossed afferent tract was verified. The distinction between two sensory pathways was clear by 1898, when van Gehuchten reported a case of syringomyelia and suggested that the pain and temperature fibers were carried anterolaterally and the position sense fibers carried posteriorly in the spinal cord. Many authors describing patients with tabes dorsalis suspected the posterior columns of the spinal cord played a key role in position sense. It is difficult to determine in the 19th century who first employed the use of movements of joints as a test for proprioceptive function; however, Bell in 1826 recognized what he termed a sixth sense, which later was characterized as proprioceptive function. Goldscheider went on to report the degrees of movement that were considered normal for each joint. Although vibratory sense had been described by Cardano and Ingrassia in the 16th century and tests had been developed by Rinne and Rumpf by the 19th century, it was not until 1903 that Rydel and Seiffer found that vibratory sense and proprioceptive sense were closely related and that both senses were carried in the posterior columns of the spinal cord. By 1955, the sensory examination included tests for light-touch, superficial pain, temperature, position sense, vibration, muscle (deep pain), and two-point discrimination. Tests for these sensibilities still remain in use. We will review the origins of the understanding of sensation, which ultimately led to the development of the sensory examination. We will highlight individuals who made important discoveries and observations, as well as review the history of each of the elements of the sensory examination.
