Abstract: | This article summarizes the historical development of the algometer in scientific investigations and notes hallmarks in the evolution of the device. The algometer has served as a safe nociceptive stimulus for more than a century. Although the earliest renditions were inexpensive, they were often unreliable and difficult to operate. More modern versions have brought reliability, but at increased expense and complexity. Newer versions have failed to make the device easy enough to use to be practical. The “reinvented” algometer is reliable, less expensive than commercial devices, and easy to build and use. These improvements should allow greater application of the algometer in empirical research and assessment of pain. |
