Modern deep brain stimulation (DBS) devices typically enable the programmer of the device to specify the pulse amplitude, the number of pulses delivered per second and the duration of each pulse e i.e. current, frequency and pulse width, respectively. Some devices also enable considerable control over the administration of the electric charge, via accurately-powered segmented electrodes. A DBS programmer may also consider the total electrical energy delivered (TEED) per second by such a device. TEED (1s) was used in 2002 by Moro et al. [1], and subsequently modified in a 2005 letter by Koss et al. [2]. Koss and colleagues provided a mathematical derivation concluding:
