An accurate and reproducible technique was used for estimation of scalp impedance (1 kHz) in each of eight rat cadavers, maintained at 9.0±0.7°C, during the I to 144 hour post-mortem period.
Scalp impedance increased non-linearly, and in a bimodal manner, between 24 and 144 hours post-mortem.
The relationship between scalp impedance and post-mortem interval, and the degree of individual variation in the time course of impedance change, were such that scalp impedance is unlikely to be a suitable tool for estimation of time since death.
