With a description of treatment such as the one provided above by Goocher (1994), it would not be surprising to learn that, in some jurisdictions, adolescents who have committed sexual crimes have routinely been removed from their homes--regardless of the nature of their crimes--subjected to polygraph and penile plethysmograph (PPG) examinations, aggressively and repeatedly confronted regarding the details of their past sexual crimes, and asked to engage in punishment-based behavioral procedures--designed for adults--that are intended to alter their presumed deviant sexual arousal.
Pulse plethysmography (PPG) was described in the 1930s (1), prior to the development of the pulse oximeter, and the combination of the two approaches in the modern pulse oximeter allows continuous non-invasive monitoring of arterial oxygenation, pulse rate and pulse plethysmograph waveform analysis (2).
