“…4). Corey et al (1951) and Boyce (1952) obtained regular low-frequency activity from surface electrodes placed against the bladder wall, while Franksson and Petersen (1953) recorded high-frequency activity from needle electrodes placed in the lateral bladder wall via a cystoscope. We feel that the low-and high-frequency activities these workers recorded occur at each end of the frequency spectrum.…”

“…The first reports of bladder EMG appeared more than half a century ago, and are attributed to Corey et al [9] [10]. It was later shown that signals, similar to those obtained by Corey et al, could be obtained by applying pressure to the electrode, or by small tissue movement [11].…”

In patients suffering from neurogenic detrusor overactivity, continence can be regained by conditional stimulation of the dorsal genital nerve (DGN); that is applying electrical stimulation to the DGN at the onset of an involuntary contraction. For this scheme to work, a sensor capable of reliably detecting the onset of bladder contractions is needed. This article reviews the methods proposed for or associated with detection of bladder contractions, and their applicability to onset detection is assessed. Fourteen methods are described in this review; bladder pressure, urethral sphincter EMG and anal sphincter EMG are the most promising options for onset detection. For all three modalities, however, further research is needed before clinical application becomes viable.

“…In the early 1950s several authors produced a series of reports [3–6] describing a ‘bio‐electric bladder wave’ recorded in humans using bipolar silver‐ball electrodes applied to the urothelium of the bladder wall. This low‐frequency biphasic signal, that was recorded from 105 subjects with normal and dysfunctional bladders, was several seconds long and coincident with intravesical pressure changes, an observation used to support its biological origin, and was said to vary characteristically in different bladder pathologies.…”
