Intravaginal electrical stimulation (IVS) induces a profound bladder inhibition and is successful in the treatment of incontinence due to detrusor instability. In this experimental study in cats, direct recordings of the efferent activity in thin hypogastric and pelvic nerve filaments to the bladder were used to analyze the neuronal mechanisms underlying(More)
Using a new device for intravaginal electrical stimulation (IVS), 24 women with pure stress incontinence, mixed urge and stress incontinence or urge incontinence due to detrusor instability, were treated. To minimize mechanical discomfort, the electrode carrier was made of flexible material and inflatable. Furthermore, this design facilitated fixed,(More)
We treated 14 women with chronic interstitial cystitis with long-term intravaginal or transcutaneous nerve stimulation. Clinical and urodynamic evaluations were done after 6 months to 2 years. Improvement was not immediate but required a considerable period of continuous, daily use of electrical stimulation. The results were favorable--a substantial(More)
The clinical efficacy of a new device for treatment of female incontinence was studied in a multicenter trial. The device consists of an inflatable electrode carrier and an external stimulator unit. Forty women were treated: 10 had primary or recurrent genuine stress incontinence, 15 had urge incontinence due to idiopathic detrusor instability, not(More)
The effect on the urethra of intravaginal electrical stimulation (IVS) was registered by means of urethral pressure profiles (UPP). With the object of finding the most appropriate electrical parameters and optimal electrode positions within the vagina, 24 patients with stress incontinence, 22 with urgency and 4 continent women were studied. Electrical(More)
In 1977, a new phase began in hearing rehabilitation of patients with chronic middle and external diseases and atresias. Thus far, these patients have had to rely on conventional bone conduction and air conduction devices that for various reasons give poor rehabilitation. The principle of the new treatment, made possible by the Swedish bone-anchored hearing(More)
This paper describes a prototype system that uses an advanced data acquisition processor in combination with a personal computer (PC) to analyse surface electromyogram (EMG) signals on-line and in real-time. The system is able to calculate the average power and estimate the mean frequency of the power spectrum of surface EMGs during static and repeated(More)
Clinical observations have indicated that not only stress incontinence due to defective urethral closure but also urge incontinence due to bladder hyperactivity can be successfully treated by electrical stimulation of the pelvic floor. Clinical investigations revealed that intravaginal electrical stimulation caused bladder inhibition registered as a volume(More)
