The Impact of Extracorporeal Magnetic Stimulation as Addition to Mirabegron in Overactive Bladder Treatment in Women: A Single-Centre Randomized Sham-Controlled Study. J Clin Med 2024; 13:916. [PMID: 38337609 PMCID: PMC10856599 DOI: 10.3390/jcm13030916] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/14/2024] [Revised: 01/30/2024] [Accepted: 02/03/2024] [Indexed: 02/12/2024] Open
Abstract
(1) Background: The purpose of our prospective, single-blinded, randomized, sham-controlled study was to investigate the effect of the additional extracorporeal magnetic stimulation (ExMI) to pharmacological treatment in overactive bladder syndrome (OAB) in women. (2) Methods: We recruited 56 women with OAB, who were allocated into two study groups: the active group received mirabegron 50 mg daily and a total of 16 sessions of ExMI in 8 weeks, whereas the sham group received mirabegron 50 mg daily and sham stimulation following the same treatment protocol. Treatment success was evaluated after 4 and 8 weeks. (3) Results: Both groups experienced significant reduction in daytime urinary frequency, nocturia, and number of weekly incontinence episodes after 8 weeks. There were no statistically significant differences in end-point daytime urinary frequency and nocturia between groups. However, the overall average reduction rate in weekly number of incontinence episodes was 43.7% in treatment group and 24.2% in the control group. The number of urinary incontinence episodes in the treatment and control group was reduced for 3.8 ± 11.8 vs. 2.5 ± 4.3 episodes at week 4 and additional 3.3 ± 6 vs. 0.4 ± 3.2 episodes at week 8, respectively (p = 0.013). Moreover, IIQ-7 score showed a significantly greater score reduction and patients' evaluated improvement of symptoms was higher in the active group. (4) Conclusions: The addition of ExMI to mirabegron in OAB treatment further improves the weekly incontinence episode reduction rate and also leads to grater improvement in symptoms.

Abstract
Background and Objectives: Magnetic stimulation is a type of conservative treatment of urinary incontinence. Our aim was to evaluate the possible side effects of this method. Materials and Methods: We conducted a systematic literature review. The key search terms were urinary incontinence, magnetic stimulation, and female. All known synonyms were used. Results: 255 titles and abstracts were retrieved, and 28 articles met our inclusion criteria. Out of 28 studies, 15 reported no side effects, five reported side effects, and eight did not report anything. There was no significant difference in the incidence of side effects between the sham and active treatment groups. Conclusions: Side effects of magnetic stimulation in comparison to other active treatments are minimal and transient. Among the conservative UI treatment methods, magnetic stimulation is one of the safest methods for the patient and as such a suitable first step in treating UI.

Impact of ao-dake-humi, Japanese traditional bamboo foot stimulator, on lower urinary tract symptoms, constipation and hypersensitivity to cold: a single-arm prospective pilot study. Altern Ther Health Med 2016; 16:513. [PMID: 27938362 PMCID: PMC5148827 DOI: 10.1186/s12906-016-1494-1] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.1] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/12/2015] [Accepted: 11/24/2016] [Indexed: 12/16/2022]
Abstract
Background Ao-dake-humi is a traditional Japanese bamboo foot stimulator consisting of a half-pipe-shaped step made of bamboo used to stimulate the foot by stepping on it, and is commonly used to promote general health among the elderly in Japan. However, its efficacy has not been reported in the scientific literature. This study was performed to investigate the role of ao-dake-humi focusing on lower urinary tract symptoms (LUTS), constipation, and hypersensitivity to cold (HC). Methods Participants with LUTS, constipation, or HC were enrolled in this study. Ao-dake-humi was used twice a day for 28 days. Before and 28 days after starting ao-dake-humi use, international prostate symptom score (IPSS), quality-of-life (QoL) score, and overactive bladder symptom score (OABSS) were measured to evaluate the efficacy of ao-dake-humi on LUTS. To evaluate the objective efficacy of ao-dake-humi on LUTS, a frequency-volume chart (FVC) was plotted in LUTS patients for 3 days. A visual analogue scale (VAS) was used to evaluate the efficacy of ao-dake-humi on constipation (VAS-constipation) and HC (VAS-HC) in the participants with constipation or HC. Results A total of 24 participants were enrolled in this study. Twenty-one participants had LUTS, 11 had constipation, and 17 participants had HC. IPSS, especially storage-subscore, QoL score and OABSS, decreased significantly after use of ao-dake-humi. The use of ao-dake-humi increased maximal bladder capacity, resulting in a significant decrease in urinary frequency as determined from the FVC. In accordance with the results of VAS-constipation and VAS-HC, both constipation and HC were significantly relieved after ao-dake-humi use. Conclusion The results of this prospective pilot study indicated that ao-dake-humi is safe and has therapeutic efficacy in cases of LUTS, constipation and HC. The possibility of using ao-dake-humi as physical neuromodulation therapy was shown in the management of LUTS, constipation and HC. Trial registration UMIN000019333 (UMIN-CTR, Registered October-15-2015) retrospectively registered.

Abstract
Neuromodulation has been reported to be effective for the treatment of stress and urgency urinary incontinence. The cure and improvement rates of pelvic floor neuromodulation in urinary incontinence are 30-50% and 60-90%, respectively. In clinical practice, vaginal, anal and surface electrodes are used for external, short-term stimulation, and sacral nerve stimulation for internal, chronic (long-term) stimulation. The effectiveness of neuromodulation has been verified in a randomized, placebo-controlled study. However, the superiority to other conservative treatments, such as pelvic floor muscle training has not been confirmed. A long-term effect has also been reported. In conclusion, pelvic floor exercise with adjunctive neuromodulation is the mainstay of conservative management for the treatment of stress incontinence. For urgency and mixed stress plus urgency incontinence, neuromodulation may therefore be the treatment of choice as an alternative to drug therapy.

Abstract
OBJECTIVES To observe the effect of both acute and medium-term magnetic stimulation of the pelvic floor on detrusor function amongst women with idiopathic detrusor overactivity (IDO). METHODS Two separate studies were undertaken amongst women with a sole diagnosis of IDO. The first study assessed the acute effect of magnetic stimulation (provided by Neocontrol ) on detrusor function during the filling phase of standard cystometry. Multiple filling cycles were performed with stimulation at a different key moment in each. This was done to establish that the device could influence the detrusor. Subsequently, a randomized sham control trial was performed to assess clinical efficacy. A total of 20 treatments, each of 20 minutes duration, were administered over six weeks with follow-up six weeks thereafter. Half the patients received therapy from a genuine device, the others receiving fake treatment on an identical looking/sounding sham device. The sham device contained a deflector plate to degrade the magnetic field and was located in a separate room. Outcome measures included changes in a 24 hour fluid volume chart, urine loss (24 hour pad test) and quality of life instruments. RESULTS Amongst 10 patients receiving stimulation during cystometry, volume at first involuntary detrusor contraction during filling rose from a median value of 240ml (Inter-quartile range (IQR) 210-300) to 285ml (IQR 231-320), p = 0.03 and maximum detrusor pressure decreased from 40cm water (IQR 34-45) to 33cm water (IQR 25-41), p<0.01. The RCT was completed by 29 of 44 (66%) recruits. Of these, 15 of 29 (52%) received active treatment and 14 of 29 (48%) sham therapy. Active therapy significantly reduced the number of urge episodes per day, p<0.01. With respect to baseline, actively treated patients experienced significant reduction in voids per day and quality of life but this trend did not reach significance when compared to the sham group, partly due to unexpected difficulty in recruitment which yielded an underpowered sample size for these outcome measures. CONCLUSIONS Magnetic stimulation reduces detrusor contractility in the acute phase of administration. Although the treatment was well tolerated and urge episodes reduced following prolonged therapy, no statistically significant improvement was observed in quality of life indices or measured 24 hour urinary loss. The treatment cannot be recommended for women with IDO.

Abstract
This review article discusses the efficacy of various conservative therapies in the management of voiding dysfunction with special reference to urinary incontinence. The article emphasizes the fact that conservative therapies have limited side effects and they do not jeopardize future treatment options. Behaviour therapy, pelvic floor therapy and biofeedback; electrical and magnetic stimulation are discussed here individually. Though there is unanimous agreement that these therapies improve quality of life, complete cure is rare. All therapies work better in conjunction with each other rather than in isolation. The review also highlights the need for randomized controlled trials of better methodology.

Abstract
The purpose of this study was to prospectively evaluate symptom change after discontinuation of extracorporeal magnetic stimulation (EMS) in women with overactive bladder (OAB). A total of 48 women with OAB were included. We applied 10 Hz of repetitive magnetic stimulation with a "magnetic chair" for 20 min, twice weekly for 8 weeks. Changes in OAB symptoms at 2, 12, and 24 weeks after discontinuing the EMS were evaluated. Twenty-seven (56.3%) patients were cured compared with the baseline at 2 weeks: the cure rate was determined as 68.8% (33/48 patients), 56.3% (27/48), and 50% (8/16) for urgency, frequency, and urge incontinence, respectively. The mean number of voids per 24 h was decreased by 42.8% (from 14.5 +/- 4.3, to 8.3 +/- 1.5, P < 0.001) at 2 weeks after treatment. Maximum voided volume did not change significantly, but the mean voided volume increased significantly after stimulation. Twenty-six (96.3%) patients among the 27 patients who achieved a cure at 2 weeks, maintained improvement at 24 weeks; the therapeutic effect on urgency, frequency, and urge incontinence persisted in 26 (78.8%) of 33 patients, 26 (96.3%) of 27 patients, and six (75%) of eight patients, respectively. There were no significant changes in urodynamic parameters. Of the 14 patients with detrusor overactivity, the condition was no longer observed in four (28.6%) patients. EMS has a beneficial effect on women with OAB. Our data suggest EMS may have a significant carry-over effect in well-selected OAB patients.

Abstract
PURPOSE OF REVIEW This review looks at the acute effects of magnetic stimulation on urodynamic parameters and reviews the data on its use in the management of urinary incontinence. RECENT FINDINGS Reported cure rates for stress incontinence immediately after a course of perineal magnetic stimulation range from 12.5 to 52.9% with good improvement occurring in 32% to 41%. However the effect seems temporary and dependent on the number of sessions. Sacral and pelvic floor magnetic stimulation have also been shown to increase cystometric capacity, inhibit detrusor overactivity and resolve overactive bladder symptoms acutely. Persistence of this effect with symptomatic improvement one week after sacral magnetic stimulation has been demonstrated. How magnetic stimulation suppresses detrusor contraction is not known. Prospective trials with the Neocontrol chair (Neotonus Inc, Marietta, Georgia, USA) also showed symptomatic improvement in 71 to 87% in the short term. However, the longer term data appear mixed. SUMMARY Overall, the data available vary too much in terms of treatment protocols, patient mix and symptom severity to determine which group of patients might benefit most and what the optimal stimulation parameters are for each condition. Mean reductions in leak parameters, although statistically significant, may not always be clinically satisfactory. The beneficial effects also appear to be temporary and continuous treatment will probably be required. Further trials are needed to determine the optimum stimulation protocols for different situations and to compare magnetic stimulation with other forms of conservative pelvic floor therapy.

Abstract
OBJECTIVE To determine the effect of extracorporeal pelvic floor magnetic stimulation in children with an overactive bladder, as although such stimulation is an effective treatment for voiding dysfunction such as urge incontinence (UI) and urgency-frequency syndrome, experience in children is scarce. PATIENTS AND METHODS This prospective study included 42 children diagnosed with an overactive bladder, based on urodynamic or video-urodynamic study; a complete follow-up was available in 34. The children were grouped into those with UI only, not monosymptomatic nocturnal enuresis (nMNE), or MNE, according to their symptoms. Clinical variables were assessed by recording a voiding and nocturnal enuresis diary before and after magnetic stimulation, the latter being administered twice a week for 4 weeks using a size-adjusted magnetic chair (each session took 20 min). RESULTS The UI only and nMNE group had a significant decrease in voiding frequency and frequency of UI (P < 0.05); the MNE group also had a significant decrease in voiding frequency (P < 0.05). There was a significant increase in functional bladder capacity in all groups (P < 0.05) but no significant decrease in the mean volume and frequency of NE in the nMNE and MNE groups (P > 0.05). CONCLUSIONS Extracorporeal pelvic floor magnetic stimulation has an acute effect on voiding dysfunction such as urge syndrome in children. However, controlled studies with a sham-stimulation group and various durations of stimulation are necessary for its application as a primary treatment for voiding dysfunction in children.
