[PMID: 32419791 PMCID: PMC7201846 DOI: 10.1155/2020/1705964] [Citation(s) in RCA: 7] [Impact Index Per Article: 1.8] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 01/21/2020] [Revised: 03/12/2020] [Accepted: 03/28/2020] [Indexed: 11/18/2022]
Abstract
OBJECTIVE The aim of this study was to investigate the clinical efficacy of laser acupuncture for the treatment of women with overactive bladder (OAB) in Taiwan. METHODS A double-blind randomized controlled trial was conducted on female patients with OAB symptoms referred from gynecologists, and subjects were divided into two groups using blocked randomization. LaserPan (RJ-Laser, Germany) was applied to seven selected acupuncture points. The subjects received laser acupuncture 3 times per week for 3 weeks, 9 sessions in total. Basic patient data, Overactive Bladder Symptom Score (OABSS), Incontinence Impact Questionnaire (IIQ-7), and Urogenital Distress Inventory (UDI-6) scores were recorded prior to first treatment and at the end of 3rd, 6th, and 9th treatments. RESULTS Thirty patients were enrolled, and twenty-seven patients completed all treatments in this study. The OABSS total score of the experimental group decreased significantly by 3.13 (p ≤ 0.001), 4.60 (p ≤ 0.001), and 3.79 (p ≤ 0.001) after 3rd, 6th, and 9th treatments, respectively, compared with that of the control group. The IIQ-7 score declined significantly from baseline by 4.57 (p=0.003) and 3.63 (p=0.023) after 3rd and 6th treatments, respectively, compared with that of the control group. Similarly, the UDI-6 score of the experimental group exhibited a significant decrease from baseline by 1.90 (p=0.042) and 2.25 (p=0.025) after 6th and 9th interventions, respectively, compared with that of the control group. CONCLUSIONS This study demonstrates that laser acupuncture can alleviate OAB symptoms and improve quality of life. This noninvasive device could be an effective therapy for women with OAB.

Abstract
One of the major causes of nocturia is overactive bladder (OAB). Somatic afferent nerve stimuli are used for treating OAB. However, clinical evidence for the efficacy of this treatment is insufficient due to the lack of appropriate control stimuli. Studies on anesthetized animals, which eliminate emotional factors and placebo effects, have demonstrated an influence of somatic stimuli on urinary bladder functions and elucidated the underlying mechanisms. In general, the effects of somatic stimuli are dependent on the modality, location, and physical characteristics of the stimulus. Recently we showed that gentle stimuli applied to the perineal skin using a soft elastomer roller inhibited micturition contractions to a greater extent than a roller with a hard surface. Studies aiming to elucidate the neural mechanisms of gentle stimulation-induced inhibition reported that 1-10 Hz discharges of low-threshold cutaneous mechanoreceptive Aβ, Aδ, and C fibers evoked during stimulation with an elastomer roller inhibited the micturition reflex by activating the spinal cord opioid system, thereby reducing both ascending and descending transmission between bladder and pontine micturition center. The present review will provide a brief summary of (1) the effect of somatic electrical stimulation on the micturition reflex, (2) the effect of gentle mechanical skin stimulation on the micturition reflex, (3) the afferent, efferent, and central mechanisms underlying the effects of gentle stimulation, and (4) a translational clinical study demonstrating the efficacy of gentle skin stimuli for treating nocturia in the elderly with OAB by using the two roller types inducing distinct effects on rat micturition contractions.

Abstract
The brainstem is essential for producing micturition contractions of the urinary bladder. Afferent input from perineal skin evoked by gentle mechanical stimulation inhibits micturition contractions by decreasing both ascending and descending transmissions between the brainstem and spinal cord. Dysfunction of this inhibitory mechanism may be one cause of the increase in the prevalence of overactive bladder in old age. The aim of this study was to examine effect of aging on function of skin afferent fibers that inhibit bladder micturition contractions in rats. We used anesthetized male rats in three different age groups: young adult (4–5 months old), middle aged (6–9 months old), and aged (27–30 months old). The bladder was expanded to produce isovolumetric rhythmic micturition contractions. Skin afferent fibers were activated for 1 min either by electrical stimulation (0.5 ms, 0.2–10 V, 0.1–10 Hz) of the cutaneous branch of the pudendal nerve (CBPN) or by gentle mechanical skin stimulation with an elastomer roller. When skin afferent nerves were activated electrically, micturition contractions were inhibited in a similar manner in all age groups, with long latency inhibition induced by excitation of Aβ fibers and short latency inhibition by additional Aδ and C fiber excitation (at 1–10 Hz). On the contrary, when skin afferent nerves were activated mechanically by rolling, latency of inhibition following rolling stimulation was prolonged in aged rats. Single unitary afferent nerve activity of low-threshold mechanoreceptors (LTMs) from the cutaneous nerve was recorded. The discharge rate during rolling was not significantly reduced in Aβ units but was much lower in Aδ and C units in aged rats (0.4 and 0.5 Hz, respectively) than in young adult rats (3 and 7 Hz). These results suggest that the neural mechanism that inhibits bladder micturition contractions by skin afferent input is well maintained in old age, but the early inhibition by gentle skin stimulation is decreased because of reduced responses of Aδ- and C-LTMs.

Abstract
Objective: The use of noninvasive skin stimulation with microcones for constipation is promising. However, no double-blinded study has assessed the effects of this approach on constipation. The goal of this research was to assess the effects on constipation when using noninvasive skin stimulation with microcones. Materials and Methods: This double-blinded, controlled study included 44 subjects, each with a score of 5 points or higher on the Japanese version of the Constipation Assessment Scale (CAS-J). The subjects were randomly divided into 2 groups: (1) a stimulation group (skin-stimulation device with microcones; n = 23; group S) and (2) a placebo group (identical device without microcones; n = 21; group P). The subjects were required to attach the skin-stimulation devices to both cavum conchae with dedicated bandages every day for 2 months by themselves. Main Outcome Measures: This study assessed the severity of constipation, total mood disturbance (TMD) score, and salivary amylase activity (SAA) in each subject. Measurements were obtained before, during, and after the intervention. Results: With regard to the CAS-J score, significant differences were observed in both groups; however, no significant differences were observed between the groups. With regard to the TMD score, significant differences were observed in group S but not in group P. With regard to SAA, there were no significant differences in both groups; however, significant differences were noted after the intervention between the groups. Conclusions: Noninvasive skin stimulation with microcones could relieve constipation and improve TMD scores and SAA activity. This procedure may be used as a self-care option.

Somatoautonomic reflexes in acupuncture therapy: A review. Auton Neurosci 2016; 203:1-8.

Abstract
Oriental therapies such as acupuncture, moxibustion, or Anma, have been used to treat visceral disorders since ancient times. In each of these therapies, stimulation of the skin or underlying muscles leads to excitation of afferent nerves. The sensory information is carried to the central nervous system, where it is transferred to autonomic efferents, thus affecting visceral functions. This neuronal pathway, known as the "somatoautonomic reflex", has been systematically studied by Sato and his colleagues for over a half century. Nearly all their studies were conducted in anesthetized animals, whereas human patients are conscious. Responses in patients or the events following therapeutic somatic stimulation may differ from those observed in anesthetized animals. In fact, it is increasingly apparent that the responses in patients and animals are not always coincident, and the differences have been difficult for clinicians to reconcile. We review the mechanism of the "somatoautonomic reflex" as described in anesthetized animals and then discuss how it can be applied clinically.

Stimulus frequency-dependent inhibition of micturition contractions of the urinary bladder by electrical stimulation of afferent Aβ, Aδ, and C fibers in cutaneous branches of the pudendal nerve. J Physiol Sci 2016; 66:491-496. [PMID: 27384685 PMCID: PMC5045840 DOI: 10.1007/s12576-016-0468-x] [Citation(s) in RCA: 6] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/02/2016] [Accepted: 06/20/2016] [Indexed: 02/02/2023]
Abstract
We aimed to examine the afferent mechanisms for the reflex inhibition of the rhythmic micturition contractions (RMCs) of the urinary bladder induced by stimulation of the perineal skin afferents in urethane-anesthetized rats. Electrical stimulation (pulse duration: 0.5 ms) was applied to the cutaneous branches of the pudendal nerve (CBPN) at frequencies of 0.1, 1, and 10 Hz for 1 min. Nerve fiber groups were defined by recording compound action potentials from CBPN. Activation of only Aβ fibers (0.2 V) produced an inhibition of RMCs at 7-11 min after the onset of stimulation (late inhibition), at any tested frequency. Additional activation of Aδ fibers (1 V) produced additional early inhibition (immediately after stimulation) at 1 and 10 Hz. Furthermore, additional activation of C fibers (10 V) at 10 Hz completely stopped RMCs for >10 min. This strong inhibition persisted after local application of capsaicin to the stimulating CBPN. We conclude that activities of Aβ, Aδ, and C afferent fibers, without capsaicin-sensitive channels, can contribute to the inhibition of bladder contractions.
