The effectiveness of magnetic stimulation for patients with pelvic floor dysfunction: A systematic review and meta-analysis

Effects of nonsurgical, minimally or noninvasive therapies for urinary incontinence due to neurogenic bladder: a systematic review and meta-analysis

Objective:

To determine the effects of nonsurgical, minimally or noninvasive therapies on urge urinary incontinence (UUI) symptoms and quality of life (QoL) in individuals with neurogenic bladder (NGB).

Data Sources:

Cochrane library, EMBASE, MEDLINE, PEDro, Scopus, and Web of Science databases were searched from inception to September 2021.

Review Methods:

Randomized controlled trials that compared therapies such as intravaginal electrical stimulation (IVES), transcutaneous electrical nerve stimulation (TENS), neuromuscular electrical stimulation (NMES), transcutaneous tibial nerve stimulation (TTNS), pelvic floor muscle training (PFMT), and behavioural therapy (BT) to control were included. Study screening, data extraction, and study quality assessments were performed by two independent authors.

Results:

Fourteen trials with 804 participants were included in the study after screening of 4281 potentially relevant articles. Meta-analyses revealed a significant effect of electrical stimulation on UUI due to multiple sclerosis (standardized mean difference (SMD): −0.614; 95% confidence interval (CI): −1.023, −0.206; p = 0.003) and stroke (SMD: −2.639; 95% CI: −3.804, −1.474; p = 0.000). The pooled analyses of TTNS (weighted mean difference (WMD): −12.406; 95% CI: −16.015, −8.797; p = 0.000) and BT (WMD: −9.117; 95% CI: −14.746, −3.487; p = 0.002) revealed significant effects of these interventions on QoL in people with Parkinson’s disease. However, meta-analyses revealed nonsignificant effects for PFMT (WMD: −0.751; 95% CI: −2.426, 0.924; p = 0.380) and BT (WMD: −0.597; 95% CI: −1.278, 0.083; p = 0.085) on UUI due to Parkinson’s disease.

Conclusions:

Our meta-analyses found electrical stimulation to be beneficial for improving the symptoms of UUI among people with multiple sclerosis and those with stroke. Our review also revealed that TTNS and BT might improve QoL for people with NGB due to Parkinson’s disease, although the effects of PFMT and BT on UUI warrant further investigation.

A Randomized Controlled Trial of Repetitive Peripheral Magnetic Stimulation applied in Early Subacute Stroke: Effects on Severe Upper-limb Impairment

OBJECTIVES

Repetitive peripheral magnetic stimulation (rPMS) is a non-invasive method that activates peripheral nerves and enhances muscle strength. This study aimed to investigate the effect of rPMS applied in early subacute stroke on severe upper extremity impairment.

DESIGN

Randomized controlled trial.

SETTING

Rehabilitation department of a university hospital.

SUBJECTS

People aged 30-80 years with no practical arm function within four weeks of a first stroke.

INTERVENTIONS

Participants were randomly assigned to either the rPMS group (n = 24, 20Hz and 2400 pulses of rPMS to triceps brachii and extensor digitorum muscles daily for two weeks in addition to conventional physiotherapy) or the control group (n = 20, conventional physiotherapy).

MAIN MEASURES

The primary outcome was the upper extremity motor section of Fugl-Meyer Assessment after treatment. Secondary outcomes included Barthel Index and root mean square of surface electromyography for muscle strength and stretch-induced spasticity of critical muscles of the upper extremity. Data presented: mean (SD) or median (IQR).

RESULTS

The rPMS group showed more significant improvements in the Fugl-Meyer Assessment (12.5 (2.5) vs. 7.0 (1.4), P < 0.001), Barthel Index (15 (5) vs. 10 (3.7), P < 0.001), and strength-root mean square (biceps brachii: 20.5 (4.8) vs. 6.2 (2.7), p < 0.001; triceps brachii: 14.9 (5.8) vs. 4.3 (1.2), p < 0.001; flexor digitorum: 5.1 (0.8) vs. 4.0 (1.1), p < 0.001) compared with the control group.

CONCLUSION

In patients with no functional arm movement, rPMS of upper limb extensors improves arm function and muscle strength for grip and elbow flexion and extension.

Effects of extracorporeal magnetic stimulation on urinary incontinence: A systematic review and meta-analysis

AIMS

To examine the effectiveness of extracorporeal magnetic stimulation for treatment of stress urinary incontinence.

DESIGN

Systematic review and meta-analysis.

DATA RESOURCES

Four electronic databases from inception to 18 May 2019.

REVIEW METHODS

Two authors independently performed the search, assessed the methodological quality, and extracted data. The final studies included in the analysis were selected after reaching consensus with the third author.

RESULTS

A total of 20 studies were included in the systematic review and 12 of these in the meta-analysis. Quality assessment indicated that only 8 of 17 randomized controlled trials had low risk in overall risk of bias, whereas all controlled trials had serious risk of bias. The weighted mean effect size of magnetic stimulation on quality of life, number of leakages, pad test outcomes, and number of incontinence events was 1.045 (95% CI: 0.409-1.681), -0.411 (95% CI: 0.178-0.643), -0.290 (95% CI: 0.025-0.556), and -0.747 (95% CI: -1.122 to -0.372), respectively. Subgroup analysis revealed a significant difference in the type of quality of life measurement used. Sensitivity analyses revealed that a high degree of heterogeneity persisted even after omitting studies individually.

CONCLUSIONS

Extracorporeal magnetic stimulation may be effective in treating urinary incontinence and improving quality of life without major safety concerns. However, because of a high degree of heterogeneity among studies, inferences from the results must be made with caution.

IMPACT

We recommend that clinical nurses apply extracorporeal magnetic stimulation to treat stress urinary incontinence among female patients and encourage researchers to conduct further qualitative and quantitative studies to develop consistent content and dosage for the intervention.

STUDY REGISTRATION

The review protocol was registered a priori and published online in the PROSPERO database of systematic reviews (www.crd.york.ac.uk/Prospero with the registration number #CRD42019138835).

Urinary Incontinence in Women: Modern Methods of Physiotherapy as a Support for Surgical Treatment or Independent Therapy

Urinary incontinence (UI) is a common health problem affecting quality of life of nearly 420 million people, both women and men. Pelvic floor muscle (PFM) training and other physiotherapy techniques play an important role in non-surgical UI treatment, but their therapeutic effectiveness is limited to slight or moderate severity of UI. Higher UI severity requires surgical procedures with pre- and post-operative physiotherapy. Given that nearly 30%–40% of women without dysfunction and about 70% with pelvic floor dysfunction are unable to perform a correct PFM contraction, therefore, it is particularly important to implement physiotherapeutic techniques aimed at early activation of PFM. Presently, UI physiotherapy focuses primarily on PFM therapy and its proper cooperation with synergistic muscles, the respiratory diaphragm, and correction of improper everyday habits for better pelvic organ support and continence. The purpose of this work is a systematic review showing the possibilities of using physiotherapeutic techniques in the treatment of UI in women with attention to the techniques of PFM activation. Evidence of the effectiveness of well-known (e.g., PFM training, biofeedback, and electrostimulation) and less-known (e.g., magnetostimulation, vibration training) techniques will be presented here regarding the treatment of symptoms of urinary incontinence in women.

Traditional Biofeedback vs. Pelvic Floor Physical Therapy-Is One Clearly Superior?

PURPOSE OF REVIEW

Pelvic floor physical therapy is a worldwide accepted therapy that has been exclusively used to manage many pelvic floor disorders in adults and children. The aim of this review is to suggest to clinicians an updated understanding of this therapeutic approach in management of children with non-neuropathic voiding dysfunction.

RECENT FINDINGS

Today, pelvic floor muscle training through biofeedback is widely used as a part of a voiding retraining program aiming to help children with voiding dysfunction which is caused by pelvic floor overactivity. Biofeedback on its own, without a pelvic floor training component, is not an effective treatment. Biofeedback is an adjunct to the pelvic floor training. In the current review, we develop the role of pelvic floor physical therapy in management of children with non-neuropathic voiding dysfunction and compare it with biofeedback therapy alone.
