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

Innovative use of physical therapy for pediatric bowel and bladder dysfunction: Not just biofeedback!

Biofeedback has been shown to be an effective tool in the treatment of pelvic floor dysfunction in patients with bowel and bladder dysfunction, and commonly, biofeedback is provided within a physical therapy plan of care. In building a pelvic floor physical therapy program at our institution, we have found that physical therapy extends beyond biofeedback. Our preliminary experience demonstrates that patients experience more rapid symptomatic improvement when biofeedback is combined with additional therapy to address abnormal core and respiratory function.

Basic vs electromyographic biofeedback-assisted pelvic floor muscle training for the improvement of sexual function after total hysterectomy: a prospective study

Background

Pelvic floor muscle training (PFMT) has emerged as a potential intervention to improve post-total hysterectomy (TH) sexual function. Electromyographic (EMG) biofeedback is an adjunct that may improve outcomes.

Aim

In this study we aimed to compare the EMG biofeedback-assisted PFMT and PFMT alone for improving sexual function in women after TH.

Methods

For this prospective study we enrolled women undergoing TH in our hospital between January 2022 and April 2023. Participants were divided according to the treatment they selected: EMG biofeedback-assisted PFMT or PFMT alone.

Outcomes

The primary study outcome was change in patient sexual function evaluated by use of the Female Sexual Function Index. Secondary outcomes were changes in anxiety and depression evaluated with the Hospital Anxiety and Depression Scale score and pelvic floor muscle strength was evaluated with the Glazer assessment performed from before to after treatment.

Results

A total of 73 patients were included, with 38 patients treated with Electromyographic biofeedback-assisted pelvic floor muscle training. After treatment, sexual function was significantly improved compared to baseline in all patients (all P < .001). Compared to patients with pelvic floor muscle training, the changes in total Female Sexual Function Index scores from before to after treatment in patients with Electromyographic biofeedback-assisted pelvic floor muscle training were significantly higher (all P < .05). There were no significant differences between the 2 groups in the changes in the Glazer score and Hospital Anxiety and Depression Scale scores from before to after treatment (both P > .05).

Clinical Translation

The results demonstrate that Electromyographic biofeedback-assisted pelvic floor muscle training may be used to improve the sexual function of patients following TH.

Strengths and Limitations

This study is limited by its single-center design, small sample size, lack of randomization, and absence of estrogen monitoring in enrolled participants.

Conclusions

Electromyographic biofeedback-assisted pelvic floor muscle training appears to be more effective than pelvic floor muscle training alone in improving sexual function among patients after total hysterectomy.

Pelvic floor physical therapy and mindfulness: approaches for chronic pelvic pain in women-a systematic review and meta-analysis

PURPOSE

Chronic pelvic pain (CPP) in women is a complex syndrome and symptoms are associated with sexual dysfunction, musculoskeletal and myofascial disorders, and comorbid psychiatric disorders. Its widespread prevalence results in substantial expense due to therapy and lost productivity, and it is perhaps one of the most urgent and neglected medical needs. This systematic review and meta-analysis aimed to estimate the role of mindfulness and pelvic floor physical therapy (PFPT) in the treatment or management of women with CPP.

METHODS

This systematic review (CRD42020204987) searched for relevant publications between January 2000 and November 2020 on MEDLINE/PubMed, Web of Science, One File GALE, and Technology Research databases using the following search terms: chronic pelvic pain, pelvic floor physical therapy/physiotherapy, mindfulness, and their variants. Risk of bias and quality of evidence were evaluated.

RESULTS

Seven clinical trials (n = 279) were included in the review, and five in the meta-analysis (n = 225). For the pain outcome and its catastrophizing, there was a statistical difference for the Pain Catastrophizing Scale after treatment and during follow-up with mindfulness and PFPT (MD = - 3.82 [- 6.97, - 0.68], p = 0.01, and MD = - 4.49 [- 7.61, - 1.37], p = 0.00, respectively). Sexual function, assessed by the female sexual function index, differed significantly during follow-up between PFPT and mindfulness (MD = - 0.72 [- 1.38, - 0.05], p = 0.03).

CONCLUSION

The small number of studies applying both PFPT and mindfulness to CPP suggests that a multidisciplinary approach is required to treat women with CPP, and further studies involving these therapeutic techniques throughout the CPP cycle are needed.

The effect of pelvic floor muscle training in women with functional bladder outlet obstruction

INTRODUCTION AND HYPOTHESIS

Female voiding dysfunction is often due to bladder outlet obstruction (BOO). We investigated pelvic floor muscle training (PFMT) effectiveness in women with functional BOO.

METHODS

This is a prospective study recruiting 63 women functionally obstructed, over 18yo, maximum flow rate (Qmax) less than 12 ml/sec, naïve of voiding treatment. Exclusion criteria were anatomical BOO, neurological condition, pelvic intervention, psychiatric or anticholinergic medication, diabetes mellitus and affected upper urinary tract. At baseline, women underwent uroflow, post void residual (PVR) measurement, cystoscopy, cystogram and urodynamic study (UDS) with pelvic electromyography (EMG). Blaivas-Groutz nomogram has been used to define obstruction. After diagnosis, patients underwent six-month PFMT. Re-evaluation was offered four weeks after end of treatment. Data were analyzed with SPSSv22.0.

RESULTS

63 women were recruited and 48 finally included. At baseline, 20 reported 3 urinary tract infections (UTIs) during last year, and 12 had one episode of urine retention. Median Qmax was 7.5 ml/sec and median PVR 110 ml. 40 women were obstructed. 16 (40%) had mild, 16 (40%) moderate and 8 (20%) severe obstruction. All subjects had an overactive pelvic floor on EMG. Obstructed women were re-evaluated. Median Qmax was 8.5 ml/sec, close to baseline (p = 0.16). Median PVR was 65 ml, reduced to baseline (p = 0.02). 33 (82.5%) remained obstructed, 22 (66.67%) with mild, 8 (24.24%) moderate and 3 (9.09%) severe obstruction. 7 (17.5%) were non-obstructed. 4 patients reported one UTI episode with no cases of retention.

CONCLUSIONS

A 6 month PFMT reduced UTIs and PVR in women with functional BOO. Additionally, most patients had a de-escalation to milder obstruction.

Is biofeedback-assisted pelvic floor muscle training superior to pelvic floor muscle training alone in the treatment of dysfunctional voiding in women? A prospective randomized study

Purpose:

To compare the effectiveness of biofeedback-assisted pelvic floor muscle training (PFMT) and PFMT alone on voiding parameters in women with dysfunctional voiding (DV).

Materials and Methods:

The patients in group 1 (34 patients) were treated with biofeedback-assisted PFMT, and the patients in group 2 (34 patients) were treated with PFMT alone for 12 weeks. The 24-hour frequency, average voided volume, maximum urine flow rate (Q_max), average urine flow rate (Q_ave), post-void residual urine volume (PVR), and the validated Turkish Urogenital Distress Inventory (UDI-6) symptom scores were recorded before and after 12 weeks of treatment.

Results:

At the end of treatment sessions, the Q_max and Q_ave values of the patients in group 1 were significantly higher than those in group 2, and the PVR in the patients in group 1 was significantly lower than those in group 2 (p=.026, .043, and .023, respectively). The average UDI-6 symptom scores of the patients in group 1 were significantly lower than those in group 2 (p=.034). Electromyography activity during voiding, in group 1 was significantly lower than in group 2 (41.2 vs. 64.7, respectively, p=.009).

Conclusion:

Biofeedback-assisted PFMT is more effective than PFMT alone in improving clinical symptoms, uroflowmetry parameters, and EMG activity during voiding.

The efficacy of physiotherapeutic intervention with biofeedback assisted pelvic floor muscle training in children with dysfunctional voiding

INTRODUCTION

Dysfunctional voiding (DV) in children is a common issue, which can be found in up to 30% of children with wetting problems. Biofeedback assisted pelvic floor muscle training (PFMT) is an established nonpharmacological method to treat DV. The aim of the present study was to evaluate the efficacy of physiotherapeutic intervention with biofeedback assisted PFMT in children with DV.

STUDY DESIGN

Children referred with DV, unresponsive to standard urotherapy were included in this study. All children underwent biofeedback assisted PFMT sessions with a physiotherapist. Uroflowmetries and measurements of post-void residual (PVR) urine were performed before and after the treatment, and the following parameters were registered; daytime incontinence (DI), nocturnal enuresis (NE), constipation, faecal incontinence (FI), and recurrent urinary tract infections (UTI). Other concomitant treatments were noted. The primary outcomes were the resolution of DV evaluated by uroflow curve configuration and PVR. Secondary outcomes were the resolution of DI, NE and the reduction of recurrent UTIs.

RESULTS

Forty-six children (mean age 9.6 ± 2.4 years, 38 girls) were included in the analysis. The median period of treatment was 9.0 ± 8.5 months (2-9 visits). Twenty-seven (59%) children responded to treatment according to one or both primary outcomes; uroflow configuration (50%) and PVR (28%). DI resolved in 12 (26%) children and 27 of the 32 children, who prior to the treatment had recurrent UTIs experienced no UTIs during the follow up period. The use of anticholinergics was a significant negative predictor for response to treatment. We found that almost half of the responders (48%) reached effect prior to the fourth visit.

DISCUSSION

Biofeedback assisted PFMT can improve the symptoms in children with DV. When comparing to existing literature we find a less pronounced effect of the intervention. A possible explanation may be that the children enrolled in this study were recruited from a tertiary referral centre and were all refractory to standard urotherapy. Moreover, the difference in patient characteristics and treatment protocols between different studies make direct comparisons of efficacy difficult.

CONCLUSION

Physiotherapeutic intervention with biofeedback assisted PFMT seems to lead to better uroflow patterns in approximately 60% of cases in DV improving the uroflow curves and PVR, however improvement in uroflowmetry patterns is not necessarily reflected in the resolution of incontinence or UT symptoms. The use of anticholinergics seems to be a negative predictor for response to treatment.

Prospective evaluation of the connected biofeedback EMY Kegel trainer in the management of stress urinary incontinence

INTRODUCTION

The aim of this study was to evaluate changes in the quality of life with the connected biofeedback EMY Kegel trainer in patients suffering from stress urinary incontinence. Materiel and methods: This was a prospective, single-center, non-comparative study, which took place between September 2019 and October 2020, in the University Hospitals of Strasbourg. Eligible patients were instructed to use the EMY probe for a minimum of 10 min per day for five days per week. To assess quality of life and urinary symptoms, the Contilife and ICIQ-SF scores were completed each month until the final visit (M3). The PGI-I was also completed at 3 months to assess the benefit of the EMY Kegel Trainer.

RESULTS

A total of 55 patients were included. At the inclusion visit (M0), the mean Contilife and ICIQ-SF scores were respectively at 6.6 ± 1.5 and 10.5 ± 3.0 points. At the final visit (M3), the mean Contilife score increased to 9.2 ± 1.0, indicating an improvement in quality of life. The mean ICIQ-SF score decreased to 4.2 ± 4.0, indicating an improvement in urinary symptoms. The PGI-I questionnaire identified a positive assessement of the EMY Kegel trainer. On the 55 patients included, 35 (64%) reported completing at least 36 sessions during the study, i.e. an average of 3 sessions per week.

CONCLUSIONS

This study suggests that perineal rehabilitation by biofeedback using the EMY Kegel trainer might be beneficial.
