Evaluation of a supervised multi-modal physical exercise program for prostate cancer survivors in the rehabilitation phase: Rationale and study protocol of the ProCaLife study

[Effectiveness of early pelvic muscle training on pelvic floor strength, urinary incontinence symptoms, sexual function, and quality of life in post-radical prostatectomy patients: Systematic review of randomized clinical trials]

This study aimed to evaluate the effectiveness of early pelvic muscle training in reducing urinary incontinence symptoms, improving quality of life, sexual function, and increasing pelvic floor strength in post-radical prostatectomy patients. A search was carried out in 8 databases until October 26, 2022, the methodological quality and the risk of bias of 14 included studies (n=1236) were evaluated, moreover, the evidence and the meta-analysis were calculated. The intervention significantly reduced urinary incontinence symptoms compared to a control group (SMD=-2.80, 95% CI=-5.21 to -0.39, P=.02), with significant heterogeneity (I2=83%; P=<.0001) and moderate evidence. In addition, it presented moderate evidence to improve quality of life, and very low evidence to improve sexual function and pelvic floor strength. These results should be viewed with caution due to the significant heterogeneity of the studies analysed.

What more comprehensive physiotherapy techniques than pelvic floor muscles training should be investigated in the context of post-prostatectomy? A narrative review

BACKGROUND

In a previous article, we have underlined the emerging level of evidence for the effectiveness of a more comprehensive functional physical therapy than solely pelvic floor muscles training (PFMT) for men after radical prostatectomy (RP). More and more authors suggest that physiotherapy programs should not focus only on the side effect of continence, but more generally on the interaction of continence disorders with all other side effects related to patient's physical and emotional functioning.

RESEARCH QUESTION

The aims of this narrative review are to highlight rehabilitation approaches unrelated to analytical PFMT that would seem relevant to consider in the future for post-RP men.

METHOD

Our narrative review sought to map the body of literature relevant to the primary objective (non-PFMT), supplementing the data from our previous review with additional recent articles that were not eligible due to not meeting the inclusion criteria for a systematic review.

RESULTS

After full text screening, 13 interventional studies have been selected. Intervention strategies were based on five major type of exercises: flexibility, synergism & co-activation, coordination & movement control, strength & endurance, aerobic & games therapy. Most of the studies of this narrative review focused on synergies, co-activations and movement control techniques that emphasized the deep abdominal muscles and PFMs reflexive activation. The wide variety of countries represented in the 13 studies with consistent results point to the potential effectiveness and replicability across various socio-cultural, ethnical, or religious contexts.

CONCLUSION

We found 13 studies from 9 different countries that provide a more complete rehabilitation approach than PFMT alone in men post-RP. Intervention strategies were built around five main types of exercises, with the majority of them emphasizing synergies, co-activations, and movement control techniques. In light of these data, we hope that future research will enable us to offer the most relevant and patient-centered physiotherapy treatment.

Role of chronic exercise on pelvic floor support and function

PURPOSE OF REVIEW

To summarize recent literature about the potential role of chronic exercise on pelvic floor support and function.

RECENT FINDINGS

Stress urinary incontinence is common during physical activity. Scant evidence suggests a dose-response association between higher volumes of exercise and urinary incontinence. Athletes do not appear to have greater pelvic floor muscle strength or worse pelvic floor support compared to nonathletes. Pelvic floor muscle electromyographic activity increases substantially as running speeds increase.

SUMMARY

Based on the current literature, no strong conclusions can be drawn about whether chronic exercise exerts a positive or negative influence on pelvic floor support and function. Adopting longitudinal research methodology that prospectively monitors exercise exposure and subsequent changes in pelvic floor support and function would help to reduce selection bias associated with cross sectional studies on groups of athletes.

Design of programs to train pelvic floor muscles in men with urinary dysfunction: Systematic review

AIMS

Pelvic floor muscle training (PFMT) is a first line conservative treatment for men with urinary dysfunction, but reports of its efficacy are variable. This study aimed to systematically review the content of PFMT programs used for urinary dysfunction in men.

METHODS

Electronic databases (PubMed, CINAHL, EMBASE, Cochrane, PEDro) were searched for studies that used PFMT in the treatment of adult men with urinary dysfunction. Details of PFMT treatment sessions and home exercise protocols were extracted. Criteria specific to PFMT were developed, based on the Consensus on Exercise Reporting Template, and applied to all studies to measure the comprehensiveness of the PFMT description in the manuscript.

RESULTS

Results from the 108 included studies indicate substantial heterogeneity in both the content of PFMT and the quality of reporting of the components of the exercise regimes. There was notable disparity in the muscles targeted by the interventions (and few focused on urethral control despite the use in management of urinary conditions) and the intensity of the programs (eg, 18-240 contractions per day). Most studies were missing key details of description of the PFMT programs (eg, the position in which the pelvic floor muscle [PFM] contraction was taught and how it was assessed, methods used to ensure exercise adherence).

CONCLUSIONS

Variation in content of PFMT programs is likely to contribute to variation in the reported efficacy for management of urinary dysfunction in men, and unclear description of the details of the evaluated programs makes it difficult to identify the effective/ineffective components.
