Brief Summary

Surgical removal of the prostate (radical prostatectomy) is the most common therapy in prostate cancer patients. However, urinary incontinence often occurs as a side effect. Although this can recede after a few weeks or months, 12 months after prostatectomy 17 - 34 % of the patients are still incontinent. An effective measure to reduce incontinence is pelvic floor muscle or sphincter training. Various methods exist for this, from pelvic floor gymnastics to training with biofeedback devices and electrical stimulation methods. Kieser Training, a Germany-wide provider of health-oriented resistance training, has a training device for pelvic floor muscle training. It is a biofeedback device that can be used in public training rooms and does not have to be inserted or glued intimately as with comparable methods. The standardized training program and concept, which allows non-invasive training in public space, has not been evaluated yet. The aim of the RECON study is to investigate whether Kieser resistance training with integrated Kieser pelvic floor muscle training is as effective as (non-inferior to) Kieser resistance training plus conventional pelvic floor muscle exercise to reduce urinary incontinence in prostate cancer patients after radical prostatectomy. The primary endpoint is the proportion of patients with urinary incontinence at the end of a 12-week training phase (using the 24h pad test). The secondary endpoints are changes in urinary leakage, other incontinence symptoms, incontinence-related quality of life, body composition and changes in strength and overall quality of life. The design is a two-arm randomized controlled trial with 180 prostate cancer patients. After the initial examination patients will be randomized to one of two groups. Patients in both groups will train for about 60 minutes twice a week for twelve weeks and additionally perform daily tension exercises at home. Patients in group A will perform the resistance training unit with the pelvic floor biofeedback device A5 from the Kieser Training AG and patients of group B will perform the resistance training unit without the pelvic floor biofeedback device A5 and undergo conventional pelvic floor muscle training with a physiotherapist once a week before the resistance training unit starts. The Recon study will be conducted at the Kieser Training Studio in Offenbach, as a cooperation project of the National Center for Tumor Diseases (NCT), Heidelberg University Hospital and the Kieser Training AG with the Kieser Training franchisee (studio owner) as PhD student at the NCT. The Kieser Training AG is not a sponsor and the study is neither financed nor sponsored.

Outcome Measures

Primary Outcomes (1)

  • Change from baseline to week 12 of the proportion of continent patients

    Major efficacy endpoint (primary endpoint) is the proportion of patients who is continent 12 weeks, with continence defined as no need to wear a pad (1 pads) in the 24 h pad test. The International Consultation on Incontinence (organized by the International Consultation on Urological Diseases) recommends that criteria for cure/improve/fail of interventions against urinary incontinence should be based on patient perception as well as objective and semi-objective instruments such as validated questionnaires, diaries and pad tests. In the RECON study, the 24 h pad test will be used as an objective measure of incontinence.

    baseline up to 12 weeks (& 3 month follow-up)

Secondary Outcomes (6)

  • Change from baseline to week 12 in urinary leakage (cumulative pad weight in the 24 h pad test

    baseline up to 12 weeks (& 3 month follow-up)

  • Change from baseline to week 12 in Health related Quality of life, as measured by the EORTC QLQ-C30

    baseline up to 12 weeks (& 3 month follow-up)

  • Change from baseline to week 12 in incontinence related quality of life (EORTC QLQ PSM module)

    baseline up to 12 weeks (& 3 month follow-up)

  • Change from baseline to week 12 in pain experienced (visual analog scale, VAS)

    baseline up to 12 weeks (& 3 month follow-up)

  • Change from baseline to week 12 in muscle strength (Delfex Sensor System, DSS)

    baseline up to 12 weeks (& 3 month follow-up)

  • +1 more secondary outcomes

Study Arms (2)

Resistance training on the Kieser A5 pelvic floor trainer

EXPERIMENTAL

Participants will receive a supervised full body resistance exercise program with 10-12 machines twice weekly. The resistance training for the experimental group includes an intervention program on the Kieser A5 pelvic floor trainer. The training is a predetermined program of the Kieser Training AG. A standardized instruction protocol and custom settings of the seat minimize training or measurement variations. The exercise on the Kieser A5 pelvic floor muscle trainer is standardized and will take 120 s in total which is based on current training theories.

Behavioral: Resistance training including the Kieser A5 pelvic floor trainer

ACTIVE COMPARATOR

Participants will receive a supervised full body resistance exercise program with 10-12 machines twice weekly. Participants in the active comparator group perform the resistance training unit without the pelvic floor biofeedback device A5 and undergo conventional pelvic floor muscle training with a physiotherapist once a week before the resistance training unit starts. Participants are individually informed about the anatomy and function of the pelvic floor muscles and how to correctly contract them. The methodical structure for the movement therapy after prostatectomy suggests that the participants first lay down, then go in the seat, then above the all fours position stand in the upright position tt be treated. Each exercise lasts 3 to 5 min and the session lasts around 20 - 30 min.

Interventions

In the RECON Study participants of both arms will receive machine-based resistance training. Experimental group will additionally train with Kieser A5 pelvic floor trainer.
