Trial Review

Did you know?

The ANZCTR now automatically displays published trial results and simplifies the addition of trial documents such as unpublished protocols and statistical analysis plans.

These enhancements will offer a more comprehensive view of trials, regardless of whether their results are positive, negative, or inconclusive.

The safety and scientific validity of this study is the responsibility of the study sponsor and investigators. Listing a study does not mean it has been endorsed by the ANZCTR. Before participating in a study, talk to your health care provider and refer to this information for consumers

Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
This is a prospective, single blinded pilot randomised controlled trial with concealed allocation, blinded assessors and intention to treat analysis. In addition to usual care, participants allocated to the intervention group will be invited to attend a group-based, weekly hydrotherapy class for 8 weeks supervised by a Physiotherapist. All hydrotherapy sessions will be a maximum of one hour in duration and will take place within the Physiotherapy Department. The structure of the hydrotherapy sessions will include a warm up, targeted exercises and cool down. Exercises will include but are not limited to walking in water, pelvic floor exercises, pelvic stretches and relaxation, deep water walking, pendular exercises and sea weeding. Session attendance and adherence to the exercises will be monitored by an exercise chart kept in a folder with the Physiotherapist providing the hydrotherapy intervention. This is a different Physiotherapist to that providing usual care.
Intervention code [1] 315935 0
Treatment: Other
Comparator / control treatment
The control group will be provided with usual care interventions for those patients referred to the Royal Brisbane and Women's Hospital Physiotherapy Department for persistent pelvic pain due to endometriosis. Usual care is a multimodal approach whereby treatment interventions are based on a comprehensive assessment undertaken at the time of the patient’s initial appointment with the service. A broad overview of the interventions that may be undertaken during a patient’s episode of care with the service include:
• Pelvic Floor relaxation exercises
• Visualisation techniques
• Deep Tissue Release of the Pelvic Floor
• Contract – relax techniques
• Avoidance of maximal pelvic floor exercises
• Pressure Biofeedback
• EMG Biofeedback
• Dry needling
• General exercise regimes
• Dietary advice specific to Physiotherapy management of Persistent Pelvic Pain
Control group
Active

Outcomes
Primary outcome [1] 321999 0
Pelvic floor function
This outcome will be measured using the Australian Pelvic Floor Questionnaire (APFQ) which is a validated instrument used to record pelvic floor symptoms, in addition to bladder, bowel and sexual function, pelvic organ prolapse and condition specific quality of life
Timepoint [1] 321999 0
Baseline and at the 8-week follow-up
Primary outcome [2] 321826 0
Pain will be assessed by Visual Analogue Scale (VAS).
Timepoint [2] 321826 0
This measure will be collected by a blinded assessor at baseline and the 8-week follow-up
Primary outcome [3] 321846 0
Pelvic pain impact
This outcome will be measured using the Pelvic Pain Impact Questionnaire (PPIQ), an instrument used to measure the impact of pelvic pain on quality of life.
Timepoint [3] 321846 0
Baseline and at the 8-week follow-up
Secondary outcome [1] 376447 0
Attendance rates will be assessed by an attendance log kept by the Physiotherapist providing the hydrotherapy.
Timepoint [1] 376447 0
Time point will be at completion of the study. It is anticipated that the trial will take 2 years to complete.
Secondary outcome [2] 376448 0
Cost differentials will be assessed by calculating the cost differential between resources used for providing usual care and attendance at group hydrotherapy sessions. Physiotherapy WAUs will be used to calculate labour costs. A record of appointments will come from hospital medical records and hydrotherapy attendance logs. A log will be kept of the parking costs reimbursed to patients.
Timepoint [2] 376448 0
Time point will be at completion of the study.
Secondary outcome [3] 376371 0
Generic health status using the EQ-5D-5L
Timepoint [3] 376371 0
Baseline and 8 week follow up
Secondary outcome [4] 377143 0
Acceptability of the programme will be determined using a purpose built questionnaire related to satisfaction with components relevant to the programme. A subset of questions will be identical for both intervention and control groups, with remaining questions relevant to the intervention received.

Can healthy volunteers participate?
No
Key exclusion criteria
Exclusion criteria include:

• Conditions that contra-indicate hydrotherapy (open wounds, active infection, heat sensitive condition, fear of water)
• Physiotherapy treatment for the same condition within the last 6 months
• Severe psychiatric history where it is judged that safety during hydrotherapy may be compromised
• Non-English speaking background where an accredited interpreter is required to be present
• Concomitant diagnosis of Fibromyalgia
• Unable to commit to the 8-week intervention period
• Post-menopausal (as defined by absence of menses for 12 months without a pathological cause. The average age at which this occurs is 51.4 years)

Efficacy
Statistical methods / analysis
Analysis would initially consist of a baseline comparison for demographic and clinical variables. Due to the small sample size, group-by-time interactions for the primary outcomes of interest (i.e. Pain VAS, PPIQ and EQ-5D-5L) will be analysed using non-parametric statistics (e.g. Friedman test), while within-group differences over time will be analysed using Wilcoxon signed-rank tests. Cost and feasibility analyses will be assessed against usual care alone in relation to clinician time costings, waiting list impact and expense data collected.
Patient-related experience and satisfaction surveys will be presented descriptively where identical items between the two cohorts will be compared using Mann-Whitney U tests.
Service utilisation between the intervention groups will be compared descriptively. The net financial position of each intervention group will be calculated based upon the total estimated revenue (attracted through attended appointments) less total estimated costs (through direct labour and non-labour expenses) incurred during the intervention period.
