About this study
Official title: The Effect of Postpartum Pelvic Floor Rehabilitation in Prevention and Treatment of Pelvic Floor Dysfunction- a Multiple Centers Cooperation Research.
Pregnancy and childbirth are considered as risk periods for injuries to the pelvic floor and development of pelvic floor dysfunction. This may leed to devastating loss of function and quality of life.The aim of this study is to evaluate the effect of postpartum pelvic floor muscle training with the device "PHENIX Neuromuscular Stimulation Therapy Systems" on the recovery of pelvic floor function for primiparous women.
- Being tested
- PHENIX Neuromuscular Stimulation Therapy System device, usual home care without device

Questions about this trial
What is this clinical trial studying?
A study testing PHENIX Neuromuscular Stimulation Therapy System device and usual home care without device in people with Primiparous Women With Singleton Baby at Term, run by Peking Union Medical College Hospital at 4 sites in China.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 4 inclusion and 13 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: status not confirmed, as of the sponsor's last update on 20 Aug 2013. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 4 sites in China. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
Are results available for this study?
Results are not available in the source record.
How can a doctor refer a patient or contact the research team?
Contact Lan Zhu (86-10-69156238, zhu_julie@sina.com), or a site near the patient. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
strength of deep muscle fiber I (time frame: 42 days after delivery). The study lists 18 primary outcomes in all. It is what the study was designed to measure, not a finding.
Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 20 Aug 2013; AzTrials last refreshed its copy on 8 Nov 2026.
