Clinical Trial Summary

Cesareans are a frequent procedure in obstetrics and 15.4% (95% CI, 9.9-20.9%) of women with cesareans still have pain at 3 months after delivery. Currently, self-massage of the scar is recommended to them. Post-cesarean pain is associated with psychological disorders (including, e.g., anxiety, depression). Tecar therapy could improve the healing and pain associated with cesareans and therefore improve women's quality of life and their satisfaction. Objectives: The principal objective is to study the analgesic efficacy of tecar therapy for postoperative scar pain and/or discomfort at 3 month after cesarean delivery, by comparing it with sham tecar therapy. A randomized clinical trial with 2 parallel arms and single blinding, to study the efficacy of this medical device for therapeutic purposes. In both groups (randomization stratified as a first cesarean or repeat cesarean), the women will have the standard recommended treatment - manual self-massage of the scar. Women's instruction in this self-massage will be structured and identical for both groups, including the provision of an informational document describing how to perform this massage. The training will be provided immediately after randomization. - Description of the experimental group These women will receive Tecar through Winback® technology [CE medical 1984, Norma 60601-2, ISO9001, ISO13485. Class IIa medical device, CET (capacitative mode) 400 VA and RET (resistant mode) 100 Watts, weight 4 Kg)]. Each session will last for 20 minutes, and each individual will have 3 sessions over a period of 3 weeks. - Description of the control group ("sham treatment") The women will follow the same study design as the experimental group with activation of the portable placebo device identical to the active medical. Each session will last for 20 minutes, and each individual will have 3 sessions over a 3-week period. Principal endpoint: Visual analogic scale (VAS) for pain and/or discomfort at 3 months after delivery partum (with a ruler scored from 0 for no pain to 10 for the worst pain imaginable). Succinct description of the products: "Tecar" is an acronym for a type of therapy (transfer electrical capacitive and resistive). The Winback® is a portable, easy-to-handle noninvasive regenerator. This study will use only the instrumental mode and 4-cm electrodes. During each session, this electrode will be moved over the entire scar. We will use the following 3 modes: capacitive (CET), CET Dynamic, and resistant (RET). These allow us to standardize the treatment without taking into account either the thickness of the abdominal wall or the woman's morphology. Each session will take 20 minutes (CET for 4 min, CET Dynamic 6 min, RET 6 min and CET 4 min). The intensity of CET and RET will be adapted to each woman and the diathermy chosen according to the woman's threshold of comfort, to be determined by her at each session, in the experimental group. There will be 1 session a week for 3 weeks. Study plan and procedures: The eligible women will be identified by the physicians in both of the obstetrics departments participating in this study. The women will receive oral information as well as written information. If they are interested, they will be offered an inclusion visit, normally scheduled for one week later. After a second verification of the eligibility criteria at this inclusion meeting, reading the information form and signing the consent, they will be randomized into one of the two groups by random drawing. Each woman will have 3 sessions (1 session a week for 20 min for 3 consecutive weeks): active treatment by tecar therapy or sham/placebo tecar therapy. They will receive self-administered questionnaires at 3 and 6 months after delivery to be completed and returned.


Description:

- Study design: A randomized clinical trial with 2 parallel arms and single blinding to study the efficacy of this medical device for therapeutic purposes. - Procedure for early withdrawal from the treatment: A woman can withdraw from the study early for the following reasons: - intercurrent disease interfering with the study organization and normal protocol procedures (i.e., prolonged hospitalization for a disorder other than gynecologic or obstetric), - death, - the woman's decision, - a major protocol deviation, - and loss to follow-up (a subject lost to follow-up is a participant who did not come to the visit planned in the protocol and for whom we lack information on which we could base a judgment. It is essential to attempt by all reasonable means to obtain information and learn the reason why these women withdrew from the trial. "Lost to follow-up" will be invoked only when the investigation has been unsuccessful). The trial may be stopped temporarily or permanently for the following reasons: - Recruitment too low or nonexistent, - Impossibility of obtaining funding for the trial, - Any directive by competent authorities requiring the temporary or permanent end of the trial, - Decision of the sponsor and of the investigator-coordinator. - Methods of recruitment Physician, in both obstetrics departments in which the study is planned will inform the women of the study during their postnatal consultation, planned by statute in France at 6 to 8 weeks after delivery. They will also be informed by posters displayed in the consultation sector of the two obstetrics departments. If they are willing, they will be offered the opportunity to participate in the study; if so, a telephone appointment will be arranged for re-verification of their eligibility criteria by the research midwives at the academic hospital of Estaing or the clinical research assistants at the Vichy Hospital Center. If she is indeed eligible for the study, an inclusion visit will be scheduled. At this visit, the investigator-physician will verify the file with the woman (review her history) and examine the woman (blood pressure and examination of the skin of and around the scar). She will also receive a more detailed note of information. After a conversation with the investigator, who will answer her questions, the woman can sign the consent form. The investigator will also sign the consent form. The women will receive structured training on how to massage the scar (and also a paper information about the massage of the scar) and their first session of treatment by tecar therapy (or sham tecar therapy) at the end of this inclusion visit. On average, the time to reflect between the first oral information about the study and the written consent signature will be one week.

Intervention

Device:
Winback® on
For this study, we will use only the instrumental mode and the 4-cm electrodes. During each session, this electrode will be moved over the entire scar, with the contact between electrode and the skin provided by an adequate quantity of conductive cream. We will use the following 3 modes: CET, CET Dynamic, and RET; these allow us to standardize the treatment without taking into account either the thickness of the abdominal wall or the woman's morphology. Each session will take 20 minutes (CET for 4 min, CET Dynamic 6 min, RET 6 min and CET 4 min). The intensity of CET and RET will be adapted to each woman and the diathermy chosen according to the woman's threshold of comfort, to be determined by her at each session. There will be 1 session a week for 3 weeks. Portable instrument is activated.
