About this study
Official title: Effect of Preoperative Pulsed Electromagnetic Field and Abdominal Exercises on Muscle Strength Post Ventral Hernioplasty
The aim of this study is to investigate the impact of a preoperative pulsed electromagnetic field and abdominal exercises on muscle strength post ventral hernioplasty.
Read the detailed description
Sixty patients, 25-40 years old, diagnosed with a ventral hernia and consulted for surgical hernia repair, preoperatively, were randomly assigned either into pulsed electromagnetic therapy and graduated abdominal strengthening exercises group (group A), graduated abdominal strengthening exercises group (group B), pulsed electromagnetic therapy group (group C) or group D who is instructed to presume in normal activities of daily living preoperatively, without any abdominal exercises or PEMF. All treatment interventions were applied at a frequency of three sessions per week for six weeks preoperatively. Abdominal muscle torque was measured by a biodex isokinetic dynamometer preoperatively at baseline and after six weeks of intervention and after four months postoperatively.

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
Pulsed electromagnetic fieldOther
Pulsed electromagnetic field therapy was applied directly over the abdominal muscle from a supine position after the removal of metals or things that can be affected by a magnetic field will be assured prior to magnetic field application. The treatment parameters were set as 15 Hz frequency, 20 gauss amplitude with a rectangular waveform for 20 minutes.
Graduated abdominal strengthening exercisesOther
Four specific muscle core exercises were performed
| Study group | Role | What they receive |
|---|---|---|
| Pulsed electromagnetic field and selected graduated abdominal exercises (group A) | Experimental | The interventions were done preoperatively, received pulsed electromagnetic therapy (PEMFT) on abdominal muscles,15 Hz frequency, 20 gauss amplitude with a rectangular waveform, for 20 minutes then they performed the selected graduated abdominal strengthening exercises for 30 minutes, three sessions per week for six weeks. Receives: Other: Pulsed electromagnetic field; Other: Graduated abdominal strengthening exercises |
| Selected graduated abdominal exercises (group B) | Active comparator | The interventions were done preoperatively, patients performed the selected graduated abdominal strengthening exercises for 30 minutes, three sessions per week for six weeks. Receives: Other: Graduated abdominal strengthening exercises |
| Pulsed electromagnetic field (group C) | Active comparator | The interventions were done preoperatively, they received pulsed electromagnetic therapy (PEMFT) on abdominal muscles,15 Hz frequency, 20 gauss amplitude with a rectangular waveform, for 20 minutes only. Receives: Other: Pulsed electromagnetic field |
| Control group | No intervention | Patients were instructed to presume in normal activities of daily living preoperatively, without any abdominal exercises or PEMFT. |
What is being measured
The primary outcome is the main question the study is designed to answer.
the change in the abdominal muscle torque
measured by biodex isokinetic
Measured: Baseline and six weeks after the intervention preoperatively and after four weeks postoperative as follow up

Questions about this trial
What is this clinical trial studying?
A study testing Pulsed electromagnetic field and Graduated abdominal strengthening exercises in people with Hernia, Ventral, run by Cairo University at 1 site in Egypt.

Who may be eligible to take part?
The sponsor lists 4 inclusion and 7 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: finished, as of the sponsor's last update on 14 Feb 2023. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 1 site in Egypt. 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?
The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
the change in the abdominal muscle torque (time frame: Baseline and six weeks after the intervention preoperatively and after four weeks postoperative as follow up). 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 14 Feb 2023; AzTrials last refreshed its copy on 7 Nov 2026.
