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.

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.

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.

The interventions were done preoperatively, patients performed the selected graduated abdominal strengthening exercises for 30 minutes, three sessions per week for six weeks.

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.

Patients were instructed to presume in normal activities of daily living preoperatively, without any abdominal exercises or PEMFT.

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.

Baseline and six weeks after the intervention preoperatively and after four weeks postoperative as follow up
