Electric pulses and diet: a new weapon against muscle loss in stomach and bowel cancers?
NCT ID NCT06414122
First seen Jul 27, 2026 · Last updated Jul 28, 2026 · Updated 1 time
Summary
This trial tests whether a combination of whole-body electromyostimulation (WB-EMS) — a technology that uses electrical impulses to make muscles contract — and nutritional therapy can help people with certain gastrointestinal cancers preserve muscle mass. Participants include those with esophageal, stomach, duodenal, or colorectal cancer who have had surgery. The study compares WB-EMS plus nutritional coaching against conventional exercise and nutritional advice over 12 weeks.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- mid-frequency whole-body electromyostimulation (WB-EMS) combined with nutritional therapy
- What this could lead to
- If effective, this approach could offer a drug-free way to help people with gastrointestinal cancers maintain muscle mass and physical function during and after treatment.
- What could go wrong
- This is a relatively small, early-stage trial. The benefits of WB-EMS for muscle preservation in this specific cancer population are not yet proven, and the training requires medical clearance and may not be suitable for everyone.

Inclusion Criteria: * Patients with oesophageal, gastric, duodenal, colon or rectal cancer following surgery without further therapy and with neoadjuvant and adjuvant therapy * medical clearance for exercise training * written declaration of consent from the study participant Exclusion Criteria: * Participation in another study on the topic of exercise or nutrition * Electronic implants such as pacemakers, pumps, and coronary stents * Cardiac arrhythmia * Implants in the area of application (e.g. breast implants) * Pregnancy * Epilepsy * Wounds and open skin diseases in the area of application of the electrodes * Unhealed operations or bone fractures * Acute inflammatory diseases (e.g. inflammation of the intervertebral discs, bones, vessels, or soft tissue) * Directly after herniated discs or other instabilities such as large abdominal wall hernias * Blood clots (thromboses) * Bone diseases with high-grade osteoporosis * Increased risk of haemorrhage * Fever and illnesses that can be aggravated by physical exertion * Untreated high blood pressure * Blindness * Continuous parenteral nutrition * Metal and electronic parts in the body (e.g. prostheses, metal vascular clips, hearing aids/inner ear/cochlear implants, magnetic dental prostheses, pacemakers, contraceptives)
