Effect of Neuromuscular Electrical Stimulation on Muscle Mass in ECMO Patients (NMES-ECMO)

30. april 2026 oppdatert av: Ehssan Rabie, Cairo University

Effectiveness of Neuromuscular Electrical Stimulation in Critically Ill Patients Undergoing Extracorporeal Membrane Oxygenation

The goal of this clinical trial study: is to determine the effectiveness of neuromuscular electrical stimulation in critically ill patients undergoing extracorporeal membrane oxygenation.

The main questions it aims to answer are:

  • Does NMES has an effect when added to conventional protocol for ECMO patients?
  • Does NMES will help in preserve muscle mass?
  • Patients will recieve the treatment untill discharge.
  • Assesment will be done before and after treatement

Detaljert beskrivelse

  1. Subjects:

    Fifty Patients from both genders with pulmonary or cardiac disease receiving extracorporeal membrane oxygenation will participate in this study. They will randomly have divided into two groups equal in numb.Their ages will be ranged from 20 to 50 years.

  2. Design of the study:

In this study the patients will be randomly assigned into two equal groups (25 patients for each group):

  1. Group A (Study group):

    This group includes 25 patients who will receive VMS current of NMES on quadriceps muscle bilateral for 30 min daily for one week in addition to conventional physiotherapy program (Range of motion exercises, Positioning,Strengthening exercises and Stretching exercises).

  2. Group B (Control group):

This group will include 25 patients. The participants will receive conventional physiotherapy program (Range of motion exercises, Positioning,Strengthening exercises and Stretching exercises) two times per day for one week.

- Equipments:

Measurement equipments:

A-Evaluating muscle strength The Medical Research Council (MRC) Scale for Muscle Strength B-Evaluating muscle mass Ultrasonography for assessing quadriceps muscle mass applied by ACUSON P500 manufactured by SEIMENS made in USA C-Evaluating level of activity ICU Mobility scale (IMS): IMS provides a sensitive 11-point ordinal scale, ranging from nothing (lying/passive exercises in bed, score of 0) to independent ambulation (score of 10).

D- Hospital length of stay (LOS) days E-Discharge destination Discharge destination was ranked on an ordinal scale: 0 = mortality; 1 = discharge to inpatient hospice; 2 = discharge to long-term acute care facility equivalent to ventilator weaning and skilled nursing facilities; 3 = discharge to acute and subacute care rehabilitation facilities; 4 = discharge to home with home health rehabilitation services; and 5 = discharge to home with no services.

F- Incidence and type of ECMO complication

- Treatmenet Procedures: NMES will be applied by using DJO/ Chattanooga - USA 2023 Patients on ECMO will receive daily 30-minute of neuromuscular electrical stimulation VMS current / on the quadriceps femoris muscles (rectus femoris and vastus intermedius) bilaterally as long as they were on ECMO to preserve muscle mass. Patients will be supine lying with knee slight flexion 40 degree by billow. 2 rectangular carbon electrodes (6×8 cm) on the muscle motor point, Frequency 50 pps , with a 1000 usec phase duration, ramp 5 sec, duty cycle 1:5.

The conventional program for both groups:

(Early mobilization started passively and progressed to be active, and progressed from in bed mobility to out of bed mobility, Mobilization activities, Passive- and active-assisted movements of extremities, Sitting on a chair, Bedside standing, Walking with support).

Intervention Name: Neuromuscular Electrical Stimulation (NMES) + Conventional Physiotherapy Intervention Type: Other

Intervention Description:

Patients will receive neuromuscular electrical stimulation (NMES) in addition to a conventional physiotherapy program while undergoing ECMO.

NMES will be applied bilaterally to the quadriceps femoris muscles using a VMS current for 30 minutes daily for one week. Stimulation parameters will include a frequency of 50 pulses per second, pulse duration of 1000 microseconds, ramp time of 5 seconds, and a duty cycle of 1:5. Two rectangular carbon electrodes (6 × 8 cm) will be placed over the motor points of the targeted muscles. Patients will be positioned in a supine position with slight knee flexion (approximately 40 degrees).

In addition, they will receive a conventional physiotherapy program twice daily(passive and active-assisted range of motion exercises, bed mobility, sitting, standing, and ambulation).

Intervention Name: Conventional Physiotherapy Program Intervention Type: Other

Intervention Description:

Participants will receive a conventional physiotherapy program only, administered twice daily for one week during ECMO support. The program will include early mobilization starting with passive movements and progressing to active-assisted and active exercises as tolerated.

Rehabilitation activities will include in-bed mobility, sitting at the edge of the bed, standing, and assisted ambulation based on patient condition and tolerance. No neuromuscular electrical stimulation will be applied in this group.
Atferdsmessig: Conventional physiothrapy program

Participants in this group will receive a conventional physiotherapy program only during extracorporeal membrane oxygenation (ECMO) support. The program will be administered twice daily for one week.

The intervention will include early mobilization strategies starting with passive range of motion exercises and progressing to active-assisted and active exercises as tolerated. Rehabilitation activities will include bed mobility, sitting at the edge of the bed, bedside standing, and assisted ambulation according to patient tolerance and clinical stability.

All interventions will be delivered according to standard ICU physiotherapy practices. Neuromuscular electrical stimulation (NMES) will not be applied in this group.

Tidsramme
Change in quadriceps muscle mass
Tidsramme: Baseline and after 7 days of intervention
Quadriceps muscle mass will be assessed using ultrasonography by measuring muscle thickness and/or cross-sectional area of the rectus femoris muscle. Measurements will be performed at baseline (before intervention) and after one week of intervention during ECMO support. The primary endpoint will be the change in muscle mass over time between groups.

Discharge destination
Tidsramme: From day 1 up to 90 days

Discharge destination will be assessed using an ordinal scale:

0 = mortality;

  1. = inpatient hospice;
