- Brief Summary
This study aims to evaluate the effects of whole-body electrical stimulation (WB-EMS) in the rehabilitation of patients undergoing lung transplantation. This is a randomized clinical trial with patients from the inpatient unit of Dom Vicente Scherer Hospital of Irmandade Santa Casa de Misericórdia from Porto Alegre (ISCMPA) who will be allocated to a control group (which will receive physiotherapy from routine) or intervention group (which will receive physiotherapy from routine and WB-EMS). Interventions with WB-EMS will occur every day from the moment of extubation until hospital discharge (15 sessions per patient). Assessments will be carried out pre-lung transplantation, after extubation, during intervention protocols and at the time of hospital discharge.
- Detailed Description
Patients on the lung transplant list may experience post-procedure complications that culminate in a higher risk of mortality, which are related to primary and chronic graft dysfunction and infections. These complications are partly responsible for prolonged immobility, sarcopenia, decline in functional capacity and deterioration in quality of life. There is evidence that physical rehabilitation, mainly through exercise, improves the physical capacity and quality of life of transplant patients. However, not all patients are able to perform this type of activity due to low tolerance for it. In this sense, WB-EMS can be an alternative for early rehabilitation. This study aims to evaluate the effects of WB-EMS in the rehabilitation of patients undergoing lung transplantation.
Patients will be selected from the Pulmonary Rehabilitation Center of Pereira Filho Hospital prior to lung transplantation and the following assessments will be carried out: muscle architecture and quality (ultrasound), peripheral muscle strength (dynamometry of lower and upper limbs, Medical Research Council scale and 10-repetition sit-and-stand test), respiratory muscle strength (manovacuometry) and functional capacity (six-minute walk test). After the transplant, with the patient admitted to the intensive care unit, and after being extubated, blood sample will be collected to measure muscle damage, also it will be evaluated the muscle architecture and quality, peripheral muscle strength (only using the Medical Research Council scale) and respiratory muscle strength. Prior to hospital discharge, muscle architecture and quality, peripheral muscle strength (dynamometry of lower and upper limbs, Medical Research Council scale and 10-repetition sit-and-stand test), respiratory muscle strength, functional capacity, and muscle damage will be reassessed, along with the length of hospital stay.
During the training period, the safety of the therapy will be assessed by monitoring cardiorespiratory parameters, muscle pain (analogic visual scale) and fatigue (Borg subjective perceived exertion scale).
Patients will be randomized to the control group (GC) (which will receive physiotherapy from routine) or the intervention group (GI), which will perform whole-body electrical stimulation using the equipment ReCARE® (Visuri, Minas Gerais, Brazil), in addition to routine physiotherapy. After extubation, patients will begin the protocol for 15 sessions and will be reevaluated, therefore the protocol begins in the intensive care unit and will be completed in the inpatient unit.

Group Intervention Description Routine physical therapy Routine physical therapy Patients in the control group (active comparator) will receive routine hospital physical therapy until the moment of hospital discharge. No intervention with electrical stimulation will be performed in this group. Whole-body electrical stimulation (WB-EMS) Whole-body electrical stimulation WB-EMS will be performed with ReCare® equipment (Visuri, Minas Gerais, Brazil). Patients will perform sessions once a day, totaling a maximum of 15 sessions. In addition to the WB-EMS protocol, the patients will receive routine physiotherapy at the hospital.
- Primary Outcome Measures
Name Time Method Isometric quadriceps muscle strength. Time 0 (baseline) and immediately after 15 sessions (totaling a maximum of 3 weeks). Isometric quadriceps muscle strength will be evaluated using a portable dynamometer.
Lower limb muscle strength. Time 0 (baseline) and immediately after 15 sessions (totaling a maximum of 3 weeks). Lower limb strength will be carried out using the 10-repetition sit-and-stand test (SST).
Mortality. Mortality will be assessed after 30 days, after 60 days and up to 1 year after lung transplantation. Mortality will be assessed by counting the number of deaths occurring in the study and after hospital discharge.
- Secondary Outcome Measures
Name Time Method Safety of whole-body electrical stimulation. Time 0 (pre intervention), after 10 minutes and at 20 minutes from the beginning of the intervention. Safety of whole-body electrical stimulation will be assessed by perceived exertion with the modified Borg Scale.This scale classifies effort from 0 (nothing at all) to 10 (maximum).
Respiratory muscle strength. Time 0 (baseline), on the first day after extubation and immediately after 15 sessions (totaling a maximum of 3 weeks). Respiratory muscle strength will be measured using the digital manovacuometer.
Functional capacity. Time 0 (baseline) and immediately after 15 sessions (totaling a maximum of 3 weeks). Functional capacity will be assessed using the six-minute walk test (6MWT).
Length of hospital stay. From randomization to discharge or death from any cause, whichever comes first, assessed up to 3 months. Length of hospital stay will be based on the number of days between the date of admission and hospital discharge.
Overall muscle strength. Time 0 (baseline), on the first day after extubation and immediately after 15 sessions (totaling a maximum of 3 weeks). To assess global muscle strength, the Medical Research Council (MRC) scale will be used. The total score ranges from 0 (quadriplegia) to 60 points (preserved muscle strength).
Isometric muscle strength of the elbow flexors. Time 0 (baseline) and immediately after 15 sessions (totaling a maximum of 3 weeks). The muscle strength of the upper limbs will be assessed through isometric contraction of the elbow flexor muscles with a portable dynamometer.
Muscle pain. Time 0 (pre intervention), after 10 minutes and at 20 minutes from the beginning of the intervention. Muscle pain will be measured with the analogic visual scale (AVS). This scale classifies pain from 0 (not at all) to 10 (maximum).
Upper limb muscle strength. Time 0 (baseline) and immediately after 15 sessions (totaling a maximum of 3 weeks). Palmar handgrip will also be assessed using an analog hydraulic dynamometer.
Muscle architecture. Time 0 (baseline), on the first day after extubation and immediately after 15 sessions (totaling a maximum of 3 weeks). The muscle architecture will be evaluated for the acquisition of ultrasound images of the vastus lateralis, rectus femoris, biceps brachii and rectus abdominis muscles, using a high-resolution ultrasound.
Muscle damage. On the first day post extubation and immediately after 15 sessions (totaling a maximum of 3 weeks). Muscle damage will be assessed by dosage of lactate dehydrogenase.
