Clinical Trial 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.

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.

Intervention

Other:
• Whole-body electrical stimulation
The protocol with whole-body electrical stimulation will begin in the intensive care unit and will be completed in the inpatient unit. To stimulate all proposed muscle groups, self-adhesive electrodes will be positioned bilaterally on the quadriceps femoris, tibialis anterior, biceps brachii and lower rectus abdominis muscles. The frequency of 75 Hz will be adopted and the intensity will be adjusted to cause visible muscle contraction. The progression of the therapy protocol will occur throughout the sessions aiming to reach 20 minutes of therapy and 80 contractions.
• Routine physical therapy
The protocol will be based on knee and hip flexion and extension movements; hip adduction and abduction; flexion and extension of shoulders, elbows and wrists; shoulder abduction and adduction; respecting the range of each joint. Volunteers will also perform transfers from lying to sitting and standing positions. Respiratory conduct will be based on ventilation patterns, bronchial hygiene maneuvers and cough.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Isometric quadriceps muscle strength.	Isometric quadriceps muscle strength will be evaluated using a portable dynamometer.	Time 0 (baseline) and immediately after 15 sessions (totaling a maximum of 3 weeks).
Primary	Lower limb muscle strength.	Lower limb strength will be carried out using the 10-repetition sit-and-stand test (SST).	Time 0 (baseline) and immediately after 15 sessions (totaling a maximum of 3 weeks).
Primary	Mortality.	Mortality will be assessed by counting the number of deaths occurring in the study and after hospital discharge.	Mortality will be assessed after 30 days, after 60 days and up to 1 year after lung transplantation.
Secondary	Safety of whole-body electrical stimulation.	Safety of whole-body electrical stimulation will be assessed by measuring peripheral oxygen saturation.	Time 0 (pre intervention), after 10 minutes and at 20 minutes from the beginning of the intervention.
Secondary	Safety of whole-body electrical stimulation.	Safety of whole-body electrical stimulation will be assessed by measuring heart rate.	Time 0 (pre intervention), after 10 minutes and at 20 minutes from the beginning of the intervention.
