Patients with interstitial lung disease present, in addition to respiratory symptoms, peripheral muscle dysfunction, which contributes to functional impairment. The aimof the study is to investigate the safetyof whole-body electrical stimulation in patients with interstitial lung disease (ILD). Patients Will perform two different EECI protocols, with na intervalo fone week between them. First the patients Will be submitted to the evaluation of the autonomic control. After a blood collection and measurement of muscles trength will be performed. The verification of vital signs: BP, SpO2, HR, FR and the perception of dyspnea and fatigue (BORG) Will occur immediately before and after the EECI session. During the protocol, SpO2, HR, RR and BORG Will be checked. After the session, a new blood collection Will be performed and autonomic control and muscle strength Will be reassessed. After 24, 48 and 72 hours, new blood samples Will be collected and muscle pain Will be measured.
Patients with ILD will be submitted to two whole body electrostimulation protocols, with an interval of one week between them. Miha Bodytec equipment will be properly calibrated, with electrodes on the quadriceps, hamstrings, glutes, biceps, triceps, pectorals, abdomen, trapezius, latissimus dorsi and quadratus lumborum muscles. Symmetric pulsed biphasic current will be used, pulse width of 400µs, frequency of 75Hz, contraction time of five seconds, rest time of 10 seconds. Protocol 1 will take eight minutes resulting in 32 muscle contractions, and protocol 2 will take 16 minutes resulting in 64 muscle contractions. Initially, patients will undergo an assessment of autonomic control. Then, blood collection will be performed, the serum lactate level will be checked and muscle strength will be measured. Verification of systolic blood pressure, diastolic blood pressure, peripheral oxygen saturation, heart rate, respiratory rate and perception of dyspnea and fatigue (BORG) will occur immediately before and after the whole body electrical stimulation session. During the protocol, peripheral oxygen saturation, heart rate, respiratory rate and BORG will be checked. After the session, the serum lactate level will be checked, a new blood collection will be performed and autonomic control and muscle strength will be reassessed. After 24, 48 and 72 hours, new blood samples will be collected and muscle pain will be measured.

| Label | Type | Description | Intervention Names |
|---|---|---|---|
| whole-body electrical stimulation, Protocol 1 | Experimental | A whole body electrical stimulation session. Symmetrical biphasic current will be used, pulse width of 400µs, frequency of 75Hz, contraction time of five seconds, rest time of 10 seconds, for eight minutes, totaling 32 muscle contractions. During the first two minutes of stimulation, the patient will remain in isometry to become familiar with the electrical current. Then with the use of a stick (for proprioception), a series of biceps exercises and a series of triceps exercises, a series of sit-ups and a squat, a series of step ups and downs, and a series of plantings. |
