Clinical Trial Summary

Unfortunately, hospital-acquired weakness is highly prevalent among COVID-19 hospitalized patients, who often require prolonged bed-rest or paralytics for an extended period of time in order to maintain oxygenation. Prolonged bed rest has been associated with pronounced loss of muscle mass that can exceed 10% over the 1st week, which leads to functional impairment and complications post-hospital discharge. Physical therapy and in-hospital mobility program may reduce the incident of hospital-acquired weakness, but they are often impractical for COVID-19 patients. In particular, conventional mobility programs are challenging for those who are being treated in an intensive Care Unit. The purpose of this study is to test feasibility and proof-of-concept effectiveness of daily use of lower extremity electrical stimulation (EE) therapy, as a practical solution to address lower extremity muscle deconditioning, to address chronic consequences of COVID-19 including hospital-acquired weakness.

Description:

20 subjects that were hospitalized due to severe COVID-19 infection and present neuromuscular complications (i.e., hospital acquired weakness due to neuromyopathy) will be recruited after the first phase of this study is completed. Unlike Phase I (study for prevention), this is a proof of concept randomized control trial (RCT) study for recovery. The patients will be recruited from the COVID-19 Clinic at Baylor College of Medicine and will begin the study after being diagnosed with neuromyopathy due to prolonged hospitalization for COVID-19. This will be performed by a critical care and pulmonary specialist at the BCM COVID-19 Clinic. The entire cohort will receive daily electrical stimulation in lower extremity (e.g. Gastrocnemius, tibial anterior muscle) up to 1 hour to recover from Neuromyopathy complications and prolonged hospital stay. Participants will be randomized to intervention (IG) or control group (CG)). EE therapy will be provided using a bio-electric stimulation technology (BEST) platform (Tennant Biomodulator PRO®, AVAZZIA, Inc.). The EE device will be functional for IG and non-functional for CG. In addition to taking the device home to deliver electrical stimulation themselves, the patients will attend a weekly assessment at the McNair Campus for up to 4 weeks. The primary outcomes include between group difference and change from the baseline in muscle endurance, muscle strength, lower extremity tissue oxygen saturation, neuropathy, and muscle atrophy.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Gastrocnemius Muscle Endurance (Muscle Sustained Contraction) in Response to Electrical Stimulation	Gastrocnemius muscle endurance in response to 5 minutes of electrical stimulation therapy will be assessed with surface electromyography using a validated non-invasive device (Delsys Trino Wireless EMG System, MA, US).	an average of 4 weeks (Phase II)
Primary	Ankle Strength	Ankle strength will be measured in response to the average of three 5-second dorsiflexion maximum voluntary isometric contractions per 30 seconds of relaxation in-between using a dynamometer (RoMech Digital Hanging Scale).	an average of 4 weeks (phase II).
Secondary	Plantar Oxyhemoglobin	Percentage of oxyhemoglobin (OxyHb) will be measured using a validated near-infrared (NIR) camera (Snapshot NIR, KENT Imaging Inc., Calgary, AB, Can) that detects an approximate value of real-time OxyHb level in superficial tissue. The metatarsus area including the five toes will be traced. Data reported includes plantar oxyhemoglobin after 10 minutes of stopping 1 hour of electrical stimulation therapy.	an average of 4 weeks (phase II)
