Muscle Wasting in the Critically Ill

Muscle Weakness Clinical Trial

Official title: Effect of Early Rehabilitation Using an Active/Passive Cycling Device on Muscle Wasting in the Critically Ill: A Randomised Controlled Study

Status Completed

Clinical Trial Summary

Muscle wasting is a common consequence of critical illness, and has a profound impact upon the rehabilitation of those who survive admission to critical to care. The investigators intend to assess if the application of 10 sessions over two weeks of passive cycling with electrical stimulation to the lower limbs and abdomen can prevent muscle loss, or at least cause less muscle loss, compared to patients who receive standard daily sessions of physiotherapy. This will be done by comparing the changes in muscle size on ultrasound between the two groups, comparing functional measures at a 3 month follow up, and by performing translational research using tissue samples taken during the study.

Clinical Trial Description

Patients are mechanically ventilated and sedated with a diagnosis of sepsis (from any source) will be eligible for this study. Provided they meet the inclusion criteria, they will be randomised within 48 hours of admission, to either ten 30 minute sessions of passive cycling with functional electrical stimulation (FES) to the thighs, hamstrings, calves and abdomen over a 14 day period, or to a control group of routine physiotherapy. The trial group will also receive this physiotherapy. On admission to the study, all patients will receive on day 1: Ultrasound measurements of: Rectus femoris cross-sectional area Thickness of rectus femoris and vastus intermedius Thickness, pennation angle and derived fascicle length of vastus lateralis and medial head of gastrocnemius Thickness of rectus abdominis. Thickness of diaphragm A blood sample taken from an arterial line A urine sample taken from a urinary catheter A muscle biopsy taken from the right vastus lateralis They will then receive ten 30 minute sessions of passive cycling with functional electrical stimulation over 14 days, or a control group will receive routine physiotherapy during this period. Repeat ultrasounds will be taken at days 3, 5, 7, 10 and 14. Repeat blood and urine sampling at days 5, 10 and 14. Repeat muscle biopsy at day 14. All cycling, ultrasounds and tissue sampling will end on day 14 regardless of the ventilator status of the patient. In patients who survive to be discharged from critical care, they will be followed up at 3 months for: Repeat ultrasound scan of all muscles listed Six minute walk test Hand grip and lower limb dynamometry, Balance testing (by standing upright on a pressure plate for 20 seconds) Psychological assessment using the 36 item Short Form (SF-36) questionnaire Tissue sampling will be stored in the University of Liverpool for analysis of biomarkers of muscle damage and loss between the two groups. ;
