An interventional study of Neuromuscular Electrical Stimulation (NMES) and High Protein Supplementation in Subarachnoid Hemorrhage, Muscle Atrophy and Inflammation, sponsored by University of Maryland, Baltimore. Recruiting at 1 site in United States. Open to participants aged 18 Years and older. Per ClinicalTrials.gov, last updated 2026-09-04.
Sponsored by University of Maryland, Baltimore · Not applicable, Interventional, and Treatment
The study purpose is to investigate the hypothesis that in adults with SAH, early neuromuscular electrical stimulation (NMES) and high protein supplementation (HPRO) will improve muscle mass, metabolic and inflammatory biomarker profiles, compared to SAH controls receiving standard of care interventions for nutrition and mobilization. The investigators will accomplish this by studying the effects of a high protein (HPRO) nutritional treatment as well as NMES intervention have upon muscle wasting and motor strength acutely after SAH. This will be addressed in a prospective trial of SAH patients receiving HRPO with NMES as compared to age and severity-matched SAH patients undergoing standard of care interventions for nutrition and mobilization. Additionally, the study will investigate the impact HPRO and NMES interventions have upon inflammatory cytokines and markers of energy balance. Results of this study will establish evidence for precision nutrition plus early exercise to mitigate the catabolic and inflammatory state produced by SAH to improve muscle, metabolic, and health recovery outcomes.

Exclusion criteria:
Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.
Weight in kilograms divided by height in metres squared. Example: 70 kg and 1.75 m gives 70 ÷ (1.75 × 1.75) ≈ 22.9.
What counts as overweight or obesity differs between countries (some use lower cut-offs), so go by the range the study states.
Malignancy means cancer. Criteria about another or earlier malignancy ask whether you have had a different cancer, usually within a set number of years.
Some are commonly allowed, such as treated skin cancers other than melanoma and early cancers removed completely — check the exceptions this study lists.
GFR (glomerular filtration rate) is how much blood the kidneys filter each minute. It is usually estimated from a blood test — eGFR, by formulas such as CKD-EPI or MDRD — and some studies ask for it to be measured directly instead. Usually given in mL/min/1.73 m².
Check the method, the units and the minimum the study states. A value of 90 or above is in the normal-or-high range, but kidney damage can show in other tests too.
Two enzymes measured in a routine blood test of the liver. Higher levels can mean the liver is under strain or damaged. SGPT and SGOT are older names for ALT and AST.
Criteria usually give a limit as a multiple of the upper limit of normal (ULN), often higher when cancer has spread to the liver.
