This study aims to evaluate the performance of the TetraGraph on two muscle groups: the adductor pollicis and the abductor digiti minimi. Theese muscles are located on the arms. Key time points for assessment will include the onset of neuromuscular blockade and the recovery from rocuronium blockade using sugammadex.

Patients willing to participate and provide an informed consent
Patients undergoing elective surgical procedures that require use of NMBA agents (rocuronium) administered intraoperatively.
Patients with disorders, such as stroke, carpal tunnel syndrome, broken wrist with nerve damage, Dupuytren contracture, or any similar wrist injury.
Patients with systemic neuromuscular diseases such as myasthenia gravis.
Patients with significant organ dysfunction that can significantly affect pharmacokinetics of neuromuscular blocking and reversal agents, i.e., severe renal impairment or end-stage liver disease.
Patients having surgery that would involve prepping the arm into the sterile field.
