Lower-Limb Myoelectric Calibration Postures for Transtibial Prostheses

Lower-Limb Myoelectric Calibration Postures for Transtibial Prostheses 150 150 Transactions on Neural Systems and Rehabilitation Engineering (TNSRE)
The use of an agonist-antagonist muscle pair for myoelectric control of a transtibial prosthesis requires normalizing the myoelectric signals and identifying their co-contraction signature. Extensive literature has explored the relationship… read more

An OpenSim-Based Closed-Loop Biomechanical Wrist Model for Subject-Specific Pathological Tremor Simulation

An OpenSim-Based Closed-Loop Biomechanical Wrist Model for Subject-Specific Pathological Tremor Simulation 150 150 Transactions on Neural Systems and Rehabilitation Engineering (TNSRE)
Objective: A pathological tremor (PT) is an involuntary rhythmic movement of varying frequency and amplitude that affects voluntary motion, thus compromising individuals’ independence. A comprehensive model incorporating PT’s physiological and… read more
