About
Denise Johnson is a researcher specializing in the quantitative assessment of spasticity, particularly in individuals with acquired brain injury, stroke, and upper motor neuron syndrome. Her work focuses on developing robotic and biomechanical methods to objectively measure spasticity, moving beyond subjective clinical scales like the Modified Ashworth Scale. Johnson’s key contributions include designing robotic manipulators to analyze velocity-dependent resistance and transverse forces during passive elbow and upper limb movements. Her most cited paper, “Robotic pilot study for analysing spasticity: clinical data versus healthy controls” (2015, 25 citations), established foundational differences between spastic and healthy populations. Subsequent studies, such as her 2020 pilot comparing velocity-dependent resistance in brain injury patients to healthy controls (4 citations), advanced the integration of rehabilitation robots into clinical assessment. Johnson’s work addresses a critical gap in spasticity quantification, offering more precise, reproducible metrics for diagnosis and treatment monitoring. Her research is instrumental for clinicians and engineers developing assistive technologies, and her pilot studies provide essential benchmarks for larger clinical trials.
