Reaching toward quantitative metrics of spasticity

We developed a platform for quantifying movement smoothnes relating to spasticity: the Transient Accelerative Measurement Interface (TAMI). Repetitive elbow flexions of controls and persons with stroke or cerebral palsy were recorded, while their arms were supported in a manipulandum. Results showed that: (1) impairments related to spasticity can be quantified using phase plane analysis and (2) TAMI may offer clinical benefits by delivering targeted therapies to clients subjects in a real-time format, with simple metrics that can be easily interpreted.
