Hemodynamic changes during ankle range of motion in spastic versus non-spastic calf muscles assessed using near-infrared spectroscopy (Conference Presentation)

Paper Abstract

Using portable near-infrared spectroscopy (NIRS), we characterized lower limb spastic vs. non-spastic muscle hemodynamic responses to the Modified Ashworth Scale (MAS; functional spasticity scale) and passive ankle range-of-motion (ROM) tests. This 12-wk observational study in an out-patient spasticity clinic had baseline, ~6-wk, and ~12-wk time points. Within-individual (contralateral control) and between-group (patient vs. control) measurements were compared. Spastic hemodynamic responses to MAS and ROM assessments were irregular and highly variable. Non-spastic hemodynamic changes followed three clear, repeatable patterns. NIRS may be useful in developing a hemodynamic/metabolic spasticity index.
