Pendulum test in chronic hemiplegic stroke population: additional ambulatory information beyond spasticity

Abstract Spasticity measured by manual tests, such as modified Ashworth scale (MAS), may not sufficiently reflect mobility function in stroke survivors. This study aims to identify additional ambulatory information provided by the pendulum test. Clinical assessments including Brünnstrom recovery sta...
