Stroke, Spasticity, Pendulum Test, Patellar Tendon Tap Test, Modified Ashworth Scale


Spasticity is characterized by hyperexcitable stretch reflexes with amplitude increases in response to velocity dependent passive movement and resistance. Spasticity is the result of abnormal function of segmental and suprasegmental neuronal circuits. The objective of this study was to determine any positive correlation between three clinical evaluators of spasticity (i.e., the pendulum test, the patellar tendon tap test (PTT), and the Modified Ashworth scale) in their reliability to assess spasticity in people post-stroke. It was hypothesized that the use of force movement sensors along with surface electromyography increases the reliability of the standardized clinical tests. The results show that all three clinical tests detected spasticity. However, the pendulum and the patella tendon tap tests were more reliable and sensitive than the Modified Ashworth scale in detecting the varying levels of spasticity in post-stroke subjects. These tests should be used in the clinical setting along with force-movement sensors in order to measure spasticity more accurately.
