A Preliminary and Quantitative Reappraisal of the Wartenberg Test in Parkinsonian Patients
Wartenberg (1951), appreciating the need for a simple, reliable, test to examine muscle tone in rigidity or spasticity, described such a test. Basically he observed the duration and pattern of movement of the lower legs as they swung freely, after simultaneous release from the horizontal. Reintroducing this test to measure spasticity in young adults, Bajd and Vodovnik (1984) obtained quantitative data by use of electogoniometers. Their test has been evolved further, to include microcomputer analysis (see acknowledgement) of the goniometer output. We have, using these advances, reapplied the Wartenberg pendulum test to Parkinsonian patients, and present here a preliminary account of some of our findings, together with some data from both healthy age matched controls and elderly stroke patients, with and without spasticity.
