The Balance Evaluation Systems Test (BESTest)
This unique clinical balance evaluation tool allows clinicians to separate balance disorders into problems with 6 different balance systems. A copy of the test with clinical examples for how to score each item is now available.
This new test allows clinicians to quantify 4 different types of balance and gait in their patients who wear small inertial sensors during testing. This instrumented test is much more sensitive, reliable and accurate than clinical rating scales or questionanaires for evaluating balance and gait disorders. Currently, we are developing mobility scores for the elderly and for people with Parkinson’s disease, testing its reliability and sensitivity to exercise supported by the Kinetics Foundation.
Audiobiofeedback for Balance Control (European Patent)
In collaboration with the U of Bologna Dept of Engineering, we developed a unique biofeedback device to improve balance by providing changes in tones related to postural sway. Our studies have shown significant improvement in quiet stance and in walking in patients who have loss of vestibular function.

Agility Exercise Program to Delay Mobility Disability in Parkinson’s Disease
We are currently testing the effectiveness of a newly designed exercise program specifically focused on improving dynamic balance in people with Parkinson’s disease. This intensive program, directed by physical therapists at OHSU, is unique in providing challenging exercises for each of the constraints on mobility from Parkinson’s disease.
