Quantitative motor assessment in amyotrophic lateral sclerosis

Abstract

Reliable measurements are needed to document the natural history of ALS and to determine therapeutic efficacy. We have devised a standardized protocol that generates interval data sensitive to change-the Tufts Quantitative Neuromuscular Exam (TQNE). The TQNE consists of the following four major categories: pulmonary function, oropharyngeal function, timed functional activities, and isometric strength using an electronic strain gauge. The 29-item exam takes about 1 hour to administer and has excellent test-retest reliability.
