Noninvasive measurements are fast gaining importance in every clinical discipline. Noninvasive acceleration measurements of physiological vibrations may aid in clinical diagnosis and quantitative assessment of various diseases. In the discipline of rehabilitation medicine, Reddy et al [1–4] have developed and clinically evaluated the techniques of non-invasive quantitative assessment of the swallowing mechanism in dysphagic patients, using noninvasive measurements of acceleration at the throat. In the discipline of rheumatology, Reddy et al.[5] have used acceleration signals to distinguish osteoarthritis, rheumatoid arthritis, and chondromalacia of the knee joint. Rangayyan et al [6] have used acceleration signals from the knee joint to classify articular cartilage pathology. Reddy et al [7] have reported measurement of acceleration for differential diagnosis of spondylo-arthropathy from rheumatoid arthritis of the knee joint.
