The piano-playing-like finger-tapping movement has been analyzed with a precision image-based motion analyzer (PRIMAS). 32 healthy subjects (148 recordings) and 10 Parkinsonian patients (25 recordings) were tested. The tracking of fingers during the whole movement increased the level of information obtained from the finger-tapping test compared to visual observation or to measurement with simpl...

With its unique structure, the Akiyama probe is a type of tuning fork atomic force microscope probe. The long, soft cantilever makes it possible to measure soft samples in tapping mode. In this article, some characteristics of the probe at its second eigenmode are revealed by use of finite element analysis (FEA) and experiments in a standard atmosphere. Although the signal-to-noise ratio in thi...

When items in a to-be-remembered list sound similar, recall performance is worse than when items are acoustically distinct, what is known as the acoustic confusion effect (ACE). When participants are asked to tap a syncopated rhythm during list presentation, the difference between the acoustically similar and dissimilar conditions is abolished; however, simple temporal and simple spatial tappin...

A human can perceive the hardness of an object by tapping its surface. We compared the ranked subjective hardness values and physical properties of objects, including their stiffness, viscosity, density, and Shore hardness, and the frequencies and time constants of the natural vibrations caused by tapping. The stiffness, frequency, and viscosity exhibited a relatively strong positive correlatio...

Many subjects in early phase clinical trials expect to benefit in some way from the research intervention. It is understandable that people hope for improvement in their condition, no matter what the evidence. Yet unreasonable expectation of medical benefit may reflect problems with informed consent: Investigators may not disclose clearly that direct medical benefit from an early phase experime...

Purpose: Given the high prevalence of varus malalignment of the knee and the consequences of walking on different surfaces on this malalignment, the aim of the present study was to investigate the effect of walking inclination on knee angle in the frontal plane of patients with varus malalignment. Methods: 18 male subjects with varus malalignment classified at grade 3 bowleg, within the a...

By Surgeon A. Toji.es, Civil Surgeon Midnapore. Apropos of the question of the advisability of puncturing the inflated intestine in obstruction or strangulation, which was raised at a recent meeting of the Calcutta Medical Society. The following notes of a case in which the procedure was completely successful may be of interest. The tapping was not limited to the tumour, it was a case of Strang...
