Time series analysis of leg movements during freezing of gait in Parkinson's disease: akinesia, rhyme or reason?

Hausdorff, Jeffrey M; Balash, Y; Giladi, Nir - In: Physica A: Statistical Mechanics and its Applications 321 (2003) 3, pp. 565-570

We quantitatively characterized the fluctuations in the forces under the feet during freezing of gait (FOG) in 11 patients with advanced Parkinson's disease. FOG, a leading cause of falls and impaired functional independence, is a poorly understood debilitating phenomenon that is common among...

Possible determinism and the real world data

Przyborski, Marek - In: Physica A: Statistical Mechanics and its Applications 309 (2002) 3, pp. 297-303

The unique vibrations of the ship's hull are the characteristic feature of each type of the ship. The question is—Does the distribution of those vibrations consist of deterministic elements or not? We present results of testing the hypothesis that those data can be well described by the...
