The primary aim of the study was to investigate how a clinical decision process based on the International Classification of Function, Disability and Health (ICF) and the Hypothesis-Oriented Algorithm for Clinicians (HOAC-II) can contribute to a reliable identification of main problems in ambulant children with cerebral palsy (CP). As a secondary aim, to… (More)
OBJECTIVE To investigate the agreement between live and video scores of the Gross Motor Function Measure-88. DESIGN Reliability study. SUBJECTS Forty children with bilateral spastic cerebral palsy. INTERVENTIONS Fifty evaluations were administered according to the test guidelines, and were videotaped. After a minimum interval of one month, the video… (More)
We extend the analysis of a thermal Brownian motor reported by Van den Broeck [Phys. Rev. Lett. 93, 090601 (2004)] to a three-dimensional configuration. We calculate the friction coefficient, diffusion coefficient, and drift velocity as functions of shape and present estimates based on physically realistic parameter values.
Recently, a thermal Brownian motor was introduced (Van den Broeck et al 2004 Phys. Rev. Lett. 93 090601), for which an exact microscopic analysis is possible. The purpose of this paper is to review some further properties of this construction, and to discuss in particular specific issues including the relation with macroscopic response and the efficiency at… (More)
