Early and intensive Motor Training for people with spinal cord injuries (the SCI-MT Trial): description of the intervention.

STUDY DESIGN: Descriptive. OBJECTIVES: The primary objective is to describe the intervention that will be provided in a large multi-centre randomised controlled trial titled: Early and Intensive Motor Training for people with Spinal Cord Injuries (the SCI-MT Trial). The secondary objective is to describe the strategies that will be used to operationalise and standardise the Motor Training provided to participants while keeping the intervention person-centred. METHODS: The paper focuses on the rationale and principles of Motor Training for people with spinal cord injuries (SCI). The description of the intervention is based on the Template for Intervention Description and Replication (TIDieR) checklist. Specifically, it addresses the following 6 criteria of the TIDieR checklist: why the effectiveness of Motor Training is being examined; what, how, where and when the Motor Training will be administered; and how much Motor Training will be provided. RESULTS: A detailed intervention manual has been developed to help standardise the delivery of the intervention. CONCLUSIONS: This paper describes the details of a complex intervention administered as part of a large randomised controlled trial. It will facilitate the subsequent interpretation of the trial results and enable the intervention to be reproduced in clinical practice and future trials.

Anomalous ground state of the electrons in nanoconfined water.

Water confined on the scale of 20 Å, is known to have different transport and thermodynamic properties from that of bulk water, and the proton momentum distribution has recently been shown to have qualitatively different properties from that exhibited in bulk water. The electronic ground state of nanoconfined water must be responsible for these anomalies but has so far not been investigated. We show here for the first time, using x-ray Compton scattering and a computational model, that the ground state configuration of the valence electrons in a particular nanoconfined water system, Nafion, is so different from that of bulk water that the weakly electrostatically interacting molecule model of water is clearly inapplicable. We argue that this is a generic property of nanoconfinement. The present results demonstrate that the electrons, and hence the protons as well, of nanoconfined water are in a distinctly different quantum state from that of bulk water. Biological cell function must make use of the properties of this state and cannot be expected to be described correctly by empirical models based on the weakly interacting molecules model.

Variational methods for the solution of the Ornstein-Zernicke equation in inhomogeneous systems.

We show that the Ornstein-Zernicke equation and other equations of similar form obey a variational principle that can be used to derive approximate solutions. This method requires the use of an initial trial solution where the variational solution possesses a stationary "point" with respect to the trial solution when the latter is equal to the exact solution. We show that with even a very simple form of the trial solution the results are quite reasonable. Furthermore, we have demonstrated that by combining the variational method with an iterative expansion of the Ornstein-Zernicke equation it is possible to develop a self-consistent method of writing the direct correlation function.
