Abstract

Bedsores are caused by prolonged pressure of soft tissues. Prevention is now better established. Better adapted mattresses should be used systematically. High fever and denutrition should be especially watched. Correct medical treatment has to provide faster cicatrisation if the pressure sore unfortunately occurs. Surgical treatment by muscular flaps has now really good results but costs a lot more in management of occasional or chronic bedridden patients.

Dynamics of effortful touch and interlimb coordination.

In biological movement systems, the level of muscular-articular links is responsible for assembling highly reliable, stable, and reproducible coordination patterns involving very many joints and muscles. Research shows that the important perceptual capabilities of this level arise from the bulk sensitivity of muscles and tendons, so-called effortful or dynamic touch, to the quantities of rotational dynamics that remain invariant (such as the inertia tensor) over variations in rotational forces and motions. The power laws characterizing this sensitivity point to underlying fractal (self-similar) processes. Other research shows that the hallmark ability of this level to produce repetitive interlimb coordinations can be addressed through a dynamics of coordination in which equations express the time-evolution of collective neuromuscular states. This research also suggests that the assembled rhythms exploit the unique blend of stability and variability characteristic of low-dimensional chaotic motion on strange attractors. In overview, research into the capabilities of the level of muscular-articular links highlights the importance of applying classical and modern (nonlinear) dynamics to understanding the assembly and perceptual control of biological movements.

Task-dependent reduction of the number of degrees of freedom in sensorimotor systems.

In this paper we present a concise review of experiments on sensorimotor performance in man from the perspective of new opportunities provided by research in microgravity, which will contribute to our basic understanding of sensorimotor processes. In particular, we will discuss some new results on strategies for dealing with the large number of degrees of freedom in biological limbs with special emphasis on human motor control and on the specific role for mono- and bi-articular muscles. Finally, we propose some ideas for future experiments on motor function in microgravity, which will reveal new basic knowledge about the role of the CNS in motor control and which will contribute to a better performance of man in sensorimotor tasks in microgravity conditions.
