“…Before SCI, the contribution of these factors to force generation differs between muscles, across force levels, with different inputs, and as muscles fatigue [90][91][92][93][94]. Following SCI, other factors such as adaptation and muscle reinnervation may become important [95,96,81].…”

Abstract-This article compares some physiological methods commonly used to measure the functional capability of the motor system in humans and animals after spinal cord injury. Some of the differences between animal and human experimentation are considered first. Then we discuss how to measure the effectiveness of conduction through the motor system. We describe ways to assess the integration of different inputs at the spinal cord and to measure the responsiveness of the neuromuscular system. We conclude that comparisons across species are invaluable to understand the control of movement, both before and after injury.

“…A fundamental mechanism underlying many patterns of recruitment is the property-ranked recruitment hierarchy based on the size principle of Henneman (e.g., Henneman et al, 1965;Milner Brown et al, 1973). In many actions motor units are recruited according to their size.…”

In muscle and movement modelling it is almost invariably assumed that force actually exerted is determined by several independent factors. This review considers the fact that length force characteristics are not a relatively fixed property of muscle but should be considered the product of a substantial number of interacting factors. Level of activation and recruitment are influential factors in relation to aspects of muscle architecture. For the level of activation effects of its short term history (potentiation, fatigue in sustained contractions) have to be taken into account and are reviewed on the basis of recent experimental results as well as available literature. History is also an important determinant for the effect of length changes. This concept is introduced on the basis of recent experimental evidence as well as available literature. Regarding effects of muscle architecture, the concepts of primary and secondary distribution of fibre mean sarcomere length are introduced as well as effects of muscle geometry for mono-and bi-articular muscles on those distributions. Implications for motor control are discussed and the need for intramuscular coordination indicated.
