What are the building blocks with which the human spinal cord constructs the motor patterns of locomotion? In principle, they could correspond to each individual activity pattern in dozens of different muscles. Alternatively, there could exist a small set of constituent temporal components that are common to all activation patterns and reflect global kinematic goals. To address this issue, we studied patients with spinal injury trained to step on a treadmill with body weight support. Patients…

Distributed plasticity of locomotor pattern generators in spinal cord injured patients.
TLDR
Recovery of foot kinematics in SCI patients may not be subserved by changes localized to limited regions of the spinal cord, but may depend on a plastic redistribution of activity across most of the rostrocaudal extent ofThe spinal cord.
Patterned control of human locomotion
TLDR
Recent studies on human locomotion showing that muscle activity is accounted for by a combination of few basic patterns, each one timed at a different phase of the gait cycle are reviewed.
Distributed neural networks for controlling human locomotion Lessons from normal and SCI subjects
Human spinal locomotor control is based on flexibly organized burst generators.
TLDR
The data imply that the human lumbar spinal cord circuits can form burst-generating elements that flexibly combine to obtain a wide range of locomotor outputs from a constant, repetitive input.
Spinal cord maps of spatiotemporal alpha-motoneuron activation in humans walking at different speeds.
TLDR
A striking feature is that nearly every spinal segment undergoes at least two cycles of activation in the step cycle, thus supporting the idea of half-center oscillators controlling MN activation at any segmental level.
Merging of healthy motor modules predicts reduced locomotor performance and muscle coordination complexity post-stroke.
TLDR
A common modular organization of muscle coordination underlying walking in both healthy and post-stroke subjects is suggested, which may lead to new insight into impaired locomotor coordination and the underlying neural systems.
Neural regulation of rhythmic arm and leg movement is conserved across human locomotor tasks
TLDR
The results show strong correlation across tasks and support common neural patterning as the regulator of arm and leg movement during various rhythmic human movements.
Coordination of Locomotion with Voluntary Movements in Humans
TLDR
It is proposed that this superposition of an invariant locomotion timing pattern with a voluntary activation timing may be consistent with the proposal suggesting that compound movements are produced through asuperposition of motor programs.
Can modular strategies simplify neural control of multidirectional human locomotion?
TLDR
This work investigates how simple modular controllers based on invariant neural primitives (synergies or patterns) might generate muscle activity observed during multidirectional locomotion and finds that modular architectures could theoretically reduce dimensionality compared with independent muscle control.
Modulation of phasic and tonic muscle synergies with reaching direction and speed.
TLDR
It is found that the amplitude modulation of three time-invariant synergies captured the variations in the postural muscle patterns at the end of the movement, suggesting that muscle synergies are basic control modules that allow generating the appropriate muscle patterns through simple modulation and combination rules.

Level of spinal cord lesion determines locomotor activity in spinal man
TLDR
It was found that the higher the level of spinal cord lesion the more ”normal” was the locomotor pattern, suggesting that neuronal circuits underlying locomotor ”pattern generation” in man are not restricted to any specific level(s) of the spinal cord, but that an intricate neuronal network contributing to bipedal locomotion extends from thoracolumbal to cervical levels.

TLDR
A conceptual model for the human locomotor control process is proposed and some common features among the EMG patterns suggest that the nervous system does not have to generate all the muscle activity patterns, only the common features that can, in appropriate combination, produce the necessary activity patterns.
Fundamental patterns of bilateral muscle activity in human locomotion
TLDR
The application of factor analysis to the electromyographic patterns of 16 muscles in ten normal subjects suggests that the central nervous system solves the problem of high dimensionality by generating a few fundamental signals which control the major muscle groups in both legs.
Combinations of muscle synergies in the construction of a natural motor behavior
TLDR
It is shown that combinations of three time-varying muscle synergies underlie the variety of muscle patterns required to kick in different directions, that the recruitment of these synergies is related to movement kinematics, and that there are similarities among the synergies extracted from different behaviors.
Locomotor activity in spinal man: significance of afferent input from joint and load receptors.
TLDR
It can be concluded that afferent input from hip joints, in combination with that from load receptors, plays a crucial role in the generation of locomotor activity in the isolated human spinal cord.
Pattern Generators in Locomotion: Implications for Recovery of Walking After Spinal Cord Injury
TLDR
The evidence from experimental models of animals after spinal transection demonstrates that the spinal cord of at least some adult mammals can execute full weight bearing stepping independent of brain input.
Simple artificial neural network models can generate basic muscle activity patterns for human locomotion at different speeds
TLDR
A network with a relatively small number of hidden units trained with back-propagation was able to produce an excellent representation of both the amplitude and timing characteristics of the EMGs over a range of walking speeds.
Tapping into spinal circuits to restore motor function
Kinematic determinants of human locomotion.
TLDR
The aim of this study was to find kinematic patterns that are invariant across the normal range of locomotion speeds, and found waveforms of global length and elevation of the limb, elevation angles of all limb segments and flexion‐extension at the knee were invariant with speed.
Computations underlying the execution of movement: a biological perspective.
TLDR
Some of the mechanisms and circuitry underlying the transformation of motor plans into motor commands are described and a central feature of this transformation is a coarse map of limb postures in the premotor areas of the spinal cord.
