N1 - Funding Information:
The consequence of trauma in the spinal cord is a partial or complete loss of motor, sensory and autonomic functions below the level of lesion [1]. The interruption of the spinal interneuronal circuits connecting the brainstem and the supraspinal motor center interfere with several aspects of normal gait [2]. The * This research is part of the HYPER project “Hybrid Neuroprosthetic and Neurorobotic Devices for Functional Compensation and Rehabilitation of Motor Disorders” (Ref. CSD2009-00067) funded by CONSOLIDER-INGENIO 2010, Spanish Ministry for Science and Innovation. ** Corresponding author.

N2 - Muscles synergies, or motor modules, are thought to be the building blocks of motor control in vertebrates. In human walking, experimental finding demonstrated that 4 to 5 synergies can explain most of the variability of electromyographic activity of lower limb muscles. How is modular control affected in neurologically injured patients is still object of investigation. In this paper we present preliminary experimental findings on the modular control of walking in three incomplete spinal cord injury (SCI) patients. Results show that the impulsive and synergistic control of muscles is preserved in these patients, and that the basic features are in general similar to the healthy modular control, as described in the literature. Relevant differences in timing recruitment of muscle synergies are associated to large deviations in spatiotemporal parameters, supporting the functional meaning of muscle synergies.
