Spinal cord injuries must be treated as soon as possible. Studies of NASCIS protocols have questioned the use of methylprednisolone therapy. This study aimed to evaluate the effect of local delivery of methylprednisolone succinate in combination with a tri-block copolymer in rats with spinal cord injury. The experiments were conducted in accordance with the bioethical guidelines. We evaluated the state of the motor centers below the level of injury by assessing the amplitude of evoked motor responses in the hind limb muscles of rats during epidural stimulation. Kinematic analysis was performed to examine the stepping cycle in each rat. Trajectories of foot movements were plotted to determine the range of limb motion, maximum foot lift height, and lateral deviation of the foot in rats on the 21st day after spinal cord injury. We have shown that the local application of methylprednisolone succinate in combination with block copolymer leads to recovery of center excitability by 21 days after injury. In rats, they recovered weight-supported locomotion, directional control of walking, and balance. The proposed assessment method provides valuable information on gait disturbances following injury and can be utilized to evaluate the quality of therapeutic interventions.

Autism, or autism spectrum disorder (ASD), is a multifactorial disease that is characterized not only by disorders of the psycho-emotional state and social interaction, but also by somatic dysfunctions. A number of studies have also reported changes in the musculoskeletal system in patients with ASD. In this work, by the method of video analysis of movements, we demonstrated a decrease in horizontal and vertical motor activity, in addition, deviant movements were recorded, which indicates a violation in locomotor activity and increased anxiety in rats with a valproate model of autism. However, a mechano-myographic study did not reveal significant changes in the contractility parameters of isolated skeletal muscles of rats with the ASD model. Thus, it can be concluded that general differences in movement may be an independent factor in the diagnosis of autism. A more thorough study using a larger sample and detailed kinematic analysis can help in further assessing the variability of motor functions as a potential diagnostic and prognostic marker of ASD.
