With respect to physical therapy interventions, it has been determined that repetitive task-specific sensory input can improve motor output in patients with central cord syndrome. These activities enable the spinal cord to incorporate both supraspinal and afferent sensory information to help recover motor output. [9]
Sensory ataxia is both a symptom and a sign in neurology. It is a form of ataxia (loss of coordination ) caused not by cerebellar dysfunction but by loss of sensory input into the control of movement.
The dynamic interactions between Spinal cord and sensory input are ensured by modulating transmission in locomotor pathways in a state- and phase-dependent manner. For instance, proprioceptive inputs from extensors can, during stance, adjust the timing and amplitude of muscle activities of the limbs to the speed of locomotion but be silenced ...
The spinal cord is an estimated 45 centimetres (18 inches) long in males and about 43 cm (17 in) in females. [citation needed] It is ovoid-shaped and is enlarged in the cervical and lumbar regions. The cervical enlargement, stretching from the C4 to T1 vertebrae, is where sensory input comes from and motor output goes to the arms and trunk.
The thalamus is generally believed to relay sensory information between a variety of subcortical areas and the cerebral cortex. [4] It is known that sensory information from environmental stimuli travels to the thalamus for processing and then to the somatosensory cortex for interpretation. The final product of this communication is the ability ...
Central sensitization is when there are changes in the responsiveness of the neurons in the dorsal horn of the spinal cord, which deals with processing somatosensory information, due to increased activity from the peripheral nociceptors. Peripheral nociceptors are sensory neurons that alert us to potentially damaging stimuli. [9]
The dorsal column–medial lemniscus pathway (DCML) (also known as the posterior column-medial lemniscus pathway (PCML) is the major sensory pathway of the central nervous system that conveys sensations of fine touch, vibration, two-point discrimination, and proprioception (body position) from the skin and joints.
Central pattern generators are groups of neurons in the spinal cord that are responsible for generating stereotyped movement. It has been shown that in cats, rhythmic activation patterns are still observed following removal of sensory afferents and removal of the brain., [1] indicating that there is neural pattern generation in the spinal cord independent of descending signals from the brain ...
