Facial synkinesis is a common sequela to Idiopathic Facial Nerve Paralysis, also called Bell's Palsy or Facial Palsy. [2] Bell's Palsy, which is thought to occur due to a viral reactivation which can lead (through unknown mechanisms) to diffuse axon demyelination and degeneration of the seventh cranial nerve, results in a hemifacial paralysis due to non-functionality of the nerve.
Marcus Gunn phenomenon is an autosomal dominant condition with incomplete penetrance, in which nursing infants will have rhythmic upward jerking of their upper eyelid.This condition is characterized as a synkinesis: when two or more muscles that are independently innervated have either simultaneous or coordinated movements.
The central pattern generator (CPG) from the model is simulated as a network of spinal neurons that controls the basic locomotor output. [8] An effective locomotion of the model must involve a flexible coordination of spinal cord neuronal networks, thus allowing various gait patterns and independent use of the limbs.
Neurological soft signs (NSS) are a group of minor non-focal neurological signs that include synkinesis. [3] Other soft signs including clumsiness, and loss of fine motor movement are also commonly found in schizophrenia. [4] NSS likely reflect impairments in sensory integration, motor coordination, and the carrying out of complex motor tasks. [3]
The limb is organized into three regions: stylopod, zeugopod, and autopod (in order from proximal to distal). The zeugopod and the autopod contain a number of periodic and quasi-periodic pattern motifs. The zeugopod consists of two parallel elements along the anteroposterior axis and the autopod contains three to five (in most cases) elements ...
Lower limb. Foot. Cutaneous innervation of the lower limbs is the nerve supply to areas of the skin of the lower limbs (including the feet) which are supplied by specific cutaneous nerves. Modern texts are in agreement about which areas of the skin are served by which nerves, but there are minor variations in some of the details.
[citation needed] The most common form of synkinesis for Ramsay Hunt Syndrome patients involves the eye being connected to the mouth (i.e. blinking while speaking, tearing while eating) and chin dimpling (chin dimples forming when speaking). Many forms of synkinesis can be managed with use of medical Botox administered by a qualified doctor. [10]
A woman exercising. In physiology, motor coordination is the orchestrated movement of multiple body parts as required to accomplish intended actions, like walking.This coordination is achieved by adjusting kinematic and kinetic parameters associated with each body part involved in the intended movement.
