UMN

UPPER MOTOR NEURON DISORDERS (UMN)

An upper motor neuron starts in the motor cortex of the brain and terminates within the medulla (another part of the brain) or within the spinal cord. So, an UMN disorder would include injury, disease or disturbance within this pathway from or within the brain and to the spinal cord (Photo 6). Some examples of diagnoses of UMN disorders are: Spinal Cord Injury, Multiple Sclerosis, Stroke and Primary Muscle Disease. UMN disorders involve various degrees of spasticity and synergy patterns. The synergistic pattern will be an extensor or flexor synergy pattern.
