Clinic
- It is an entity which is characterized with problems in UMN Pathways
- They are first-order neurons which are responsible for carrying signals that initiate and modulate movement, in order to coordinate movement.
- The major UMN tract that initiates voluntary movement is the pyramidal tract.
- Static etiologies (like )
- Dynamic (Motor Neuron Disease)
Sign / Symptoms
- Muscle Weakness
- Decreased motor control including Speed, Accuracy and Dexterity
- Hypotonia or Hypertonia
- Decreased endurance
- Exaggerated deep tendon reflexes including:
- Spasticity
- Hyper reflexia
- Clonus (a series of involuntary rapid muscle contractions)
- Reappearance of primitive reflexes, such as the extensor plantar response (Babinski sign)
