Final answer:

Yes, upper motoneuron lesions do present with clasp knife spasticity.

Step-by-step explanation:

Yes, upper motoneuron lesions do present with clasp knife spasticity.

A clasp-knife response occurs when a patient initially resists movement, but then releases, and the joint quickly flexes like a pocket knife closing. This response is indicative of a damage to the upper motor neurons. Other signs of upper motor neuron (UMN) lesions include muscle weakness, strong deep tendon reflexes, decreased control of movement, pronator drift, and a positive Babinski sign.

Examples of conditions that may result in UMN lesions include cerebral palsy, multiple sclerosis (MS), or stroke.
