Clinical Features and Impact of Spasticity

Q15. What are the various clinical features of spasticity?
*See figure 9a, 9b and 9c for reflexes post SCI
1. Velocity dependent increase in tonic stretch reflexes
2. Increased tendon jerks
3. Upper motor neuron syndrome
4. Clonus
5. Spasms
6. Hyperreflexia
7. Hypertonia

Figure 9a. Phasic stretch reflex. This picture shows reflex pathways that may underlie hyperactive phasic stretch reflexes of spasticity.

Figure 9b. Tonic stretch reflex arc. This picture shows reflex pathways that may underlie hyperactive tonic stretch reflexes of spasticity.

Figure 9c. Cutaneomuscular (flexor withdrawal) reflex. This picture shows reflex pathways that may underlie the hyperactive cutaneomuscular reflex of spasticity.
