A Dpr reflex, also known as the delayed plantar reflex (DPR), is an abnormal variation of the plantar reflex that requires a strong stimulus on the sole of the foot.
Here's a more detailed explanation:
- Definition: The delayed plantar reflex (DPR) is a pathologic flexor variant.
- Stimulus: It's elicited by unusually strong stimulation of the sole of the foot.
- Response Characteristics:
- Prolonged interval between stimulus and response.
- Slow and protracted plantarflexion of the great toe and/or other toes.
- Slow return to the neutral position.
In essence, the DPR is identified by the intensity of stimulation required to trigger the reflex and the slow, drawn-out nature of the toe movement.
