Because both PD and VP show postural reflex disturbances, small-stepped gait and little kick-off power on walking may represent acquired gait pattern for defensive posture and prevention of falling.

The development of the pups' motor activity may be evaluated by postural reflex. When testing this reflex, the offspring of the rats in Group 3 responded faster than those in Group 2, or rather, their postural reflex was 46.7% more developed when compared to that of Group 2 pups, albeit with no statistical difference.

Oppositely, oscillations <0.6 Hz are related to a slow center of mass (COM) drift rather than to postural reflexes. When compared to fluctuations at higher frequency range, these fluctuations are often of higher amplitude and because of it, they mask proper reflexes of the posture control.
The filtering of the posturographic signals shows the age related features
"It interrupts the postural reflexes that are key to maintaining balance so a patient can't make the corrections necessary to prevent a fall," Dr.

Loss of postural reflexes leads to backward falls (retropulsion) or forward falls (propulsion) without cause.
Parkinson's disease: early diagnosis and management
It is assumed that, in PD patients, reaching movement is limited by decreased movement of the upper limbs due to akinesia or bradykinesia, decreased flexibility due to rigidity of the four limbs and trunk, and the impairment of postural reflexes associated with these decreases.
The cognition of maximal reach distance in Parkinson's disease
PD is characterized by resting tremors, bradykinesia (slowness of voluntary movement), rigidity, and a loss of postural reflexes. Patients with PD typically have a flat, expressionless face and walk with a stooped gait characterized by small steps.
