Age Is a Greater Influence on Small Saccades Than Target Size in Normal Subjects on the Horizontal Video Head Impulse Test
Conclusion: While this study suggests that target size may have a statistically significant impact on the vHIT saccade profile of normal subjects, age has a greater influence on the incidence and size of small vHIT saccades. Introduction The video head impulse test (vHIT) is a quantitative adaptation of the clinical head impulse test (1), and enables functional assessment of the high-frequency angular vestibulo-ocular reflex (VOR) in all three planes of head rotation (2, 3). Lightweight goggles worn by the subject detect head movement using an accelerometer and gyroscope, and a high frame rate video camera tracks eye...

Experience Journal: Growing up with cerebral palsy
Cerebral palsy (CP) is the most common physical disability of childhood. The term CP is an umbrella term for a group of disorders that affect body movement and posture as a result of damage to a baby’s developing brain. There are many causes for CP, but all occur either during pregnancy, birth or shortly after birth. Common causes include differences in brain development, infection or stroke. Oxygen deprivation is accountable for only a small percentage of cases of CP; often, the cause is unknown. Although CP is a lifelong condition that can’t be reversed, children with the diagnosis can lead rich, fulfilling lives wit...
