In the Romberg test, the standing patient is asked to close their eyes. An increased loss of balance is interpreted as a positive Romberg's test. The Romberg test is a test of the body's sense of positioning (proprioception), which requires healthy functioning of the dorsal columns of the spinal cord. [1]
A 2006 study measured the P1 response in deaf children who received cochlear implants at different ages to examine the limits of plasticity in the central auditory system. [24] Children who received cochlear implant stimulation while younger than 3.5 years had normal P1 latencies. Children older than seven years had abnormal latencies.
Proprioception was then found to be involved in other tropisms and to be central also to the control of nutation. [79] The discovery of proprioception in plants has generated an interest in the popular science and generalist media. [80] [81] This is because this discovery questions a long-lasting a priori that we have on plants.
Proprioceptive feedback is also linked to motor deficits in Parkinson's disease and cerebral palsy. People with cerebral palsy often suffer from spasticity due to hyperreflexia. [13] A common clinical test of spasticity is the pendulum test, in which the subject remains seated and the relaxed leg is dropped from horizontal.
The McCarthy Scales of Children's Abilities has been used in many different research studies: ". . . use to evaluate the effects of nutritional supplements given to nursing mothers on the development of the nursing infants, the effects of air-pollution on children's cognitive developments, and the effects of early intervention on the cognitive development of preterm infants."
The dynamic visual acuity test involves a patient's ability to control eye movements by following letters that appear on a screen. The difference between these two test results is the patient's fixation ability and vestibuloocular reflex (VOR) efficiency. [13] Vestibular reflexes can also be examined using body tilt experiments.
Other sensory modalities exist, for example the vestibular sense (balance and the sense of movement) and proprioception (the sense of knowing one's position in space) Along with Time (The sense of knowing where one is in time or activities). It is important that the information of these different sensory modalities must be relatable.
Lastly, Nardini et al. (2010) recently hypothesised that young children have optimized their sensory appreciation for speed over accuracy. [98] When information is presented in two forms, children may derive an estimate from the fastest available source, subsequently ignoring the alternate, even if it contains redundant information.
