Like other tactile discrimination tests, the test for this is a measurement of the patient's sense of touch, and requires that the patient perform the test voluntarily and without visual contact. The purpose of this form of tactile discrimination is to detect any defects in the Central nervous system such as lesions in the Brainstem , Spinal ...
Romberg's test, Romberg's sign, or the Romberg maneuver is a test used in an exam of neurological function for balance. The exam is based on the premise that a person requires at least two of the three following senses to maintain balance while standing: proprioception (the ability to know one's body position in space)
The Mini-Balance Evaluation Systems Test (Mini-BESTest): Is a short form of the Balance Evaluation System Test that is used widely in both clinical practice and research. The test is used to assess balance impairments and includes 14 items of dynamic balance task, divided in to four subcomponents: anticipatory postural adjustments, reactive ...
To test for intact barognosis, a set of small objects with the same size and shape but of graduated weight is used. A series of different weights can be placed one at a time in the same hand, and the patient is asked to identify the comparative weight of the objects, i.e. by saying whether the object is "heavier" or "lighter".
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.
It makes use of the psychophysiological finding that greater muscle tone reduces proprioceptive sensitivity. [6] Kinaesthetics may benefit patients who need: Assistance in activities of daily living (ADL) Somatic feedback; To reduce the physical effort required to move
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.
The auditory system, vestibular system (within the inner ear), and proprioceptive system (sensory receptors located in the skin, muscles, tendons and joints) collectively work to coordinate movement with balance, and can also create illusory nonvisual sensations, resulting in spatial disorientation in the absence of strong visual cues.
