Dynamic ataxy investigation

Finger-nose probe- investigated person while his standing with closed eyes must touch nose ending by his index finger. To pay the attention to finger movement trajectory (locomotory ataxy existance) and putting to mentioned place (dysmetry existance), finger’s tremor.

Heel-knee probe- the investigated person while sitting at the chair must touch by heel of one foot the knee of another one and to draw by it through tibia down. To mention locomotor ataxy absence or presence and dysmetry from lower extremities.

Probe to adiadochokinesis- investigated person while his sitting must at the same time (simultaneously) by two hands stretched forward to perform pronation and supination. At disturbance of movement sinchronism and equality one can determine adiadochokinesis on the side where the extremity is retarded.

Probe to the movement proportionality - the investigated person must stretch his hands forward by his palms up, the fingers are diverged. At order to turn hands by their palms down. At cerebellum injury side one can determine excessive rotation - dysmetry.

To put the attention to:

1. At cerebellum injury speech is slowed, speech fluency, explosed, scanding- accents are not on necessary syllable.

2. The writing in sick people is large, uneven, the person hasn’t draw the circle.

3. There is rhythmic eyeballs fluctuation at sight towards and up - nistagm.

15. Autonomic nervous system reflexes (pupils size changes at direct light and in the darkness, reflex to eyes convergence, skin vasomotor functions, red and white dermographism, Erben’s and Abrams’ reflexes).

To perform pupils investigation

Pupils investigation better to carry out at day dispersed light of middle force. The investigated person sits on a chair with the face turned to the window, turns his head behind to the chair back and looks into ceiling (pupils are seen distinguishly). To mark pupils size and equality. To close one investigated person eye with hand (or scale) and to pay the attention to convergent size change and equality of other eye pupil, then to open it. To mark pupil reaction, to assess this reaction: alive, middle or weak.

Under norm at bright lighting the pupil is narrowed. In dark room, on the contrary, pupils are dilated. Dilated pupil’s state is called midriasis. The constant narrowing state – miosis.

Reflex to eyes convergence

To determine investigated person pulse while his sitting for 15 seconds. Then the investigated person converges eyeballs axes for 15 seconds. After this it‘s necessary to determine pulse again. To make the conclusion.

Vasomotor skin functions investigation

The investigated person rises one hand up (maximally) with divergent extensed fingers, other puts down for 30 sec. It is necessary to determine skin colour difference. Then the investigated person stretches both hands before himself for 30 seconds.

Under normal conditions hands colour must become equal in course of this time. At vegetative disfunction the skin colour leveling are retarded or becomes zyanotic for long, hand putted down or raised up becomes pale for 1 or more minutes.
