5.4.3. Working up of the results

The order of working up of the results is illustrated on the example of one of the examinee’s movement coordination diagnostics report (table 16).

Calculate the absolute mistakes, which the examinee makes when performing his tasks (movements) using his left hand. In order to make this you should compare the expansion of each performed movement (see column 3) with the expansion of the appropriate given movement (see column 2).

5.4.3.2. As the beginning of the following movement coincides with the termination of the previous one you should compare the indexes of the beginning and the end of this movement with each other. So, the beginning of the first movement made by left hand is the mark “ 0 ”, and its end – “ 64 » that is why its expansion is 64 divisions (64 – 0 = 64).

The second movement starts from the mark “64” and finishes at the mark “45”. Its expansion is 19 divisions (64-45=19).

The third movement starts from the mark “45” and finishes at the mark “88”. Its expansion is 43 divisions (88-45=43) and so on.

5.4.3.3. Compare the received figures of movement expansions with the figures of given movements and put the difference down into column 5 of table 16.

So, the difference (mistake) between the first movement expansion and the first task is six divisions (70-64=6).

The second movement mistake – 30 - 19 = 11.

The third movement mistake – 43 – 40 = 3, etc.

5.4.3.4. By analogy with items 5.4.3.1 – 5.4.3.3 calculate the absolute mistakes of movements performed by right hand. Put down the results into column 6 of table 16.

5.4.3.5. Then calculate each relative mistake (B) using the following formula:

A

B = ------- x 100% (18),

GM

Where: A – absolute mistake,

GM – given movement.

5.4.3.6. You should put down the relative mistakes, made by left hand, into column 7 and the ones made by right hand – into column 8 of table 16.

5.4.3.7. Then calculate the integral relative mistake for each procedure by way of dividing the sums of right hand and left hand relative mistakes. The results should be put down into column 9 of table 16.

5.4.3.8. Calculate the “jumping out” values (they are underlined in table 16) for each of the columns 7, 8 and 9 and eliminate them from further calculations.

5.4.3.9. Then calculate the arithmetic mean values of mistakes for each of the columns 7, 8 and 9 (see the third line of table 16 from the bottom).

5.4.3.10. Calculate the arithmetic mean values of relative mistakes separately at bringing the romper-suits together and parting them according to columns 7, 8 and 9 (see the last two lines of table 16). The arithmetic mean mistake at bringing the romper-suits together is calculated according to the results of procedures 1, 3, 5, 7 and 9 and the arithmetic mean mistake at parting the romper-suits is calculated according to the results of procedures 2, 4, 6, 8 and 10.

5.4.4. The interpretation of results

5.4.4.1. The general index of coordination between the left and right hands (finiteness) is a quantity inversely proportional to the arithmetic mean value of general integrated mistake (see the third index from the bottom in column 9 of table 16).

It is a general index of sensor-motor and inter-muscular coordination. Because, on the other hand, the examinee coordinates his movements basing on visual memory representations and, on the other hand, - on the information which he receives from the muscles of his left and right hands simultaneously.

5.4.4.2. The differentiated indexes of inter-muscular coordination of finiteness are the arithmetic mean mistakes made in the process of bringing the romper-suits together and parting them (see the last two indexes of column 9 of table 16). Besides, the mistakes made in the process of bringing the romper-suits together testify to the coordination of muscles-flexion of different finiteness with each other and the mistakes made in the process of parting – to the coordination of muscles-extensors with each other.

A smaller mistake made in the process of bringing the romper-suits together (12,5%) in comparison with the mistake made at parting (15,4%) tells that the given examinee has a better coordination of flexile muscles than the extensors (it is characteristic of most people).

5.4.4.3. The arithmetic mean relative mistake of left (column 7) and right (column 8) hand tells about the inter-muscular coordination of the corresponding hand.

In our example (Table 16) the left hand has an advantage at inter-muscular coordination, because its mistake is less than that made by right hand (13,9% and 16,1% accordingly). This is characteristic of left-handed people.

5.4.4.4. The arithmetic mean mistakes made in the process of bringing the romper-suits together and parting them by left and right hands separately (columns 7 and 8 of table 16) differentiate the index of inter-muscular coordination due to the groups of muscles – flexion and extensors of each hand.

5.4.4.5. When putting the diagnosis concerning the motive coordination you should take into account the results of the investigation of movement reproduction accuracy and movement differentiation accuracy (see § 1 and § 3 of this chapter), because the above-mentioned parameters are the constituents of coordination structure and they help to supplement the diagnosis with the representations concerning the movement coordination of different value.
