The aim of the research was a comparison of the data achieved by the accelerometer
and the clinical diagnosed lameness.
39 cattle in total were part of the research. 18 of them were without lameness,
15 were classified as moderately lame and 6 as high- grade lame.
The clinical evaluation of the lameness was executed by two independent investigators,
C.G. and J.K.
By means of the accelerometer were measured the acceleration in vertical (z),
longitudinal (x) and lateral direction (y) of the cattle.
Some axis intercepts were abstracted of the generated curve chart for a further
analysis. Firstly, with the help of the axis intercepts, the rate of the cycle of
movement was calculated, secondly there was generated the standard deviation
for the x-, y- and z- axis as well as the standard deviation of the value of the
vectors. The rate of the cycle of movement was related to the respective standard
deviations. For the cattle without lameness it was possible to identify that
the relation of each axis and the value of the vectors was linear. With the increasing
rate of the cycle of movement also the standard deviation for the x-, yand
z- axis and the sum of the vectors rose.
This linear relation could also be observed at the moderately lame cattle. Regarding
the high- grade lame cattle it was no more possible to identify a significant
Based on the data of the cattle without lameness were made a comparison with
the moderately lame and high- grade lame cattle.
The percentage rate of conformance between the clinical diagnose and the result
achieved by means of the accelerometer was about 74,07% at the cattle
without lameness, 73,33% at moderately lame and 88,81% at high- grade lame
