Multiple Factorial Analysis of Fine Motor Skills

Analysis of the course of Parkinson's disease under dopaminergic therapy: Performance of “fast tapping” is not a suitable parameter

“…A large body of research exists that has examined the simple correlation between cross‐sectional clinical data and instrumental parameters 24–26. The more sophisticated approach to analyze internal consistency with factor analysis allows reduction of the data volume from test batteries to meaningful dimensions of motor performance in healthy controls27–30 and parkinsonian patients 31–33. In most cases, such studies involve investigation in a few parameters at most, which by no means encompass the entire spectrum of motor disturbances.…”

“…Controlled and repeated studies by Earle and Gaw (1930) (Cox, 1934) on intercorrelations of scores on different motor tests led to extraction of motor factors of speed and precision determining score variance. In his earlier studies of motor activities Seashore (1940) detected precision factor and movement coordination factor, which was followed by detection of several group and specific psychomotor factors in later analyses of relationships among different motor activities.…”

“…Studies: In order to verify H. J. Eysenck's hypotheses concerning the correlation of personality, and the way of stress coping, psychological studies were performed in 100 soldiers, aged [18][19][20][21][22][23][24][25][26]50 Study Performance The experimental group consisted of SFOR soldiers. 50 soldiers participated in the survey, 3 questionnaires however, had to be rejected as they were improperly filled in.…”

The motor abilities of speakers with good and poor articulation∗

“…3 From his own findings and those of other investigators such as Buxton, 4 Farnsworth, 5 and Perrin, 6 he concluded that there was an absence of any "general" factor of motor ability. 7 Some relationship has been found, however, between certain tests of motor ability. To explain this, Seashore has suggested that "patterns of action" are important; thus, a subject might perform a tapping action about as well with his hand as with his foot.…”
