Proprioception in somatoform disorders
Section snippets
Subjects
Participants were 20 in-patients with somatoform disorders and the mean age of 46.00 years (SD=7.93) and 20 healthy controls with the mean age of 41.78 (SD=8.29). The groups did not differ in age [t(38)=1.58, n.s.]. Both groups consisted of 13 men and 7 women.
Subjects participated voluntarily and free of charge. The clinical sample was recruited in a psycho-somatic clinic with a cognitive-behavioural therapeutic background. The control subjects were asked personally to take part in the
Results
A two-tailed MANOVA (P<0.01) was calculated across the five proprioceptive parameters in order to establish whether differences occurred between somatoform patients and healthy subjects. This analysis showed no significant overall effect, F(5,34)=1.87, n.s.. Nevertheless, the corresponding univariate analysis showed some significant differences (s. Table 2). Somatoform patients exhibited higher precision than healthy subjects. Furthermore, the group difference for intensity were just short of
Discussion
The results of this study reveal three important aspects of proprioception: (1) within a univariat comparision patients with somatoform disorders show a tendency to a more intense and a more precise myogen proprioception (see Table 2). (2) The variables precision and intensity show a high sample dependent correlation within the population (see Table 3). Correlation coefficient is statistically significant for healthy people, but only by chance for somatoform patients. Although there seems to be
