BACKGROUND: @entity1643 ( @entity1643 ) is often accompanied by an abnormal motor performance. However, it has not been clarified yet whether these deviations also occur during motor tasks not involving the back and whether the performance is influenced by @entity158 and @entity158 . Therefore, the aim of the present study is to get insight in the contribution of both @entity158 experience and @entity158 to general motor task performance in @entity1643 . METHODS: 13 @entity1643 @entity1 and 15 healthy subjects performed a hand-function task in three conditions: sitting, lying prone (lying) and lying prone without trunk support (provoking). The last condition was assumed to provoke @entity158 , which was considered successful when a @entity1 ' @entity158 expectancy on a numeric rating scale was at least 1 point higher than actual @entity158 experienced. Subjects' performance was expressed in reaction time and movement time. Repeated measures analysis of variance was performed to detect main effect for group and condition. Special interest was given to group*condition interaction, since significant interaction would indicate that @entity1 and healthy subjects performed differently throughout the three conditions. RESULTS: @entity1 were slower throughout all conditions compared to healthy subjects. With respect to the provoking condition, @entity1 showed deteriorated performance compared to lying while healthy subjects' performance remained equal between these two conditions. Further analysis of @entity1 ' data showed that provocation was successful in 54% of the @entity1 . Especially this group showed deteriorated performance in the provoking condition. CONCLUSION: It can be concluded that @entity1643 @entity1 in general have worse motor task performance compared to healthy subjects and that provoking @entity158 further worsened performance.

Motor performance in XXXX : is there an influence of @entity158 ? A pilot study.
