Clear correlations between the two can help to develop and perform corresponding functional training for children with mental retardation （MR）. OBJECTIVE： This study was designed to evaluate and analyze the correlation of fine motor function to cognitive competence in MR children using the Peabody Developmental Motor Scale-Fine Motor （PDMS-FM） and Symbolic Play Test. DESIGN： Scale evaluation and correlation analysis. SETTING： Children＇s Rehabilitation Center ＆ Huajing District Hospital, Children＇s Hospital Affiliated to Fudan University. PARTICIPANTS： A total of 42 MR children, 28 males and 14 females, aged 14-69 months, were admitted to the Rehabilitation Center, Children＇s Hospital, Fudan University between June 2003 and April 2006, and were recruited for this study. All children corresponded to MR diagnosis criteria determined by Chinese Neurology and Psychiatry Society in 1989. Written informed consent for participating in the evaluation and for evaluated content was obtained from each child＇s guardian. METHODS： Subsequent to admission and prior to treatment, fine motor function of each MR child was evaluated using PDMS-FM （Chinese version）. The scale captured 98 items that formed the grasping （Gr） and visual-motor integration （Vi） subtests. Cognitive competence was evaluated using the Symbolic Play Test （Chinese version）, which captured four 6-item specific contents. The original score of each subtest was used to evaluate results for statistical analysis. Higher scores from the two evaluations indicated stronger abilities. Pearson correlation analysis was applied for analyzing data correlation. MAIN OUTCOME MEASURES： Fine motor function was evaluated using PDMS-FM. Cognitive competence was measured using the Symbolic Play Test. Correlations between results from the two evaluations were analyzed. RESULTS： All 42 MR children were included in the final analysis. Correlation analysis results demonstrated significant positive correlations of original scores existed between Gr and Vi subtests in the PDMS-FM （r = 0.761, P 〈 0.01）, and between Vi and Gr subtests in PDMS-FM and Symbolic Play Test （r = 0.663, 0.450, P 〈 0.01）. CONCLUSION： Fine motor function closely correlates to cognitive competence in MR children. This indicates fine motor function training should be developed in combination with cognitive competence training.展开更多

However, the relationship between activated regions and motor recovery after mental practice training is not well understood. In this study, 15 patients who suffered a firstever subcortical stroke with neurological deficits affecting the right hand, but no significant cognitive impairment were recruited. 10 patients underwent mental practice combined with physical practice training, and 5 patients only underwent physical practice training. We observed brain activation regions after 4 weeks of training, and explored the correlation of activation changes with functional recovery of the affected hands. The results showed that, after 4 weeks of mental practice combined with physical training, the Fugl-Meyer assessment score for the affected right hand was significantly increased than that after 4 weeks of practice training alone. Functional MRI showed enhanced activation in the left primary somatosensory cortex, attenuated activation intensity in the right primary motor cortex, and enhanced right cerebellar activation observed during the motor imagery task using the affected right hand after mental practice training. The changes in brain cortical activity were related to functional recovery of the hand. Experimental findings indicate that cortical and cerebellar functional reorganization following mental practice contributed to the improvement of hand function.展开更多
