Psychomotor profile of elderly with Intellectual Disabilities: a comparison study with typical elders and with Alzheimer Disease


People with intellectual disability (ID) are living longer, creating new challenges in rehabilitation services. With a longer longevity, the risk of dementia is expected to increase also within this emerging group. The ageing process of persons with ID and the best program planning is a quite recent area of research and in psychomotor field there is a major need to better understand this process. This study aims to evaluate and analyze the psychomotor competences of elderly with Intellectual Disability (ID) through a comparison study with typical peers and elders with Alzheimer Disease (AD). The Portuguese version of Éxamen Geronto-Psychomoteur (EGP) was applied to 118 participants, between 45 and 94 (67.68±13.09) years-old, divided in three groups: 39 typical elders, 41 elderly with AD and 38 individuals with ID. Findings showed significant differences in psychomotor domains between participants with ID and typical peers, except in Balance and Fine Motor Skills of Lower Limbs. There were no statistically differences between participants with ID and AD in Static Balance II, Fine Motor Skills of Upper Limbs, Praxis, Knowledge of Body Parts, Vigilance, Perceptive Memory, Communication, Spatial and Temporal Domains. Elders with ID tend to present the lowest results in most domains. The identification of a psychomotor profile as well the relative role of ID and a comorbid disorder (e.g.: dementia) will contribute to more adequate decisions regarding proper services and interventions strategies.

Construct validity of The Democritos Movement Screening Tool for preschool children: an examination of the known groups’ criterion


The aim of the present study was to examine the construct validity of the DEMOST-PRE©, using the criterion of the known groups. For that purpose, the performance of 18 children with autism spectrum disorders (ASD), aged 48-72 months (M=66.6, SD=8.05 months) and 12 with intellectual disabilities (ID) (M=62, SD=9.42 months) on the nine items of the DEMOST-PRE© was compared to that of 18 typically developing peers (TD) (M=64.9, SD=8.74 months). According to the results, TD children demonstrated significantly higher scores than both the ASD and ID groups of children in all test items except the ‘overhead toss to a specific target’ (F2,45= 2,659, p =.081), while the performances of ASD and ID groups were similar. The current findings provide support for the construct validity of the DEMOST-PRE© indicating that it can serve as a valuable tool for preschool aged children.
