To date, clinical assessment remains the gold standard in the diagnosis of Parkinson's disease (PD). We sought to identify simple characteristics of handwriting which could accurately differentiate PD patients from healthy controls. Twenty PD patients and 20 matched controls wrote their name and copied an address on a paper affixed to a digitizer. Mean pressure and mean velocity was measured for the entire task and the spatial and temporal characteristics were measured for each stroke. Results of the MANOVAs for the temporal, spatial, and pressure measures (stroke length, width, and height; mean pressure; mean time per stroke; mean velocity), for both the name writing and address copying tasks, showed significant group effects (F(6,32) = 6.72, p < 0.001; F(6,31) = 14.77, p < 0.001, respectively). A discriminant analysis was performed for the two tasks. One discriminant function was found for the group classification of all participants (Wilks' Lambda = 0.305, p < 0.001). Based on this function, 97.5% of participants were correctly classified (100% of the controls and 95% of PD patients). A Kappa value of 0.947 (p < 0.001) was calculated, demonstrating that the group classification did not occur by chance. In this pilot study we identified two simple short and routine writing tasks which differentiate PD patients from healthy controls. These writing tasks have future potential as cost-effective, fast and reliable biomarkers for PD.

These research findings contribute to our theoretical knowledge in rehabilitation and promote adopting this approach for rehabilitation of adolescents with TBI.

AimThe aim of this study was to assess awareness of performance and performance accuracy for a task that requires executive functions (EF), among healthy adolescents and to compare their performance to their parent’s ratings.MethodParticipants: 109 healthy adolescents (mean age 15.2 ± 1.86 years) completed the Weekly Calendar Planning Activity (WCPA). The discrepancy between self-estimated and actual performance was used to measure the level of awareness. The participants were divided into high and low accuracy groups according to the WCPA accuracy median score. The participants were also divided into high and low awareness groups. A comparison was conducted between groups using WCPA performance and parent ratings on the Behavior Rating Inventory of Executive Function (BRIEF).ResultsHigher awareness was associated with better EF performance. Participants with high accuracy scores were more likely to show high awareness of performance as compared to participants with low accuracy scores. The high accuracy group had better parental ratings of EF, higher efficiency, followed more rules, and were more aware of their WCPA performance.ConclusionOur results highlight the important contribution that self-awareness of performance may have on the individual’s function. Assessing the level of awareness and providing metacognitive training techniques for those adolescents who are less aware, could support their performance.

With the implementation of this programme, the occupational therapy department of the University of Haifa has created greater accessibility of the profession to both the occupational therapy providers and the recipients of occupational therapy intervention as well as serve as a model for other communities.

Studies have characterised relationships between cognitive status and a variety of clinical epilepsy factors. The aim of this study was to describe a new approach for assessing executive functions in everyday life and its unique expression in adolescents with Genetic Generalised Epilepsies (GGEs) compared with typical peers. Twenty adolescents with a diagnosis of GGEs and 20 typical healthy peers, matched by age and gender, were studied. Assessment of everyday executive function was carried out using: (1) the Weekly Calendar Planning Activity (WCPA), a direct performance based and outcome measure of strategy use and cognitive performance; and (2) Behavior Rating Inventory of Executive Function (BRIEF) parental report. Adolescents with GGEs demonstrated significantly less accuracy, less efficiency and fewer strategies used, as measured by the WCPA. Parents of adolescents with GGEs rated their child's daily performance as less efficient compared with typical peers. Better ratings of executive function (low BRIEF score) were associated with greater WCPA accuracy in the entered appointments. The WCPA provides a useful evaluation of cognitive performance for adolescents with GGEs and a functionally relevant information on task efficiency, self-monitoring and effective strategy use. Direct observation of performance supplements parental ratings and has strong potential to guide intervention and measure outcomes.
