title: [The aged and the test of folding a rhombus Psychometric and chronopsychological aspects].
abstract: This study highlights the incongruence of geriatric institutions to set up activities for elderly people without taking into account the circadian fluctuations of cognitive processes related to circadian rhythms. By example, rehabilitation for falls is based on the indication given by the therapist (instruction), its integration and assimilation by the patient (comprehension), and the resulting action (execution). However, the recorded information and the execution may present a shift of phase and even an opposition of phase. The Test of Folding a Rhombus (TFR) was conceived to assess the fluctuation and articulation of these processes. It was proposed to 60 elderly individuals divided into 2 groups (30 subjects with cognitive disorders - case group - and 30 subjects without cognitive disturbance - control group -), and was applied at different time schedules of the day (8:00, 11:00, 15:00 and 18:00 h) once a week during 4 weeks. Its purpose was to quantify the relationship between automatic and controlled processes. Statistical analysis indicates significant circadian differences during the evolution of the two processes between the case and control groups. Simple, fast and easy to use, the TFR can also help professionals to choose the best automatic or controlled processes activity according to the need of patients.
