Among these modalities, dance therapy seems to be particularly interesting since it is an enjoyable physical activity that combines improvisation, music and social interaction. A 12-week dance therapy program (DTP) offered to rehabilitation outpatients aims to promote community participation and mobility. Its effectiveness has never been studied. The objective was thus to determine the effect of DTP on participants’ mobility and participation compared to that of persons only receiving rehabilitation. Material and method A pre-/post-intervention repeated measures design with a comparison group was used (2 evaluations each pre and post-intervention). Participants were receiving outpatient rehabilitation at the Lucie-Bruneau Rehabilitation Centre (Montreal, Quebec). Outcomes measures included Timed up and go (TUG), Assessment of life habits (LIFE-H) relating to community mobility and community life, and number of leisure activities performed. Generalized Estimating Equations over repeated measures determined if groups evolved differently over time; paired t-tests assessed change among DTP participants in Flow state scale (FSS-2) scores pre-/post-intervention. Results Forty-three DTP and 50 control subjects participated (half were male, average age of 49.1 ± 14.2 years). Subjects in both groups significantly (P Conclusion Rehabilitation clients enjoy DTP however DTP appears to have limited added value beyond the provision of usual rehabilitation. Non-significant results are likely due to the choice of outcome measures.

Interest of rehabilitation in dementia and evolutive diseases has also been discussed during the last few years. Regu le 10 septembre 1999 : accept~ le 26 novembre 1999 Methods: We report the case of a 55 years old patient who stayed at the hospital for rehabilitation of FTD. He had important cognitive impairments and major difficulties in everyday life activities. Discussion: Frontal rehabilitation strategies are discussed, Two strategies can be used, one neuropsychological, the other based on everyday life activities evaluation.

They are also known to be a frequent sequel of traumatic brain injury, where patients may exhibit severe long-standing impairments in instrumental activities of daily living. One could therefore expect that cerebral lesions affecting executive functioning would result in more severe impairments in older patients. We previously developed an ecological assessment of executive functions, consisting of a cooking task, requiring multitasking abilities and known to be sensitive to a dysexecutive syndrome [Cortex 36 (2000) 649-669]. The aim of this study was to analyze the effect of age on the cognitive and ecological assessments of executive functions in a group of patients with acquired brain injury (ABI) resulting in a dysexecutive syndrome. Studies in this area usually focus on patients older than 60 or 65, but we chose to analyze the effect of age in a younger population. We hypothesized that older patients would have poorer performances on the cognitive and ecological tests of executive functioning, when compared to younger patients. Forty-five patients with ABI resulting in frontal lesions and a dysexecutive syndrome participated in this study. Patients underwent a comprehensive battery of cognitive tests assessing executive functioning, as well as the cooking task. We also studied a group of 12 control subjects who performed the cooking task. No effect of age was found on performance in the cooking task in the control group. Age was not related to demographic parameters or injury severity in the ABI group. Although the ABI group was relatively young (mean age: 40.3 years (S.D.=12.5), ranging from 17 to 63), results indicated a significant deleterious effect of age on the cognitive tests of executive functioning in the ABI group. We also highlighted a significant worsening of patients' performance in the cooking task with age, and this effect was found on several variables of task analysis: the number of errors and occurrence of dangerous behaviors. Our study demonstrates the deleterious effect of aging on cognitive and ecological assessment of executive functioning after ABI. The strength of this study is that it deviated from the traditional age considered in studies of elderly populations and focused on younger patients. It is therefore important to consider the implication that this may have on a patient's rehabilitation program and postinjury discharge.

The aims of this study were to use a naturalistic experimental task to assess patients' disabilities, and to study the nature of the cognitive disorders underlying them. Execution of a cooking task involving multi-tasking (Chevignard et al., 2000) was studied in 45 patients with a dysexecutive syndrome following acquired brain injury. Patients made significantly more errors and were slower than controls; more than half of the patients did not achieve the goal and demonstrated dangerous behaviours. Those results were significantly correlated to the results of the Six Elements Task and to a behavioural questionnaire. They were also correlated to brain injury severity and to patients' cooking habits. This naturalistic assessment is clinically relevant to better assess patients' dysexecutive impairments in complex activities of daily living. Correlations of the results in the cooking task with the neuropsychological assessment highlighted the role of the dysexecutive syndrome in patients' disabilities, indicating control alterations rather than planning disorders, difficulty in dealing with the environment, and inhibiting inappropriate actions. The role of attention and prospective memory was also underlined, whereas other cognitive functions did not influence task performance.
