Efficacy of an occupational group therapy in degenerative dementias: a controlled study in the nursing home setting
Year of Publication 2011
Objective: We investigated the effectiveness of an occupational group therapy, tailored to dementia patients, performed regularly 6 days a week, on everyday-practical capabilities and dementia-related behavior.; Methods: Fifty-six dementia patients in one nursing home in Northern Bavaria (Germany) were observed for 6 months: 28 patients in a therapy group and 28 patients in a matched controlled group. Performance tests, ADAS-kog and E-ADL-Test, were carried out blinded. Data were analyzed using adjusted mean differences for baseline and 6-months follow-up data and multiple regression analysis.; Results: The therapy leads to stabilization of everyday-practical capabilities (adjusted mean difference 4.0; 95 % CI 1.6-6.3; p = 0.002) and of dementia-related behavior (adjusted mean difference -6.8; 95 % CI -11.8–1.8; p = 0.009) compared to deterioration in the control group who received treatment as usual. The effect power (Cohen d) on everyday-practical capabilities is |0.83|. The therapy had no significant effect on cognitive capacity.; Conclusions: An occupational therapy program directed particularly to everyday-practical activities cannot slow the progression of all dementia-related symptoms, but has a main target effect on everyday-practical capabilities.; © Georg Thieme Verlag KG Stuttgart · New York.
