Nuts and bolts of conducting feasibility studies / Linda TICKLE-DEGNEN in American Journal of Occupational Therapy, Vol. 67/2 (mars-avril 2013)

Public ISBD [article]  inAmerican Journal of Occupational Therapy > Vol. 67/2 (mars-avril 2013) . - p. 171-176 Titre : Nuts and bolts of conducting feasibility studies Type de document : texte imprimé Auteurs : Linda TICKLE-DEGNEN Année de publication : 2013 Article en page(s) : p. 171-176 Langues : Anglais (eng) Mots-clés : Essai comparatif  Etude faisabilité Résumé : Many factors can affect the successful implementation and validity of intervention studies. A primary purpose of feasibility and pilot studies is to assess the potential for successful implementation of the proposed main intervention studies and to reduce threats to the validity of these studies. This article describes a typology to guide the aims of feasibility and pilot studies designed to support the development of randomized controlled trials and provides an example of the studies underlying the development of one rehabilitation trial. The purpose of most feasibility and pilot studies should be to describe information and evidence related to the successful implementation and validity of a planned main trial. Null hypothesis significance testing is not appropriate for these studies unless the sample size is properly powered. The primary tests of the intervention effectiveness hypotheses should occur in the main study, not in the studies that are serving as feasibility or pilot studies.

Systematic review of the effectiveness of occupational therapy-related interventions for people with Parkinson's disease. / Erin R. Foster in American Journal of Occupational Therapy, Vol. 68/1 (janvier-février 2014)

Public ISBD [article]  inAmerican Journal of Occupational Therapy > Vol. 68/1 (janvier-février 2014) . - p.39-49 Titre : Systematic review of the effectiveness of occupational therapy-related interventions for people with Parkinson's disease. Type de document : texte imprimé Auteurs : Erin R. Foster ; Mayuri BEDEKAR ; Linda TICKLE-DEGNEN Année de publication : 2014 Article en page(s) : p.39-49 Langues : Anglais (eng) Mots-clés : Thérapie cognitive  Environnement  Ergothérapie  Maladie Parkinson Résumé : We describe the results of a systematic review of the literature on occupational therapy–related interventions for people with Parkinson’s disease (PD). Three broad categories of intervention emerged: (1) exercise or physical activity; (2) environmental cues, stimuli, and objects; and (3) self-management and cognitive–behavioral strategies. Moderate to strong evidence exists for task-specific benefits of targeted physical activity training on motor performance, postural stability, and balance. Low to moderate evidence indicates that more complex, multimodal activity training supports improvement in functional movement activities. The evidence is moderate that the use of external supports during functional mobility or other movement activities has positive effects on motor control. In addition, moderate evidence is available that individualized interventions focused on promoting participant wellness initiatives and personal control by means of cognitive–behavioral strategies can improve targeted areas of quality of life. The implications for practice, education, and research are discussed.
