Contribution of Head Position, Standing Surface, and Vision to Postural Control in Community-Dwelling Older Adults / Fredrick D. POCIASK in American Journal of Occupational Therapy, Vol. 70/1 (janvier-février 2016)

Public ISBD [article]  inAmerican Journal of Occupational Therapy > Vol. 70/1 (janvier-février 2016) Titre : Contribution of Head Position, Standing Surface, and Vision to Postural Control in Community-Dwelling Older Adults Type de document : texte imprimé Auteurs : Fredrick D. POCIASK ; Rosanne DiZAZZO-MILLER ; Allon GOLDBERG ; et al. Année de publication : 2016 Langues : Anglais (eng) Mots-clés : Personne âgée  Tête  Posture  Chute  Déséquilibre Résumé : Postural control requires the integration of sensorimotor information to maintain balance and to properly position and orient the body in response to external stimuli. Age-related declines in peripheral and central sensory and motor function contribute to postural instability and falls. This study investigated the contribution of head position, standing surface, and vision on postural sway in 26 community-dwelling older adults. Participants were asked to maintain a stable posture under conditions that varied standing surface, head position, and the availability of visual information. Significant main and interaction effects were found for all three factors. Findings from this study suggest that postural sway responses require the integration of available sources of sensory information. These results have important implications for fall risks in older adults and suggest that when standing with the head extended and eyes closed, older adults may place themselves at risk for postural disequilibrium and loss of balance.

Randomized controlled trial comparing tailoring methods of multimedia-based fall prevention education for community-dwelling older adults / Stacey L. SCHEPENS in American Journal of Occupational Therapy, Vol. 65/6 (novembre-décembre 2011)

Public ISBD [article]  inAmerican Journal of Occupational Therapy > Vol. 65/6 (novembre-décembre 2011) . - p. 702-709 Titre : Randomized controlled trial comparing tailoring methods of multimedia-based fall prevention education for community-dwelling older adults Type de document : texte imprimé Auteurs : Stacey L. SCHEPENS ; Allon GOLDBERG ; Victoria PANZER Année de publication : 2011 Article en page(s) : p. 702-709 Langues : Anglais (eng) Mots-clés : Vertige  Education  Comportement Résumé : OBJECTIVE. We attempted to determine whether multimedia fall prevention education using different instructional strategies increases older adults’ knowledge of fall threats and their fall prevention behaviors. METHOD. Fifty-three community-dwelling older adults were randomized to two educational groups or a control group. Multimedia-based educational interventions to increase fall threats knowledge and encourage fall prevention behaviors had two tailoring strategies: (1) improve content realism for individual learners (authenticity group) and (2) highlight program goals and benefits while using participants’ content selections (motivation group). Knowledge was measured at baseline and 1-mo follow-up. Participants recorded prevention behaviors for 1 mo. RESULTS. Intervention group participants showed greater knowledge gains and posttest knowledge than did control group participants. The motivation group engaged in more prevention behaviors over 1 mo than did the other groups. CONCLUSION. Tailoring fall prevention education by addressing authenticity and motivation successfully improved fall threats knowledge. Combining motivational strategies with multimedia education increased the effectiveness of the intervention in encouraging fall prevention behaviors.
