Acceptability of Two Perturbation-based Balance Training Paradigms: Perturbation Treadmill vs Dynamic Stability Training in the Presence of Perturbations.
INTRODUCTION
Perturbation-based balance training is promising for fall prevention in older adults mimicking real-life fall situations at a person's stability thresholds to improve reactive balance. Hence, it can be associated with anxiety, but knowledge about the acceptability of perturbation-based balance training is scarce.
METHOD
This is a secondary analysis of a randomized controlled trial comparing effects of two different perturbation-based balance training paradigms that aims to evaluate and compare the acceptability of those training paradigms in fall-prone older adults. Participants (74.9±5.7 years) who completed the training (6 weeks, 3x/week) on either a perturbation treadmill (PBTtreadmill: n=22) or unstable surfaces in the presence of perturbations (PBTstability: n=27) were surveyed on the acceptability of perturbation-based balance training using a 21-items questionnaire addressing seven domains (perceived effectiveness, tailoring, demand, safety, burden, devices, affective attitude), based on the Theoretical Framework of Acceptability and context-specific factors. Relative scores (% of absolute maximum) for single items and domains were calculated.
RESULTS
Median domain scores of perceived effectiveness, tailoring, safety, devices, and affective attitude were all ≥70% for both paradigms. The highest scores were obtained for tailoring (both paradigms=100% [interquartile range 80-100%]). Domain scores of demand and burden were in the medium range (40-45%) for both paradigms. No significant differences between paradigms were found for any domain score. Two single items of safety differed significantly, with PBTtreadmill perceived as needing less support (p=.015) and leading less often to balance loss (p=.026) than PBTstability.
CONCLUSION
Perturbation-based balance training conducted on a perturbation treadmill or on unstable surfaces is well accepted in this fall-prone older sample, even though it is conducted at individual stability thresholds. Tailoring may play a key role in achieving high levels of perceived effectiveness, appropriate levels of demand and burden, and high sense of safety. Perturbation-based balance training delivered on treadmills might be more appropriate for more anxious persons.
期刊介绍:
In view of the ever-increasing fraction of elderly people, understanding the mechanisms of aging and age-related diseases has become a matter of urgent necessity. ''Gerontology'', the oldest journal in the field, responds to this need by drawing topical contributions from multiple disciplines to support the fundamental goals of extending active life and enhancing its quality. The range of papers is classified into four sections. In the Clinical Section, the aetiology, pathogenesis, prevention and treatment of agerelated diseases are discussed from a gerontological rather than a geriatric viewpoint. The Experimental Section contains up-to-date contributions from basic gerontological research. Papers dealing with behavioural development and related topics are placed in the Behavioural Science Section. Basic aspects of regeneration in different experimental biological systems as well as in the context of medical applications are dealt with in a special section that also contains information on technological advances for the elderly. Providing a primary source of high-quality papers covering all aspects of aging in humans and animals, ''Gerontology'' serves as an ideal information tool for all readers interested in the topic of aging from a broad perspective.
