Postural control in the elderly: an analysis of test-retest and interrater reliability of the COP-COM variable.

摘要: Abstract Corriveau H, Hebert R, Prince F, Raiche M. Postural control in the elderly: an analysis of test-retest and interrater reliability COP-COM variable. Arch Phys Med Rehabil 2001;82:80-5. Objectives: To estimate center pressure-center mass (COP-COM) variable postural elderly. Design: The biomechanic COP-COM, which represents distance between COP COM, was determined from 2 AMTI force platforms 3 OPTOTRAK® position sensors. Measurements were taken quiet position, double leg stance, eyes open closed conditions. Setting: Laboratory environment. Participants: Forty-five healthy subjects, 8 patients with diabetes neuropathy, 7 stroke survivors, all whom at least 60 years old. Interventions: Subjects evaluated on separate occasions within days by same evaluator to determine reliability. Interrater day. Main Outcome Measures: COM terms root mean square. 4 trials for each condition used statistical analysis. Intraclass correlation coefficients (ICCs) used. Results: has good both studies, but its varies according direction COP-COM. For ICC ranged from.89 to.93 anteroposterior from.74 to.79 mediolateral direction. Conclusion: equivalence obtained suggests that measurement error is mainly linked biologic variability this measure over a short period time. Using stabilizes enough be potentially evaluate clinical change. © 2001 American Congress Rehabilitation Medicine Academy Physical
