test-retest reliability and minimal detectable change for center of pressure measures of postural stability in elderly subjects
Authors
abstract
abstract background: postural instability has been identified as a potential precursor of falls in elderly subjects. postural stability in quiet stance is commonly assessed with center of pressure (cop) measures. the purpose of this study was to determine testretest reliability and minimal detectable change (mdc) for the center of pressure (cop) measures in the elderly subjects. methods: eighteen healthy elderly people over the age of 60 years participated in this study. for each subject the cop was recorded during quiet upright stance on different levels of postural difficulty (eyes open versus eyes closed, firm surface versus foam surface) and lean condition (forward and backward). all measurements were done on two sessions with 7 days interval. these indices: mean velocity, standard deviation of amplitude, standard deviation of velocity, phase plane parameter and area (95% confidence ellipse). intraclass correlation coefficient (icc), standard error of measurement (sem) and coefficient of variation (cv) were used to quantify testretest reliability. the mdc for each measure was calculated to quantify intervention effects. results: in general, test-retest reliability of cop measures in the elder subjects was increased whenever postural difficulty of task increased in quiet standing. in standing conditions, mean velocity and phase plane parameter were the most sensitive and the most reliable measures. the lean range was the most sensitive and the most reliable measure, in the lean conditions. conclusion: center of pressure measures in the quiet standing especially in difficult postural conditions demonstrated high sensitivity in the older subjects. these results may be useful in quantification and assessment of balance performance and treatment efficacy.

Purpose: The first step to manage motor impairment of upper limb in patients with subacute stroke is having an accurate assessment tool. The Fugl-Meyer assessment of upper extremity and 9-hole pegboard test are used to evaluate motor function and hand dexterity in stroke survivals. The present study aimed to investigate the test-retest reliability and minimal detectable change (MDC) in these tw...

[Purpose] The purpose of this study is to evaluate the reliability of linear and nonlinear measures of the center of pressure (COP) during visual deprivation. [Subjects and Methods] Fifteen young adults participated in this study. COP signals were recorded in two conditions: eyes open and eyes closed. Three trials were performed in each condition with a rest period of approximately 1 min. The i...
