Three-dimensional kinematic motion analysis of a daily activity drinking from a glass: a pilot study

摘要: Development of reliable and objective evaluation methods is required, particularly for natural goal-oriented upper-extremity tasks. Three-dimensional imaging measurement techniques have turned out to be a powerful tool quantitative qualitative assessment multijoint movements. The purpose this study was develop test method three-dimensional motion analysis the activity "drinking from glass" describe drinking task with kinematic variables in control subjects. A protocol developed including set-up cameras positions markers subject. included reaching, forward transport glass, drinking, back returning hand initial position. An optoelectronic system used capture. Movement times, velocities, joint angles interjoint coordination shoulder elbow were computed analyzed twenty Test-retest consistency evaluated six showed good test-retest. Phase definitions defined verified. Descriptive obtained movement positions, velocities joint. Interjoint between reaching phase high correlation. This provides detailed description task. Our approach investigate analyze daily has great clinical potential. Consequently, next step use on persons impairments disabilities upper extremities.
