An ankle joint model-based image-matching motion analysis technique

چکیده
1 This study presented a model-based image-matching (MBIM) motion analysis 2 technique for ankle joint kinematic measurement. Five cadaveric below-hip 3 specimens were manipulated through a full range of ankle joint motions in bare-foot 4 and shoed conditions. The ankle motions were analyzed by bone-pin marker-based 5 motion analysis and MBIM motion analysis techniques respectively. The root mean 6 square errors of all angles of motion were less than 3 degrees. The average Intraclass 7 Correlation Coefficients (ICCs) for the intra-rater reliability were greater than 0.928 8 and the average ICCs for the inter-rater reliability were greater than 0.948 for all 9 ranges of motion. Excellent validity, intra-rater reliability and inter-rater reliability 10 were achieved for the MBIM technique in both bare-foot and shoed conditions. The 11 MBIM technique can therefore provide good estimates of ankle joint kinematics. 12

متن کاملComparison of ankle joint kinematics of a single athlete during an ankle inversion sprain incident and normal non-injury motions
Methods Model-Based Image Matching (MBIM) motion analysis technique allows us to understand the leg movement quantitatively by analyzing the three-dimensional human motion. With validation, it has been used to obtain ankle kinematics during ankle sprain incidents in various sports [1]. In this study, a sideward cutting motion performed by a female athlete was compared against her injured incide...
متن کاملKinematics analysis of ankle inversion ligamentous sprain injuries in sports: five cases from televised tennis competitions.
BACKGROUND Ankle ligamentous sprain is common in sports. The most direct way to study the mechanism quantitatively is to study real injury cases; however, it is unethical and impractical to produce an injury in the laboratory. A recently developed, model-based image-matching motion analysis technique allows quantitative analysis of real injury incidents captured in televised events and gives im...
متن کاملتحلیل حرکت جریانات دریائی در تصاویر حرارتی سطح آب دریا
Oceanographic images obtained from environmental satellites by a wide range of sensors allow characterizing natural phenomena through different physical measurements. For instance Sea Surface Temperature (SST) images, altimetry data and ocean color data can be used for characterizing currents and vortex structures in the ocean. The purpose of this thesis is to derive a relatively complete frame...
متن کاملAnterior Ankle Arthrodesis with Molded Plate: Technique and Outcomes
Background: There is still controversy regarding the best technique for ankle arthrodesis to acheive stable rigid fixation along with reconstructing a functional plantigrade foot. Moreover, existing techniques have complictions related to stability, soft tissue covering, fusion rate, and exposure. Methods: With the anterior approach exactly on the tibialis anterior sheath, the joint was expose...
