          Abstract

          Resumo: Introdução Boa coordenação motora é essencial para que crianças sejam capazes de desempenhar diversas atividades cotidianas na escola, em casa e em outros ambientes sociais. Algumas crianças, no entanto, apresentam Transtorno do Desenvolvimento da Coordenação (TDC) o que dificulta tais atividades. Abordagens de realidade virtual (RV) vêm sendo utilizadas em diversos contextos da reabilitação, com destaque para o uso de jogos baseados no movimento. Objetivo Investigar a influência do uso de jogos do Microsoft Kinect® sobre o desempenho motor e funcional de uma criança de 8 anos, com TDC, com treinamento individual. Método Antes e após o treino, a coordenação motora, o condicionamento físico, o equilíbrio e o desempenho funcional nas atividades selecionadas foram avaliados com uso do Questionário de Transtorno do Desenvolvimento da Coordenação (DCDQ-Brasil), do Movement Assessment Battery for Children -2ª edição (MABC-2), do Perceived Efficacy and Goal Setting System (PEGS), da Medida Canadense de Desempenho Ocupacional (COPM) e do teste de caminhada de 2 minutos. Resultados A criança obteve ganho clinicamente significativo nos resultados da COPM, aumento na pontuação nos itens relacionados à habilidades motora grossa no DCDQ-Brasil, bem como melhora no condicionamento físico durante a intervenção, que não foram mantidos na fase pós-intervenção, sugerindo que jogos do Microsoft Kinect® devem ser melhor explorados como estratégia terapêutica para crianças com TDC. Conclusão As limitações do estudo de caso são discutidas com vistas a subsidiar estudos futuros.

          Abstract: Introduction A good motor coordination is essential to children to be able to perform daily activities at school, at home, and in other social environments. However, some children have Developmental Coordination Disorder (DCD), which makes it difficult to perform these activities. As a new approach, virtual reality is being used in different rehabilitation contexts, with an emphasis on the use of motion-based games. Objective The aim of this case study was to investigate the influence of the use of Microsoft Kinect® games on the motor and functional performance of an eight years old child with DCD, trained individually. Method Pre and post-assessment of motor coordination, physical fitness, balance, and functional performance in selected activities were conducted using the Developmental Coordination Disorder Questionnaire (DCDQ-Brazil), the Movement Assessment Battery for Children, 2nd edition (MABC-2), the Perceived Efficacy and Goal Setting System (PEGS), the Canadian Occupational Performance Measure (COPM), and the 2-minute walk test. Results The child presented clinically significant gains in the COPM, increased scores on items related to gross motor skills in the DCDQ-Brazil, as well as improvement in physical conditioning during the intervention, which was not maintained in the post-intervention phase, suggesting that the use of Microsoft Kinect® games should be further explored as therapeutic strategy for children with DCD. Conclusion The limitations of the case study are discussed as a means to subsidize future studies.

          Validity of the Microsoft Kinect for assessment of postural control.

          Clinically feasible methods of assessing postural control such as timed standing balance and functional reach tests provide important information, however, they cannot accurately quantify specific postural control mechanisms. The Microsoft Kinect™ system provides real-time anatomical landmark position data in three dimensions (3D), and given that it is inexpensive, portable and simple to setup it may bridge this gap. This study assessed the concurrent validity of the Microsoft Kinect™ against a benchmark reference, a multiple-camera 3D motion analysis system, in 20 healthy subjects during three postural control tests: (i) forward reach, (ii) lateral reach, and (iii) single-leg eyes-closed standing balance. For the reach tests, the outcome measures consisted of distance reached and trunk flexion angle in the sagittal (forward reach) and coronal (lateral reach) planes. For the standing balance test the range and deviation of movement in the anatomical landmark positions for the sternum, pelvis, knee and ankle and the lateral and anterior trunk flexion angle were assessed. The Microsoft Kinect™ and 3D motion analysis systems had comparable inter-trial reliability (ICC difference=0.06±0.05; range, 0.00-0.16) and excellent concurrent validity, with Pearson's r-values >0.90 for the majority of measurements (r=0.96±0.04; range, 0.84-0.99). However, ordinary least products analyses demonstrated proportional biases for some outcome measures associated with the pelvis and sternum. These findings suggest that the Microsoft Kinect™ can validly assess kinematic strategies of postural control. Given the potential benefits it could therefore become a useful tool for assessing postural control in the clinical setting. Copyright © 2012 Elsevier B.V. All rights reserved.

            Evaluation of the Kinect™ sensor for 3-D kinematic measurement in the workplace.

            Recording posture and movement is important for determining risk of musculoskeletal injury in the workplace, but existing motion capture systems are not suited for field work. Estimates of the 3-D relative positions of four 0.10 m cubes from the Kinect were compared to estimates from a Vicon motion capture system to determine whether the hardware sensing components were sensitive enough to be used as a portable 3-D motion capture system for workplace ergonomic assessments. The root-mean-squared errors (SD) were 0.0065 m (0.0048 m), 0.0109 m (0.0059 m), 0.0057 m (0.0042 m) in the x, y and z directions (with x axis to the right, y axis away from the sensor and z axis upwards). These data were collected over a range of 1.0-3.0m from the device covering a field of view of 54.0 degrees horizontally and 39.1 degrees vertically. Requirements for software, hardware and subject preparation were also considered to determine the usability of the Kinect in the field. Copyright © 2011 Elsevier Ltd and The Ergonomics Society.
