“…This is confirmed by several studies that investigated upper limbs kinematics of healthy adults in different experimental scenarios [5,6,10,11,14,15,24,36,37,39]. The variability and flexibility of upper limb movements reflect the mechanical redundancy of the musculoskeletal system.…”

Muscle force knowledge during reaching is an important research field and tools development for measuring those forces is a challenging task, especially for clinical routines. The purpose of this study was, during a simple reach-to-grasp movement, to compare forces estimation from a Hill-type model and from the EMG-to-Force Processing (EFP) method. Ten healthy male volunteers were tested. Surface EMG signals were recorded from deltoid scapular, deltoid clavicular, triceps brachii, and biceps brachii. Ten repeated measures of right upper limb kinematics had been recorded. Three reaching distances were tested: 20, 30, and 40 cm. Muscle activations were calculated and forces were estimated by the two methods. Correlations and low RMS error found between the two methods indicate that EFP is a good way to estimate muscle forces for this kind of movement. This knowledge is essential in order to integrate these forces in reaching models developed nowadays in robotic, rehabilitation, and ergonomics field of research.

Abstract.[Purpose] The purpose of this study was to investigate the effect of task-oriented training and neurodevelopmental treatment (NDT) on the sitting posture of children with cerebral palsy.[Subjects] The subjects were 10 children with spastic diplegia and cerebral palsy due to premature birth.[Methods] The control group (n=5) received NDT and the experimental group (n=5) received the task oriented approach to improve sitting balance control, 5 times per week for 6 weeks. Sitting posture was assessed the gross motor functional measure (GMFM), and electromyography (EMG) pre and post intervention.[Results] GMFM and right rectus abdominis activities showed no significant differences in either treatment. The activity strength of the left rectus abdominis, right and left erector muscles significantly increased in both groups. With regard to the difference in the GMFM and EMG between the experiment and control groups, there was no difference.[Conclusion] The results of this study suggest that the method of task-oriented training and neurodevelopmental treatment for muscle vitalization both improved the sitting posture of children with cerebral palsy.

“…Em relação ao TA, as crianças com PC tem menor amplitude de movimento de ombro, que é contrabalanceado com movimentos compensatórios de tronco, para obter maior alcance 16 . Tal compensação, provavelmente, desafia ainda mais o equilíbrio, pelo fato do centro de gravidade ser retirado da base de suporte.…”

original RESUMOObjetivo. Verificar o comprometimento do controle postural em crianças com paralisia cerebral. Método. 64 crianças foram avaliadas e divididas em quatro grupos G1: cinco e seis; G2: sete e oito; G3: nove e dez anos, com desenvolvimento típico, e; G4: cinco a 12 anos, com paralisia cerebral. O controle postural foi avaliado por meio da Escala de Equilíbrio Pediátrica, Teste de Alcance e Plataforma de Força. Resultados. O déficit no controle postural foi identificado no G4, na escala de equilíbrio pediátrica. O G4 obteve 52 pontos, quando comparadas as crianças do G2 (55,5) e G3 (56). No teste de alcance anterior houve diferença para o G4 (19cm) em relação ao G2 (25,5cm). Sobre a plataforma de força, na postura bipodal, a área do centro de pressão do G2 (1,62 cm²) e G3 (1,36 cm²) foi menor que do G4 (4,24 cm²). Conclusão. A criança com paralisia cerebral tem prejuízo no controle postural, na realização de atividades funcionais, mobilidade e área do centro de pressão, e seu desempenho aproximou-se das crianças com desenvolvimento típico na faixa etária entre cinco e seis anos.

ABSTRACTObjective. To assess the impairment of postural control in children with cerebral palsy. Method. 64 children were evaluated and divided into four groups G1: five to six; G2: seven to eight; G3: nine to ten years, with typical development and; G4: five to 12 years, with cerebral palsy. Postural control was evaluated by the Pediatric Balance Scale, Reach Test and Force Platform. Results. The deficit in postural control was identified in the G4, the pediatric balance scale G4 got 52 points, compared the children of the G2 (55.5) and G3 (56) resulted difference; in the above range test G4 (19 cm) and G2 (25.5cm) were different; on the force platform, the bipedal posture, the area of G2 center of pressure (1.62cm²) and G3 (1.36cm²) were lower than the G4 (4.24cm²). Conclusion. Children with cerebral palsy have impairment in postural control during functional activities, mobility and pressure center area, and its performance approached the typically developing children aged between five and six years.
