The quality of arm movements typically improves in the sub-acute phase of stroke affecting the upper extremity. Here, we used whole arm kinematic analysis during reaching movements to distinguish whether these improvements are due to true recovery or to compensation. Fifty-three participants with post-acute stroke performed ∼80 reaching movement tests during 4 weeks of training with the ArmeoSpring exoskeleton. All participants showed improvements in end-effector performance, as measured by movement smoothness. Four ArmeoSpring angles, shoulder horizontal (SH) rotation, shoulder elevation (SE), elbow rotation, and forearm rotation, were recorded and analyzed. We first characterized healthy joint coordination patterns by performing a sparse principal component analysis on these four joint velocities recorded during reaching tests performed by young control participants. We found that two dominant joint correlations [SH with elbow rotation and SE with forearm rotation] explained over 95% of variance of joint velocity data. We identified two clusters of stroke participants by comparing the evolution of these two correlations in all tests. In the “Recoverer” cluster (N = 19), both joint correlations converged toward the respective correlations for control participants. Thus, Recoverers relearned how to generate smooth end-effector movements while developing joint movement patterns similar to those of control participants. In the “Compensator” cluster (N = 34), at least one of the two joint correlations diverged from the corresponding correlation of control participants. Compensators relearned how to generate smooth end-effector movements by discovering various new compensatory movement patterns dissimilar to those of control participants. New compensatory patterns included atypical decoupling of the SE and forearm joints, and atypical coupling of the SH rotation and elbow joints. There was no difference in clinical impairment level between the two groups either at the onset or at the end of training as assessed with the Upper Extremity Fugl-Meyer scale. However, at the start of training, the Recoverers showed significantly faster improvements in end-effector movement smoothness than the Compensators. Our analysis can be used to inform neurorehabilitation clinicians on how to provide movement feedback during practice and suggest avenues for refining exoskeleton robot therapy to reduce compensatory patterns.

Objective To investigate the effectiveness of core stability exercises on hand functions in children with hemiplegic cerebral palsy.Methods Fifty-two children with hemiplegic cerebral palsy ranging in age from 6 years to 8 years were enrolled in this study. They were randomly assigned to two (control and study) groups. The control group received the selected physiotherapy exercises, and the study group received the same selected physiotherapy exercise program and core stability exercises. Time motor performance, gross manual dexterity, and upper extremity skills assessed using the Jebsen Taylor Hand Function Test, Box and Block Test, and Quality Upper Extremity Skill Test, respectively, were measured before and after 12 weeks of the treatment program.Results There were significant improvements in both groups by comparing the mean values of all measured variables before and after treatment (p<0.05). There were significant differences between the control and study groups with respect to all measured variables when comparing the post-treatment outcomes (p<0.05).Conclusion This study suggests that core stability exercises can be an effective intervention that may improve hand functions in children with hemiplegic cerebral palsy.

RESUMOA alteração da função manual é um dos sintomas mais incapacitantes da hemiparesia espástica resultante da Paralisia Cerebral. O indivíduo pode apresentar alterações neuromusculoesqueléticas na extremidade superior acometida, como aumento do tônus muscular, diminuição da força e prejuízos na motricidade fina. Com base nisso, o objetivo deste estudo foi avaliar os efeitos da Fisioterapia na função manual de uma criança com hemiparesia espástica. Pesquisa quase-experimental, do tipo estudo de caso, com análise comparativa antes e depois do tratamento. A amostra foi composta pelo paciente G.N., de 6 anos de idade e portador de hemiparesia espástica à direita. O protocolo de intervenção foi constituído de 12 sessões de Fisioterapia, com frequência semanal e duração de 50 minutos. A Fisioterapia baseou-se na Terapia de Contensão Induzida, no Conceito Neuroevolutivo Bobath e na Gameterapia. Para a análise antes e depois da intervenção, a escala Pediatric Motor Activity Log (PMAL) foi aplicada no primeiro e último dia de atendimento a fim de avaliar a frequência e a qualidade de movimento do membro superior acometido. Os resultados da PMAL mostraram um aumento da média da pontuação de frequência de movimento e na média da pontuação de qualidade de movimento. O presente estudo de caso evidenciou que a Fisioterapia resultou em uma maior funcionalidade do membro superior direito da criança e favoreceu aquisições de novas habilidades motoras. Além da diversidade de estímulos para o aprendizado motor, a contribuição familiar foi determinante para o sucesso do tratamento.Palavras-chave: Paralisia cerebral. Fisioterapia. Reabilitação. Extremidade superior.ABSTRACTHand function impairment is one of the most disabling symptoms of spastic hemiparesis resulting from Cerebral Palsy. Patients may present neuromusculoskeletal disorders on the affected upper extremity, such as increase of the muscle tone, decrease of strength and losses on fine motor skills. Based on that, the goal of this study is to evaluate the effects of Physical Therapy on the hand function of a child with spastic hemiparesis. Quasi-experimental design, case-study research, with comparative analysis before and after the treatment. The sample was composed of a six-year-old patient with spastic hemiparesis on the right side. The intervention protocol was constituted of twelve Physical Therapy sessions, performed weekly and with 50 minutes duration. The Physical Therapy was based on the Constraint-induced Movement Therapy, Bobath Concept and Game Therapy. In order to measure outcomes before and after the intervention, the Pediatric Motor Activity Log (PMAL) scale was applied on the first and last session for assessment of the frequency and quality of movement on the affected upper limb. The PMAL‘s results showed an increase in the average movement frequency score and in the average movement quality score. This case study showed that Physical Therapy resulted in greater upper limb functionality to the child and favored the acquisition of new motor skills. Besides the diversity of stimuli for motor learning, the family contribution was determinant for the success of the treatment.Keywords: Cerebral palsy. Physical therapy specialty. Rehabilitation.

The effect of combined pronator teres rerouting and flexor carpi ulnaris transfer on forearm rotation was prospectively studied by comparison of pre- and postoperative three-dimensional analysis of forearm range of motion in ten patients with cerebral palsy. One year postoperatively, surgery had improved maximal supination of the forearm in all patients by an average of 63°, but there was also a mean loss of 40° pronation. Forearm range of motion increased by a mean of 23°. The centre of the range of motion on average shifted 52° in the direction of supination. Based on these results of objective forearm range of motion analysis, we conclude that the common combination of pronator teres rerouting and flexor carpi ulnaris transfer in patients with cerebral palsy effectively facilitates active supination but impairs active pronation.

Introduction A computer game-based upper extremity (CUE) assessment tool is developed to quantify manual dexterity of children with Cerebral Palsy (CP). The purpose of this study was to determine test-retest reliability of the CUE performance measures (success rate, movement onset time, movement error, and movement variation) and convergent validity with the Peabody Developmental Motor Scale version 2 (PDMS-2) and the Quality of Upper Extremity Skills Test (QUEST). Methods Thirty-five children with CP aged four to ten years were tested on two occasions two weeks apart. Results CUE performance measures of five chosen object manipulation tasks exhibited high to moderate intra-class correlation coefficient (ICC) values. There was no significant difference in the CUE performance measures between test periods. With few exceptions, there was no significant correlation between the CUE performance measures and the PDMS-2 or the QUEST test scores. Conclusions The high to moderate ICC values and lack of systematic errors indicate that the CUE assessment tool has the ability to repeatedly record reliable performance measures of different object manipulation tasks. The lack of a correlation between the CUE and the PDMS-2 or QUEST scores indicates that performance measures of these assessment tools represent distinct attributes of manual dexterity.
