Trunk Restraint Therapy: The Continuous Use Of The Harness Could Promote Feedback Dependence In Poststroke Patients A Randomized Trial

Fundação de Amparo à Pesquisa do Estado de São Paulo (FAPESP)Conselho Nacional de Desenvolvimento Científico e Tecnológico (CNPq)The objective of this study was to evaluate the long-term effects of the task-specific training with trunk restraint compared with the free one in poststroke reaching movements. The design was randomized trial. The setting was University of Campinas (Unicamp). Twenty hemiparetic chronic stroke patients were selected and randomizedinto2traininggroups: trunkrestraintgroup(TRG) (reachingtraining with trunk restraint) and trunk free group (TFG) (unrestraint reaching). Twenty sessions with 45minutes of training were accomplished. The patientswere evaluated in pretreatment (PRE), posttreatment (POST) and 3 months after the completed training (RET) (follow-up). Main outcome measures were modified Ashworth scale, Barthel index, Fugl-Meyer scale, and kinematic analysis (movement trajectory, velocity, angles). A significant improvement, which maintained in the RET test, was found in the motor (P< 0.001) and functional (P = 0.001) clinical assessments for both groups. For trunk displacement, only TFG obtained a reduction statistical significance fromPRE to the POST test (P = 0.002), supporting this result in the RET test. Despite both groups presenting a significant increase in the shoulder horizontal adduction (P = 0.003), only TRGshowed a significant improvement in the shoulder (P = 0.001 -PRE to POST and RET) and elbow (P = 0.038 -PRE to RET) flexion extension, and in the velocity rate (P = 0.03 -PRE to RET). The trunk restraint therapy showed to be a long-term effective treatment in the enhancement of shoulder and elbow active joint range and velocity rate but not in the maintenance of trunk retention.9412Fundação de Amparo à Pesquisa do Estado de São Paulo (FAPESP)Conselho Nacional de Desenvolvimento Científico e Tecnológico (CNPq)Fundação de Amparo à Pesquisa do Estado de São Paulo (FAPESP)Conselho Nacional de Desenvolvimento Científico e Tecnológico (CNPq)FAPESP [06/61199-5]CNPq [302189/2004-1

Trunk Restraint Therapy: The Continuous Use Of The Harness Could Promote Feedback Dependence In Poststroke Patients: A Randomized Trial.

The objective of this study was to evaluate the long-term effects of the task-specific training with trunk restraint compared with the free one in poststroke reaching movements. The design was randomized trial. The setting was University of Campinas (Unicamp). Twenty hemiparetic chronic stroke patients were selected and randomized into 2 training groups: trunk restraint group (TRG) (reaching training with trunk restraint) and trunk free group (TFG) (unrestraint reaching). Twenty sessions with 45 minutes of training were accomplished. The patients were evaluated in pretreatment (PRE), posttreatment (POST) and 3 months after the completed training (RET) (follow-up). Main outcome measures were modified Ashworth scale, Barthel index, Fugl-Meyer scale, and kinematic analysis (movement trajectory, velocity, angles). A significant improvement, which maintained in the RET test, was found in the motor (P < 0.001) and functional (P = 0.001) clinical assessments for both groups. For trunk displacement, only TFG obtained a reduction statistical significance from PRE to the POST test (P = 0.002), supporting this result in the RET test. Despite both groups presenting a significant increase in the shoulder horizontal adduction (P = 0.003), only TRG showed a significant improvement in the shoulder (P = 0.001--PRE to POST and RET) and elbow (P = 0.038--PRE to RET) flexion extension, and in the velocity rate (P = 0.03--PRE to RET). The trunk restraint therapy showed to be a long-term effective treatment in the enhancement of shoulder and elbow active joint range and velocity rate but not in the maintenance of trunk retention.

TRY plant trait database – enhanced coverage and open access

Plant traits - the morphological, anatomical, physiological, biochemical and phenological characteristics of plants - determine how plants respond to environmental factors, affect other trophic levels, and influence ecosystem properties and their benefits and detriments to people. Plant trait data thus represent the basis for a vast area of research spanning from evolutionary biology, community and functional ecology, to biodiversity conservation, ecosystem and landscape management, restoration, biogeography and earth system modelling. Since its foundation in 2007, the TRY database of plant traits has grown continuously. It now provides unprecedented data coverage under an open access data policy and is the main plant trait database used by the research community worldwide. Increasingly, the TRY database also supports new frontiers of trait‐based plant research, including the identification of data gaps and the subsequent mobilization or measurement of new data. To support this development, in this article we evaluate the extent of the trait data compiled in TRY and analyse emerging patterns of data coverage and representativeness. Best species coverage is achieved for categorical traits - almost complete coverage for ‘plant growth form’. However, most traits relevant for ecology and vegetation modelling are characterized by continuous intraspecific variation and trait–environmental relationships. These traits have to be measured on individual plants in their respective environment. Despite unprecedented data coverage, we observe a humbling lack of completeness and representativeness of these continuous traits in many aspects. We, therefore, conclude that reducing data gaps and biases in the TRY database remains a key challenge and requires a coordinated approach to data mobilization and trait measurements. This can only be achieved in collaboration with other initiatives

Gait Analysis Comparing Parkinson's Disease With Healthy Elderly Subjects.

There is a lack of studies comparing the kinematics data of idiopathic Parkinson's disease (IPD) patients with healthy elder (HE) subjects, and when there is such research, it is not correlated to clinical measures. To compare the spatio-temporal and kinematic parameters of Parkinsonian gait with the HE subjects group and measure the relation between these parameters and clinical instruments. Twelve patients with IPD and fifteen HE subjects were recruited and evaluated for clinical instruments and gait analysis. There were statistically significant differences between HE group and the IPD group, in stride velocity, in stride length (SL), and in the hip joint kinematic data: on initial contact, on maximum extension during terminal contact and on maximum flexion during mid-swing. Regarding the clinical instruments there were significant correlated with in stride velocity and SL. Clinical instruments used did not present proper psychometric parameters to measure the IPD patient's gait, while the 3D system characterized it better.6881-

RESULTS: There were statistically significant differences between HE group and the IPD group, in stride velocity, in stride length (SL), and in the hip joint kinematic data: on initial contact, on maximum extension during terminal contact and on maximum flexion during mid-swing.

OBJETIVO: Comparar os parâmetros espaço-temporais e cinemáticos da marcha na DP com os de idosos saudáveis (IS) e avaliar a relação entre estes parâmetros com os instrumentos clínicos. MÉTODO: Doze pacientes com DPI e quinze IS foram recrutados e avaliados por instrumentos clínicos e de análise de marcha. RESULTADOS: Houve diferenças estatísticas significantes entre o grupo de IS e o de DPI na velocidade da marcha e no comprimento do passo (CP), nos dados cinemáticos das articulações do quadril: no contato inicial, na máxima extensão no apoio e na máxima flexão na oscilação. No que diz respeito aos instrumentos clínicos houve significativa correlação com a velocidade da marcha e SL. CONCLUSÃO: Os instrumentos clínicos utilizados não apresentaram adequados parâmetros psicométricos para a avaliação da marcha dos indivíduos com DPI, enquanto uma avaliação em 3D caracteriza melhor a marcha destes indivíduos
