RESUMEN

PURPOSE: To understand the applicability and unique contributions of global positioning system (GPS) and geographic information system (GIS) technologies to investigate individuals' participation in the community. METHODS: A scoping review was conducted to summarize studies that employed GPS and/or GIS to assess community participation. Systematic literature searches were performed using nine electronic databases, up to April 2022. Two independent reviewers screened studies for eligibility and extracted data from the selected studies. RESULTS: The searches retrieved 628 articles, of which 36 met the inclusion criteria. In 31 studies, a GPS unit or GPS-enabled device monitored the community mobility of individuals with different health conditions. Tracking periods varied from five hours to 30 consecutive days. The spatiotemporal parameters obtained from satellite-based data provided information about individuals' presence in the community. Most studies combined GPS with other measuring tools (self-report diaries/questionnaires, qualitative interviews) to capture a broader description of community participation. CONCLUSIONS: GPS and GIS are viable approaches for advancing research as they provide unique information about community participation not easily captured by other methods. The combination of available methods comprehensively address the physical and social dimensions of this construct.IMPLICATIONS FOR REHABILITATIONGlobal positioning system (GPS) and geographic information system (GIS) technology allows direct and real-time quantification of patterns of individuals' community mobility.The geographic area where individuals participate in daily living activities complements information from self-report diaries/questionnaires.Combining GPS technology with self-report diaries/questionnaires allows a broader description of individuals' community participation, addressing respectively both its physical and social dimensions.Knowledge of individuals' access to and involvement in community locations/situations may help therapists design interventions to improve community participation.

RESUMEN

O objetivo do estudo foi compreender fatores que influenciam a participação de adolescentes com paralisia cerebral (PC) na Educação Física Escolar. Dez adolescentes com PC foram entrevistados utilizando roteiro de entrevista semiestruturado, cujo conteúdo foi gravado, transcrito e submetido à Análise de Conteúdo. Três categorias e sete subcategorias emergiram dessa análise. Verificou-se que fatores ambientais (atitudinais e físicos) e pessoais influenciaram a participação. Especificamente, as atitudes de colegas, professores e monitores, bem como a disponibilidade de dispositivos de auxílio para marcha e a acessibilidade física da escola foram elementos importantes que impactaram, negativamente ou positivamente, a participação na Educação Física. Características pessoais, como medo de realizar as atividades e baixa ou alta percepção de autoeficácia, também influenciaram o engajamento dos adolescentes na Educação Física e devem ser consideradas por profissionais da Educação Física e reabilitação

The aim of the study was to understand factors influencing participation of adolescents with cerebral palsy (CP) in school Physical Education (PE). Semi-structured interviews were conducted with ten adolescents with CP. The interviews were recorded, transcribed and submitted to content analysis, resulting in three categories and seven subcategories. Environmental (attitudinal and physical) and personal factors influenced participation. Specifically, attitudes of peers, teachers and instructors, and availability of mobility devices and physical accessibility were important elements that influenced ­ negatively or positively ­ participation in PE. Personal characteristics such as fear of performing activities and low or high self-efficacy perception also influenced the engagement of adolescents in PE and should be considered by teachers and rehabilitation professionals

RESUMEN

Aiming hand-held tools at targets in space entails adjustments in the dynamical organization of aiming patterns according to the required precision. We asked whether and how these adjustments are modified by the tool's mass distribution. Twelve participants performed reciprocal aiming movements with a 50-cm long wooden probe. Kinematic patterns of probe movements were used as a window into the behavioral dynamic underlying performance of a reciprocal aiming task. We crossed three levels of task difficulty (IDs 2.8, 4.5 and 6.1) with two types of probe varying in their mass distribution (proximal vs distal loading). Movement duration was affected by task difficulty and probe loading (shorter for larger targets and proximal probe loading). Progressive deviations from a sinusoidal movement pattern were observed as task difficulty increased. Such deviations were more pronounced with proximal probe loading. Results point to a higher degree of non-linearity in aiming dynamics when the probe was loaded proximally, which might reflect employment of additional perceptual-motor processes to control the position of its less stable tip at the vicinity of the targets. More generally, the effects of probe loading on aiming pattern and dynamics suggest that perceptual-motor processes responding to task level constraints are sensitive to, and not independent from, biomechanical, end-effector constraints.

RESUMEN

Individuals with unilateral cerebral palsy (CP) demonstrate reduced performance in upper limb tasks compared to typically developing (TD) peers. We examined whether task conditions modify differences between teenagers with and without CP during a reciprocal aiming task. Twenty teenagers (nine CP and 11 TD) moved a pointer between two targets as fast as possible without missing a target. Task conditions were manipulated by changing the targets' size, by modifying the inertial properties of the pointer and by varying the upper limb used to perform the task (preferred/non-affected and non-preferred/affected upper limbs). While compared to TD peers, CP teenagers exhibited lower performance (longer movement times). Such differences were attenuated when the task was performed with the preferred upper limb and when accuracy requirements were less stringent. CP teenagers were not differentially affected by the pointer inertia manipulation. Task conditions not only affected performance but also joint kinematics. CP teenagers revealed less movement at the elbow and more movement at the shoulder when performing the task with their less skilled upper limb. However, both CP and TD teenagers demonstrated a larger contribution of trunk movement when facing more challenging task conditions. The overall pattern of results indicated that the joint kinematics employed by individuals with unilateral CP constituted adaptive responses to task requirements. Thus, the explanation of the effects of unilateral CP on upper limb behavior needs to go beyond a context-indifferent manifestation of the brain injury to include the interaction between task demands and action capabilities.
