- Analysis of the backpack loading efects on the human gaitPublication . Machado, Leandro; Castro, Marcelo P. de; Abreu, Sofia; Sousa, Helena; Gonçalves, Pedro; Sousa, Filipa; Santos, Rubim; Pinto, Viviana; Vaz, Mário; Vilas-Boas, João P.Gait is a simple activity of daily life and one of the main abilities of the human being. Often during leisure, labour and sports activities, loads are carried over (e.g. backpack) during gait. These circumstantial loads can generate instability and increase biomechanicalstress over the human tissues and systems, especially on the locomotor, balance and postural regulation systems. According to Wearing (2006), subjects that carry a transitory or intermittent load will be able to find relatively efficient solutions to compensate its effects.
- Compensatory movement detection through inertial sensor positioning for post-stroke rehabilitationPublication . Borges, Carla M.; Silva, Cláudia; Salazar, António J.; Silva, Ana S.; Correia, Miguel V.; Santos, Rubim; Vilas-Boas, João P.An increasing ageing society and consequently rising number of post-stroke related neurological dysfunction patients are forcing the rehabilitation field to adapt to ever-growing demands. In parallel, an unprecedented number of research efforts and technological solutions meant for human monitoring are continuously influencing traditional methodologies, causing paradigm shifts; extending the therapist patient dynamics. Compensatory movements can be observed in post-stroke patient when performing functional tasks. Although some controversy remains regarding the functional benefits of compensatory movement as a way of accomplish a given task, even in the presence of a motor deficit; studies suggest that such maladaptive strategies may limit the plasticity of the nervous system to enhance neuro-motor recovery. This preliminary study intends to aid in the development of a system for compensatory movement detection in stroke patients through the use of accelerometry data.
