- Analysis and quantification of upper-limb movement in motor rehabilitation after strokePublication . Silva, R. Mariana; Sousa, Emanuel; Fonseca, Pedro; Pinheiro, Ana Rita; Silva, Cláudia; Correia, Miguel V.; Mouta, SandraIt is extremely difficult to reduce the relations between the several body parts that perform human motion to a simplified set of features. Therefore, the study of the upper-limb functionality is still in development, partly due to the wider range of actions and strategies for motor execution. This, in turn, leads to inconsistent upper-limb movement parameterization. We propose a methodology to assess and quantify the upper-limb motor execution. Extracting key variables from different sources, we intended to quantify healthy upper-limb movement and use these parameters to quantify motor execution during rehabilitation after stroke. In order to do so, we designed an experimental setup defining a workspace for the execution of the action recording kinematic data. Results reveal an effect of object and instruction on the timing of upper-limb movement, indicating that the spatiotemporal analysis of kinematic data can be used as a quantification parameter for motor rehabilitation stages and methods.
- Kinematic and electromyographic features of upper-limb movement performed by healthy and post-stroke patientsPublication . Silva, Rosa Mariana; Fonseca, Pedro; Pinheiro, Ana Rita; Vila-Chã, Carolina; Silva, Cláudia; Correia, Miguel Velhote; Mouta, SandraIt is extremely difficult to simplify the relation between several body parts, which perform human motion, into one set of features. Mainly, the upper-limb is capable of a wider range of actions, going from fine manipulation to prehension and grasping. Aiming to describe its complexity, several studies have been conducted in order to better understand the upper-limb specificities. However, most of studies restrain the task to pointing, reaching, or grasping, which seems not enough to explain the wide range of tasks possible to be performed in a daily scenario.
