“…[15][16][17] Nevertheless, fewer studies of stroke populations have investigated a more 'natural' task that more closely replicates those performed in everyday life; like moving the hand to the mouth 18 or the entire movement when reaching for a cup, grasping it, bringing it to the mouth to drink and putting the cup back on the table. [19][20][21] Even when the full task has been performed, the kinematics of only the reaching phase are usually analysed. 19,[22][23][24] A recent review summarising UE kinematics in individuals with neurological disorders, found that only 25% of the studies included Activities of Daily Living (ADL) tasks while 64% of the studies investigated reaching movements.…”

Background: Consequences of stroke frequently comprise reduced movement ability of the upper extremity (UE) and subsequent long-term disability. Clinical scales are used to monitor and evaluate rehabilitation but are often insufficient, while technological advances in 3D motion capture provide detailed kinematics to more objectively quantify and interpret movement deficits. Objectives: To provide a comprehensive overview of research using kinematic movement analysis of the UE in individuals post-stroke with focus on objectives, methodology and findings while highlighting clinical implications and future directions. Major Findings: A literature search yielded 93 studies categorised into four groups: comparative (healthy, stroke, task condition), intervention (clinical trials), methodological and longitudinal. The majority of studies used optoelectronic systems, investigated discrete reaching and involved mainly individuals with moderate or mild stroke impairment in chronic stage. About 80% of the studies were published after year 2004. Speed-related variables were most frequently addressed followed by smoothness indicators, joint angles and trunk displacement. Movements in the hemiparetic side are generally slower, less smooth and show a compensatory movement pattern. Task specificity is crucial for kinematic outcomes. Tables summarising the main characteristics, objectives and results of all included studies are provided. Conclusions: There is still a lack of studies addressing reliability and responsiveness and involving more complex, everyday UE tasks with ecological validity. To facilitate the use of UE kinematic movement analysis in clinics, a research-based simpler data handling with pre-defined output for the results, as commonly used in gait analysis, is warranted.

“…This increase in the deceleration phase of reaching tasks shows that subjects with hemiparesis need more time for feedback adjustments than healthy individuals. (van Vliet & Sheridan, 2007) Data shows that the greater MT for paretic UL in people with hemiparesis may be related to lower peak velocity values as well as to a longer time required by subjects with hemiparesis in the deceleration phase. These results are in agreement with those carried out by Lang et al (2006) that showed that stroke patients had deficits in movement peak velocity as well as longer deceleration phase.…”

Abstract-The purpose of this study was using an accelerometer to access the kinematics of reach-to-grasp movements in subjects with hemiparesis. Eight subjects (59.4 ± 6.9 years old) with chronic hemiparesis (50.9 ± 25.8 months post-stroke) participated in this study. Kinematic assessment was performed using a triaxial accelerometer (EMG Systems, Brazil) attached to the subjects' forearm. Ten reach-to-grasp movements of grabbing a 500ml-size bottle were performed by the subjects with the paretic and the non-paretic upper limbs (ULs). The following spacetemporal variables were calculated and used to compare the paretic and non-paretic ULs: movement time (MT), time to reach the peak velocity, absolute and relative (TPV and TPV%MT), relative deceleration duration (DEC%MT), time to peak acceleration (TPA) and peak hand acceleration (PA). Movements were slower in the paretic UL with increased MT, TPA and DEC. The accelerometer allowed to identify of changes in reaching-to-grasp movements of subjects with hemiparesis. When complex systems are not available, accelerometers can be an alternative to measure UL movements.

O objetivo deste estudo foi usar um acelerometro para avaliar a cinemática do movimento de alcance e preensão de indivíduos com hemiparesia. Participaram deste estudo oito indivíduos (59,4 ± 6,9 anos) com hemiparesia crônica (50,9 ± 25,8 meses pós-AVE). A avaliação cinemática foi realizada através de acelerômetro triaxial (EMG Systems do Brasil) fixado no antebraço. Os indivíduos realizaram 10 movimentos de alcançar uma garrafa de 500 ml pelo membro superior (MS) parético e não parético. As seguintes variáveis espaço-temporais foram calculadas e utilizadas para comparar o MS parético e não parético: tempo de movimento (TM), tempo para alcançar o pico de velocidade, absoluto e relativo (TPV e TPV%TM), duração relativa da desaceleração(DEC%TM), tempo para alcançar o pico de aceleração (TPA) e pico de aceleração da mão (PA). Os movimentos foram mais lentos no MS parético com maiores TM, TPA e DEC. A utilização do acelerômetro permitiu identificar alterações no movimento de alcance em indivíduos com hemiparesia. Quando sistemas mais compexos não são disponiveis, acelerometros podem ser uma alternativa para medir o movimento do MS.

“…One study showed that participants with stroke affecting the territory of the MCA have less significant correlations between the above events compared to healthy participants, both at the start of the reach and at the time of maximum aperture 3 . In two further groups of patients with heterogenous stroke lesion sites, two patients did not begin their hand opening until near the end of the transport 4 and there was an impaired ability to adjust timing of grasp for different sized objects 11 .…”

Coordination Between Reaching and Grasping in Patients With Hemiparesis and Healthy Subjects

Abstract: The hemiparetic patients, who had a moderate amount of functional recovery, were similar to healthy subjects in their ability to control reach-to-grasp components. Their performance was not as skilled, however.
