“…9,[35][36][37][38][39] In addition, the progress of time itself during the first 8 weeks post stroke have been found to contribute significantly to improved movement smoothness during reaching, which indicates that improvements in movement quality follow a natural logistic pattern of stroke recovery. 38 Repetitive measurements during the recovery period demonstrate that the most prominent improvements in kinematic measures (movement time, smoothness and joint angles) occurred within 5-6 weeks poststroke, and relatively little improvement was observed thereafter. 38,40 This recovery pattern in motor function, with greater gains early after stroke followed by a relative plateau phase, has been described in several longitudinal studies using traditional clinical outcomes.…”

“…31,33,35,[38][39][40][41][42][43][44][45][46][47][48] Kinematic data can be obtained during performance of a specific functional task, for example attempting to pick up a glass, or with specially designed non-functional assays, for example the finger individuation index using a cyberglove or planar reaching tasks. For both the functional tasks and the motor assays, it is possible mathematically to compute a distance between a patient's global kinematic trajectory and a control data set.…”

“…Ostatnie badania nad wzorcem kinematycznym powrotu funkcji ręki wykazały, że jakość ruchu może mieć istotne znaczenie dla wyniku poprawy funkcji KG. Kinematyczne badania kształtowania się wzorca ruchu zaraz po udarze uwidaczniają, że normalizacja ruchu podczas zdrowienia wyraża się we wzroście ilości kontrolowanych stopni swobody, tak jak obserwuje się to u zdrowych osób w tej samej grupie wiekowej [14]. W innych badaniach biomechanicznych [15] wykazano, że normalizacja kontroli motorycznej niedowładnej KG jest ściśle połączona z poprawą szczytowej prędkości, płynności ruchu, precyzji celowego ruchu, zredukowaniem błędów przy pozycjonowaniu, minimalizowaniem kompensacji przez łopatkę i tułów oraz współruchów łokcia i ramienia w czasie sięgania.…”

“…Recent investigations on the kinematic model of arm functional recovery have revealed that the quality of movement may be crucial for UL functional improvement outcome. Kinematic studies of movement pattern formation immediately after stroke highlight the fact that motor control normalization in the recovery process is expressed through an increase in the number of controlled degrees of freedom, as is the case of healthy individuals in the same age group [14]. Another biomechanical investigation [15] revealed that motor control normalization of the paretic UL is closely connected with an increase in peak velocity, movement smoothness, precision of intended movement, positioningrelated error reduction, compensation minimisation by a scapula and torso as well as co-movement of an elbow and shoulder when performing a reaching movement.…”
