“…This study replicated the widely reported differences between teenagers with and without CP in their performance of upper limb tasks and related joint kinematics (Mackey et al 2006;Steenbergen and Meulenbroek 2006;Rönnqvist and Rösblad 2007;Smits-Engelsman et al 2007;Jaspers et al 2009Jaspers et al , 2011: Overall, CP teenagers demonstrated longer movement times on a reciprocal aiming task than their TD peers, and this reduced performance was accompanied by lower magnitudes of elbow motion and larger magnitudes of shoulder and trunk motion.

“…In upper limb task performance, the most consistently observed differences between unilateral CP and typically developing (TD) teenagers include longer movement durations, reduced trajectory straightness and lower peak velocities exhibited by the former (Mackey et al 2006;Steenbergen and Meulenbroek 2006;Smits-Engelsman et al 2007;Domellöf et al 2009;Jaspers et al 2009Jaspers et al , 2011. Compared to their TD peers, teenagers with unilateral CP have also consistently been shown to demonstrate diminished magnitude of elbow extension and increased magnitude of trunk flexion and/or rotation (Mackey et al 2006;Steenbergen and Meulenbroek 2006;Butler et al 2010;Reid et al 2010;Jaspers et al 2009Jaspers et al , 2011.…”

“…Earlier research designed to identify differences in upper limb function between individuals with CP and their TD age-matched peers involved a variety of upper limb tasks: reaching forward, upward and sideways; reaching to grasp different objects; directing the hand to the mouth, to the head or to the contralateral shoulder; and performing fast aiming movements toward targets positioned at different locations, among others (Van Thiel et al 2000;Mackey et al 2006;Steenbergen and Meulenbroek 2006;Rönnqvist and Rösblad 2007;Smits-Engelsman et al 2007;Domellöf et al 2009;Jaspers et al 2009Jaspers et al , 2011Butler et al 2010;Reid et al 2010). The experimental protocols of most of these studies did not include systematic manipulations of the conditions under which the task was performed, such as precision and speed requirements, quality of the tool or upper limb used for performance (for exceptions, see Van Thiel et al 2000;Steenbergen and Meulenbroek 2006;and Smits-Engelsman et al 2007).…”

Upper limb performance and the structuring of joint movement in teenagers with cerebral palsy: the reciprocal role of task demands and action capabilities

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.

“…During UL reaching tasks, children and adults with hemiparesis use excessive trunk displacement, compared with control subjects, to assist arm end point displacement when they have a restricted range of voluntary elbow extension and/or disrupted elbow/shoulder interjoint coordination. 3,7 Thus, measurement of only motor performance variables may provide an incomplete assessment of motor abilities of individuals poststroke.…”

Background and Purpose-Upper limb motor impairment poststroke is commonly evaluated using clinical outcome measures such as the Fugl-Meyer Assessment. However, most clinical measures provide little information about motor patterns and compensations (eg, trunk displacement) used for task performance. Such information is obtained using movement quality kinematic variables (joint ranges, trunk displacement). Evaluation of movement quality may also help distinguish between levels of motor impairment severity in individuals poststroke. Our objective was to estimate concurrent and discriminant validity of movement quality kinematic variables for pointing and reach-to-grasp tasks. Methods-A retrospective study of kinematic data (sagittal trunk displacement, shoulder flexion, shoulder horizontal adduction, elbow extension) and Fugl-Meyer Assessment scores from 86 subjects (subacute to chronic stroke) performing pointing and reaching tasks was done. Multiple and logistic regression analyses were used to estimate concurrent and discriminant validity respectively. Cutoff points for distinguishing between levels of upper limb motor impairment severity (mild, moderate to severe) were estimated using sensitivity/specificity decision plots. The criterion measure used was the Fugl-Meyer Assessment (upper limb section). Results-The majority of variance in Fugl-Meyer Assessment scores was explained by a combination of trunk displacement and shoulder flexion (51%) for the pointing task and by trunk displacement alone (52%) for the reach-to-grasp task. Trunk displacement was the only variable that distinguished between levels of motor impairment severity. Cutoff points were 4.8 cm for pointing and 10.2 cm for reach-to-grasp movements. Conclusion-Movement

“…The tridimensional kinematics of the UULL is technically more challenging, due to the great complexity of the shoulder joint movement 11 . However, biomechanical models for UL have been used 8,12 , and studies that assess functional tasks with the use of this tool have been described in literature for the infant population with cerebral palsy, mostly in the hemiparetic spastic type, for being more prevalent 13 . Since there are a few studies in literature correlating the methods of qualitative and quantitative evaluation of the movement in the population with the dyskinetic type, this study aimed at verifying a possible correlation between the quantitative kinematic variables and the qualitative manual ability during the action of bringing a mug towards the mouth among adults in the analyzed population.…”

| The aim of this study was to verify relation between kinematic variables of temporal-spatial parameters and manual ability and between own temporal-spatial variables during the movement of bring a mug to the mouth in adults with dyskinetic cerebral palsy (DCP). Sixteen adults with DCP were evaluated by MACS (Manual Ability Classification System), and by temporal-spatial variables of tridimensional kinematics of the movement to bring a bug to the mouth by means of 9 cameras infra-red Vicon ® MX 40 (Oxford Metrics Group, Oxford, UK). The Spearman correlation coefficient (ρ) was used to correlate variables. As a result, we found weak correlation between the classification of manual ability and the adjusting phase (ρ=0.219), the velocity variables − average velocity (ρ=-0.313), peak velocity (ρ=-0.282) and time to peak velocity (ρ=-0.250).No correlation was found between the variables going and returning phase and MACS. Moderate correlation was found between going and returning phase (ρ=0.559), between the going phase and time to peak velocity (ρ=0.518) and between the adjusting phase and peak velocity (ρ=-0.562). A strong correlation was found between the mean velocity and peak velocity (ρ=0.947) and between the adjusting phase and average velocity (ρ=-0.635).In conclusion, functional impairment may be related to longer adjusting phase and decrease of movement speed in subjects with PCD. Kinematic variables were related toCorrelation between temporal-spatial parameters and manual ability of adults with dyskinetic cerebral palsy each other in moderate and strong way and indicated that the phases runtime influences the movement speed.
