“…A need exists for the development of scales to allow clinicians to isolate and quantify such key task components. Bernhardt et al 34 have described an assessment of an object manipulation task in hemiparetic patients that is based on observational analysis of movement speed, trajectory jerkiness, and path indirectness. They compared therapists' ratings of videotapes of patients performing the task to criterion measures analyzed with an instrumented motion analysis system.…”

Background and Purpose-Reaching movements made with the affected arm in hemiparetic patients are often accompanied by compensatory trunk or shoulder girdle movements, which extend the reach of the arm. We investigated the effects of the suppression of these compensatory movements on reaching ability in hemiparetic individuals. Methods-Eleven healthy and 11 hemiparetic individuals participated. Three-dimensional kinematic analysis was used to quantify reaches made to a close and a distant target (near the limit of arm's length). Unrestrained reaches were compared with those in which shoulder girdle and trunk movements were restrained by a harness. Results-During unrestrained reaching, abnormal trunk recruitment and limitations in elbow and shoulder movements were correlated with the degree of clinical stroke severity (rϭϪ0.91 to Ϫ0.96) in hemiparetic patients. During trunk restraint, ranges of elbow and shoulder joint movement increased in both groups. In addition, elbow and shoulder interjoint coordination improved. This was caused by increases in the range of joint motion as well as by a better dynamic temporal relation between joints. Conclusions-Trunk restraint allowed patients with hemiparetic stroke to make use of arm joint ranges that are present but not normally recruited during unrestrained arm-reaching tasks. Thus, the underlying "normal" patterns of movement coordination may not be entirely lost after stroke. Appropriate treatments, such as trunk restraint, may be effective in uncovering latent movement patterns to maximize arm recovery in hemiparetic patients.

“…Quality of movement (ie, jerkiness, hesitation, effort, speed, range, and overall movement normality) was analyzed by a different independent and experienced rater under blinded conditions using observational kinematic analysis and 10-point visual analogue scales (VAS). 10 A second, whole-body video identified the presence of any associated movements. Subjects recorded their perceived effort associated with the movement task at the end of the PET session using a VAS.…”

Background and Purpose-Motor recovery after stroke is associated with cerebral reorganization. However, few studies have investigated the relationship directly, and findings are equivocal. We therefore aimed to characterize the relationship between motor impairment, motor recovery, and task-related changes in regional cerebral blood flow (⌬rCBF) longitudinally. Methods-We obtained a profile of motor impairment and recovery in the upper limb and conducted positron emission tomography motor activation studies using a simple finger-tapping task in 9 stroke patients 2 to 7 weeks after stroke and 6 months later. For correlation analysis, mean images of task-related ⌬rCBF for each individual were linearly regressed with motor impairment scores. Motor recovery was correlated with longitudinal ⌬rCBF images. Results-Patients (7 males; 72.0Ϯ9.8 years) demonstrated a wide range of impairment severity and variable recovery.Upper-limb motor function was linearly correlated with task-related ⌬rCBF. Importantly, sites of correlated ⌬rCBF differed over time. Subacutely correlated ⌬rCBF was observed in supplementary motor area (SMA), bilateral cingulate, and contralesional insula with a small area in ipsilesional primary sensorimotor cortex (SM1). Conversely, at the 6-month study, correlated ⌬rCBF was primarily in ipsilesional SM1, extending to the cingulate gyrus. Better motor recovery was correlated with reduction in contralesional activity and increase in ipsilesional SM1. Conclusions-Upper-limb
