“…Arm function in persons with neurological dysfunction is also routinely evaluated using ordinal scales such as the Fugl-Meyer assessment [14,15]. The finger-to-nose task is part of the Fugl-Meyer assessment, and it aims to evaluate coordination and speed by measuring and comparing, for instance, total performance time between the affected and non-affected arm [16]. To individualize the rehabilitation program and track changes in a movement deficit over time, it is important to have other outcome measures apart from performance time that describes the quality of the movement.…”

Ordinal scales with low resolution are used to assess arm function in clinic. These scales may be improved by adding objective kinematic measures. The aim was to analyze within-subject, inter-rater and overall reliability (i.e., including within-subject and inter-rater reliability) and check the system’s validity of kinematic measures from inertial sensors for two such protocols on one person. Twenty healthy volunteers repeatedly performed two tasks, finger-to-nose and drinking, during two test sessions with two different raters. Five inertial sensors, on the forearms, upper arms and xiphoid process were used. Comparisons against an optical camera system evaluated the measurement validity. Cycle time, range of motion (ROM) in shoulder and elbow were calculated. Bland–Altman plots and linear mixed models including the generalizability (G) coefficient evaluated the reliability of the measures. Within-subject reliability was good to excellent in both tests (G = 0.80–0.97) and may serve as a baseline when assessing upper extremities in future patient groups. Overall reliability was acceptable to excellent (G = 0.77–0.94) for all parameters except elbow axial rotation in finger-to-nose task and both elbow axial rotation and flexion/extension in drinking task, mainly due to poor inter-rater reliability in these parameters. The low to good reliability for elbow ROM probably relates to high within-subject variability. The sensors provided good to excellent measures of cycle time and shoulder ROM in non-disabled individuals and thus have the potential to improve today’s assessment of arm function.

“…In the spirit of the neurobehavioral examination, cortical signs can be derived from basic cerebellar tasks. Bergeron et al (2017) described two "signs" that patients with different types of dementia tend to make on the fingertonose test: (a) The "second finger syndrome" describes the patient who has mastered the task with one hand seemingly not knowing what to do when asked to perform the task with the other hand; and (b) the "distal pressure sign" refers to patients abnormally pushing on the examiner's finger, sometimes repetitively, while performing the task. These "signs" may reflect perseveration/stimulusbound behavior.…”

Over the last decade, our conceptualization of the examination has evolved. While we continue to emphasize the importance of con ducting a fluid, flexible, "informal" examination of brain function and behavior, we also recognize that qualitative assessment practices limit our ability to collect and share knowledge. This is, of course, one of the main historical motivations behind the conception of standardized neuropsychological testing.Since the publication of this chapter in the previous edition of this volume, the administration and interpretation of the exami nation in clinical practice have been refined. To avoid leaving poten tially valuable data "on the table," a clearer structure for the recording of neurobehavioral examination results has been developed. This shift in recording procedures has fostered research on unique neuro behavioral findings across disease populations and allowed for moni toring of neurobehavioral elements and reporting on patterns and syndromes. A flexible, observationdriven assessment approach is essential to the administration of the neurobehavioral examination.
