NARRATIVE REVIEW: This article is a narrative review of the psychometric properties (reliability and validity) and other characteristics (cost, time to administer, and year of publication) of commercially available manual and finger dexterity assessments used for adults in the United States. Complete research articles related to dexterity assessments were gathered from online database searches ...

This paper describes how to evaluate the performance of dexterity measures by investigating the properties of the inverse kinematic algorithms. These algorithms use redundancy to optimize the dexterity measure under the constraint of following a specified end-effector trajectory. To facilitate the investigation, a concept of the construint locus is proposed. The constraint locus is the loci of ...

Dexterity, defined as the skillful manipulation of the hands, is now amenable to physiological investigation. Two topics are discussed here: grasping (i.e., hand-object coupling) and bimanual coordination. Dexterity depends on powerful, distributed neural networks and is particularly vulnerable to brain lesions. A knowledge of physiological mechanisms is needed to deal with these neurological p...

Degenerative functional and neurocognitive disorders with limited manual dexterity are becoming more prevalent as life expectancy is improved. Although the use of a removable partial denture is widely accepted treatment modality, the clinician should recognize the indications and maintenance requirements of different designs for individual patients. The planning and limitations of such treatmen...

OBJECTIVE To assess initial efficacy and tolerability of a thumb opposition splint on manual dexterity, perceived upper limb functioning and occupational performance in patients with Charcot-Marie-Tooth disease. DESIGN One group pre-post design. PATIENTS AND METHODS Thirteen patients were provided with a neoprene opposition splint for their dominant hand. Manual dexterity (Sollerman hand fu...

OBJECTIVE The purpose of the study was to evaluate the feasibility and efficacy of robot-assisted hand rehabilitation in improving arm function abilities in sub-acute hemiplegic patients. DESIGN Randomized controlled pilot study. SETTING Inpatient rehabilitation centers. PARTICIPANTS Thirty hemiplegic stroke patients (Ashworth spasticity index <3) were recruited and randomly divided into ...

Two methods for determining dexterity of manipulator arms are presented. A numerical method is illustrated for determining all possible orientations of the end-effector of an open kinematic chain based upon a row-rank deficiency of the sub-Jacobian of the kinematic constraint equations. This numerical method has been adapted from a theory for determining the accessible output set for planar and...

This paper investigates how the latency in a mobile network affect the quality of a highly demanding and sensitive application running on it. The application chosen is a bilateral teleoperation with a haptic input device, meaning a remotely controlled robot with force feedback. The latency of the two a 3Gand 4G Network were measured and simulated in application. To examine how the latency affec...
