Coin-rotation task (CRT), a measure of rapid, coordinated finger movements, was devised as a convenient, easily administered bedside test of motor dexterity; however, very little psychometric data exist regarding this task. The current project was undertaken to (a) provide preliminary normative data, (b) examine the convergent and discriminant validity of the task when compared with other stand...

background: noise is defined as unwanted or meaningless sound that apart from auditory adverse health effects may distract attention from cues that are important for task performance. human performance is influenced by many job-related factors and workplace conditions including noise level. objective: to study the effect of noise on human performance. methods: the participants included 40 healt...

[Purpose] The purpose of this study was to investigate the difference in task performance, grip and pinch strength, and dexterity with and without cock-up splints, which are widely used in occupational therapy practice. [Methods] Twenty-three participants performed Jebsen-Taylor hand function test and grooved pegboard for task performance and dexterity. The power grip and pinch strength was mea...

OBJECTIVE To study hand impairments and their relationship with manual ability in children with cerebral palsy. DESIGN Cross-sectional survey. PATIENTS A total of 101 children with cerebral palsy (mean age 10 years, age range 6-15 years) were assessed. METHODS Three motor and 3 sensory impairments were measured on both hands. Motor impairments included grip strength (Jamar dynamometer), g...

Although some recent studies concluded that dexterity is not a reliable predictor of performance in preclinical laboratory courses in dentistry, they could not disprove earlier findings which confirmed the worth of manual dexterity tests in dental admission. We developed a wire bending test (HAM-Man) which was administered during dental freshmen's first week in 2008, 2009, and 2010. The purpose...

Background Trigger finger (TF) is a common hand pathology frequently encountered in hand clinics. Occupational therapists predominantly assess TF symptoms as opposed to using standardized hand functioning assessments. The purpose of this study was to assess the construct validity of dexterity and grip strength assessments for clients with TF. Method Sixty-three participants with TF and 66 hea...

The All-Terrain Biped (ATB) robot is an unmanned ground vehicle with arms, legs and wheels designed to drive, crawl, walk and manipulate objects for inspection and explosive ordnance disposal tasks. This paper summarizes on-going development of the ATB platform. Control technology for semi-autonomous legged mobility and dual-arm dexterity is described as well as preliminary simulation and hardw...

background: the objectives of this study were to compare manual dexterity (gross and fine) and coordination performance of the ipsilateral upper extremity of the right hemisphere stroke patients with the same side of a healthy group, and to determine the relationship of ipsilateral upper extremity dexterity and disability. methods: in a non-randomized analytical study, 30 individuals with a uni...

HYPOTHESIS Objective assessment of surgical skill has recently been shown to be possible through the use of dexterity-based and video analysis systems. The aim of this study was to synchronize these 2 modalities to produce a comprehensive surgical assessment tool. DESIGN The Imperial College Surgical Assessment Device is a dexterity-based motion analysis device that has been developed in the ...
