Study of the loading of the hand during hand tool operation
Measurement and prediction of the loading of the hand is important for developing functional biomechanical models and for designing ergonomical tools, work equipment and manual handling activities. The loading of the hand was investigated in this study by focussing on the following objectives: (1) …

Ergonomic evaluation of shoulder muscle activation during light weight hand tool exertion task
… the effect of shoulder muscle activation during hand exertion tasks using a light weight hand tool by working individuals. Electromyography (EMG) of trapezius, supraspinatus, triceps, and pectoralis major was conducted for 45 , 0 and -45 arm angles, for three different reaches i.e. normal, …

A Comprehensive Methodology for Assessing Biomechanical Risks Associated with Hand Tool Use: Applied to Laparoscopic Surgical Instruments
… risk factors associated with surgical hand tools had never been performed. Utilizing an opto-electronic motion capture system meant the exact surgeon posture was recorded during simulated surgical tasks. Electromyography was used to evaluate muscle recruitment and workload for small …

The effect of handle characteristics of a hammer stapler on biomechanical and physiological response
… and prolonged use of an improperly designed hand tool not only affects productivity but may also cause painful symptoms which, if left untreated, can develop into chronic musculoskeletal disorders (MSDs). This study was undertaken to assess the effects of ergonomic guidelines related to grip …

Isometric forces transmitted by the digits: data collection using a standardized protocol
… would prove particularly useful in areas such as hand-tool and control design, and also in medical evaluation. A standardized protocol is necessary if a sound, useful data base is to be built. This study developed such a protocol and data were collected using the defined protocol. The study also …

An Evaluation of Fatigue and Performance Changes During Intermittent Overhead Work
… levels of duty cycles, two work heights, and two hand positions). Four dependent measures based on endurance, subjective, objective, and physiological fatigue were used to quantify shoulder fatigue and were collected during the experiment. An overhead work task required participants to use a hand …

Analysis of an Anti-vibration Glove for Vibration Suppression of a Steering Wheel
Exposure to severe levels of hand-arm vibration can lead to hand-arm vibration syndrome. Towards curbing the development of hand-arm vibration syndrome, studies have shown that anti-vibration gloves effectively reduce the transmission of unwanted vibration from vibrating equipment to the human …

Determining Upper Extremity Posture Using a Simplified Marker Configuration for Biomechanical Risk Evaluation during Tool Use
… to data pertaining to laparoscopic surgical hand tool use. The biomechanical risk exposure of the tasks was quantified from the postural results using a threshold technique and a novel approach to the Rapid Upper Limb Assessment.</p>

The Narrative Subject and Place
… I utilize the inconspicuity of the ready-to-hand tool in Heidegger's Being and Time. However, I argue that to remain hidden is not necessarily the fate of place. I endeavor to exhibit the ways in which place is (and can be) self-consciously experienced. Finally, to demonstrate the ways in …

Evaluación comparativa de factores de preferencia uso de una herramienta de corte para floricultura con un nuevo diseño, versus la herramienta tradicional, estudio piloto
Colombia es uno de los principales productores de flores y rosas a nivel mundial y a través de los años ha presentado diversos problemas en la actividad industrial que permite la recolección de rosas. La cosecha y alistamiento del producto se realiza mediante actividades principalmente manuales. El …
