Abstract

Two-button computer mouse users may exhibit sustained, static finger lifting behaviours to prevent inadvertent activations by avoiding finger pressure on the buttons, which leads to prolonged, static finger extensor muscle loading. One hundred graduate students were observed during normal computer work ill a university computer facility to qualify and quantify the prevalence of lifted finger behaviours and extended finger postures, as well as wrist/forearm and grip behaviour, during specific mouse activities. The highest prevalences observed were 48% of the students lifted their middle finger during mouse drag activities, and 23% extended their middle finger while moving the mouse. In addition, 98%, of the students rested their wrist and forearm (77%) or wrist only (21%) on the workstation surface, and 97% had an extended wrist posture (15[degrees]-30[degrees]) when using the mouse. Potential applications of these findings include future computer input device designs to reduce finger lifting behaviour and exposures to risk factors of hand/forearm musculoskeletal pain. Keywords: Finger behaviour; Computer mouse use; Finger lifting prevalence

4. Remodelling of hand representation in adult cortex determined by timing of tactile stimulation

Author

Abstract

Serial induction of stimuli in the fingers changes the neuronal specificity and somatosensory maps of the hand surface in adult owl monkey, trained to respond to particular stimulus sequence events. Synchronous application of remodelling stimuli to the fingers causes their integration whereas, asynchronous induction of stimuli causes their segregation. A terminal electrophysiological neuronal response mapping analysis reveals that conditioned monkeys have multiple-digit receptive fields.

9. Finger tapping ability in healthy elderly and young adults

Author

Subjects
Aged -- Comparative analysis, Aged -- Physiological aspects, Fingers -- Physiological aspects, Human mechanics -- Research, Young adults -- Comparative analysis, Young adults -- Physiological aspects, Health, Sports and fitness
Abstract

The dynamic motor function of individual fingers between elderly and young adults using rapid single-finger and double-finger tapping are compared to gain insight into age-related changes in dynamic motor capacity of individual fingers. The decline in finger tapping ability in elderly adults observed to be less affected by their maximum force production capacities of the fingers as well as tactile sensitivities at the tips of the fingers.
