Effectiveness of an ergonomic keyboard for typists with work related upper extremity disorders: a follow-up study.

Objective: To investigate whether long-term use of an ergonomic keyboard was effective in reducing symptom severity and improving functional status for individuals who experience symptoms of work related upper extremity disorders (WRUED).

Participants: Twenty-nine symptomatic workers employed by a single company.

Methods: Participants were assessed after using an ergonomic keyboard for an average of 34 months.

The effect of alternate style keyboards on severity of symptoms and functional status of individuals with work related upper extremity disorders.

Unlabelled: There is evidence that performing job tasks involving repetition, vibration, sustained posture or forceful movement may contribute to symptoms of work related upper extremity disorders. Typing is one such activity; symptoms that develop as a result of this activity can affect performance of work, self-care and leisure occupations. Studies investigating the impact of ergonomic keyboards on symptom reduction are limited, and little research exists regarding the reduction of key activation force as an intervention.
