• Description:
  Many different typing styles exist in the workplace. The common typing styles are "two-finger" typing and touch-typing. Two-fingered typists use a maximum of two fingers per hand and often look at the keyboard. Touch-typists use all fingers of both hands and infrequently look at the keyboard. Ergonomic interventions lean towards "relaxed" touch typing methods; however, typing styles have not been quantified through biomechanical measures. This study aims to determine the effects of two different typing styles on posture, joint torque, and muscle activity in the upper extremity. These findings inform prevention efforts with reduced biomechanical loading, thus possibly reducing the risk of developing musculoskeletal disorders (MSDs). [Description provided by NIOSH]
