BACKGROUND Although there has been extensive research about the kinematics of the neck, arm, and wrist during computer keyboarding, there is almost no information concerning the kinematics of the fingers, thumbs, and hands. The purpose of this descriptive study was to establish normative values of the kinematics of the fingers and hands during computer(More)
The growth of computer keyboard use in the workplace is believed to be one important determinant of the increased prevalence of work-related musculoskeletal disorders of the upper extremity (MSD-UE). One possible contributing factor to the development of MSD-UE is the flat standard keyboard, which places the forearm and wrist in biomechanically awkward(More)
A marker-based kinematic hand model to quantify finger postures was developed and compared to manual goniometric measurements. The model was implemented with data collected from static postures of five subjects. The metacarpal phalangeal (MCP) and proximal interphalangeal (PIP) joints were positioned in flexion of approximately 30, 60, and 90 degrees for 5(More)
OBJECTIVE The objective was to test the accuracy of using remote methods (tele-ergonomics) to identify potential mismatches between workers and their computer workstations. BACKGROUND Remote access to ergonomic assessments and interventions using two-way interactive communications, tele-ergonomics, increases the ability to deliver computer ergonomic(More)
OBJECTIVE To compare grip and pinch strength of individuals with carpal tunnel syndrome (CTS) to normative values before and after a combined splint/stretching intervention. METHODS Data collected on grip and pinch strength on 124 subjects with CTS were compared to age- and sex-matched normative data. RESULTS In general, our sample had significantly(More)
OBJECTIVE We described the frequency and distribution of keyboard users' potentially risky postural behaviors. METHOD Forty-three participants' keyboard postural behaviors were rated with the Keyboard-Personal Computer Style instrument (Baker & Redfern, 2005). The frequency and distribution of keyboard postural behaviors and the associations and(More)
