Implications: These findings indicate that subjects may not have been resting their arms on the chair armrests. It is possible that the chair armrests impede normal keyboard use and restrict a subjectís ability to reach all of the FAK keys. If this occurred in this study then some subjects may have been holding their arms above the armrest surface and thereby increasing load on the shoulder muscles.
