A. Bhattacharya et al., Development and evaluation of a microprocessor-based ergonomic dosimeter for evaluating carpentry tasks, APPL ERGON, 30(6), 1999, pp. 543-553
This portable and self-contained lightweight microprocessor based Ergonomic
Dosimeter is designed to collect continuously postural angles of the torso
and the upper arm in the sagittal plane and the number of kneeling activit
ies. Up to 4 h of task performance data can be stored in a non-volatile mem
ory of the dosimeter, which can then be downloaded to a lap-top computer. T
he portable dosimeter was tested for test-retest reliability, compared with
posture data obtained with a computer-based video analysis system and eval
uated at a carpenter's apprentices school and at a construction site. The d
osimeter was shown to be suitable for collecting posture and kneeling data
for a prolonged period at construction sites. (C) 1999 Elsevier Science Ltd
