For ergonomic workstations, results of size
measurements of tables, chairs, and work areas are
shown in Table 1as values of 5

percentile. We compared anthropometric
parameters of 131 officers to ergonomic
workstations (sitting, 131 workstations).
Comparison of the mean height of tables (75.2 ±
1.1 cm) to the mean elbow height (69.5 ± 7.7 cm)
showed that the level of 75.6 % workstations were
significantly above the recommended level (below
or equal the elbow height) for each worker at p<
0.001. By self adjustment of workers, 72.5 % of
musculoskeletal pain cases reported inappropriate
table heights and 56.1 % of cases reported
inappropriate seat heights (Table 2). Results of the
comparison between the mean height of seats and
the popliteal height of participants were heightadjustable seat. The mean values of seat width,
depth and backrest height were significantly
different from hip breadth, buttock-popliteal
length, and sitting shoulder height of workers,
respectively (Table 1). However, these differences
indicated the dimension-adjustable to average
anthropometric characteristics of all workers by
following the guideline of Anthropometry [10] and
OSHA [14].
