Ej. Hoekstra et al., ERGONOMIC, JOB TASK, AND PSYCHOSOCIAL RISK-FACTORS FOR WORK-RELATED MUSCULOSKELETAL DISORDERS AMONG TELESERVICE CENTER REPRESENTATIVES, International journal of human-computer interaction, 8(4), 1996, pp. 421-431
A cross-sectional study was conducted to evaluate the association betw
een work-related musculoskeletal disorders (WRMDs) and work conditions
, perceived exhaustion, job dissatisfaction, and job-stress issues at
two teleservice centers (TSCs). The study covered teleservice represen
tatives who respond to toll-free calls for assistance. The work involv
es a computer or manual search for information, and data entry using k
eyboards. One facility had upgraded the furniture at the workstations;
the other facility had not. A questionnaire survey among 114 teleserv
ice representatives and an ergonomic evaluation were conducted to dete
rmine WRMDs and their risk factors and perceived job stress. A high pr
evalence of symptoms of WRMDs was found at both TSCs. Suboptimal ergon
omic conditions were associated with neck, shoulder elbow, and back WR
MDs, as well as with increased job dissatisfaction. Perceived increase
d workload variability and lack of job control were associated with th
e occurrence of neck and back WRMDs, respectively. WRMDs were more fre
quently reported by teleservice representatives at the center with old
er furniture and suboptimal ergonomic conditions. WRMDs may be prevent
ed by improving ergonomic conditions at workstations and addressing wo
rk-organization elements.
