Introduction
Generally in developing countries, small scale industries employ
high percentage of workers as a substitute of automation. Such
industries contribute to major economic growth to these countries.
Usually, health and safety initiatives for workers are less considerate in
such industries [1]. Te understanding and control measures regarding
occupational hazards in developing countries is underprivileged [2].
Moreover, uneducated labour in these countries discourages to adapt
new technologies. And also local manufacturing industry’s workstation
are poorly designed. Most of the time workstations are not designed
according to the principles of ergonomics, as a result number of Work
Related Musculoskeletal Disorders (WMSDs) are generated among
workers. WMSD’s have a signifcant infuence on both labour and
industries all over the world [3]. WMSD’s have been recognised a most
important problem in European Union in terms health, capital and
productivity [4].
Manufacturing industry under study is highly labour intensive.
Most of the tasks are being performed manually by the workers. Fitting,
folding, pasting, stitching, trimming and cleaning tasks were studied.
A typical manufacturing process have highly repetitive tasks, which is
performed in sedentary position. Current working conditions in each
task results in poor trunk and upper extremities postures. Traditional
tools and poor work layout are also contributing to number of WMSD’s
among workers in these industries [5]. Te term musculoskeletal
disorders (MSDs) is used to refer to injuries and illness of diferent
body parts involved in working. Symptoms of WMSDs in manual
handling, prolonged standing and working in awkward posture are
very high irrespective of tasks [6].
In manual tasks like pasting, ftting/folding, cleaning, tools and
equipment such as hammers and scissors are extensively being used in
fashion design industry. Tese tools considered to have poor ergonomic
design. Tis study mainly focus manufacturing industry where cutting,
pasting, stitching, trimming etc. activities are performed. As shown
ftting and folding (Figure 1), pasting (Figure 2), stitching (Figure 3),
trimming (Figure 4) and cleaning (Figure 5) shown below. And most
of operations are done manually due to which this department is highly
labour intensive. For this study, we selected these departments, as we
observed more risk factor of WMSDs because majority of the tasks are
being performed using traditional hand tools (hammers, scissors etc.)
in sedentary posture. Hand tools being used are resulting in cumulative
trauma disorders among workers [7].
Te risk of WMSDs among workers with acceptable working
posture and enhanced productivity with the usage of minimum
resources. Current study is applicable on every industry where manual
operations are performed irrespective of its size and nature of job.
Tis study was steered to determine the prevalence of WMSD’s and
to suggest possible solution for risk reduction among fashion designing
industry. It is assumed that the result of this study could be suitable for
planning, designing and implementation of ergonomics principles at
fashion industry workplace to reduce WMSDs risks.
Methodology
Participants
Study population consisted of shoe and garment manufacturing
workers, from leading industries, of Pakistan. Tere were diferent
manufacturing lines with 5 diferent types of manual operations

Abstract
Results of study show that experience workers having more reported pain in upper body parts due to poor work
station design. This study is focused on measuring the Risks for WMSDs (Work related musculoskeletal disorders)
among workers in a manufacturing company, by applying ergonomic tools like QEC (quick exposure checklist),
RULA (rapid upper limb assessment) scores and Nordic questionnaire. A cross-sectional study was conducted
among workers aged between 18 to 45 years with a total number of 48 workers selected through random sampling
with in the duration of 12 weeks. Validated version of QEC, RULA score sheet and Nordic questionnaire was used
to measure the risk level and number of reported pain in body parts among workers. The results showed that the
mean score of QEC and RULA was 73.6 and 4.6 respectively. However, results showed that experienced workers
reported more pain in different body parts, indicating more chances of WMSDs among them. 79% workers of total
sample had reported pain in different parts of body according to Nordic questionnaire, out of which 86% workers had
pain in upper part and 14% had pain in lower part of the body that was also verifed from QEC and RULA score sheet.
