ERGONOMIC ASSESSMENT OF
WORKSTATION AND RULA ANALYSIS
OF EMPLOYEES AT JUMP TRADING
CENTER
Under the guidance of
-Dr. R. Pope-Ford

2. Introduction and Background
 Cumulative trauma disorders
(CTDs) are injuries of the
musculoskeletal and nervous
systems .
 caused by repetitive tasks,
forceful exertions, vibrations,
mechanical compression. CTDs
are also called as repetitive
motion disorders (RMDs).
 our study on CTDs ,is conducted
in JUMP trading simulation and
education center, Peoria.

3. JUMP TRADING SIMULATION
• Formed by the collaboration of OSF health care and university of Illinois
college of medicine
• Deals with the simulation education and as well as research programs.
• JUMP is having three types of workstation designs:
 Tree Arch design
 Fish Bowl design
 Open Island design
• The designs are distinguished based on the type of alignment of the work
stations, on the seating of the employees.
• initiated these three designs to check for the comfort of the employees

4. Objective:
To check for the
 Influence of the work station and work performed by the employee
causing CTDs.
 To control the risk factors in the work environment
Methodology:
To understand about the extent of CTDs in the employees we use,
 RULA (Rapid Upper Limb Assessment)
 McCauley- Bush Fuzzy Rating Scale for Evaluation of Cumulative
Trauma Disorder Risk

5. RISK FACTORS:
 Level of CTDs are found based on survey
conducted on different risk factors and the
risk factors are as follows
 Task-Related Risk Factors
 Personal Risks
 Organizational Risk Factors
 These risk factors are found by
interviewing employees and they are noted
based on their intensities.

6. CALCULATIONS
 Task-Related Risk:
R1 = F(T) = a1w1 + a2w2+ a3w3 + a4w4 + a5w5 + a6w6
 Personal Risk:
R2 = F(P) = b1x1+ b2x2+ b3x3+ b4x4 + b5x5 + b6x6
 Organizational Risk:
R3 = F(O) = c1y1 + c2y2 + c3y3 + c4y4 + c5y5 + c6y6
 The final calculations are calculated based on module risk for
comparison of the results of various employees
Z = d1R1 + d2R2 + d3R3

12. Categorization of aggregate numeric risk
levels
Numeric Risk Level Expected Amount of Risk Associated with Numeric Value
0.00 - 0.20 Minimal risk: Individual should not be experiencing any conditions that indicated musculoskeletal
irritation
0.21 - 0.40 Some risk: may be in the very early stages of
CTD development. Individual may experience irregular irritation but is not expected to experience
regular
musculoskeletal irritation
0.41 - 0.60 Average risk: Individual may experience minor musculoskeletal irritation on a regular but not excessive
irritation
0.61 - 0.80 High risk: Individual is expected to be experiencing regular minor or major
musculoskeletal irritation
0.81 - 1.00 Very high risk: Individual is expected to presently experience ongoing or regular musculoskeletal
irritation and/or medical correction for the condition

13. RULA
 RULA was developed to evaluate the exposure of individual workers
to ergonomic risk factors associated with upper extremity MSD.
 The RULA ergonomic assessment tool considers biomechanical and
postural load requirements of job tasks/demands on the neck, trunk
and upper extremities.
 A single page worksheet is used to evaluate required body posture,
force, and repetition.
 After the data for each region is collected and scored, tables on the
form are then used to compile the risk factor variables, generating a
single score that represents the level of MSD risk.

14.  No need for an advanced degree in ergonomics or expensive
equipment
 Score will be assigned for each of the body regions: upper arm, lower
arm, wrist, neck, trunk, and legs.

 Periodical breaks for the employees
 Posture foot stool
 Keep hydrated once in half an hour
 Sit up and stop slouching

Pain Description
Male vs Female
Female Male
 Female subjects are entitled to more pain when compared to male
subjects. This can be attributed to their comfort with the
workstation.

22. CONCLUSIONS:
 TREE ARCH configuration
 Regular interaction with ergonomist
 Important gears or accessories like Keyboard pad to comfort their
wrists, custom made chairs to support their lumbar system
 An eye protection screen to reduce any optical discomforts due to
long use of computers were suggested by the team

23. QUALITRICS:
 Qualtrics is a private
research software company.
 Qualtrics software enables users to
do many kinds of online data
collection[ and analysis including
market research, customer
satisfaction and loyalty, product
and concept testing, employee
evaluations and website feedback.
