T
he future of indus-
trial ergonomics
isn’t a person with
a clipboard check-
ing workers’ pos-
ture.
Warehouse op-
erators and manu-
facturers are now
testing wearable technology intended
to stave off injuries from repetitive
tasks like lifting boxes that can exact
a significant toll on workers’ bodies
over time.
Companies includingWalmartInc.
andToyota MotorCorp. are experi-
menting with sensors that identify
when workers engage in risky move-
ments—say, bending their backs with-
out squatting—and prompt them to
change their form in real time. The
devices also collect data that employ-
ers can use to assess how new equip-
ment, tasks or changes in production
volume affect worker safety.
Some firms also are testing light
but strong garments called exosuits
and more-flexible types of exoskele-
tons that help unload strain from the
lower back or shoulders but are de-
signed to be less cumbersome than
versions with rigid metal frames.
Overexertion in lifting or lowering
was one of the most common events
leading to occupational injuries
among laborers and freight and stock
employees in 2018, the most recent
year for which data were available,
according to the Bureau of Labor Sta-
tistics. The group had the third-high-
est rate of days away from work due
to nonfatal injury and illness at 264.1
per 10,000 full-time workers, trailing
only police and sheriff’s patrol offi-
cers and nursing assistants.
“We pay workers to use their bod-
ies for lifting, and so there is a cumu-
lative effect,” says Ed Napiorkowski,
general manager of safety, health and
environment for Australian whole-
salerMetcashLtd., which is conduct-
ing a six-month pilot of wearable sen-
sors from New York-based startup
StrongArm TechnologiesInc.
About 100 workers at Metcash gro-
cery, liquor and hardware distribution
facilities outside of Melbourne are
wearing StrongArm’s harness-
mounted devices on their chests as
they pick out cases of beer or hard-
ware items and drive pallet-laden
forklifts around the warehouse.
person’s body must have done to
make it move that way, then deter-
mines whether the motion is high
risk.
Direct observation isn’t as precise
because it can cause people to alter
their movements, Mr. Elhawary says.
Many ergonomics professionals “still
use tape measures,” he says, “so
bringing data to that is helpful.”
Donald Keim, Iron Mountain’s di-
rector of safety and health programs
and compliance in North America,
says on average the company has ex-
perienced a 45% reduction in at-risk
postures that could lead to injuries
across 18 markets in North America
over three years. He says the com-
pany is expanding the program to
more than 60 locations this year.
Toyota also is experimenting with
lightweight exoskeletons to reduce
upper-body strain among workers
performing repetitive overhead tasks
that can lead to shoulder injuries.
Companies such asU.S. Bionics
Inc., which does business as SuitX, are
rolling out increasingly flexible exo-
skeletons, including models that can
be worn under work jackets. Others
are taking the concept further with
strong but flexible textile-based sys-
tems called exosuits that feel more like
clothing.
An exosuit developed by Nashville,
Tenn.-basedHeroWearLLC uses elas-
tic bands that run across the back
and connect to the shoulders and
thighs to absorb some pressure from
lifting.
“The elastic band stretches as you
lean down, which reduces the
load....Because the elastic has stored
up energy in the band, it makes it
easier to pop back,” says Karl Zelik,
HeroWear’s chief scientific officer
and an assistant professor of mechan-
ical engineering at Vanderbilt Univer-
sity.
Workers can turn off the spring as-
sistance so the exosuit doesn’t ham-
per them in other tasks. HeroWear
says tests show the device reduces
peak force in back muscles by about
20% during lifting.
HeroWear has tested the exosuits
in pilots with a number of third-party
logistics providers and retailers, says
CEO Mark Harris. The system is set to
go on the market in March.

When it comes to putting new technology in
the workplace, the easiest part is often picking
the technology. The trickier part is introducing it
to employees.
If you do it wrong—and even if you have the
best of intentions—employees may end up feel-
ing alienated by the change and reject it, intro-
ducing a whole new set of problems, says Kevin
Craig, an assistant professor in the information-
systems and statistics department at Baruch
College’s Zicklin School of Business.
Here’s a look at some best practices when it
comes to changing technologies in the office.
Know the workflow.
Companies often rush into adopting a flashy
new technology that doesn’t end up meshing
well with their usual workflow, says David
Johnson, a principal analyst at Forrester Re-
search Inc. who advises companies on employee
experience and workplace productivity. This
happens, he says, when managers haven’t made
an effort to understand how employees do their
jobs on a granular level and exactly how the
new technology would help them do that work
more effectively. The result can be disgruntled
workers who either don’t use the tool or work
lesseffectively because of it.
Maintain a human touch.
Managers should consider how workers will re-
act to new technology emotionally and try to
relate to those feelings, Mr. Johnson says. There
are a number of concerns workers have as new
technology encroaches on the workplace, includ-
ing the fear that new tools may cost them their
jobs. There are also the day-to-day frustrations
associated with adjusting to new technologies,
which take time to learn.
Some employees may require extra guidance
or attention, Mr. Johnson says. Introducing a
new technology is an opportunity for managers
to demonstrate their ability to be supportive of
employees as individuals, he says.
Start small.
As a general rule, managers should try not to
roll out a new technology to every employee at
the same time, says Gerald Kane, a professor of
information systems at Boston College’s Carroll
School of Management. At any company, there
will be some workers who are more interested
than others in learning how to use new tools,
so it’s important to seek out a “coalition of the
willing,” and introduce changes to this group
first, Prof. Kane says.
Prof. Kane recommends trial periods of six or
eight weeks to implement small changes with
measurable results, which companies can learn
from and build on.
Have patience.
New technology also can take longer than ex-
pected to bring about performance improve-
ments. Indeed, research suggests that compa-
nies may see a dip in productivity after a new
technology is introduced, Prof. Kane says.
On average, it can take about six months be-
fore productivity goes up, he says, though it
may be less for simpler technologies.
Be transparent.
WorkTango, anemployee-feedback software
business, recently rolled out an organization-
wide change, switching from one suite of office
software to another, says Rob Catalano, the
company’s co-founder. The reason, he says, was
to strengthen WorkTango’s information secu-
rity.
When the launch came, Mr. Catalano assumed
it would be easy for employees to switch sys-
tems for simple tasks like email, file sharing and
internal communications. But because the lead-
ership team failed to provide context for the
switch, employees were initially confused by the
purpose of the new interface and frustrated
that common tasks were taking much longer
than before.
When management provided an explanation
for the change, there was broad acceptance, Mr.
Catalano says. The lesson, he says, is that it is
important to maintain clear communication
whenever new technologies are introduced.
Expect the unexpected.
It’s difficult to predict the problems that will
arise when a new technology goes live, says
Lynn Wu, an assistant professor of operations,
information and decisions at the Wharton
School of the University of Pennsylvania.
Prof. Wu says she helped a large consulting
organization roll out a digital collaboration tool
designed to make it easier for employees to ac-
cess experts across the firm. The expectation
was that certain employees on the firm’s pe-
riphery, with little access to the information
those experts could provide, would benefit.
The tool helped improve productivity over
time, and the service was particularly beneficial
for some women and new employees, Prof. Wu
says. But it also gave a leg up to those in the
company who already were well connected be-
cause it allowed them to extend their networks.
The effect was to reinforce the status quo, says
Prof. Wu. Companies should be on the lookout
for unexpected consequences once new tech-
nology is in place, Prof. Wu says.

workers to keep their backs straight

are using the data to assess riskier

“It’s not about productivity or pick
rates or any of that,” Mr. Napi-
orkowski says. “It’s about reducing
the chance of people getting hurt.”
Retail giant Walmart is running a
pilot of the StrongArm device at
about eight distribution centers to
see if it “will help our supply-chain
associates work safer in our build-
ings,” a spokesman says. At auto
maker Toyota, meanwhile, managers
used data collected by StrongArm
sensors during a trial late last year at
an Indiana plant to assess individual
differences in movement patterns and
how the order in which tasks are per-
formed might affect safety.
Sensor makers say their devices
aren’t meant to be used to penalize
workers or to track information be-
yond the ergonomic data.
“The device doesn’t have a GPS, it
doesn’t have a camera, it doesn’t have
a microphone,” says Haytham Elha-
wary, co-founder and chief executive
ofOne Million MetricsCorp., a New
York startup that does business as Ki-
netic and whose pager-like sensors
clip on to workers’ belts to measure
their body mechanics. “We really in-
