The LiftTrainer… Measuring its Benefits
AN
AGGRESSIVE, INTERACTIVE TRAINING TECHNIQUE
TO PREVENT LOW BACK DISORDERS
Introduction
The LiftTrainer program evolved from
dissatisfaction with current risk and safety management programs
aimed at improving the lifting habits of manual materials
handling workers.
Reasons The LiftTrainer exists:
-
Traditional safety programs
don't allow employees to internalize concepts and adapt
their behavior
-
The presentation of techniques
are not effective in reducing stress on the spine
-
Traditional presentations do not
allow for measuring a behavioral change
-
Traditional presentations allow
employees to "skate" by because they know what is going to
be said
-
Every employee is different
and should be treaded as such
Our approach is to train employees in safe
lifting practices by focusing on lifting behaviors and the stress on the spine which
result from an individual's behavior. We then apply behavior modification techniques to
guide each person towards a lifting style that minimizes the stress on the spine without
reducing the employee's work effectiveness. At the core of our program is a product called
The LiftTrainer. This is an educational tool
that is based on biofeedback principals. The employees are "wired" with sensors
that track the back and upper body motion in a three dimensional space. This motion,
combined with the forces generated by the load handled, are used to compute the stress on
the spine in real time. The stress is communicated to the employee through a variable
pitch tone, where the pitch of the tone is determined by the instantaneous stress level.
Employees are individually coached while using The LiftTrainer in
lifting behaviors that minimize the tone's pitch and consequently the stress on the spine.
The program consists of five components:
1. Introductory meetings to announce the
program and give employees an overview of what will be happening.
2. The identification of self-reinforcing
teams.
3. Two training sessions for each employee
with The LiftTrainer
4. Remedial training sessions for those who
need it.
5. A quarterly refresher session for each
employee. These sessions provide a basis for monitoring skill retention and to identify
employees in need of additional training.
PROGRAM COMPONENTS
1. Introductory Meetings
Short meetings (15 minutes) will be held at
the beginning of the work shifts to introduce the training and briefly demonstrate The
LiftTrainer. This reduces considerably the time
required to explain the equipment to each individual at the start of a training session,
and therefore, allows the training session time to be used more effectively. The
self-reinforcing team concept will also be introduced.
2. Identification of self-reinforcing
teams.
Teams of 10 to 20 individuals will be
randomly selected from the list of employees at the beginning of the training. The purpose
of these teams is to have employees help one another with their lifting techniques. Each
team will be given different colored hats to designate team membership. The team showing
the best retention following the initial training will receive an award to be determined
by management and Lavender & Associates.
3.
Two training sessions for each
employee with The LiftTrainer
Each employee will participate in two 30
minute training sessions approximately 2 to 4 weeks apart. Sessions are conducted by a
"coach" who has been trained by Dr. Lavender of the Rush Presbyterian St. Lukes
Medical Center in the use of The LiftTrainer and
the training protocol.
Each session is initiated by
"wiring" the employee with the sensors from The LiftTrainer.
First a range of motion assessment will be performed. Using the
sensors from The LiftTrainer range of motion assessments are quick and
easy. These data will be used to identify deficiencies that the employee may wish to work
on with stretching exercises and to make to provide therapists a target recovery level in
the event of an injury. In essence, these data would provide documentation of an
employee's pre-injury condition.
During the three phase instructional
protocol the employee will then be asked to perform several repetitions of a lifting task
that is representative of his or her normal job tasks.
In the first phase, the employee will be
asked to demonstrate their "typical" lifting technique that they use everyday.
This first set of lifts provides baseline performance data whereby we can quantify the
spine stress generated by the existing lifting style. Immediately following the baseline
task the data will be displayed and explained by the coach so that the employee fully
understands what is being measured and evaluated.
In the second phase, or coaching phase, the
employee is then introduced to the feedback tone signaling the stress on his or her spine.
The employee is then taught to focus on the variable pitch tone, learn where the pitch
becomes highest, and learn how to lower the feedback tone's pitch, and consequently, lower
the stress on the spine. Following each bout of lifting the coach will graphically display
the peak stress on the employee's spine during each lift in the set. This data will be
used by the coach to guide the employee toward lifting behaviors that minimize the spine
stress. Data showing the duration of each lift is also displayed. This allows the employee
to develop lifting behaviors that maintains his or her work effectiveness.
The session then concludes with the
evaluation phase in which the employee performs the simulated work task one more time
without biofeedback or coaching. The average of the peak spine stresses from each lift in
this final set is then compared with the average of the peak spine stresses obtained in
the base line set (first phase). This comparison indicates which employees have
successfully modified their lifting behavior so as to reduce the stress on their spine
within the session.

The second session is conducted to
reinforce the lifting behaviors taught in the initial session and allow the employee
another opportunity to practice with The LiftTrainer. Most importantly
this session identifies who has retained the behaviors from the initial session and who
has not. Those who either do not show retention, or failed to show improvement in the
first session will be identified as candidates for remedial training.
It is recommended that the supervisory
staff participate in the training sessions with The LiftTrainer and
participate in each of the teams. This will enable them to reinforce the desired behaviors
on a daily basis as well as show management's commitment to the program.
4. Remedial training for those who need
it.
It is anticipated that some employees will
need additional training. This round of training is focused on those who, by our
measurements, need it most. Thus, your training dollars are directed at the employees that
are at greatest risk for a back injury. Decisions for remedial training will be based upon
performance improvements within the prior two sessions, and the retention between
sessions. Based on our pilot testing we anticipate no more than 25 percent of those
trained should require remedial training. It is possible that even some employees may
require a fourth session. We believe that using this "test-out" protocol ensures
that your workforce has learned the concepts and modified their lifting behavior.
5. Quarterly refresher sessions to
determine which team showed the highest retention.
Given that success of the training depends
on the learning of appropriate lifting behaviors and the retention of those behaviors,
additional training sessions will be conducted after 3 months to assess and reinforce long
term retention. Average retention will be compared among the self reinforcing teams to
determine which team will receive the program award.
REPORT
Sixty days following the completion of each
quarterly refresher session, an interim report will be prepared evaluating the outcome of
the program. It is expected that injury data will be made available throughout the period
and during this evaluation process. Ninety days after the conclusion of the program, a
final report will be submitted.
FACILITY REQUIREMENTS
A secured training area with approximate
dimensions of 20 feet by 20 feet. |
