Overview of The LiftTrainer...
What is The LiftTrainer?
The LiftTrainer
is a fresh new approach to lifting instruction that incorporates many of the concepts used
in behavioral modification and biofeedback conditioning. Unlike traditional back education
which has typically focused on teaching the concepts behind good lifting techniques, The
LiftTrainer focuses on and measures behavioral change. Essentially, The
LiftTrainer uses biofeedback principles and behavior modification
techniques, along with individualized coaching, to motivate and teach individuals lifting
techniques that will minimize the stress placed on their spine while performing normal
lifting activities.
How does
The LiftTrainer work?
Each employee trained with The LiftTrainer™ is "wired-up" with
sensors used to track their movements as lifts are performed. The
LiftTrainer™ software uses the movement data and box weight data to
instantaneously calculate the stress on the spine. The value of this
stress is used as the "biofeedback" signal in that it controls the pitch
of a tone heard by the trainee. The higher the instantaneous stress on the
spine, the higher the pitch of the tone will be. It should be emphasized
that the factors entering into this stress calculation go far beyond how
much someone is bent over. The computed stress takes into account the
three-dimensional lifting posture, the speed of the lifting motion, the
amount of weight lifted, and how quickly the load and body is accelerated.
In other words, the stress is determined using a full three-dimensional
dynamic analysis of the lifting task computed 144 times per second. So as
this stress changes throughout the lift, so does the pitch of the tone.
A
coach works with each employee in a one-on-one training session.
First, the coach directs the employee’s
attention to the relationship between his or her lifting behavior and the
pitch of the tone. Second, the coach guides the trainee towards lifting
behaviors that keeps the pitch of the tone, and the stress on the spine,
as low as possible. The coach is supported in this endeavor with
graphically presented data showing the peak spine stress from each of the
trainee’s lifts. Thus, progress can be monitored throughout a training
session.
How often
is The LiftTrainer used?
Each employee receives five training
sessions over a one-year period. The first two sessions occur within three to four weeks
of each other. In each session lifting tasks representative of the employees normal
work activities are performed.
Data from the first and last sets of lifts
are used to evaluate performance improvement and retention. Those who show poor retention
or little improvement in their spine stress levels may be scheduled for additional
"remedial" sessions. The remaining three sessions are scheduled at quarterly
intervals.
In summary,
