History
Range of motion examinations are, at best,
subjective attempts at objective observations. No device to date, removes the variables
that make this exam somewhat unreliable. VROM attempts to bring a higher level of
reproducibility to the procedure through the use of digital image capture and computer display.
With VROM, the image of the person performing the maneuver is "frozen
in time" allowing more precise placement of the angle measuring tools, and in return,
a more precise examination.
Design Process
Much testing
went into VROM development to make sure that the results were
consistent and easily reproducible. While the program is easy to
use, the design process overcame many obstacles to develop an
accurate on-screen angle generator. In selecting the anatomical
landmarks used in the measuring process, we always compared the
results against inclinometers. We are confident that VROM is an
accurate tool for measuring ROM for any body part.
We have
included all the AMA Guidelines ROM tests in VROM and the
normal ROM findings.

Three Simple Steps to Using VROM
Using a digital camera or camcorder, computer and printer, it is now possible to
accurately measure ROM results from an on-screen image. The
procedure is quite simple. For every ROM exam, we provide
on-screen guides for the placement of anatomical landmark
markers. These markers will appear in the picture and are used to
instantly generate an accurate angle of motion.
Straight-forward,
intuitive analysis controls makes VROM easy for anyone to use. Special on screen tools
make generating precise angles of movement fast and easy AND reproducible.
The procedure
is really as simple as 1,2,3.
1. Capture image at end of ROM.
Image can be from a digital camera or camcorder jpg file, or copied from the
Windows clipboard.
2. Overlay angle tool.
Special tool movement arrows, zoom mode, and instant landmark
reference guides make using VROM a snap.
3. Generate Angle. The
program automatically compares the angle against the AMA Fourth
edition guidelines and reports back any deficit. An on-screen
graph is generated showing normal range, measured range, and
subjective level of pain.
Just like the AMA Guidlines
suggest, the program will record three trials and report back the
average of the three, and compare the average against the normal
range.
Storage
Options
VROM offers very flexible
storage solutions for results. The exam page(s) can be printed,
stored as images or stored as text results in a narrative format.
Previous exams can be recalled for comparison or printing.

Benefits of Using
VROM
The two biggest benefits of using VROM relate to the use of
image capture.
- You see a picture of the patient performing the exam. This
can become very important in PI/Work Comp cases.
- You see the angle measuring tool superimposed over the
patient's image for verification of the angle generated and the method used.
