The Achilles Express
ultrasonometer is a compact, cost-effective solution for evaluating risk of osteoporotic
fracture.Its low precision error makes it suitable to monitor bone changes, such as those
associated with disease progression or response to therapy. Fracture Risk
Assessment
The Achilles Express measures the ultrasound properties of the heel which,
unlike the forearm or hand, is load-bearing and highly trabecular. Achilles Express
indicates risk of osteoporotic fracture comparably to femur and spine dual-energy x-ray
absorptiometry (DEXA). The Achilles Express is proven to indicate fracture risk in the key
group of women 45-75 years as well as older women.
Easy to Use and Interpret
The one-minute ultrasound test is simple to perform: a touch of the
built-in LCD screen is all it takes. Achilles Express automatically calculates the
patients STIFFNESS Index which is compared to young adult and age-matched references
to provide both a T-score and Z-score. These, together with other risk factors, assist
physicians in the diagnosis of osteoporosis.
Precision for Monitoring
The Achilles Express is sensitive to bone changes but not artifacts.
Ultrasonometers can be susceptible to variations in skin coupling, temperature, edema,
transducer position, and heel width. Achilles Express uses stationary transducers and
sophisticated convergence algorithms to minimize measurement errors. The Achilles Express
STIFFNESS Index has a precision of 2% in osteoporotic patients. Physicians can detect
small changes due to bone loss or response to therapy.
T-Scores
Achilles Express, like the Achilles+, provides T-scores comparable to spine
or femur BMD. The World Health Organization (WHO) defines fracture risk based on the
"T-score" for bone mineral density (BMD) measured by DEXA. The T-score is the
difference between the patient value and the average value in healthy young adults divided
by standard deviation.
Portability
The Achilles Express offers superior portability. This lightweight (22 pounds),
rugged ultrasonometer is easily transported or carried between offices using its built-in
handle.
The Achilles Express is perfect for the busy physicians office. It includes
an internal microcomputer with memory for 100 patient results, and a built-in printer. The
compact design occupies less than 2 square feet of office space allowing it to be stored
under a desk or in a closet when idle.
