HALO: When Technology Meets the 40-Year-Old Goniometer

halo blog-1

From posture sensors and gait-correcting insoles to popular movement tracking devices like Fitbit, there have been a number of exciting advancements and trends in the physiotherapy industry.


Some devices, however, have received little innovation and their design remains relatively untouched by modern technology, such as the goniometer and the inclinometer.


Although there are a lot of different types of goniometers and inclinometers on the market, did you know that the manual goniometer design used by most Canadian medical professionals was designed over 40 years ago?


Because the reliability of goniometer/inclinometer readings depends on a number of factors, accuracy has been an ongoing issue for healthcare professionals. Simply put, the discrepancy between readings, whether it’s from one medical professional or between different medical professionals, can be significant.


Significant enough to look for a solution? Absolutely.


Get the New Standard and Lead the Way

Australian physiotherapist Hayley Warren recently introduced her new invention, an affordable solution that improves the accuracy of goniometer/inclinometer readings and stands as the next generation of clinical digital goniometers/inclinometers: HALO.


When I say digital goniometer/inclinometer, you’re probably thinking: “aren’t they really expensive and usually reserved for research?”


That used to be right, up until recently. Combining affordability and practicality – speed and accuracy – makes HALO ideal for clinical use.


HALO has been designed to bring greater accuracy by using visible laser arms that are long enough to measure the whole body part and can capture any joint range in less than 5 seconds and within 1o of accuracy!


By giving a clear digital reading that does not only rely on individual interpretation, this light-weight modern device can be used with one hand, leaving the other free to steady a body part if necessary. This way, you capture a more accurate, objective assessment of your patient’s R.O.M.


Physiotherapists have also reported that their patients feel a greater sense of trust when a HALO is being used to track their progress. By incorporating modern technology in your clinical devices, it can translate into a feeling of appreciation for a superior level of care by your patients.

How Does It Work?

The whole idea behind the pocket size design was not only to make it easy to use but also for therapists to be able to use it single-handedly. By using only one hand, you can use your free hand to help and secure your patient into position.


HALO doesn’t use arms or external components to gain measures of anatomical joints: it uses light-based markers that are activated on application and are projected along the full length of a limb to intersect with anatomical landmarks, which facilitates repeatable measurements.


The device also comes with built-in memory so you can store up to 5 measurements at a time.





HALO is the first goniometer that offers an affordable digital reading of measured anatomical angles to therapists. It ensures that there are no more erroneous therapist conclusions. Having precise R.O.M. measurements is vital for patients in order to provide them with the best medical care. HALO enables the practice of goniometry to be valid, accurate, reliable and repeatable.


Lead the way. Show your patients you care for their well-being!
