Wearable system for the functional analysis of movement

G-WALK introduces a new approach to motion analysis: a special wireless sensor applied to the patient enables you to perform clinical tests such as the “Timed Up and Go” and the “6 Minutes Walking Test” in no time, it also supplies the most relevant parameters related to walking, running, and jumping.
This evaluation, which is essential in the ambit of rehabilitation, helps physicians and specialists to assess patient conditions and quantify the efficacy of treatments and/or rehabilitation therapies.

Fast, simple and accurate evaluation of motor problems

G-WALK can supply all the main data needed for the clinical analysis of a patient in a few seconds.
The six included tests can be easily performed and results compared right away with normal ranges.
The integrated protocols allow us to carry out complete and in-depth analyses of the main clinical tests:

Functional mobility, and fall risk assessment.

A powerhouse of technology

We have enclosed 4 inertial platforms and a GPS in a few cm3.
This structure improves accuracy in the acquisition process and drastically reduces error tolerance.
The system guarantees 8 hours operating autonomy and unlimited range of action thanks to its internal memory.

A wearable laboratory for analyses

The patient wears the G-WALK thanks to a specific belt. Here, the patient is completely free to walk, run and jump. The sensor sends all data to a computer connected via Bluetooth; at the end of each analysis an automatic report containing all the parameters recorded during the test, is displayed.
The parameters are the result of 5 years of research and have been validated by internationally recognized clinical centers.
