Wearable inertial sensor for motion analysis

Simple, fast and accurate measurement of any movement

G-WALK introduces a new approach to motion analysis: a special wireless sensor applied to the patient allows the assessment of their walking, running and jumping performance, and to conduct clinical tests such as the “Timed Up and Go” and “6-Minute Walk Test”.

These assessments, essential in the context of rehabilitation, help physicians and specialists evaluate the patient’s condition and quantify the efficacy of rehabilitation treatments or therapies.

G-WALK provides all the essential data for the clinical analysis of a patient in just a few seconds. The six included tests can be easily conducted and the results immediately compared with the normal ranges. The integrated protocols offer the possibility to perform complete and in-depth analyses.

Why choose it

A wearable motion analysis laboratory

G-WALK is worn by the patient thanks to a special belt. The patient is free to walk, run and jump without any obstructions. The sensor transmits the data via Bluetooth to the connected computer; at the end of the analysis, an automatic report is displayed with the parameters calculated during the test.
