G-WALK is a new approach to motion analysis: a special inertial sensor applied to the patient enables us to perform clinical tests such as the “Timed Up and Go” and the “6 Minutes Walking Test” and in no time, supplies the most relevant parameters related to walking running and jumping.
This data, which is essential in rehabilitation, helps physicians and specialists to assess patient’s condition and determine 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.
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:
Subject functional mobility, fall risk and balance evaluation.
Parameters
- Spatio-temporal parameters standing phase, sitting phase and rotations
- Trunk kinematics (flexion and/or extension angle)
Evaluation of exercise and functional residual capacity in pediatric and elderly subjects.
Parameters
- Total distance travelled
- General spatio-temporal parameters,
- Variation in spatio-temporal parameters during the 6 minutes walking,
- Pelvis kinematics.
Walking test on fixed or variable distance (10 meters walking test).
Parameters
- Spatio-temporal parameters
- General kinematic parameters
- Symmetry index,
- Propulsion index
- Pelvis kinematics.
Evaluation of movement alterations development due to neuro-degenerative diseases.
Parameters
- Spatio-temporal parameters (global and diversified for the outward phase, rotation and backward phase)
- General kinematic parameters divided by phases.
Evaluation of post-injury recovery level, spatio-temporal parameters and asymmetries analysis.
Parameters

- Spatio-temporal parameters variation during run,
- Symmetry index
- pelvis kinematics.
Sports performance monitoring.
Parameters

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 subject wears the G-WALK thanks to a specific belt. The subject 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. The test can be repeated several times with or without aids or orthotics, in order to check treatments effectiveness in real time.
