G-WALK is a small inertial sensor that is used for the study of dysfunctional human movement. It relays 12 spatio-temporal parameters of gait and three planes of pelvic movement to a PC via Bluetooth connection.

There are six validated testing protocols to chose from which are very simple to perform. As G-WALK is designed to be a portable system, these tests can be completed in the clinic, in the lab, or out in the field.

Walk Test


Quantitative analysis for the performance of walking. The clinical evaluation of gait is fundamental for quantifying potential alterations induced by aging or neurological/orthopaedic pathologies. This test allows the clinician to demonstrate the functional benefits of a given treatment by assessing 12 spatio-temporal parameters, pelvic kinematics, and symmetry and propulsion indexes. The ease of test execution offers strong repeatability, allowing the clinician to modify the walking conditions and verify the effect of interventions and changes in real time.




Timed Up and Go Test


This is a balance evaluation test which is widely used to assess a patients risk of falling and functional mobility. From a seated position, the patient is required to stand up and walk 3 metres, turn around and return to the seated position. The report includes parameters such as the fluency of sitting and rising, acceleration, speed and angular analysis during rotation and walking pattern analysis.




Turn Test


This test is commonly used to assess the progression of degenerative neurological diseases such as Parkinson's. The patient is required to walk straight for 5 metres, make a 1 metre wide turn and walk back another 5 metres. The report provides a range of spatio-temporal parameters and compares pre and post turn gait parameters.




6 Minute Walk Test


This is an objective evaluation of residual functional ability in patients with neurological and muscular conditions during a 6 minute analysis of continuous walking over 30m. Strcitly linked with muscle fatigue, this test is ideal for accurately monitoring progress. Similarly to the standard walk test, the report includes a range of spatial-temporal parameters and pelvic kinematics, clearly displaing how these change over time.




Run Test


The run test is performed on a treadmill to identify any asymmetries or overloading during the running cycle, ideal for rehabilitation and athletic testing. This test provides vital feedback such as energy expenditure, pelvic kinematics, spatial-temporal parameters and symmetry indexes, allowing the clinician to evaluate technical aspects of the run to optimise technique.




Jump Tests


The are 7 types of assessment in the jump testing protocol, such as counter movement, squat and drop jumps. All tests check for kinetic and kinematic asymmetrical movement. The reports also feature useful global indexes such as elasticity, coordination, endurance and the Bosco index.





Not only is G-WALK an essential clinical tool with simplified reporting, it is also a powerful tool for research. Within each protocol, there is the option to export cleanly formatted raw data for analysis in Excel.

Below is just some of the quantitative data provided in the Walk Test report. In this instance, the clinician has assessed a stroke patient. You can clearly see the spatial-temporal asymmetries between the patients left and right side with the prolonged left stance phase. The symmetry index for pelvic tilt is very poor and there is a clear difference in pelvic obliquity throughout the gait cycle with the right side being elevated. Normative ranges are provided for each outcome measure e.g. the grey zones on the pelvic angle graphs. These results are vital to accurately monitor the patients rehabilitation. If you're not objectively assessing, then you're guessing!

Another useful feature of the G-WALK software is the ability to compare multiple tests. This allows you to quickly and accurately assess the effectiveness of different interventions, or monitor change over time.

The following graphs have been automatically generated from multiple walking assessments. In this case, a Parkinson's patient has been assessed every 6 months over a 2 year period. As their condition has deteriorated over time, we can clearly see the reduction in their speed, stride length and propulsion, whilst their cadence has gradually increased.
