Complete solution for
the evaluation of the
spatio-temporal gait
parameters
BTS G-Walk is the ideal solution for providing
accurate, reliable and objective outcome data
for analysis of a wide range of gait disorders.
BTS G-WALK consists of a wireless system
of inertial sensors that, when positioned
around the patient’s waist (on L5 vertebrae),
allows for an objective functional gait analysis
that provides accurate, objective and
quantitative data.
It is intuitive and easy to use, and does not
require extra subject preparation. Thorough
and informative reports are generated
automatically to be utilized as part of baseline
and follow-up rehabilitation programs, or for
orthotic and prosthetic interventions.
Spatio-temporal parameters analysis
The system calculates spatio-temporal gait
parameters that are a powerful and easyto-use tool for the functional evaluation of
neurological and orthopedic patients, allowing
for objective analysis of motor capabilities and
treatment results.
Pelvic kinematic analysis
Kinematic information provides for anteroposterior rotation, antiretroverion, and lateral
tilt of the pelvic girdle.
Comparison with normative data
Automatically generated reports provide
normative data for easy comparison with
acquired gait parameters. Comparison of
results provides visual, graphic and intuitive
understanding of changes in gait parameters.
Evaluation Test
BTS G-WALK includes WALK, a protocol
validated by the scientific community for the
analysis of the gait. 1
Other test protocols also available::
- TUG (Timed Up and Go)
- Free Test
- Turning
- Jump

Objective use of gait parameters allows for:
• Quantifying gait characteristics of hemiplegic patient
• Pre and post documentation of orthopedic surgical candidates
• Accurate and consistent baseline and follow up of patient progress
during recovery and rehabilitation
• Use in balance and falls prevention program
• Outcome measures which may assist in the reimbursement process

Parkinson ‘s disease
Spatio-temporal gait parameters are
indicators of rehabilitation treatment
efficacy, particularly pharmacological
interventions.
In fact it has been demonstrated in
literature how the spatial parameters
(such as the step length) are DOPAdependent, unlike the temporal
parameters (such as stance and swing
phase) that are DOPA-resistant. 2

Fall Risk Prevention
Differences in mean values of gait
parameters, such as speed, stride length
and double support time are associated
with falls risk. Short-term variability in
gait parameters, measured every three
months, can be a predictive factor in
falling.3
Orthopedics application
Gait assessment is an integral part of
orthopedic interventions in the lower
extremities. G-WALK can be used to
monitor compliance with treatment
protocol and maximize functional
recovery through the objective analysis
of treatment results.
