Gait analysis
LEGSys is a portable medical device based on wearable sensors for quick and objective assessment of gait, gait steadiness, and dynamic balance during walking. LEGSys includes software modules for administrating standard gait tests such as Timed Up & Go (TUG) and 6 Minute Walk Test (6MWT). During each test, LEGSys sensors accurately measure the kinematics of lower body to calculate a wide range of gait parameters.
Advanced algorithms automatically check, detect and correct possible human errors (e.g. sensor misplacement). In addition, BioSensics offers customized versions of LEGSys to enable assessment of endpoints such as foot drop and wrist kinematics during walking.
Spatio-temporal gait parameters
Step and stride length
Step and stride time
Stride velocity
Step and stride time and length variabilities (indicators of gait unsteadiness)
Shank, thigh, and knee range of motion (indicators of joint rigidity)
Center of mass sway in medial-lateral and anterior-posterior directions (indicators of dynamic balance during walking)
Gait initiation
Number of steps to achieve steady state walking
Distance required to achieve steady state walking
Spatio-temporal parameters of gait during gait initiation
Balance analysis
BalanSens is a portable medical device based on wearable sensors for quick and objective assessment of balance and postural sway. BalanSens includes software module for standard balance tests. BalanSens uses two motion sensors (one on the shin and one on the waist) to calculate over 17 measurements including:
Center of Mass (COM) motion
Anterior-Posterior motion
Medial-lateral motion
Ankle and hip angles
Sway velocity
Sway area
Reciprocal Compensatory Index (RCI)
