Invalid Times Management - Microgate Optogate User Manual

Gait Data Columns
 TExt. [s]: External time: available only for external impulse. This is the time between the
event (start/stop) of the impulse and the entry/exit into/from the OptoGait bars; it can also
comprise split times
 Stance phase [s | %]: The stance phase is the weight phase supporting phase of each gait
cycle. It begins with the contact of the heel and finishes with the set off of the tip of the same
foot. It is therefore the time between the first and the last contact of two consecutive
supports of the same foot. It is also presented as a percentage of the total gait cycle.
 Swing Phase [s | %]: The swing phase begins when the tip of the foot leaves the ground and
finishes with the contact of the heel. It is therefore the time between the last contact of the
first support of the foot and the first contact of the following support. It is expressed in
seconds (sec) and as a percentage of the gait cycle of the same foot. The swing time of one
foot corresponds to the single support time of the other foot.
 Single Sup. [s | %]: Single Support: This is the time between the last contact of the current
support and the first contact of the following support of the same foot (i.e., the time when
only one foot touches the ground). The single support corresponds to the swing time of the
opposite foot. It is expressed in seconds and as a percentage of the total gait cycle time.
 Total Double Sup [s | %]: This is the sum of two partial double supports, defined DS1 and
DS2 in Figure 118
 Step Time [s | %]: This is the time between the first contact of a foot and the first contact of
the opposite foot (it corresponds to the Step Time in the Run Data)
 Load Response [s | %]: This is the first Double Support Time (DS1 in Figure 118)
 Pre Swing [s | %]: This is the second Double Support Time (DS2 in Figure 118)
 Step Length [cm]: Step length (see definition above)
 Gait cycle [s]: This is the time between the first contact of two consecutive steps of the same
foot
 Stride Length [cm]: Stride length (see definition above)
 Speed [m/s]: Average speed of a single step (see Figure 111)
 Accel. [m/s
2
]: Speed variations of the two preceding steps (see Figure 112)
 Cadence [step/s]: Rhythm expressed in steps per second
 Total dist. [cm]: Progressive distance walked/run by a patient
 Contact Phase [s | %]: The time between the first contact of the heel and the complete
support of the foot; the percentage indicates the value with respect to the total contact time
 Foot Flat [s | %]: The time the foot completely touches the ground; the percentage indicates
the value with respect to the total contact time
 Propulsive phase [s | %]: The time between the lifting of the heel to the complete set off of
the tip of the foot; the percentage indicates the value with respect to the total contact time
