Microgate Optogate - Sprint and Gait Test

Version 1.9 Page 64 of 170
4.2.2.4 SPRINT AND GAIT TEST
Main Parameters
 Start type: indicates if the start of the test must take place with a ‘status change’ (i.e.
entering or exiting the bars) or with an ‘external impulse’ coming from the jack sockets
 Start: indicates if at the beginning of the test the patient must be ‘inside the area’ of the bars
or ‘outside the area’
 Staring foot: if known, the foot with which the test starts (“right” or “left”) can be indicated,
otherwise leave as “not defined”
 Stop type: indicates how the end of the test must be interpreted, (i.e. as ‘External impulse’
like a photocell at the end of the lane) or as ‘timeout’ (the number of milliseconds of Test
timeout can be customized in Utility – Basic Settings)
 Finish: for the Stop type = ‘Timeout’ it is necessary to specify if, at the end of the test, the
patient must be ‘inside the area’ of the bars or ‘outside the area’
 Test Length: appears only if Stop type = ‘End of Time’ and specifies how many
minutes:seconds the test must last (from 00:01 to 09:59)
 Number of intermediate times: indicates how many intermediate times are inserted
between the start and the stop (0 to 99)
 Template: see chap. 4.2.2.1.1
Secondary Parameters
 Minimum contact time [ms]: see above
 Minimum flight time [ms]: see above
 Maximum flight time [ms]: see above
 External signal hold off [ms]: is the hold off time between two consecutive external signals.
Caution has to be applied for this value, because it may depend on the type of test being
carried out.
 Entry point: allows you to indicate if the entry point of the Sprint/Gait test is on the ‘interface
side’ (drum) or the ‘opposite side’. If ‘automatic’ is chosen, OptoGait automatically calculates
the direction, considering the LED nearest the centre of the foot as the beginning of the LEDs.
 Step length calculation: allows you to choose whether to calculate step length as the
distance between the tips of two following feet or as the distance between the heels of two
following feet (see also Figure Figure 99).
 Minimum gap between feet [cm]: is the minimum gap between the tiptoe of one foot and
the heel of the next foot.
 Minimum foot length [cm]: is the minimum foot length in centimetres (or inches), used to
filter possible incorrect acquisitions.
 Split 1 or 2 at distance [cm]: insert at how many cm from the start the first or second split
time will be taken; leave 0 to disable split times.
