1INTRODUCTION
OptoJump Next is an innovative system of analysis and measurement that brings a new philosophy
of performance assessment and optimization to the world of competitive sport. By acquiring the
fundamental parameters that characterize the level of an individual’s performance and physical
condition, OptoJump Next allows coaches, trainers and researchers to constantly test and monitor
their athletes. This makes it possible to ascertain the abilities or physical fitness of an athlete in a
simple and instantaneous way, creating even over a period of time a database that allows to
compare values for that athlete or different athletes (even at a distance of months or years).
Quick Start: Online Video Tutorial
For a brief introduction to the software for OptoJump Next, we strongly recommend you watch the
introductory webcast available on the official site:
http://www.optojump.com/support/software-tutorial.aspx
The software modules will be illustrated in about ten minutes. After watching it, you will be able to
perform the most common operations, which can be summarized as follows:
Graphic and surfing interface
Checking of general parameters
Checking of status of bars and webcams
Insertion of athletes’ data
Performance of tests
Viewing results
Comparison of tests and statistics
Printing and exporting of data to other programs
Figure 1 –Webcast Tutorial

Version 1.10 Page 8 of 203
1.1 SINGLE METER
In this configuration OptoJump Next allows already to carry out various test types:
1.1.1 JUMP TEST
A series of exercises (squat jump, counter movement jump, drop jump, continuous jumps, jumps on
one leg, etc.) and protocols ('Drift' for dynamic stability, '5 Dot Drill' for reactivity and endurance,
'Single Leg Three Hops' to verify the bending capacity and stability of the knee) are pre-configured.
At the same time, the user can easily create customized tests or protocols.
1.1.2 TAPPING/FREQUENCY TEST
This type of test is ideal for exercises where separate results are required for the left and right foot
(e.g. tapping/frequency test, side movement, walking on the spot, etc.)
1.1.3 REACTION TEST
This test detects the time between one optical/acoustic impulse and the patient's movement. It can
be used to measure simple reactions or more complex movements

Version 1.10 Page 9 of 203
1.2 SINGLE METER ON TREADMILL
1.2.1 GAIT ANALYSIS,RUN ANALYSIS
Positioned on the side bars of a treadmill, OptoJump Next becomes a real portable lab for small
spaces and with reduced costs. The system is compatible with the wide majority of treadmills and
no synchronization is necessary to start and carry out a test.

Version 1.10 Page 10 of 203
1.3 THE MODULAR SYSTEM
In this configuration, OptoJump Next allows to carry out:
1.3.1 GAIT TEST
Gait tests can consist of simple exercises (moving from A to B), but also of more complex ones, such
as 'roundtrip' or walking backwards. They can be more complex, if needed, adding obstacles (e.g.
plastic cones) or actions to be carried out between the various gait phases (sitting down and getting
up before coming back, for example) or simultaneously.
1.3.2 RUNNING TEST
Running tests, just like gait tests, can be carried out either starting from a stand or running, to
analyze the various phases, how the incremental weariness acts on the patient at each round
installing the system on a track, measuring the time of a change of direction and the following
acceleration, and so on…
Thanks to the practical and innovative assembling system using caps, the modular system is
assembled in a few minutes and does not require cables to connect the bars or further net adapters.
The length goes from a minimum of 2 meters to a maximum of more than 100 meters.

Version 1.10 Page 11 of 203
1.4 THE TWO-DIMENSIONAL SYSTEM
Starting from version 1.8 of the OptoJump Next software it is possible to use a particular bar
configuration for obtaining a two-dimensional measurement area. To the classic bars (which we will
call X) more bars (Y) can be added to form a rectangle.
MAX 6 mt. (Eg. 5mt + 0,5mt. x 2 of space)
MAX 6 mt.
TX bar(s)
RX bars
TX bars
X
Y
The regular closing Y TX bar is usually a bar WITHOUT interface drum. Updating the firmware of the
TX bar with drum (already included with all articles having a serial number higher than 00500) this
last hardware type can also be used. Therefore with a 5-meter modular system it is for example
possible to use the complete hardware building a 4-meter-long linear gait system. For serial
numbers lower than 00500 it is possible to ship the bar to Microgate or a distributor and receive a
free update (shipping costs for sending and receiving are excluded). It is also possible to buy one or
more additional single TX bars.

Version 1.10 Page 12 of 203
If using a Y-bar with drum, make sure that the power supply is SWITCHED OFF (power off).

The bars situated on the perpendicular sides are connected using a variable-length cable (eg.
$CAB155, 1.5m long); this allows to distance the actual measurement area (the rectangle formed
by the regular bars and highlighted in gray in the following picture) of the Y bars; this area allows
the patient to leave the test area without having to jump over the bars or, more frequently, turn
around by 180° and go back. In fact, the software allows to carry out an undefined number of
back/forth courses recording a sufficient number of steps also in case of linear systems of only a few
meters.

Version 1.10 Page 13 of 203
1.5 THE GYKO INERTIAL SYSTEM
Gyko is a new tool, developed by Microgate, which enables obtaining information on the kinematics
of any body segment while making a movement.
Gyko contains the latest generation components that are used for making accurate and repeatable
measurements of acceleration, angular velocity and magnetic field in three dimensions.
3D accelerometer, to measure the linear accelerations to which the device is subjected.
3D gyroscope, to measure the angular velocities of the device.
3D magnetometer, to measure the magnetic field to which the device is subjected.
Gyko is able to provide the measured data up to 1000 times per second guaranteeing an extremely
high temporal resolution of the data. The data can be transmitted to the PC via a Bluetooth
connection or be stored on a MicroSD card.
From the measured data, through advanced software algorithms, it is possible to describe the
kinematics of the body segment to which Gyko is fastened so as to provide the user with summary
information about the quality of the analyzed movement.
Gyko can be used in combination with the OptoGait systems or independently.

Version 1.10 Page 14 of 203
1.5.1 GYKO TO ANALYZE WALKING,RUNNING AND MARCHING IN PLACE
Gait analysis is one of the most widely used methods to determine any disorders of the nervous
and/or musculoskeletal system. With OptoGait you can estimate the space-time parameters of the
gait and isolate individual phases of the step, then accurately describe the behaviour of the lower
body.
Gyko, placed in the area beneath the shoulder blade by using a special bib with a comfortable 3-
button fastening, enables naturally integrating the information measured on the ground with the
kinematics of the trunk in order to provide accurate information on the stability and coordination
of the upper body.
The movement of the trunk is analyzed in each phase of the step and, through advanced algorithms,
specific parameters of the analyzed test are estimated such as:
Antero-posterior and medio-lateral imbalance.
Main directions and breadth of the movement of the trunk.
Upper Phase Coordination Index (UPCI) that describes coordination in the rotation of the
trunk.
Phase difference between the lower body and the upper body.
RMS, Harmonic Ratio and Harmonicity index describing gait stability.
For details on the various columns see Sect. 0

Version 1.10 Page 15 of 203
1.5.1.1 DYNAMIC STABILITY
In addition to graphics for Step, Stride, flight/contact times, etc. with Gyko there is another one
called Dynamic Stability that can be activated from the legend on the left.
The graphic is an ellipse whose size represents:
how far the trunk rotates along the Antero-Posterior (AP) and Medio-Lateral (ML)
directions; the larger the area of the ellipse the more the trunk rotates.
in which direction the movement is prevalent. If the ellipse is stretched towards AP or ML
the movement of the trunk is prevalent in that direction.
The two horizontal and vertical bars below and to the right of the ellipse represent respectively the
offset of the ML/AP movement. The green/orange/red colour depends on the Bad and Warning
thresholds set in the Configuration panel (Area Threshold affects the colours of the ellipse and the
shades above for the gauges)
Set the Mode to "Dynamic Stability", the number of data on which to calculate the averages and the
two pairs of thresholds (the first pair for the two gauges and the second pair for the ellipse).

Version 1.10 Page 16 of 203
1.5.2 GYKO FOR JUMP ANALYSIS
Using field tests and in particular vertical jump analysis has always been a widely used method for
evaluating lower limb muscle strength. OptoGait is the instrument used to measure and objectify
the main features of a jump such as flight and contact time.
Gyko placed near the centre of mass with a special belt enables enriching the temporal data with a
variety of information regarding the dynamics of the jump. It is then possible to measure lower limb
strength directly and, using appropriate algorithms, accurately and repeatably provide data relating
both to the eccentric loading phase and to the concentric thrust phase.
The movement of the trunk during the flight and contact phase is analyzed and provides, among
other things, the following additional parameters (for all the others see Sect. 5.1.2.1):
Eccentric and concentric work and duration.
Force, Velocity and Maximum Power.
Rate of Force Development and Landing Rate.

Version 1.10 Page 17 of 203
1.5.3 GYKO FOR POSTURE ANALYSIS
Postural analysis is frequently used to evaluate the stability and balance of a quiet standing subject.
Gyko, placed on the trunk or at the level of the centre of mass, provides important information
about the body sway of the subject and through appropriate protocols it enables evaluating the
relative contribution made by the various components of the postural system (visual, proprioceptive
of different origin, labyrinthine, etc.).
Gyko lets you simply and quickly obtain the best known indexes concerning the projection of the
body's centre of gravity on the ground.
The main indexes returned are:
Projection length and area.
Projection travel speed.
Sway frequency
In this case the graphic is a "projection" showing all the movements (the red dot indicates the
position at the end of the test) and an overlay of the ellipse already seen in Sect. 1.5.1.1. To the right
there are two graphs, one for the antero-posterior movements and the other for the medio-lateral
movements with the time being the abscissa and the movement in mm the ordinate.
The test can be done with a custom "Static Test" (Sect. 5.1.6) or with the default Body Sway protocol
(Sect. 6.8) For all the details shown in the Summary Data please see Sect. 5.1.6

Version 1.10 Page 18 of 203
