Page 8: Single Meter
1.1 S INGLE ETER In this configuration OptoJump Next allows already to carry out various test types: 1.1.1 J 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.
Page 9: Single Meter On Treadmill
NALYSIS NALYSIS 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.
Page 10: The Modular System
1.3 T ODULAR YSTEM In this configuration, OptoJump Next allows to carry out: 1.3.1 G 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.
Page 11: The Two-Dimensional System
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.
Page 12 If using a Y-bar with drum, make sure that the power supply is SWITCHED OFF (power off). Power RX bars Power TX bars 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;...
Page 13: The Gyko Inertial System
1.5 T NERTIAL 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.
Page 14: Gyko To Analyze Walking, Running And Marching In Place
1.5.1 G YKO 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.
Page 15: Dynamic Stability

Page 16: Gyko For Jump Analysis
1.5.2 G YKO 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.
Page 17: Gyko For Posture Analysis
1.5.3 G YKO 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.).
Page 18: Environmental Conditions And Disclaimers
1.6 E NVIRONMENTAL ONDITIONS AND ISCLAIMERS The system is intended only for indoor use and at a height of max. 2000 m a.s.l. Operating temperature 0°C ~ +35°C As of the manufacturer's specifications only the intended use is allowed The estimated product life cycle is of 20 years. Positioning of the bars on the ground To avoid interferences between the patient and the bars, we advise a distance of at least one meter between the bars and we advise to pay attention that bars don’t hinder the gait.
Page 19 Positioning of the bars on the treadmill The bars must be positioned at the sides of the treadmill so that the minimal security distance planned by the producer is obeyed.We advice to fix "L" stirrups outside the chassis. When mounting the bars on the treadmill ensure that vibrations caused by walking/running do not move or make the bars fall down or onto the mobile area.

Page 32 To recharge the battery, connect the adaptor plug to the dedicated socket on the drum. The TX RX bars can be recharged simultaneously using the dedicated cable that connects the second drum to the adaptor. Figure 25 - Adaptor and cable for second bar The connection cable is long enough to make it possible to keep the bars at a normal distance (5 - 6 m) and therefore to work normally even when connected to the power supply.
Page 33 DO NOT use power supplies other than the one supplied with the product. OptoJump Next contains rechargeable Li-Ion batteries (1800 mAh). Battery substitution must exclusively be carried out by authorized personnel. Do not directly connect the cable to the 3-pole socket on the drum.

Page 36 To search for a particular athlete or to filter data (e.g. search for all athletes beginning with “Ros”), insert the text in the box at the top left and press <Search>. To remove the filter, press <Delete filter>. Pressing the button <New Athlete> opens a new panel in which the new athlete’s data must be inserted.
Page 37: Athlete Data Input Mask
After a few seconds the measurement is displayed and can be confirmed or repeated. The measurement (essential for the treadmill tests) is useful only with the 1 cm OptoJump Next version, as the resolution of the 3 cm version is too low to give a reliable value (e.g. depending on how the foot is placed, the measurement can vary from 15 to 18 cm).

Page 53: Video Feedback
4.2.1.2 V IDEO EEDBACK The main idea of this new feature is to show the patient directly some main parameters of the test he/she is carrying out. This allows to request real-time 'corrections' of some trial anomalies, making the test become an exercise, not only a diagnosis. Particular attention is paid to the concept of asymmetry, i.e.
Page 54 The new feature (presently available only for Sprint and Gait Tests; Treadmill Gait, Treadmill Run, and Tapping) is found in Test Module > Execute > Configure, with the two parameters 'Output second monitor' and 'Save Test Data.' When the 'Output Second Monitor' option is selected, a window is created on the second monitor (or on the same monitor, when the second one is not physically present), where the displaying of one test parameter asymmetry can be configured (e.g.
Page 55  Reference Value: only appears when Mode = Absolute Value and is the value taken as a reference when calculating the thresholds. Obviously it should be set in line with the type of measurement selected (e.g. 30 cm for height, 0.5 s for flight time, 70 cm for step length, etc.).
Page 56: Metronome
While performing certain exercises (gait, walking on the spot, jumps), some patients find it easier to maintain a cadence if they are able to follow a constant rhythmic sound. OptoJump Next has a virtual 'metronome' function, which can be used to set the cadence in bpm (beats per minute), and the tone (single or double).
Page 57: Define / Edit Tests
Click on one of the three categories to view the list of tests pre-defined by Microgate or those you have added yourself in the grid (in the example below ‘Three Jumps’ is a test added by the user).
Page 58: Main And Secondary Parameters
 Name: name identifying the test type (e.g. ‘left foot monopodalic’ or ‘continuous jumps 30 seconds’, etc.)  Test Type: this type indication is very important and conditions the fields below, which appear dynamically only after the type has been chosen from this drop-down menu: o Jump Test: type of test that measures flight time (and consequently height), as well as contact time during a series of jumps (in the former version this was called Contact/Flight time)
Page 59 Basic Configuration Parameter ↓ Test Definition Parameter ↓ Single Test Parameter For example: Under Utility/Basic Configuration set the ‘Minimum contact time’ to 60 ms. From this moment every time new types of ‘Jump Test’ are created, they will have a default value of 60 ms (if this value is acceptable, no further changes have to be performed in ‘Secondary Parameters’.).
Page 60 Figure 40 – Single Test Definition Settings However it might be necessary to change the parameter ONLY for this single test. Insert for example 75 ms and press <OK> or <Apply>. After all values have been recalculated, the data in the table with the numeric results and charts will change.
Page 61 4.2.2.1.1 Parameter Template The 'Template' field allows setting of secondary test parameters (in the definition but also at test level) following common usage cases. Let's suppose, for example, that a gait test is carried out on a modular system, with the athlete performing very short strides (typical of people who have had an injury), or shuffling the tip of the advancing foot.
Page 62: Jump Test
The available fields for the different test types are the following: 4.2.2.2 J 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 button, signal light, etc.) ...
Page 63: Reaction Times
4.2.2.3 R EACTION TIMES Main Parameters  Start type: Indicates what type of reaction the test must assess, that is:  “Visual stimulus”: on the PC screen a red circle becomes green after a random period of time; the athlete must ‘react’ to this stimulus (for example, by jumping) ...
Page 64: Sprint And Gait Test
 Entry point: allows to indicate if the entry point of the Sprint/Gait test is entering from the ‘interface side’ (drum) or from the ‘opposite side’. If ‘automatic’ is chosen, OptoJump Next automatically calculates the direction, considering the LED nearest the center of the foot as the beginning of the LEDs.
Page 65  Test timeout [ms]: this is the end of test timeout in milliseconds; if during a Sprint/Gait test with ‘Timeout’ stop type no input or output signal is received from the measurement area by the OptoJump device for a period longer than or equal to the time set here, the test is considered completed.

Page 90 Should you realize that the assigned starting foot is wrong, just follow the above-stated procedure and switch the selection. Treadmill Running Test and Treadmill Gait Test. In this case the foot touching the ground after the START command is assigned as starting foot. If the START is assigned during a double support, as occurs quite often in Gait Tests, the starting foot is the one in front on the Treadmill.
Page 91 Of course it is possible to do this afterwards using the same method described above for the Sprint and Gait Tests on modular systems (even as regards possible foot assigning errors).

IMER AND HOTOCELLS OptoJump Next may be used in combination with the wireless timer and photocell kit called Witty. The photocells have the purpose of giving the external start impulse and to stop the test, as well as recording intermediate times during the sprint/run test with modular systems, if needed.
Page 119 START LAP1 LAP2 STOP Wireless Radio Transmission Max 150 mt. The test has to be set up as start and stop test = "External impulse" (which is given by the Witty timer when the athlete passes the photocells), with a number of intermediate times equal to the number of intermediate photocells of the system.

The following are some useful definitions to explain the values displayed on the table with numerical data: Figure 115 - Gait analysis terminology...
Page 173 Figure 116 - Gait Cycle: Stance & Swing Each gait cycle consists of two phases, where both feet are in contact with the ground, called Double Support. The first Double Support (DS1 in Figure 115 - Gait analysis terminology referred to the right foot) is also called ‘Load Response’, whereas the second (DS2) is called ‘Pre Swing’).

Page 181: Default Tests And Protocols
EFAULT ESTS AND ROTOCOLS Most tests are well-known standard tests (such as Squat Jump, Stiffness, Counter movement Jump) for which it is enough to follow the instructions on the screen (enter/exit test area, carry out a given number of jumps, wait for sound signal at the end of the test etc.). In this section you will find default tests and protocols which might raise some doubts as regards their initial setup and execution.
Page 182: Drift Protocol
6.1 D RIFT ROTOCOL The Drift Protocol is a test developed for verifying an athlete's or a patient's 'dynamic stability' by having him/her carry out 4 tests one after another on one leg measuring his/her displacement (drift) on the vertical and horizontal axis. Go to Test >...

Page 184 Each jump is displayed as a yellow dot (if you can not see 10 dots per leg some might be superposed); the two large red and green dots (left and right) represent the athlete's tendency to move into a certain direction (e.g. upwards to the right), whereas the dotted triangle indicates the 'stability area'.
Page 185: Drift Protocol
6.1.1 2D D RIFT ROTOCOL With its two-dimensional system (even the minimum 1 x 1 meter will suffice), the protocol can be significantly simplified by making the patient perform just 10 jumps (5 with the right and 5 with the left).
Page 186: Five Dot Drill Protocol
BFS Bigger Fast Stronger, developed especially for this test and contributing to its standardization. Place the two OptoJump Next bars outside the longer side of the rectangle with the drum at the test entrance. Figure 124 - 5 Dot Drill circuit and positioning of bars The protocol is made of 5 different exercises to be carried out 6 times WITHOUT PAUSES.
Page 187 The 5 tests are carried out as follows (a video explaining the exercise is available on our website): Up & Back 1. Start with feet on A and B 2. Jump rapidly with both feet on C 3. Jump putting one foot on D and one on E 4.
Page 188 Even though this is a single test, it must be carried out as PROTOCOL, because this allows to have a particular print report showing the 'level' based on the following table: DOT DRILL STANDARDS Less than 50 seconds Super Quick 50-60 seconds Great 60-70 seconds...
Page 189 Figure 127 - 5 Dot Drill report output The parameter '% Compared average' is calculated as difference between the average of all 5 tests and the average value of each single test. E.g. for Up & Back: (8.328 – 8.565) / 8.328 The fatigability index is calculated using the average of the first 6 contact time values and compared to the average value of the last 6 contact times.
Page 190: Gg' Protocol
6.3 'GG' P ROTOCOL This protocol (whose name is based on the initials of its inventors) is made of the following test series with the object of an initial athlete evaluation to be used during scouting phase. 1. Treadmill Gait Test at 5 kmh (usually for 30 seconds) 2.
Page 191 The 'Knee angle' parameter is an index which can be derived 'manually' from a video still image. Once the parameter with had been defined using the dedicated graphic tools, the value can be entered to the 'Indexes' section and will be showing in your print.

Page 193: Single Leg 3 Hops Protocol
6.4 S INGLE ROTOCOL This protocol allows evaluation of the functionality of the anterior cruciate ligament with two one- leg jumps consisting of 3 forward jumps each (possibly after post-injury rehabilitation) as regards power, as well as stabilization. Have the athlete carry out 3 forward hops (starting slightly out of the test area on the interface drum side) first with the left leg and then with the right leg.
Page 194 At the end of the test, a report can be viewed under 'Results', showing the main values divided by leg and differences in %. Figure 130 - Report Of course it is possible to see the details of a test by expanding the protocol and selecting 'View' in a test or 'Compare' to compare two tests.
Page 195: Mip (March In Place) Protocol
