2.

The Becker GEO is a prefabricated, carbon composite evaluation orthosis designed to manage moderate coronal plane postural abnormalities, while assessing the benefit of an AFO on ankle and knee stability. Based on the Triple Action ankle joint, the GEO can also help determine the appropriate booster spring configuration for definitive Triple Action AFOs. Additionally, the GEO may be used as a therapeutic aid for patient rehabilitation and mobilization.

AdjustmentTriple Action ankle alignment, range of motion, and spring stiffness independently adjustable. Ankle alignment rotates the component body about the pivot bearing to change the ankle angle without altering range of motion or resistance to ankle motion. Dorsiflexion and plantarflexion range of motion settings change the relative dorsiflexion and plantarflexion range of motion irrespective of the ankle alignmentment setting. Spring stiffness is adjusted by changing the spring configuration.

Loosen the alignment lock (inside the hex) ½ to ¾ turn to unlock the alignment adjustment.

The alignment adjustment range is ±10°

Adjusting Alignment

The recommended tightening torque for the alignment lock is: 10Nm (90 in-lb)

Figure 1. Unlock/ lock the PF ROM Adjustment using the 1.5mm hex wrench to loosen/ tighten the ROM Lock Set Screw.

Figure 2. Adjust the ROM setting to 0° by turning the Booster fully clockwise with the adjustment wrench.

Figure 3. Loosen the ROM Dial screw using the 2mm adjustment wrench and zero the ROM setting by turning the blue ROM dial. The ROM lock set scew serves as a reference for this adjustment.

Rotate the booster to adjust the ROM setting.

To zero ROM:

Adjusting Range of Motion

• Loosen the ROM lock set screw to unlock the adjustment (Figure 1).

• Turn the booster counter clockwise to increase ROM 5° per turn.

• Lock the booster by tightening the ROM lock set screw (Figure 1).

Notes:• The maximum ROM setting is 10° (2 turns of the Booster Spring).• The ROM is read directly from the blue ROM Dial.

To adjust ROM:

*The Booster Spring Unit cannot be removed from the Triple Action component housing. Doing so will destroy the Booster and void the product warranty.

Adjusting Spring Stiffness

The stiffness of spring configuration 1 is suitable for the management of mild swing phase gait deficits. If higher stiffness is required, the component’s resist can be configured with four different stiffness options.

Spring Configuration 1 2 3 4

Top Spring None Standard High High & Standard

Stiffness X1 (low)

X2 (moderate

X4 (high)

X5(very high)

Max. ROM 10˚ 10˚ 10˚ 10˚

*The Booster Spring Unit cannot be removed from the Triple Action component housing. Doing so will destroy the Booster and void the product warranty.

*Internal bottom spring under booster is covered with a lifetime warranty for defects in materials and workmanship.

6.

The stiffness of spring configuration 1 is about 3 times higher than a conventional metal ankle joint.

With the Booster Spring installed, spring stiffness increases linearly with the spring configuration number. Spring configuration 5 is about 18 times stiffer than a conventional metal ankle joint. The maximum active ROM for all spring options is 10 degrees.

1. Increase the ROM setting to 15˚ by turning the booster counter clockwise to decrease Booster Spring compression (Figure 4).

2. Remove the Booster Spring ROM dial screw and ROM Dial (Figure 5).3. Remove the Keeper Plate and install the desired spring configuration

(Figure 6).

Figure 4. Adjust the booster to 15° ROM.

Figure 5. Remove the ROM Dial Screw and ROM dial.

Figure 6. Remove the Keeper Plate and install the desired spring configuration.

Cleaning InstructionsThe GEO was designed as a multi-user device. Therefore, it is recommended that the GEO be cleaned after each use.

If no visible soiling is present:

1. Clean/Spray entire device with a hospital grade disinfectant and deodorizer, such as Impact.

2. Allow to dry completely prior to use.

1. Remove padding and straps and clean them with mild soap and water.

2. Allow straps to air dry.3. Wipe down the tibial section and

footplate.4. If necessary, disassemble and wipe

down the ankle joint.5. Reassemble the ankle joint and

lubricate as instructed in the Product Manual.

6. Clean/Spray entire device with a hospital grade disinfectant and deodorizer, such as Impact.

7. Allow to dry completely.8. Reattach straps and padding.

If visible soiling is present:
