Becker GEOTM

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 riple Action AFOs.

Additionally, the GEO may be used as a therapeutic aid for

patient rehabilitation and mobilization.

The Becker GEO is designed to be used with Becker’s

evidence-based Systematic Tuning Procedure

for Triple Action Ankle Joints, which allows

clinicians to quickly and easily tune the

orthosis to determine the unique

supportive needs of the patient.

Ankle alignment, plantarflexion

/ dorsiflexion spring stiffnes

and range of motion are all

independently adjustable to help

simplify tuning.

The Becker GEO comes

fully assembled and includes

adjustment tool kit, heel lifts,

product manual, tuning procedure

and carrying case.

Adjustment

Triple Action ankle alignment, range of motion, and spring stiff ess 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. Dorsi exion and plantar exion range of motion settings change

the relative dorsi exion and plantar exion range of motion irrespective of the

ankle alignmentment setting. Spring stiff ess is adjusted by changing the

spring con guration.

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 man ement of mild

swing phase gait deficits. If higher stiffness is equired, the component’s resist can

be configu ed with four diffe ent stiffness options

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.

Becker GEOTM

The stiffness of spring configuration 1 is about 3 times higher tha a

conventional metal ankle joint.

With the Booster Spring installed, spring stiffness inc eases linearly with the

spring configuration numbe . Spring configuration 5 is about 18 times stiffe

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 configuratio

(Figure 6).

Figure 4. Adjust the booster to

15° ROM.

Cleaning Instructions

The 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:
