1.2. Intended Use

The FROG gait trainer provides gait and balance support in patients with walking

difficulties and can be used in the rehabilitation of gait. It has weight bearing handles and

arm rests and a foldable seat as resting position. It can be used indoors in hospitals,

therapy centers and ambulatory activities at home.

6

1.3. Safety Information

• The walker should be used indoors and on fairly firm and level ground

• Maximum weight of the user needs to be observed

• Instructions for use should be read carefully before first use. Instructions for use should be kept and

remain with the product for future reference.

• All locks and adjustment knobs on the frame, armrests, seat and wheels need to be checked before
first use and at regular intervals.

• The walking aid should not be used without an accompanying person. Accompanying persons must
be adequately instructed.

• The users should remain within the frame during use.

• Adjustments for handle and the frame width need to remain within the marked maximum limits.

Contraindications :

Users not being able to tolerate an upright position (circulatory issues) or tolerate weight-bearing
(osteogenesis imperfecta, severe osteoporosis, joint instability, severe contractures), as well as
significant lack of head control.

Please report any serious incident that occurred in relation to the device to the manufacturer, XentiQ
Partners Pte Ltd, and to the competent authority of the Member State where the user is established.

2. Operation

2.1. Therapy Application

FROG is used to teach children and adolescents who need additional support and stabilization of the upper
body due to disorders of the nervous and muscular system to walk and move independently.

The use of this walking aid during therapy should be supervised by a clinician. The suitability of the device
depending on the degree of the condition should be assessed by a doctor or therapist and settings or
adjustments made in an appropriate manner.

Particular attention should be paid to the position of the user’s feet and, if necessary, the tendancy to cross the
feet. The use of lower leg orthoses is necessary in many cases. Getting in and out of the walker must be done
with the support of the supervisor. The child should grip the handles tightly and place their forearms in the
armrests. If there is insufficient control of the arms they can be stabilized with straps in the armrests.

The supervisor should accompany the user either in front of or behind the walker, paying particular attention
to lateral stability (support with hands if necessary), as well as the position of the feet (avoid crossing).

The initial training takes place step by step, which can be promoted in a playful way (e.g. with a ball). Attention
must be paid to fatigue, whereby regular breaks can be taken using the seat. Folding down and taking the seat
as well as transferring back to standing must be practiced progressively under guidance and can then be done
autonomously in most cases.

2.2. Unfolding the Walker

The rear wheel of the walker should be
supported on the ground to release the
plunger lock.

1. Push the folding lock lever inwards to

disengage right lock on frame.

Note: There is no need to unlock the left lock for

unfolding.

Unlock

11

1. Pull back the rear frame against front

wheels on the ground.

2. Once walker is upright, ensure locks on

both sides are ‘engaged’ and in locked
positions.

Caution: Please ensure locks are fully

engaged before use.

12

2.3. Folding the Walker

1. Push folding lock levers on both sides of the

links.

2. Holding on to rear frame pull backwards

3. Fold walker until right lock engages to lock

(for models M1-X, M3-X, L1-X and L-3X
with armrests; other models do not have
armrest).

5. The walker is now secured and folded.

14

2.4.Attaching Arm Supports

(for models M1-X, M3-X, L1-X and L-3X with armrests; other models do not have armrest).

Each armrest needs to be on the correct side of the walker:

• Take note of section of arm rest that should face outwards (see below circled in red)

• Handle and knob should face forward

• Armrests can only be engaged in holder on correct side

15

1. Locate the armrest shaft socket.

2. Pull lock out and hold it in position.

3. Holding the aluminium shaft, engage the

arm support into the socket.

4. At desired position, release lock ensuring

pin has engaged with the hole in the shaft. If

not engaged, gently slide the shaft up or

down until lock snaps in.

Refer to page 26 on how to re-adjust

armrest height.

3. Lift seat

(for models M1-X, M2-X, L1-X and L-2X with seat; other models do not have seats).

3.1. Seat Lifting Force Adjustment

Lift force of the seat is controlled by mechanisms located on both the left and right below
the seat. There are two adjustable components for each side - [A] and [B].

[A] [B] [B] [A]

Important: Scales [A] and [B] should be adjusted equally on BOTH sides.

Adjustments should also only be done with seat in flipped up position.

18

High lifting force

Line marks
on ring

Medium lifting force

Low lifting force

[A] controls the lifting force acting on the user
when in sitting position. The higher the lifting
force, the easier it is to get up.

[B] controls the transition force when the seat is
in half elevated position. Decreasing [B] means it
will be easier to push the seat down in transition.

[A]

[B]

Starting on one side, turn Knob [A] to adjust
desired lift force which acts when the seat is
mostly lowered down; either to low (1),

medium (2) or high (3). Adjust Knob [B] to
the same level.

Repeat the same adjustments on the other
side.

Adjustments should be done with seat in

5. Maintenance and Cleaning

5.1. Maintenance

After sufficient cleaning, checking for function and defects at regular intervals (approx. 1 month).
If damaged, the relevant parts must be replaced

1. Check the correct function and locking of the spring plungers on the seat adjustment (2), armrests
(2), folding links (2), parking brakes on the rear wheels (2) and steering wheels (4), as well as the
clamping screws for the handles on the armrests ( 2).

2. Check that all screws and nuts are properly tightened.

3. Check for dirt on the wheel hubs, steering bearings of the front wheels and the telescopic lock of
the folding lock; clean if necessary.

4. Check the correct function of the seat kinematics with special attention to the condition of the
suspension points of the seat.

5. Check the firm and torsion-free condition of the frame width adjustment behind the backrest
(screws firmly tightened).

6. Check the condition of the soft moldings (seat, back, armrests, handles) for cracks and breaks.

7. Check the condition of the wheels and tires for wear and damage; check the condition of the wheel
bearings (excessive play).

8. Check the plastic fastening parts (black) of the seat module and armrests for cracks, breaks and
discoloration.

9. Check the condition of the tubular frame parts for any cracks or bends.

10. Check that the anti-reverse is working properly on both rear wheels when engaged.

35

Clean all surfaces and
frames with a damp sponge
or cloth using soapy water.
