Recommended use
The Dynamic Pacer gait trainer is a Class 1 medical device. It is designed to help a client
learn to walk. For a client lacking active use of his or her trunk and leg muscles, the Pacer
provides the necessary support during gait training and requires little or no weight-bearing.
The large Pacer is recommended for clients with elbow height of 32"– 47" (81–119 cm).
The maximum working load for the large Pacer is 200 lbs (91 kgs).

Upper frames
Height Adjustment
To adjust the frame up or down, use use
trigger (A).
Standard upper
The standard upper frame adjusts in height
and provides support for various prompts
and accessories.
Dynamic upper
To prevent serious
injury:
• Keep hands clear of dynamic body
support mechanism while Pacer is in
use (see figure 8b).
• When dynamic weight bearing and/or
lateral weight shift mechanisms are
unlocked, position arm prompts so
that client’s hands are kept clear of
frame and column.
The dynamic upper provides dynamic body
support by allowing up/down and side-to-
side movement of the upper frame.
To lock or unlock vertical up/down
movement (dynamic weight bearing), lift
upper frame to unweight system, and use
trigger (B).
To lock or unlock side-to-side movement
(dynamic weight shift ): use trigger (C).
The default force range of the dynamic
weight bearing system will be fine for
most users. However, it can be adjusted
if needed, by turning screw (D) with the
hex wrench provided. Turning the screw
clockwise increases force.
To avoid damaging the
DWB system, stop turning
when the screw bottoms out (maximum
force) or when the screw becomes loose
(minimum force).

Placement of accessories on the frame
will vary according to the position and
abilities of the client and the number of
accessories used.
For slimmer clients, the clamps for any
accessory can be attached on the inside
of the top bar (see figure 11c). This
positions accessories closer to the client. To
reposition clamps and posts (see Page 16).

WARNING
Hand loops
To prevent tipping and
resulting injury, do not
position handloops, arm prompts or arm
platforms at the extreme ends of the top
bar (see figure 12a).
Attaching
When the Pacer is used in the anterior
position, it is recommended that hand
loops are attached forward of the frame
cross bar (see figures 12b and 12c). This
creates stable positioning and leaves plenty
of room for other accessories.
Hand loop clamps can be attached on the
outside of the top bar (see figure 12b).
For slimmer clients, the clamps for any
accessory can be installed on the inside
of the top bar (see figure 12c). This will
position the prompts closer to the client.
To reposition clamps and hand loop posts
(see Page 16).

bar (see figure 14b). This creates stable
positioning and leaves plenty of room for
other accessories.
The arm prompt clamps can be attached
on the outside of the top bar (see figure
14b). For slimmer clients, the clamps for
any accessory can be attached on the
inside of the top bar (see figure 14c). This
positions accessories closer to the client.
