Correct Body Mechanics
for Operating the Sit-To-Stand Trainer:
Figure 6
Selecting and Engaging the
Counterweight
Ask the user to sit back in their chair and begin by positioning
the Weight Selection pin at 40 lbs/18 kg, a good intermediate
counter-weight to start with. This counterweight may need to
be adjusted up or down depending upon the ease of standing
and the clinical goals. Increasing the counterweight will aid in
the standing motion and likewise decreasing the counterweight
will require more active standing effort from the client.
• Assistant can grasp the free end of rope and help raise the
counter-weight by leaning backwards, maintaining a straight
torso and using lower extremities and body weight to assist
with the pull.
• Pull in small increments rather than one long pull to raise
counterweight.
• Make sure the pulling motion is parallel to the rope that
connects the user. This is best accomplished by pulling from
behind either the left or right shoulder of the client.
• See Figure 6 for an illustration of the above instructions.
CORRECT BODY MECHANICS
The pulley system of the Sit-to-Stand is designed to ease
and assist the act of engaging the counterweight. The
technique shown in Figure 6 is the biomechanically correct
and easiest way for the trainer to pull the counterweight.
The counterweight should be raised by leaning backwards,
maintaining a straight torso, and using the lower extremities
to assist with the pull. When done this way, even relatively
light trainers can use their body weight to easily pull up the
counterweight. It is recommended that the counterweight be
pulled up in small increments rather than one long pull.
