7 Operation in general

This chapter describes how the Crosswalker is used without the chipcard function. All the machines in
the EN-Cardio group have a uniform operation. For a description of how EN-Track is used with the
chipcard function, please consult chapter 11.
The Crosswalker must be operated under the supervision of the physiotherapist or other suitably qualified
person. Only the therapist should attempt to interpret the results of the training session.
7.1

Manual operation

The Crosswalker can be operated manually. All you need to do is decide which form of exercise you want
to execute.
The options are:
• Constant power
• Constant torque
• Constant heart rate (pulse)
7.1.1

Constant power (W)

This position ensures that the power remains constant irrespective of the Crosswalker speed and heart
rate: the power (20-400W) can be increased or reduced using the rotary button (even during the training)
in 5W increments.
7.1.2

Constant torque (Nm)

The resistance will be maintained at a constant level so that a constant torque (constant resistance) is
created. The value of a constant torque (5-60 Nm) can be increased or reduced using the rotary button
(even during the training) in 0.5 Nm increments.
7.1.3

Constant heart rate (bpm)

The ergometer will bring the patient's heart rate to the pre-set value and then keep it there. This is done
by adjusting the power so that the pre-set heart rate (according to the signal from the Polar® chest strap,
ear clip or the hand/pulse measurement) is achieved and maintained. The measured value is shown at
the extreme right of the first line of the exercise screen, under the heart indicator. The desired value can
be increased or reduced in 1 bpm increments (between 40 - 210 bpm).
During the training (in which a warm-up is recommended so that the heart rate does not rise too quickly)
the pre-set desired heart rate can be changed by using the rotary button to set the new value. After the
rotary button has been operated the desired value will also appear at the bottom-centre of the LCD
screen.
