By slightly
moving their trunk forward (increase in speed) or backward
(decrease in speed), they could control treadmill
belt speed within a defined range. These modes enabled
us matching training intensity to the participants’ capabilities
and guaranteed active participation, whereas in
earlier clinical trials with the conventional system, theoretically,
participants could just be passive [21,29].
Speed was limited to 4.0 km/h (=1.11 m/s) in every
mode (average training speed in these patients usually is
around 1.5-2.0 km/h).
