It might be that the participants in this study were
clinically too good for the Lokomat. However, we tried
to accommodate this flaw by applying different training
modes, and there were only 2 participants, who were able
to acceptably manage the most difficult training mode.
Nevertheless, strength training is customizable to a much
higher extent than RAGTand the therapist can specifically
address weaknesses that result in straight improvements
of function.
Participants did not perform other physical exercises
besides the interventions within this study. However, all
but one participant (P05) were community ambulators
(with assistive devices) and ambulatory activity besides
our trainings was not monitored.
The average intensity of pain in this sample varied much,
and it remains speculative whether RAGT could alleviate
pain more in participants who experience weaker or in
those with stronger pain. While one participant in our
study with strong pain profited from the training (P04),
the participant who reported the highest pain intensity
(P09) did not show any change in pain intensity due to
the training.
