There was no difference between the interventions with
respect to PCI. Differences between resting and walking
heart rate were very small indicating that walking for
3 min at preferred speed was not a very energydemanding
load in the present sample. Additionally,
low walking speeds compared to those of the nondisabled
population led to a large statistical data spread.
Therefore, the PCI must be looked at critically after iSCI
which has been noted earlier [35].
Gait symmetry did not change, and this is in line with
results of another study [21]. It must be noted that all
but one (P05) subject had no relevant strength differences
between their right and left leg.
