The basic pattern of arm and leg movement during rhythmic locomotor
tasks is supported by common central neural control from spinal and
supraspinal centers in neurologically intact participants.
The purpose
of this study was to test the hypothesis that following a
cerebrovascular accident, shared systems from interlimb cutaneous
networks facilitating arm and leg coordination persist across locomotor
tasks. Twelve stroke participants (>6 months post CVA) performed arm
and leg (A&L) cycling using a stationary ergometer and walking on a
motorized treadmill. In both tasks cutaneous reflexes were evoked via
surface stimulation of the nerves innervating the dorsum of the hand
(superficial radial; SR) and foot (superficial peroneal; SP) of the less
affected limbs. Electromyographic (EMG) activity from the tibialis
anterior, soleus, flexor carpi radialis, and posterior deltoid were
recorded bilaterally with surface electrodes. Full-wave rectified and
filtered EMG data were separated into eight equal parts or phases and
aligned to begin with maximum knee extension for both walking and
A&L cycling. At each phase of movement, background EMG data were
quantified as the peak normalized response for each participant and
cutaneous reflexes were quantified as the average cumulative reflex over
150 ms following stimulation. In general, background EMG was similar
between walking and A&L cycling, seen especially in the distal leg
muscles. Cutaneous reflexes were evident and modified in the less and
more affected limbs during walking and A&L cycling and similar
modulation patterns were observed suggesting activity in related control
networks between tasks. After a stroke common neural patterning from
conserved subcortical regulation is seen supporting the notion of a
common core in locomotor tasks involving arm and leg movement. This has
translational implications for rehabilitation where A&L cycling
could be usefully applied to improve walking function.
