PMID: 40086127
Background: Toe walking in children with cerebral palsy is typically less stable and less energy-efficient than plantigrade walking in typically developing children. We hypothesized that children with cerebral palsy may,...

Front Rehabil Sci
. 2022 Oct;
2:789165.
PMID: 36188793
Effective science-based motor rehabilitation requires high volume of individualized, intense physical training, which can be difficult to achieve exclusively through physical 1-on-1 sessions with a therapist. Home-based training, enhanced by...

Eur J Appl Physiol
. 2022 Apr;
122(6):1459-1471.
PMID: 35366090
Purpose: Fatigue is frequent in adults with cerebral palsy (CP) and it is unclear whether this is due to altered corticospinal drive. We aimed to compare changes in corticospinal drive...

. 2022 Mar;
127(4):1147-1158.
PMID: 35320034
Sensory feedback through spinal interneurons contributes to plantar flexor muscle activity during walking, but it is unknown whether this is also the case during nonlocomotor movements. Here, we explored the...
