Insights
Exoskeleton-assisted rehabilitation improved gross motor function and balance in children with spastic cerebral palsy (CP). Outcomes varied based on ambulatory status, with non-independent walkers showing greater balance gains.
Area of Science:
- Pediatric rehabilitation
- Neurology
- Assistive technology
Background:
- Spastic cerebral palsy (CP) affects motor function in children.
- Exoskeleton technology offers potential for enhanced rehabilitation.
- Understanding ambulatory status impact is crucial for tailored interventions.
Purpose of the Study:
- To assess exoskeleton-assisted rehabilitation effects in children with spastic CP.
- To investigate if outcomes differ between independent and non-independent ambulators.
Main Methods:
- Exploratory longitudinal study of 20 children (10-13 years, GMFCS I-IV) with spastic CP.
- 10-week program: 20 sessions of 30-minute exoskeleton-assisted therapy.
- Assessed Gross Motor Function Measure-88 (GMFM-88), Pediatric Balance Scale (PBS), 10-Meter Walk Test, 1-Minute Walk Test (1MWT).
Main Results:
- Significant time effects observed for GMFM-88, PBS, and 1MWT.
- A significant time × group interaction was found for PBS (p=0.034).
- Non-independent ambulators improved in GMFM-88 and PBS; independent ambulators improved in 10MWT.
Conclusions:
- Exoskeleton-assisted rehabilitation shows promise for children with spastic CP.
- Outcomes may differ based on ambulatory status, particularly for balance.
- Further research is needed to confirm subgroup and long-term effects.
Aims:
To examine the effects of exoskeleton-assisted rehabilitation in children with spastic cerebral palsy (CP) and explore whether outcomes differ by ambulatory status.
Methods:
This exploratory longitudinal study included 20 children with spastic CP (aged 10-13 years; GMFCS I-IV) who completed a 10-week exoskeleton-assisted program (20 sessions, 30 min/session). Participants were classified as independent ambulators (GMFCS I-II, n = 11) or non-independent ambulators (GMFCS III-IV, n = 9). Outcomes were assessed at baseline and post-intervention, with 4-week follow-up in a subset. Measures included the Gross Motor Function Measure-88 (GMFM-88), Pediatric Balance Scale (PBS), 10-Meter Walk Test, and 1-Minute Walk Test (1MWT). Longitudinal changes were analyzed using mixed-effects models.
Results:
Main effects of time were observed for GMFM-88 (p = 0.001), PBS (p < 0.001), and 1MWT (p < 0.001). A time × group interaction was identified only for PBS (p = 0.034). The non-independent group showed baseline-to-post improvements in GMFM-88 and PBS, whereas the independent group showed an improvement in 10MWT.
Conclusions:
Exoskeleton-assisted rehabilitation may be associated with differential changes by ambulatory status in children with CP, particularly in balance outcomes, but subgroup and longer-term findings should be interpreted cautiously.
