Trial Summary

Will I have to stop taking my current medications?

The trial information does not specify whether you need to stop taking your current medications.

What data supports the effectiveness of the treatment Load Modulation for cerebral palsy?

The study on the Anti-Gravity Treadmill (AlterG) training, which is a form of load modulation, showed that it can reduce neuromuscular abnormalities and manage spasticity in children with cerebral palsy. This suggests that similar load modulation treatments might be effective for cerebral palsy.12345

Is Load Modulation safe for humans?

The research on large amplitude movement therapy, which may be similar to Load Modulation, shows that children with cerebral palsy tolerated the therapy well with no adverse effects reported.16789

How does the Load Modulation treatment for cerebral palsy differ from other treatments?

Load Modulation for cerebral palsy is unique because it involves using body-weight support and exoskeleton assistance to improve walking patterns. This approach focuses on reducing the load on the body and providing mechanical assistance to help patients achieve better gait and knee extension, which is different from traditional therapies that may not use such advanced technology.1011121314

What is the purpose of this trial?

The purpose of this study is to investigate lower limb impairments in children with bilateral cerebral palsy during stepping tasks.

Eligibility Criteria

This trial is for children and teenagers aged 5 to 19 who can step up independently, with or without help from devices. It's specifically for those with bilateral cerebral palsy where legs are more affected than arms, but also includes typically developing individuals without movement-affecting conditions.

Inclusion Criteria

I either have no medical conditions affecting movement or have cerebral palsy with my legs more affected than my arms.
I am between 5 and 19 years old.
I can step up on my own, with or without help from devices.

Exclusion Criteria

I have trouble understanding or following instructions.
Comorbidities that would make participation unsafe.
I had surgery on my leg or foot in the last year.

Findings from Research

In a study of 76 children with cerebral palsy, those using seating systems with medial knee support (MKS) experienced a significant increase in hip displacement, as measured by the Reimer's migration index, from 26.89% to 44.18%.
The rate of hip displacement progression was notably higher in the MKS group at 14.72% per year compared to 7.82% per year in the control group, suggesting that MKS may worsen hip displacement in these children.
