Clinical Integration of a Goal-Specific Virtual-Reality Biofeedback Treadmill Training Program for Children with...

Area of Science:

• Rehabilitation Medicine
• Biomedical Engineering
• Pediatric Neurology

Background:

• Cerebral palsy (CP) significantly impacts motor function, particularly gait.
• Virtual reality (VR) offers immersive environments for therapeutic interventions.
• Treadmill-based biofeedback can provide real-time gait analysis and training.

Purpose of the Study:

• To evaluate the effectiveness of a clinical VR treadmill-based biofeedback program.
• To assess changes in gait parameters in children and adolescents with CP.
• To determine the feasibility and adherence to VR biofeedback therapy.

Main Methods:

• Retrospective analysis of 17 children with CP (mean age 11.3 years, GMFCS level I/II).
• Participants underwent 7-12 VR treadmill biofeedback sessions over 3-6 weeks.
• Outcome measures included spatiotemporal parameters, dimensionless walking speed (DWS), Gait-Profile-Score (GPS), Gait-Variable-Score (GVS), and kinematics.

Main Results:

• Significant improvements in DWS (p=0.008) and step-length in the more-involved leg (p<0.001).
• Reduced variance in most spatiotemporal gait parameters (p<0.05).
• Small changes observed in kinematic waveforms of the less-involved leg (p<0.05).

Conclusions:

• VR treadmill biofeedback led to overall reductions in spatiotemporal gait deviations in children with CP.
• High participant adherence was noted, suggesting feasibility.
• VR biofeedback shows promise as a clinical intervention for CP gait rehabilitation, despite no consistent increase in knee extension angle.
