For children with flexed-knee (crouch) gait due to neuromuscular or orthopedic conditions, externally powered microprocessor-controlled knee–ankle–foot orthoses (MPKAFOs) have demonstrated biomechanical and kinematic improvements in controlled settings. However, limited evidence has been available regarding their use in real-world home and community environments, particularly with respect to gait quality and quality of life.
The Hanger Institute for Clinical Research & Education recently conducted a prospective clinical study examining the use of an externally powered pediatric MPKAFO—the Agilik™ Smart Orthosis—over a three-month period following structured in-clinic training.
Sixteen children aged 6–16 years with flexed-knee gait due to neuromuscular or orthopedic conditions were enrolled, of whom 13 completed the full study.
Observed outcomes included:
- Significant improvements in gait quality, reflected by higher Observational Gait Scale scores
- Improved health-related quality of life, with statistically significant gains in EQ-5D-Y-3L scores
- Positive changes in parent-reported gait characteristics, including fewer reports of trips or falls and reduced foot drag
- No significant improvements in performance-based walking measures, suggesting a period of gait adaptation during early real-world use
These findings contribute to the growing body of clinical evidence describing how powered MPKAFO technology, such as the Agilik, has the potential to benefit pediatric individuals with flexed-knee gait outside gait laboratory settings.
