Summary
Pediatric lower extremity amputees demonstrate functional ambulation despite slower walking speeds and increased physiological demands. Their mobility is influenced by the extent of limb difference, yet they actively participate in daily life and sports.
Area of Science:
- Orthopedics
- Pediatric Rehabilitation
- Biomechanics
Background:
- Lower extremity amputations in children present unique challenges to mobility and participation.
- Prosthetic technology has advanced, enabling functional ambulation for pediatric amputees.
- Understanding the functional and physiological aspects of walking in this population is crucial for optimizing care.
Purpose of the Study:
- To assess the walking function in children with lower extremity amputations.
- To evaluate the relationship between the extent of limb difference and functional limitations.
- To compare the gait parameters and physiological responses of pediatric amputees to their non-amputee peers.
Main Methods:
- Utilized a combination of standardized questionnaires and objective gait analysis.
- Assessed 56 children with various types of lower extremity amputations.
- Collected data on gait parameters (e.g., speed, cadence, stride length) and physiological responses (e.g., heart rate).
Main Results:
- Pediatric amputees, as a group, exhibit slower walking speeds, reduced cadence, and longer stride lengths compared to typically developing children.
- Children with lower extremity prosthetics demonstrate significant functional capacity, including participation in sports.
- Increased heart rates were observed in pediatric amputees during ambulation, indicating higher physiological cost.
Conclusions:
- Pediatric amputees can achieve a high level of functional mobility and societal participation.
- The degree of functional limitation is directly related to the extent of the amputation.
- Pediatric amputees are willing to exert greater physiological effort to ambulate, highlighting their determination and adaptability.
