Integration of the plantar grasp reflex as an indicator of ambulation potential in developmentally disabled infants
Insights
The plantar grasp reflex integration in infants predicts independent walking. Infants with reflex integration achieved ambulation, while most without it did not, showing its prognostic value.
Area of Science:
- Developmental Pediatrics
- Neuroscience
- Motor Development
Background:
- The plantar grasp reflex is a primitive reflex present in infants.
- Its persistence or integration is linked to neurological development.
- Assessing this reflex may offer insights into motor milestones like ambulation.
Purpose of the Study:
- To investigate the relationship between plantar grasp reflex integration and independent ambulation in developmentally disabled infants.
- To determine the prognostic value of the plantar grasp reflex for achieving unaided walking.
Main Methods:
- Studied 26 developmentally disabled infants.
- Assessed plantar grasp reflex integration in supported standing.
- Followed infants for 3-5 years to track ambulation status.
Main Results:
- All infants showing plantar grasp reflex integration achieved independent ambulation.
- Only 1 out of 13 infants who did not integrate the reflex achieved independent ambulation.
- A strong correlation was observed between reflex integration and walking ability.
Conclusions:
- The integration of the plantar grasp reflex is a significant predictor of independent ambulation in developmentally disabled infants.
- Absence of reflex integration suggests a lower likelihood of achieving unaided walking.
- This reflex serves as a valuable prognostic indicator in pediatric developmental assessments.
Abstract:
The integration or lack of integration of the plantar grasp reflex, as tested in supported standing, was investigated in 26 developmentally disabled infants and was related to the attainment of independent ambulation without assistive devices. All infants who displayed integration of the plantar grasp reflex later developed independent ambulation. Thirteen infants did not display integration of the reflex during three to five years of follow-up. Of those 13 infants, only 1 achieved independent ambulation. This preliminary clinical investigation provides evidence of the prognostic value of the presence or absence of the plantar grasp reflex as an indicator of ambulation potential in developmentally disabled infants.
