Episode notes
Bernstein's Central Problem And Sparse Study
- Bernstein framed the degrees-of-freedom problem as central to motor control and proposed freezing as a solution.
- Despite its influence, the idea has seen little empirical follow-up or theoretical development.
Very Few Empirical Tests Exist
- Guillermas et al. found only 13 studies testing Bernstein's freezing/freeing hypothesis in 53 years.
- This tiny literature contrasts sharply with the concept's canonical status in the field.
Two Forms Of Freezing
- Bernstein described freezing as either immobilizing joints or coupling parts so they act together.
- Both strategies reduce independent elements the nervous system must coordinate early in learning.
