How does pelvic spherical rotation contribute to the overall stability of the spine during movement? 


Best insight from top research papers

Pelvic spherical rotation plays a crucial role in enhancing the stability of the spine during movement. It is observed that pelvic motion acts as a hinge between the spine and hips, aiding in maintaining balance during bipedalism. The combination of pelvic rotation and moments, along with pelvic rotation and muscle forces, significantly increases the load-bearing capacity of the spine, stabilizing it against axial compression forces. Moreover, pelvic rotation is utilized to partially stabilize the passive spine in compression, relieving the musculature and enhancing overall stability. Therefore, pelvic spherical rotation is a key mechanism that contributes to spinal stability during movement, especially in scenarios involving spinal malalignment or degenerative changes.

Why does judgment tendency in affordances improve overnight?
5 answers
The improvement in judgment tendency in affordances overnight can be attributed to the adaptability and plasticity of the human brain, especially in response to altered body properties. Research suggests that individuals, particularly older adults, tend to judge more conservatively when their body properties are suddenly altered. However, after a period of habituation, older adults show adaptive behavior and tend to regain initial performance levels, indicating a reversal of the conservative judgment tendency. This adaptability is further supported by findings that training individuals through actual practice can lead to significant increases in judgment accuracy, with older adults adjusting their tendency towards less conservative judgments over time. Therefore, the overnight improvement in judgment tendency in affordances likely stems from the brain's ability to adapt and learn from new experiences and challenges.
