Does quadriceps Muscle Strength correlate With Serum Vitamin D and Knee Pain in Knee Osteoarthritis?
These findings demonstrated a significant correlation between QMS with both serum vitamin D and knee pain, indicating a confounding role for quadriceps muscle in the association between serum vitamin D and osteoarthritis knee pain. On the basis of the findings of this study, vitamin D supplementation may affect pain by strengthening quadriceps muscle in KOA.
These results indicate that Cdc42/PAK/LIMK1 and p38/MK2/Hsp25 pathways, acting in parallel and modulating specific actin regulatory proteins, play a critical role in integrating responses during BMP-induced actin reorganization and cell migration.
