Muscle power and force may influence cortical bone strength via distinct mechanisms: findings from a cross sectional study of high bone mass cases and controls

Hardcastle Sarah A , Gregson Celia L , Rittweger Jorn , Ward Kate A , Tobias Jon H

Background: Relationships between muscle function and bone have been examined using a range of techniques, with conflicting results. We aimed to determine these associations within an adult population comprising individuals with high bone mass and family controls.Methods: Recruitment was from four UK sites within the high bone mass (HBM) study; cases and unaffected family controls were pooled. Peak ground reaction force and peak power, during a multiple ...

Extreme high bone mass (HBM) may be monogenic (e.g. due to mutations in SOST or LRP5) or polygenic, due to variants in the same genes determining bone mineral density (BMD) as found in the general population. We aimed to determine the genetic cause underlying HBM in an extreme HBM population.258 unexplained HBM cases (defined as L1 Z-score ≥+3.2 plus total hip Z-score ≥+1.2, or total hip Z-score ≥+3.2 and L1 <...
