The Claim
Adults with osteogenesis imperfecta type I have significantly lower muscle cross-sectional area in the lower leg and forearm than healthy controls, after adjustment for height, weight, age, and sex.
What the research says
Supports is higher
Support is ahead, but a single strong opposing study can change this.
These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.
Adults with osteogenesis imperfecta type I have smaller leg and forearm muscles than healthy adults, even when accounting for differences in height, weight, age, and sex.
See the scientific wording
Adults with osteogenesis imperfecta type I exhibit significantly lower muscle cross-sectional area at the lower leg and forearm compared to healthy controls, even after adjusting for height, weight, age, and sex, suggesting a systemic reduction in muscle mass that may contribute to reduced mechanical loading on bone.
Abnormal collagen in bones makes them stiffer and less responsive to muscle forces, which reduces the signals that tell muscles to grow. Without these signals, muscles in the arms and legs stay smaller than normal.
What the research says
1 studyPeople with this bone condition have noticeably less muscle in their arms and legs than healthy people of the same age and size, and the study measured this directly using special scans.
