The Claim

Adults with osteogenesis imperfecta type I exhibit significantly lower daily step counts and moderate-to-vigorous physical activity levels than healthy controls, resulting in reduced overall physical activity associated with lower bone and muscle mass.

In plain English

Adults with osteogenesis imperfecta type I take fewer steps and engage in less intense physical activity than healthy adults, and this is linked to lower bone and muscle mass.

See the scientific wording

Adults with osteogenesis imperfecta type I have significantly lower daily step counts and moderate-to-vigorous physical activity levels compared to healthy controls, indicating reduced overall physical activity that may contribute to lower bone and muscle mass.

Why this might work

People with this condition move less because their bones break more easily, so their muscles don't get enough exercise. This lack of movement means their bones don't get the signals they need to stay strong, and their muscles don't grow or stay as large. Over time, both bones and muscles become weaker because they aren't being used enough.

    Adults with this bone condition take about 30% fewer steps and move less intensely than healthy people, and they also have weaker bones and smaller muscles — suggesting that moving less might be one reason their bones and muscles don’t stay as strong.
