Why do wheelchair bound people with paralyzed lower limbs develop thin weak leg and thigh bones?

Wheelchair-bound individuals with paralyzed lower limbs develop thin and weak leg and thigh bones due to lack of weight-bearing physical activity that is needed to stimulate bone growth and strength. Weight-bearing activities help bones absorb calcium and other minerals, leading to stronger bone density. Without this stimulation, bones can become thin and weak over time.
