Disuse atrophy is the wasting away of muscle tissue due to extended immobilization or decreased use. In this case, Joey's leg was in a non-weight-bearing cast, which means that he did not use his leg muscles for 8 weeks. As a result, the muscles in his leg became smaller due to the lack of stimulation, leading to disuse atrophy.
