Gary was injured in an automobile accident that severed the motor neurons innervating his quadriceps Even though he has had extensive physical therapy is still suffering muscle atrophy?

Gary is suffering from continuous muscle atrophy even after undergoing physical therapy because the severed motor neurons innervating his quadriceps can no longer transmit signals from the central nervous system to the muscles. Without these neural signals, the quadriceps muscles don't receive the necessary stimulus for growth and maintenance, leading to muscle atrophy. Physical therapy alone cannot regenerate damaged motor neurons or re-establish functional connections between the nerves and muscles. In such cases, alternative approaches like surgical nerve repair or assistive devices might be considered to address the underlying nerve damage and help mitigate further muscle atrophy.
