Final answer:
The statement is false; physical therapists can and often do work with patients after hospital discharge through outpatient or in-home care. A strong understanding of physics, specifically biomechanics, is crucial to their role.
Step-by-step explanation:
The statement 'Once a patient leaves the hospital, the physical therapist will no longer work with him' is false. Physical therapists often continue to work with patients after they are discharged from the hospital. This is commonly done through outpatient therapy services or in-home health care settings, where physical therapists help patients continue their recovery and regain maximum mobility and independence.
Additionally, the notion that physical therapists do not require knowledge of physics is incorrect. Physical therapists must have a strong understanding of biomechanics, which is a branch of physics, to effectively analyze human movement and devise appropriate treatment plans. They use principles of mechanics and kinematics to understand and treat various physical conditions.
