Final answer:
The claim that ROM exercises should occur every 2 hours in CVA patients is false; exercise regimens are tailored to the individual patient and studies mentioned do not address physical exercise frequency.
Step-by-step explanation:
The statement ROM exercises should occur every 2 hours in CVA patients is false. Range of motion (ROM) exercises frequency for CVA (cerebrovascular accident) or stroke patients is typically individualized based on the patient's specific needs, condition severity, and the rehabilitation plan devised by healthcare professionals. It is not universally recommended to perform these exercises every two hours. Stroke rehabilitation protocols may employ ROM exercises less frequently, and the paired studies mentioned focus on the use of a software program for regaining problem-solving skills rather than physical rehabilitation frequency.
