Final answer:
Patients with peripheral vascular disease or musculoskeletal disorders can be evaluated using thallium-201 stress testing or may receive assistance from physical therapists for their condition instead of traditional stress testing methods.
Step-by-step explanation:
Patients with peripheral vascular disease or musculoskeletal disorders who are unable to perform traditional forms of stress testing, such as treadmill or bicycle ergometer exercise tests, may be evaluated using alternative methods. One such method is the administration of thallium-201 followed by a specialized imaging stress test that allows medical professionals to analyze heart function and blood flow without the need for physical exercise. In some cases, Physical Therapists (PTs) may also be involved in the evaluation and treatment process as they are experts in body mechanics and can help patients with muscle or joint injuries through therapeutic exercises and other treatment modalities.
