38 YOM ambulates into your office with a chief complaint of neck pain following a motor vehicle accident in which he rear ended another car at 10mph. What is the next step with this patient?
No high risk factors. Patient may be full evaluated with a physical exam including active ROM
58
67 YOM ambulates into your office with a chief complaint of neck pain following a motor vehicle accident in which he rear ended another car at 10mph. What is the next step with this patient?
Because of age, is at high risk. Patient should be evaluated with a 3 view cervical radiographic study before any active range of motion is performed
59
20 YOM ambulates into your office with a chief complaint of neck pain following an injury in which a box of books fell on the top of his head. What is the next step with this patient?
Because of axial load to spine, is at high risk. Patient should be evaluated with a 3 view cervical radiographic study before any active range of motion is performed.
60
20 YOF ambulates into your office with a chief complaint of neck pain for past 2 years. 2 years ago she recalls straining her neck while swimming (not related to a diving injury). Remaining history including review of systems is unremarkable. What is the next step with this patient?
