72-year-old active healthy female currently under care for cervical, thoracic and lumbopelvic spine fixations and osteoarthritis presented with new symptoms of pain and tingling at the dorsum of her right foot, onset a week prior. She is not having difficulty walking.

The patient stated that 10 days ago, she had a fall at a local zoo and landed on her left hip, left knee and left elbow but was unaware of any injury to her right lower extremity. The fall did worsen her spinal complaints at her low back and left hip and caused right low back pain. This patient has had no history of right foot pain and is currently wearing orthotics for chronic pronation, prescribed at my clinic. She has no current diseases or illnesses except for the spinal concerns and mild osteoarthritis in her spine. She is not on any medications and is caretaking for her teenage grandson. She is retired but occasionally helps her grandson with volunteer work which requires light lifting.

Question: What examination procedures will you perform in your clinic to differentially diagnose this patient?
