In the subjective, you have learned that Paul has had back pain on and off for years. While asking him how long this bout of back pain has lasted, he states that he had been lifting boxes 2 months ago and since then has been getting progressively worse.  He cannot remember if there was a “pop” in his back when it occurred. He has only recently started noticing tripping over his right foot at times going up and down the stairs. He is a 20-year smoker and does not plan on quitting. He goes for walks 3 times a week with his wife who is in good health and can drive him to appointments. He only recently has stopped walking because of his fear of tripping over his foot. He explains that his walk is typically in a backyard trail as he lives near a busy road.
