Q: In this task, you are given a passage which has a question and the context. You have to generate an answer to the question based on the information present in the context.
Context: Prospective cohort.', 'Elbow stiffness is the most common adverse event after isolated radial head fractures.', 'To assess the effect of coaching on elbow motion during the same office visit in patients with such fractures.', 'We enrolled 49 adult patients with minimally displaced radial head fractures, within 14 days of injury. After diagnosis, we measured demographics, catastrophic thinking, health anxiety, symptoms of depression, upper extremity-specific symptoms and disability, pain, and elbow and wrist motion. The patient was taught to apply an effective stretch in spite of the pain to limit stiffness, and elbow motion was measured again.', 'With the exception of radial deviation and pronation, motion measures improved slightly but significantly on average immediately after coaching. Elbow flexion improved from 79% (110 22) of the uninjured side to 88% (122 18) after coaching (P<.001); elbow extension improved from 71% (29 14) to 78% (22 15) (P=.0012).\Question: Does coaching of patients with an isolated minimally displaced fracture of the radial head immediately increase range of motion?
A:
Instruction that stretching exercises are healthy even when painful resulted in immediate improvements in motion. Prospective studies comparing different strategies for coaching patients regarding painful stretches might help clarify the optimal approach.
