Ex Input:
Question: Does high levels of coach intent to integrate a ACL injury prevention program into training translate to effective implementation?
Answer: Coaching workshops can effectively increase coach attitudes, perceived behavioral control, and intent to implement a injury prevention program. However, high levels of behavioral determinants do not appear to translate to high levels of implementation compliance.

Ex Output:
no


Ex Input:
Question: Does degenerative spondylolisthesis affect the outcome of unilateral laminotomy with bilateral decompression in patients with lumbar stenosis?
Answer: Our study thus indicates that preoperative degenerative spondylolisthesis does not worsen the outcome of patients with lumbar stenosis undergoing unilateral laminotomy with bilateral decompression. These results suggest that lumbar fusion is often unnecessary in patients with degenerative spondylolisthesis and lumbar stenosis if the posterior decompression technique is unilateral laminotomy with bilateral decompression.

Ex Output:
no


Ex Input:
