After the patient's pain resolves to a satisfactory level with the manipulation intervention, the results of the physical examination can be utilized to develop a series of stabilization exercises intended to improve trunk motor control and strength. The initial exercise prescription incorporates the results of the physical examination by determining pain-free positions and movements. Initial training should focus on strengthening the abdominal muscles and low back extensors. Such exercises have the ability to improve perceived disability in both the short- and long-term in patients with recurrent LBP.23 The patient should be instructed to report any peripheralization of pain during exercises or activities of daily living. The physical therapist must emphasize to the patient that the goal is centralization of pain (i.e., pain is felt in a more proximal location in response to repeated movements or sustained positions). The concept of centralizing pain should be utilized as a means to determine when to increase the frequency and intensity of his exercise program.24 Carefully administered exercises emphasizing motor control are effective for nonspecific, nonradicular LBP. Motor control exercises for the spine are more than teaching a patient the "neutral" position of the spine. Instead, the physical therapist must incorporate the results of the physical examination to determine the motions and positions of the lumbar spine that have the least potential to exacerbate the pain pattern. With some patients, that may mean more of a flexion bias, and in others an extension bias. The results ascertained in the physical examination dictate the control of the spine necessary for pain-free activity. A systematic review of 14 randomized controlled trials concluded that motor control when used in isolation or in conjunction with additional interventions decreased LBP and disability
