Recurrent Low Back Pain:Linking Mechanisms to Outcomes

Completed

• Conditions: Low Back Pain
• Interventions: Other: Core Stabilization

• Registration Number: NCT01085604
• Lead Sponsor: Drexel University

Brief Summary

The purpose of this study is to determine if trunk neuromuscular control strategies are changed by therapeutic exercises emphasizing core stabilization.

Hypothesis: subjects with low back pain who demonstrate clinically meaningful improvements in function and pain will have significantly improved trunk motor control strategies.

Hypothesis: measures of trunk control will demonstrate 'construct-validity'. This will be tested using a known group method demonstrating:

* no significant change in motor control measures within the untreated, healthy control group.

* significant changes within the low back subjects who demonstrate clinically meaningful improvements.

Detailed Description

A growing body of evidence suggests that poor neuromuscular control of the lumbopelvic region is an important finding in a large number of patients with recurrent and chronic low back pain and may play a role in recurrence of symptoms. Despite findings of altered trunk motor control in individuals with low back pain, the neuromuscular strategies underlying these alterations have not been satisfactorily characterized. The aims of this study are to(1) identify which neural control strategies are altered following a rehabilitation program that emphasizes trunk control and stability using a motor learning approach and (2) provide preliminary evidence of a link between hypothesized mechanism and effectiveness for programs designed to improve trunk control.
