Recurrent Low Back Pain:Linking Mechanisms to Outcomes
|ClinicalTrials.gov Identifier: NCT01085604|
Recruitment Status : Completed
First Posted : March 12, 2010
Last Update Posted : August 5, 2015
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.

Low back pain
Individuals with current low back pain attributed to poor trunk neuromuscular control (clinical instability).
Other: Core Stabilization
The 8-week core stabilization program emphasizes use of specific local stabilizing muscles (transverse abdominis[TrA], lumbar multifidus[LM]) to restore active control and stability to the trunk. This program emphasizes training using isometric co-contractions and a progression (3 stages) based upon a motor learning paradigm.
Stage 1: emphasizes neutral position of the spine and activation of the TrA and LM. Performance feedback is emphasized and monitored through observation and palpation.
Stage 2: promotes maintenance the co-contraction while performing movements of the trunk and superimposing movements of the upper and lower extremities. Trunk conditioning is also emphasized (i.e., curl ups, quadruped leg/arm lifts and side support). Feedback is gradually reduced.
Stage 3: emphasis on maintenance of the co-contraction while performing exercises on an unstable surface or during perturbation of the activity. Random practice patterns are used to enhance motor learning.
- Trunk Neuromuscular Control [ Time Frame: Baseline, 8 weeks ]Using surface EMG, trunk kinematics and force plate parameters. Trunk motor control is characterized and compared between groups and pre/post intervention in the low back pain group.
- Oswestry Disability Index [ Time Frame: Baseline, 8 weeks ]measure of functional limitations
