Eligibility
Key inclusion criteria
Male and female participants with chronic non-specific low back pain. This group excludes those with specific low back pathologies (as assessed from described history of
participants), which introduces confounding factors for interpretation of the results.
Participants will have had LBP for at least 12 weeks and have provided written informed consent confirming
their participation. Participants must have a minimum level of disability caused by their LBP that scores at
least 15% in the Oswestry Functional Disability Index (ODI) to be included in the study. This will discriminate
the level of disability from that experienced by the normal population.
Minimum age
18 Years
Maximum age
45 Years
Sex
Both males and females
Can healthy volunteers participate?
No
Key exclusion criteria
Participants will be excluded for the following reasons: presence of severe postural abnormality or
neuromuscular disorder, previous diagnosis of pathology (confirmed by previous magnetic resonance
imaging or radiograph), presence of pain radiating below the knee with a passive straight leg raise indicating
disc and nerve involvement.
Participants must not have engaged in any specific core stability training program in the last 3-months, and
must not be regularly seeing a physiotherapist or any spinal manipulation practitioner.

Summary
Brief summary
Of significant concern for healthcare treatment costs around the world are those individuals
with chronic low back pain (LBP). While exercise is a first-choice treatment for LBP there is no
consensus on the best type of exercise to use, with all modes of exercise equally effective.
Core stability exercises are movements for the trunk with bodyweight resistance. Core stability
training is thought to be the most effective exercise mode to improve neuromuscular control of
the trunk, however research evidence to support this is lacking. Improving neuromuscular
control of the trunk is one of the primary physiological mechanisms by which improvement in
low back pain patients is observed.
There is a lack of research comparing core stability training to other modes of exercise for low
back pain. If the literature reviews are indeed correct that no one mode of exercise is superior
to any other, it may be likely that an exclusively aerobic training modality may be just as
effective as a core stability program for improving pain, disabilty, fear avoidance, and
neuromuscular control of the trunk.
The aim of this study is to randomly assign participants with chronic low back pain to an 8
week exercise trial of either core stability or general aerobic exercise. Both groups will be
directly supervised, and measurements of pain, disability, fear avoidance beliefs, and trunk
neuromuscular control will be made before and after the 8 week program.
