Background and objectives: Low back pain is a health
problem affecting daily living in terms of pain,
movement and functional limitations. Lumbar
dysfunction is commonly found and diagnosed by
physical therapists. However, the relationships of
lumbar dysfunction and related factors are not yet
established. This study therefore aimed to investigate
the relationships between the diagnosis of lumbar
dysfunction range of motion limitation, and posture.
Methods: Study design and setting: The data of low
back pain patients were obtained from medical
records of Physical Therapy Center, Mahidol
University, 252 cases totally, by which 131 cases were
diagnosed as lumbar dysfunction and 121 cases
diagnosed as other pathologies. The relationships
between lumbar dysfunction, range of motion and
posture were investigated by chi-square test and the
characteristics of subjects were investigated by
independent t-test.
Results: Age, weight, and body mass index (BMI) were
not significantly different between the two groups.
Lumbar dysfunction group was correlated with range
of motion limitation in all directions especially lumbar
flexion and lumbar extension (p = 0.002, 0.006), but
lumbar dysfunction group was not correlated with
flat back posture.Conclusions: Lumbar dysfunction had a relationship
with range of motion limitation in all directions. Therefore,
physical therapists should emphasize on physical
examination and interventions regarding to range
of motion for holistic approach.
