Background and Objective: Lumbar Instability (LI)
could be classified into many subgroups which Clinical
Lumbar Instability (CLI) was considered as affected
on patients. CLI defined as the translation and
rotation values of each lumbar segment greater than
normal translation and rotation with clinical sign. CLI
could result in patients in many aspects which had
been reported. However, the evidence on reporting
of lumbar instability have different methodology. The
aimed of this study was to report CLI in patients with
chronic low back pain by radiography.
Methods: This was a cross-sectional descriptive study
in 50 chronic low back pain (CLBP) participants aged
33.7±13.3 years. Data were collected by interview for
demographic data and flexion-extension radiograph
for diagnosis instability. Descriptive statistics were used
for calculation.
Results: This study found that the amount of CLI was
92%. Age of participants with CLI range from 20-59,
which the participant aged 30 to 39 and 50 to 59 years
showed 100% of CLI, aged 20 to 29 and 40 to 49 years
showed 93.3% and 66.7%, respectively.
Conclusions: The finding of prevalence, age, and LBP
period in this study demonstrated that CLI could be
occurred in people who aged from 20 years onward There were young patients with CLBP, the practitioner
should aware of assessment about CLI in order to
providing suitable management
