Background and Objective: The assessment and
management in individuals with lumbar hyperlordosis
are important to prevent further musculoskeletal
disorders. The responsiveness is necessary to be
studied because it represents the ability of each
parameter to indicate the change overtime, which
awaits formal investigation. This study aimed to
investigate the responsiveness of biomechanical
parameters in individuals with lumbar hyperlordosis.
Methods: Fifteen individuals with lumbar
hyperlordosis, aged 20 to 30 years, were recruited.
The parameters measurement were angle of lumbar
lordosis (ALL), degree of hip flexion, degree of hip
abduction, degree of knee flexion, and percent
maximum voluntary isometric contraction (%MVIC) of
transversus abdominis/internal abdominal oblique
(TrA/IO), rectus abdominis (RA), external abdominal
oblique (EO), lumbar erector spine (LES), and
multifidus (MF). They were assessed 2 times: before
and after iliopsoas stretching.
Results: Change score, effect size, and standardized
response mean (SRM) were calculated to represent
the responsiveness of each parameter. The findings
showed that the most responsive parameter was ALL,
SRM of 1.61, while, the other parameters had lower responsiveness.
Conclusion: This study supported that ALL was the
most responsive parameter to detect the change in
individuals with lumbar hyperlordosis after the
intervention aiming for decreasing lumbar lordosis
