OBJECTIVE: To identify the effect of a novel augmented core stabilization
exercise technique on physical function, pain and core stability in patients with
chronic low back pain. DESIGN: A block randomized controlled trial with two
groups. SETTING: A sports rehabilitation clinic. Participants: Forty patients
with low back pain (20 experimental, mean (SD) age 50.35 (9.26) years and 20
control, 51.30 (7.01)), 19 men and 21 women. INTERVENTIONS: In the experimental
group ankle dorsiflexion was used in addition to drawing in the abdominal wall;
the control group involved drawing in the abdominal wall alone. Both groups
received the same conventional physical therapy training three days a week for
eight weeks. MAIN OUTCOME MEASURES: Physical disability instruments; Oswestry
Disability Index and Roland Morris Disability Questionnaire; pain intensity
assessments; visual analogue scale, Pain Disability Index, and a pain rating
scale; and core stability measures, such as the active straight leg raise, were
determined at pretest, posttest and two-month follow-up. RESULTS: After the
intervention, the experimental group showed significant greater improvement at
two months compared with the control group. Physical disability results included
Oswestry Disability Index (P = 0.001, from 24.25 (7.08) to 13.35 (4.17)) and
Roland Morris Disability Questionnaire (P = 0.001, from 15.55 (1.99) to 8.15
(1.69)), pain intensity including visual analogue scale (P = 0.001, from 6.30
(1.03) to 3.35 (0.59)), Pain Disability Index (P = 0.001, 31.25 (5.44) to 19.00
(3.58)) and pain rating scale (P = 0.001, from 72.25 (18.73) to 50.10 (15.47)),
and the core stability test such as active straight leg raise (P = 0.001, from
7.40 (0.75) to 2.15 (0.49)). CONCLUSIONS: This study provides the clinical
evidence that adding ankle dorsiflexion to drawing in the abdominal wall gave
increased benefit in terms of physical disability, pain and core stability in
patients with chronic low back pain.
