OBJECTIVES: To assess the bio-behavioral and physical performance characteristics
of individuals with chronic low back pain who demonstrated the pain
centralization phenomenon and received the McKenzie intervention using selected
bio-behavioral and physical performance measures at intake and at 5 weeks and 10
weeks after treatment. DESIGN: A prospective cohort study with assessment at
baseline and 2 follow-ups after completion of the McKenzie intervention. SETTING:
Outpatient orthopedic physical therapy clinics. PARTICIPANTS: Sixty-two
volunteers with chronic low back pain (28 men, 34 women; average ages 41.9 and
37.1 years, respectively). METHODS: The subjects completed pain and related fear
and disability questionnaires, underwent McKenzie mechanical assessment, and
executed selected physical performances. They then received the McKenzie
intervention. MAIN OUTCOME MEASUREMENTS: Outcomes measurements were repeated at
the end of the 5th and 10th weeks after treatment completion. Pain-related
disability and fear beliefs were assessed by using the Disability Belief
Questionnaire and Fear Avoidance Belief Questionnaires, respectively. The time
for repeated sit to stand, trunk forward bending, and customary and fast walking
were measured by stopwatch. Pain (anticipated versus actual reported) was
measured before and immediately after a given physical performance. Descriptive
statistics, paired t-tests, and repeated measures analysis of variance were used.
RESULTS: Significant improvements peaked at the end of the 5th week for all
outcome measures (P < .001), with slight increase in bio-behavioral variables at
the end of the 10th week. CONCLUSIONS: McKenzie intervention reduced pain and
related fear and disability beliefs and improved physical performances in
individuals with chronic low back pain. Improvements in physical performances
remained stable 10 weeks after treatment, regardless of the elevation in
bio-behavioral factors.
