OBJECTIVE: To systematically review the evidence examining effects of walking
interventions on pain and self-reported function in individuals with chronic
musculoskeletal pain.
DATA SOURCES: Six electronic databases (MEDLINE, CINAHL,
PsychINFO, PEDro, Sport Discus, and the Cochrane Central Register of Controlled
Trials) were searched from January 1980 to March 2014.
STUDY SELECTION:
Randomized and quasi-randomized controlled trials in adults with chronic low back
pain, osteoarthritis, or fibromyalgia comparing walking interventions to a
nonexercise or nonwalking exercise control group. DATA EXTRACTION: Data were
independently extracted using a standardized form. Methodological quality was
assessed using the U.S. Preventive Services Task Force system. DATA SYNTHESIS:
Twenty-six studies (2384 participants) were included, and suitable data from 17
studies were pooled for meta-analysis, with a random effects model used to
calculate between-group mean differences and 95% confidence intervals (CIs). Data
were analyzed according to the duration of follow-up (short-term, </=8wk
postrandomization; medium-term, >2mo to 12mo; long-term, >12mo). Interventions
were associated with small to moderate improvements in pain at short-term (mean
difference , -5.31; 95% CI, -8.06 to -2.56) and medium-term (mean difference,
-7.92; 95% CI, -12.37 to -3.48) follow-up. Improvements in function were observed
at short-term (mean difference, -6.47; 95% CI, -12.00 to -0.95), medium-term
(mean difference, -9.31; 95% CI, -14.00 to -4.61), and long-term (mean
difference, -5.22; 95% CI, -7.21 to -3.23) follow-up. CONCLUSIONS: Evidence of
fair methodological quality suggests that walking is associated with significant
improvements in outcome compared with control interventions but longer-term
effectiveness is uncertain. With the use of the U.S. Preventive Services Task
Force system, walking can be recommended as an effective form of exercise or
activity for individuals with chronic musculoskeletal pain but should be
supplemented with strategies aimed at maintaining participation. Further work is
required for examining effects on important health-related outcomes in this
population in robustly designed studies.
