Relationship Between Fear of Movement and Physical Activity in Patients With Cardiac, Rheumatologic, Neurologic, Pulmonary, or Pain Conditions: A Systematic Review and Meta-Analysis.

OBJECTIVE

Physical activity contributes to the primary, secondary, and tertiary prevention of multiple diseases. However, in some patients, fear of movement may induce avoidance behaviors and reduce engagement in physical activity. This study aims to examine whether this fear of movement is negatively associated with physical activity across several health conditions and what factors may influence this relationship.

METHODS

Five databases were searched for studies including both a measure of fear of movement and physical activity. Two reviewers screened articles for inclusion, assessed risk of bias, and extracted data from each study. Pearson product-moment correlations were pooled from eligible studies using the generic inverse pooling and random effects method to examine the relationship between fear of movement and physical activity.

RESULTS

Seventy-four studies were included in the systematic review and 63 studies (83 estimates, 12,278 participants) in the main meta-analysis. Results showed a negative correlation between fear of movement and physical activity (r = -0.19 [95% CI = -0.26 to -0.13]; I2 = 85.5%). Funnel plot analysis showed evidence of publication bias, but p-curve analysis suggested that our results could not be caused by selective reporting. A subgroup meta-analysis showed that the correlation was statistically significant in patients with cardiac, rheumatologic, neurologic, or pulmonary conditions but not in patients with chronic or acute pain.

CONCLUSIONS

Our results suggest that higher levels of fear of movement are associated with lower levels of physical activity in several health conditions that are not necessarily painful.

IMPACT

Fear of movement should be dissociated from pain and considered in relation to specific health conditions when implementing exercise therapy. Fear of movement may have prognostic and therapeutic implications in patients for whom physical activity contributes to prevent recurrence or worsening of their condition.
