Risk Factors to Persistent Pain Following Musculoskeletal Injuries: A Systematic Literature Review.

BACKGROUND

Musculoskeletal (MSK) injury is one of the major causes of persistent pain.

OBJECTIVE

This systematic literature review explored the factors that lead to persistent pain following a MSK injury in the general population, including athletes.

METHODS

A primary literature search of five electronic databases was performed to identify cohort, prospective, and longitudinal trials. Studies of adults who diagnosed with a MSK injury, such as sprains, strains or trauma, were included.

RESULTS

Eighteen studies involving 5372 participants were included in this review. Participants' ages ranged from 18-95 years. Most of the included studies were of prospective longitudinal design. Participants had a variety of MSK injuries (traumatic and non-traumatic) causing persistent pain. Multiple factors were identified as influencing the development of persistent pain following a MSK injury, including high pain intensity at baseline, post-traumatic stress syndrome, presence of medical comorbidities, and fear of movement. Scarcity of existing literature and the heterogeneity of the studies made meta-analysis not possible.

CONCLUSIONS

This systematic review highlighted factors that might help predict persistent pain and disability following MSK injury in the general population, including athletes. Identification of these factors may help clinicians and other health care providers prevent the development of persistent pain following a MSK injury.
