The association of psychological variables and outcome in tendinopathy: a systematic review ABSTRACT Objective: Fear, anxiety, depression, distress and catastrophisation are all factors known to affect pain and disability levels. To date, the association of such psychological factors has yet to be established in tendinopathy. Therefore, the purpose of this paper was to determine if psychological variables are associated with tendinopathy and whether any such variables may be associated with pain and disability outcomes in conservative management of tendinopathy.Design: A systematic review was undertaken and included studies were appraised for risk of bias using the Newcastle Ottawa Scale. Due to heterogeneity of studies, a qualitative synthesis was undertaken.Data sources: An electronic search of MEDLINE, CiNAHL, SPORTDiscus, PsycINFO, EMBASE and PsycARTICLES was undertaken from their inception to April 2016.Eligibility criteria for selecting studies: Any study design that incorporated psychological measures and clinical outcomes using participants with tendinopathy.Results: Ten articles describing nine studies and 1108 participants were included. Conflicting evidence exists regarding the association of anxiety, depression and lateral epicondylalgia (LE). Strong evidence suggests LE is not associated with kinesiophobia. Moderate evidence links catastrophisation and distress with LE. Moderate evidence suggests distress is not associated with rotator cuff tendinopathy, but kinesiophobia and catastrophisation are. Limited evidence suggests patella tendinopathy is not associated with anxiety or depression and kinesiophobia may be linked with suboptimal outcomes in Achilles tendinopathy.
Summary/conclusions:Tendinopathy requires an individualised approach to management. Clinicians should consider using validated screening tools for the presence of psychological variables as a part their holistic management.
What are the new findings Psychological variables may be associated with tendinopathy and a suboptimal outcome Multi-dimensional factors influence the development and maintenance of pain and disability in tendinopathy The underlying factors for the presence of these variables and their amenability to change warrant further investigation How might it impact on clinical practice in the near future Tendinopathy management should include an individualised, holistic assessment Management strategies may need to be adapted to address individual psychological variables and any underlying cognitive barriers.
