Examination of Fear of Re-Injury, Fear Avoidance Beliefs, Physical Activity and Patient-Based and Functional Outcomes after ACL Reconstruction

Grants and Contracts Details

Description

A consequence of participation in physical activity is the risk of musculoskeletal injury. Injury to the anterior cruciate ligament (ACL) is a common injury sustained by physically active individuals. Most individuals undergo ACL reconstruction (ACLR), which includes a lengthy rehabilitation process. About half of patients return to competitive levels of sport after ACLR. Previous literature has suggested that contextual factors, such as fear of re-injury, fear avoidance beliefs, and decreased levels of self-efficacy can influence future engagement in PA, and ultimately affect the patient’s health related quality of life (HRQL) post ACLR. Therefore, the purpose of this study is to examine functional and patient-based outcomes, such as HRQL, fear avoidance-beliefs, fear of re-injury, and self-efficacy, and their correlation to PA levels in individuals with a history of ACLR. We hypothesize that higher levels of fear and decreased levels of self-efficacy will be predictive of lower levels of PA engagement and poorer scores on functional testing. Approximately 40 participants will be enrolled in the study. Each participant will complete a series of functional testing, patient reported outcome measures (PROs), and will also wear a pedometer for a week to track daily step counts. Daily step counts will be utilized to assess PA levels. Separate stepwise-multiple linear regressions analyses will be conducted with PRO scores and functional test scores serving as the predictor variables and PA serving as the dependent variable. Significance will be set a priori at p < 0.05 and Cohen’s f will estimate the effect size of the model. An effect size of >0.15 will be considered clinically significant. All statistical analyses will be conducted with SPSS Version 22 (SPSS, Inc., Chicago IL).
