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).
