Gait Retraining With Real-Time Visual Feedback to Treat Patellofemoral Pain in Adult Recreational Runners: A Critically Appraised Topic.

Clinical Scenario: Patellofemoral pain (PFP) is a common knee injury in recreational adult runners, possibly caused by faulty mechanics. One possible approach to reduce this pain is to retrain the runner's gait. Current research suggests that no definitive gold standard treatment for PFP exists. Gait retraining utilizing visual feedback may reduce PFP in both the short and long term. Clinical Question: In adult runners diagnosed with PFP, does gait retraining with real-time visual feedback lead to a decrease in pain? Summary of Key Findings: A literature search was performed; 3 relevant studies utilizing gait retraining with visual feedback, pain level as an outcome measure, and follow-up measures of at least 1 month after the intervention were included. All the included studies reported a decrease in short- and long-term pain for participants following visual feedback gait retraining. In addition, biomechanical measures related to PFP, including peak hip adduction angle and the angle of contralateral pelvic drop, improved after the completion of the intervention. Clinical Bottom Line: There is level 2 evidence supporting the implementation of 8 sessions over 2 weeks of visual feedback gait retraining as a means of treating patients diagnosed with PFP. Based on current available evidence, clinicians should identify faulty mechanics of patients and implement a protocol of increasing real-time visual feedback over the first 4 sessions and decreasing visual feedback over the final 4 sessions. Strength of Recommendation: Level 2.

Using the Selective Functional Movement Assessment for the Evaluation of Dancers' Functional Limitations and Dysfunctions: A Critically Appraised Topic.

Clinical Scenario: Dancers participate in a functionally demanding activity. Athletic participation typically requires the completion of a preparticipation examination, which involves a functional movement screen offering insight into potential injury recognition. The Selective Functional Movement Assessment (SFMA) was created to measure the status of movement-pattern-related pain and dysfunction using regionally interdependent movement to aggravate symptoms and exhibit limitations and dysfunctions. Still, a functional assessment has not been identified to recognize potential dysfunctions or limitations in this population. Clinical Question: Does the use of the SFMA improve overall evaluation of dancers by providing more information on a dancer's overall functional ability and limitations? Summary of Key Findings: The literature search discovered 12 studies and 3 books in which 4 studies were included (2 case reviews, 1 case report, and 1 original research study) based on the inclusion and exclusion criteria. Three of the studies provided clinical case studies utilizing the SFMA to improve the patient's dysfunctions, whereas 1 study examined the intrarater and interrater reliability of the SFMA. In 3 studies, participants displayed less movement dysfunction. The authors from 3 of the studies agreed the SFMA was a valuable tool for clinicians to use during evaluations, as it provided a more holistic view of the patient, discovering dysfunctional movement patterns that may better identify the source of injury. Clinical Bottom Line: Low-quality evidence, defined as poorly designed case studies, case series, and cohort studies, exist that supports improvement of overall evaluations when utilizing the SFMA. Although the studies were considered low-quality evidence, each included study displayed an effective use of the SFMA as an overall evaluation that correctly identified dysfunctional movement patterns. Strength of Recommendation: Grade C evidence exists that the SFMA contributes to the functional evaluation used in dancers.
