摘要

Background and Purpose: Jumping is a common physical activity in daily life; however, aberrant landing alignment will increase the risk of knee injury. Real-time feedback and post-event video feedback interventions are both considered useful to mitigate biomechanical risk factors. It is so far unknow whether the two types of feedback influence the biomechanical performance during landings. Thus, this review aims to assess the effectiveness of using real-time feedback and video feedback for correcting landing movement in females, who carry additional risk of knee injuries. Methods: PubMed and Scopus were used to search relevant articles in April 2022. The searching keywords include (a) immediate or real time or video; (b) feedback or biofeedback or postfeedback; and (c) landing. Quality of evidence was assessed using the Methodological Index for Non-Randomized Studies (MINORS) criteria for non-randomized studies and the Physiotherapy Evidence Database (PEDro) scale for randomized controlled studies. A random-effect model was set to analyze the pooled effect size. Results: Nine studies were eligible, including five of real-time feedback studies and four of video feedback studies, based on the selection criteria. Analysis of pooled outcomes indicated that real-time feedback had large effect on decreasing hip extension moment during landing from baseline to posttest (SMD = 0.85, 95% CI = 0.01, 1.70, p = 0.05); video feedback had large effect on increasing knee flexion angle (SMD = 1.73, 95% CI [0.24, 3.22], p = 0.02), and increasing hip flexion angle (SMD = 1.20, 95% CI [0.23, 2.16], p = 0.01) during landing from baseline to posttest and large effect on increasing knee flexion angle during landing comparing with control group (SMD = -1.81, 95% CI [-3.62, 0], p = 0.05). Conclusion: Both real-time feedback and video feedback intervention may decrease the biomechanical risk of knee injuries during landing in females. However, there is no clear evidence indicating that real-time feedback outperformed video feedback in injury prevention. However, future studies will be needed to confirm our current findings and to compare the effectiveness between the two types of feedback. Clinical Relevance: The results can be used to develop training programs to decrease the risk of knee injury during landing in females, especially in athletes.
