目的：本研究主要目的為透過文獻回顧研究落地動作錯誤評分系統評估下肢傷害發生的風險。方法：搜尋2009年至2025年的文獻資料庫，包含Pubmed和華藝資料庫，依據文獻篩選標準進行文獻篩選，再依據Quality In Prognosis Studies (QUIPS) 進行文獻研究設計嚴謹性和偏差風險的評估。結果：共納入10篇文獻，全部皆是英文期刊。其中5篇發現LESS分數可以預測下肢傷害的發生，2篇屬於低偏差風險、1篇屬於中偏差風險、2篇屬於高偏差風險；另外5篇發現LESS無法預測下肢傷害的發生，1篇屬於低偏差風險、1篇屬於中偏差風險、3篇屬於高偏差風險。結論：本研究結論LESS是否可以評估下肢傷害的發生的風險，可能還難以下定論。未來可能還需要更多研究使用嚴謹的研究方法，調查LESS分數預測下肢傷害風險的研究。

Purpose: This study aimed to assess the risk of lower limb injuries using a Landing Error Scoring System (LESS) through a literature review. Methods: Literature databases from 2009 to 2025, including PubMed and Airiti Library databases, were searched. Literature was screened according to selection criteria, and the methodological quality of the research was assessed using the Quality in Prognosis Studies (QUIPS). Results: Ten articles, all in English journals, were included. Five articles found that LESS could predict the occurrence of lower limb injuries (two with low risk of bias, one with moderate risk, and two with high risk); the other five, on the other hand, found that LESS could not predict lower limb injuries (one with low risk of bias, one with moderate risk, and three with high risk). Conclusion: This study concludes that whether we could adopt LESS to assess the risk of lower limb injuries remains inconclusive. Further research using rigorous methodologies is needed to investigate the prediction of lower limb injury risk using LESS scores.
