Abstract：
BACKGROUND: Clinical methods for assessing quality of movement and functional tests are important to clinicians. Typical deviations from normal kinematics during the clinical test of Forward Step Down Test (FSDT) are pelvic tilt and hip adduction which are associated with the risk of knee pain.
OBJECTIVE: (1) to examine the correlation between clinical assessment of the FSDT and joint angle measurements of pelvis, hip, knee and ankle joints in males and females; (2) to examine the differences in joint angles between individuals rated as good, fair or poor in a FSDT performance test.
METHODS: Ninety-two healthy individuals performing FSDT were video-taped with two-dimensional digital video cameras. The clinical assessment of the FSDT was rated by two experienced physical therapists as good, fair, or poor based on a Crossley et al. (2011) validated scale. Measurements of pelvic drop, hip adduction and knee valgus were taken using Image J software.
RESULTS: Out of 177 lower limbs, 74 (37 in each limb) were clinically rated as \"good/fair\" (41.80%) while 103 (52 in the dominant leg and 51 in the non-dominant leg) were rated as \"poor\" (58.19%). No significant differences were observed between dominant and non-dominant legs or between males and females in clinical rating of the FSDT. Pelvic drop angle was significantly higher and hip adduction angle was significantly lower for \"poor\" clinical rating compared to \"good/fair\" in both dominant and non-dominant legs (p < 0.001) in males and females. Females demonstrated higher pelvic drop, lower hip adduction and higher knee valgus angles compared with males (p < 0.05).
CONCLUSIONS: This study showed that the clinical rating of FSDT is correlated with joint angle measurements suggesting that this assessment can be utilized in clinical practice. Individuals with poor quality performance of FSDT showed higher pelvic drop and hip adduction movement. Further studies examining different populations with diverse disorders or pathologies are essential.

摘要：
背景：评估运动质量和功能测试的临床方法对临床医生很重要。在正向降压测试（FSDT）的临床试验中，与正常运动学的典型偏差是骨盆倾斜和髋关节内收，这与膝盖疼痛的风险有关。
目的：（1）检查FSDT的临床评估与骨盆关节角度测量之间的相关性，臀部,男性和女性的膝关节和踝关节；（2）检查被评为良好的个体之间的关节角度差异，在FSDT性能测试中公平或较差。
方法：使用二维数码摄像机对92名进行FSDT的健康个体进行视频录制。两名经验丰富的物理治疗师将FSDT的临床评估评为良好，公平,或基于Crossley等人的穷人。(2011)验证量表。骨盆滴的测量，使用ImageJ软件采集髋关节内收和膝关节外翻。
结果：在177个下肢中，74（每条肢体37条）在临床上被评为“良好/一般”（41.80％），而103（优势腿52条，非优势腿51条）被评为“差”（58.19％）。在FSDT的临床评级中，优势腿和非优势腿之间或男性和女性之间没有观察到显着差异。在男性和女性中，与优势腿和非优势腿的“良好/正常”相比，“差”的临床评分明显较高，髋关节内收角度明显较低（p<0.001）。女性表现出更高的骨盆下降，与男性相比，髋关节内收较低，膝关节外翻角度较高（p<0.05）。
结论：这项研究表明，FSDT的临床评分与关节角度测量值相关，表明该评估可用于临床实践。FSDT质量表现较差的个体表现出更高的骨盆下垂和髋关节内收运动。进一步的研究检查具有不同疾病或病理的不同人群是必不可少的。
