Due to its association with the risk of falling and consequent injury, the importance of agility is widely recognized, but no study so far has examined the different facets of agility in an untrained/clinical population. The aim of this study was to evaluate the reliability, validity, and correlates of newly developed tests of non-planned agility (NPA) and pre-planned agility (PPA) in an untrained/clinical sample.
The sample comprised 38 participants older than 40 years (22 females, age: 56.1 ± 17.3 years, height: 170.4 ± 10.8 cm, mass: 82.54 ± 14.79 kg) who were involved in a rehabilitation program following total knee arthroplasty and knee arthroscopy. Variables included age, gender, type of surgery, history of fall, anthropometrics/body composition, and newly developed tests of NPA and PPA.
The results showed the high inter-testing- (ICC > 0.95, CV < 9%), and intra-testing-reliability (ICC > 0.96, CV < 9) of the newly developed tests. PPA and NPA were found to be valid in differentiation between age groups (>50 yrs. vs. <50 yrs.), and genders, with better performance in younger participants and males. Only NPA differentiated participants according to type of surgery, with better performance in those who had arthroscopic surgery, than those who had total knee arthroplasty. No differences in NPA and PPA were established between groups based on fall-history. In females, the body mass (Pearson's = 0.58 and 0.59, < 0.001) and body fatness (Pearson's = 0.64 and 0.66, < 0.001) were negatively correlated, while the lean body mass (Pearson's = 0.70 and 0.68, < 0.001) was positively correlated with PPA and NPA. The NPA and PPA were highly correlated (Pearson's = 0.98, < 0.001).
We found that the proposed tests are reliable when evaluating agility characteristics in an untrained/clinical population after knee arthroplasty/arthroscopy. Further evaluation of the specific validity of the proposed tests in other specific subsamples is warranted.
由于敏捷性与跌倒风险及随之而来的损伤相关，其重要性已得到广泛认可，但迄今为止尚无研究在未经训练的/临床人群中考察敏捷性的不同方面。本研究的目的是评估新开发的非计划性敏捷性（NPA）测试和计划性敏捷性（PPA）测试在未经训练的/临床样本中的信度、效度及相关性。
样本包括38名年龄超过40岁的参与者（22名女性，年龄：56.1±17.3岁，身高：170.4±10.8厘米，体重：82.54±14.79千克），他们参与了全膝关节置换术和膝关节镜检查后的康复项目。变量包括年龄、性别、手术类型、跌倒史、人体测量学/身体成分，以及新开发的NPA和PPA测试。
结果显示新开发测试具有较高的测试间信度（组内相关系数>0.95，变异系数<9%）和测试内信度（组内相关系数>0.96，变异系数<9）。发现PPA和NPA在区分年龄组（>50岁与<50岁）和性别方面有效，年轻参与者和男性表现更好。只有NPA能根据手术类型区分参与者，接受关节镜手术的参与者比接受全膝关节置换术的参与者表现更好。基于跌倒史的组间在NPA和PPA方面未发现差异。在女性中，体重（皮尔逊相关系数分别为0.58和0.59，P<0.001）和体脂（皮尔逊相关系数分别为0.64和0.66，P<0.001）与PPA和NPA呈负相关，而瘦体重（皮尔逊相关系数分别为0.70和0.68，P<0.001）与PPA和NPA呈正相关。NPA和PPA高度相关（皮尔逊相关系数为0.98，P<0.001）。
我们发现，在评估膝关节置换术/关节镜检查后未经训练的/临床人群的敏捷性特征时，所提出的测试是可靠的。有必要进一步评估所提出测试在其他特定亚样本中的具体效度。
