“…A contributing factor could be that the examiners in our study were familiar with the test method since they used the tests in their clinical work and had undergone a training session prior to the assessments. The importance of experience and standardization has also been pointed out by others [6,11]. Notably, there was a lower agreement between occasions 1 and 2 than between Examiners A and B, especially on patients' injured side ( Table 3).…”

Anterior cruciate ligament injury (ACL) is associated with mechanical instability and defective neuromuscular function, and can lead to further injury, increased joint loading and osteoarthritis. Patients with ACL injury demonstrate altered postural orientation, manifested as observable "substitution patterns" (SPs) but no one has applied a clinically useful method to systematically study postural orientation in these patients. Here, we investigated the presence of such patterns in 24 adults with ACL injury and in 49 controls, in parallel with the development and a first evaluation of a new test battery, test for SPs. The rationale behind the Test for SPs was to characterize postural orientation as the ability to maintain appropriate relationships between body segments and environment during weight-bearing movements. In this first study, patients displayed SPs more frequently and/or more clearly on their injured, but also their uninjured side than did controls. Inter-rater and intra-rater reproducibility was good at a group level. Future studies of validity, responsiveness and including other subgroups of patients with ACL injury will have to prove if the Test for SPs can be used in the diagnostics of defective neuromuscular function following knee injury, when planning and carrying out training and rehabilitation and when deciding appropriate time to return to activity and sports after ACL injury.

“…Eastlack et al 10 identified that a lack of standardization of rater training had led to poor rater reliability in their study. We, therefore, provided the same indepth training to all of our raters, giving them ample opportunity to practice and to ask questions prior to starting.…”

“…We built our simple approach on the foundational work of other groups, 5,10,23,38 which was a key factor in achieving high rater agreement. Specifically, we developed explicit rating criteria incorporating easily discernible anatomical landmarks (the patella and the first toe), based on recommendations by Chmielewski et al, 5 who had poor results with more ambiguous rating criteria such as "good," "fair," and "poor."…”

f all athletic knee injuries, an anterior cruciate ligament (ACL) rupture is the most devastating, resulting in the greatest time lost from sport. 8 The ACL plays a vital role in the normal function and stability of the knee, and individuals wishing to return to sport after rupture are encouraged to consider reconstructive surgery. 29 Those that opt Nonexperimental methodological study.To determine the interrater and intrarater reliability and validity of using observational risk-screening guidelines to evaluate dynamic knee valgus.A deficiency in the neuromuscular control of the hip has been identified as a key risk factor for noncontact anterior cruciate ligament (ACL) injury in postpubescent females. This deficiency can manifest itself as a valgus knee alignment during tasks involving hip and knee flexion. There are currently no scientifically tested methods to screen for dynamic knee valgus in the clinic or on the field.Three physiotherapists used observational risk-screening guidelines to rate 40 adolescent female soccer players according to their risk of ACL injury. The rating was based on the amount of dynamic knee valgus observed on a drop-jump landing. Ratings were evaluated for intrarater and interrater agreement using kappa coefficients. Sensitivity and specificity of ratings were evaluated by comparing observational ratings, with measurements obtained using 3-dimensional (3-D) motion analysis.Kappa coefficients for intrarater and interrater agreement ranged from 0.75 to 0.85, indicating that ratings were reasonably consistent over time and between physiotherapists. Sensitivity values were inadequate, ranging from 67% to 87%. This indicated that raters failed to detect up to a third of "truly high-risk" individuals. Specificity values ranged from 60% to 72%, which was considered adequate for the purposes of the screening.Observational risk screening is a practical and cost-effective method of screening for ACL injury risk. Rater agreement and specificity were acceptable for this method, but sensitivity was not. To detect a greater proportion of individuals at risk of ACL injury, coaches and clinicians should ensure that they include additional tests for other high-risk characteristics in their screening protocols.Prognosis, level 4.

Gait is a complex sequence of movements so that it is very hard to analyze in clinic.Children with cerebral palsy have lots of different type of gait abnormalities. There is no clinically satisfied and reliable gait assessment tool for analyzing gait problem in cerebral palsy. The purpose of the review was to determine the reliability of clinically available video based observational gait analysis on children with spastic hemiplegics and diplegics and to investigate how they can be used in clinical practice as a standard examination tool.The review results showed that clinically available methods have moderate level reliability for between rater reliability and moderate to advance level reliability for within rater reliability. This review suggested that between rater reliability is high enough to use it in clinical practice but within rater reliability needs to be improved by the feature studies.
