TL;DR: The excellent reliability and previously demonstrated validity of the single-camera system along the anterior-posterior axis indicates that single-Camera motion analysis may be a valid surrogate for clinically accepted manual measurements of performance in the horizontal plane, but this single- camera 3D motion analysis system is likewise reliable, but inaccurate, for vertically oriented performance measurements.
Abstract: Background Previous reliability investigations of single-camera three dimensional (3D) motion analysis systems have reported mixed results. Purpose The purpose of the current study was to determine the intra- and inter-rater reliability of a single-camera 3D motion analysis system for subject standing height, vertical jump height, and broad jump length. Study design Experimental in vivo reliability study. Participants Twelve subjects (age 20.6 ± 4.9 years) from a cohort that included high school to adult athletes who participated in sports at a recreational or competitive level entered and completed the study. Performance measurements were collected by a single-camera 3D motion analysis system and two human testers for standard clinical techniques. Inter- and intra-class correlation coefficients (ICC (2,k), ICC (2,1)) were determined. Result Intra-tester and inter-tester reliability were excellent (ICC ≥ 0.935) for single-camera system measured variables. Single-camera system measurements were slightly more reliable than clinical measurements for intra-tester ratings (ICC difference 0.020) for the standing broad jump. Single-camera system measurements were slightly less reliable than clinical measures for both intra- and inter-specimen standing height (mean ICC difference 0.003 and 0.043, respectively) and vertical jump height (mean ICC difference 0.017 and 0.036, respectively). Conclusions The excellent reliability and previously demonstrated validity of the single-camera system along the anterior-posterior axis indicates that single-camera motion analysis may be a valid surrogate for clinically accepted manual measurements of performance in the horizontal plane. However, this single-camera 3D motion analysis system is likewise reliable, but inaccurate, for vertically oriented performance measurements. Level of evidence 2b.

TL;DR: Both the upper and lower twist tests had reliability acceptable enough to warrant implementation in clinical practice, Nonetheless, these tests should not be applied without considering the patient's symptoms and complaints.
Abstract: The purpose of this study was to develop reliable manual tests to diagnose reduced subtalar movement after ankle inversion trauma. Two physiotherapists blinded to the clinical data examined 27 participants (15 with ankle inversion trauma). For this study, a manual test programme was performed with two newly developed tests, an upper and lower twist test, as well as previously described tests for active and passive plantarflexion, and active and passive dorsiflexion. The intra-rater reliability on the upper and lower twist tests ran from 0.70 to 1.00 (Kappa coefficients). The inter-rater reliability of the upper and lower tests ranged from 0.35 to 0.48 (Kappa coefficients). The intra-rater reliability for the other four tests ran from 0.27 to 0.70 (Kappa coefficients) and the inter-rater-reliability ranged from 0.17 to 0.49 (Kappa coefficients). In conclusion, both the upper and lower twist tests had reliability acceptable enough to warrant implementation in clinical practice. Nonetheless, these tests shou...

TL;DR: The BPNT can reliably and accurately quantify outcomes in neural mobility scoring and excellent inter- and intrarater reliability and accuracy levels may allow clinicians to correctly identify BPNT positions regardless of their professional experience or geographic location.

TL;DR: This study demonstrates that FM® assessment procedures have a high reliability even if applied by practitioners with basic experience and can improve pain and ROM in individuals with primary coxarthrosis.
Abstract: An inter and intra rater reliability (INTERR and INTRAR) study was designed. 71 subjects, with primary hip coxarthrosis, were included and randomly divided in a study group (SG= 36) and a control g...
