“…The MDD 90 used in the present study corresponds to the upper bound of the random variation that 90% of stable patients generate when tested on multiple occasions (26). The formula for MDD 90 is MDD=1.65*SEM* (26,27). The pelvic asymmetry ratios are the ratio of pelvic postural parameters between left and right sides, which are affected by the measured values of the pelvic postural parameters.…”

KEYWORDSpelvic asymmetry, low back pain, photographic assessment, pelvic posture 3 Abstract Background Empirical evidence that identifies the pelvic asymmetry in which movement plane that contribute to non-specific chronic low back pain (NCLBP) is currently lacking.Objective To establish the reliability of the Global Postural System (GPS) in assessing pelvic asymmetry and identify the association between pelvic asymmetry parameters and the occurrence of NCLBP in young adults.Design A cross-sectional, regression study.Methods People who aged between 18 and 30 and were diagnosed with NCLBP were recruited.Healthy individuals who were matched for age, gender, and education level were recruited as controls and for the reliability analysis. Reliability was assessed by the ICC (3, k), standard error and minimal detectable difference. Bivariate correlation analysis and logistic regression analysis were used to determine the risk factors.Results Twenty-eight healthy participants and 28 people with NCLBP were recruited. Moderate to excellent ICCs were observed for the inter-rater and intra-rater reliability of most postural parameters.The bivariate correlation analysis indicated that age, body mass index and pelvic asymmetry parameters were related to the occurrence of NCLBP. Pelvic angle asymmetry (odd ratio=1.17), and asymmetry of the distance between the posterior superior iliac spine and the floor (odd ratio=1.21)were significant risk factors of NCLBP.Limitation This study did not explore the causal relationship between pelvic asymmetry in the sagittal plane/pelvic asymmetry in the transverse plane and the occurrence of NCLBP. The interpretation of the results may not be generalized beyond the sample population.Conclusions The GPS is a reliable method to assess pelvic asymmetry in a clinical setting. The pelvic asymmetry parameters obtained from the GPS are likely to assist in the early identification of the potential occurrence of NCLBP.

“…Between-day reliability for kinematic variables during walking and running has been reported with ICC's (without 95% CI's) in the range of 0.51-0.72 (Alenezi, et al, 2016); 0.54-0.93 (Ferber, et al, 2002) and 0.644 -0.993 (Milner & Brindle, 2016). In comparison to between-day reliability, within-day reliability for kinematic variables is typically greater: 0.63-0.94 (Alenezi, et al, 2016); 0.92-0.99 (Ferber, et al, 2002) and 0.881 -0.994 (Milner & Brindle, 2016). Therefore, the between-(0.739 -0.989) and…”

Sprint velocity decreases on the bend when compared with the straight, therefore understanding technique during bend sprinting could have important implications for aiding race performance. Few bend sprinting studies have used optoelectronic cameras to investigate kinematic variables. Limited published evidence regarding the reliability of marker sets in conditions representative of elite bend sprinting makes model selection difficult. Therefore, a test-retest protocol was conducted to establish the reliability and minimum detectable difference of a lower limb and trunk marker set during bend sprinting (radius: 36.5 m). Six participants completed five, 60 m trials at maximum effort, with data collected at 38-45 m. This was repeated 2-7 days later. Spatio-temporal (e.g. contact time) and kinematic variables (e.g. peak joint angles) were evaluated. Intraclass correlation coefficients (ICC) were used to determine the between-and within-day reliability. Between-day reliability (ICC 3, k) was fair to excellent for all variables. Compared to between-day, within-day reliability demonstrated stronger agreement for the majority of variables. Thus, same-day data collection is preferable. It has been established that the marker set is reliable for future use. In addition, the minimal detectable difference was calculated which serves as useful reference for future research in bend sprinting. (Word count: 200)
