We evaluated the reliability of spatio-temporal variables and bod

We evaluated the 123 reliability of spatio-temporal variables and body angles (lower-limb joints, trunk and pelvis angles) during two sessions of 3DGA using intra-class correlation coefficients (ICC). The minimum number of trials needed to overcome intrinsic variability was evaluated using an exponential fit model and the Bland and Altman coefficient of repeatability AR-13324 concentration (CoR). The accuracy of measurement was evaluated using a manual goniometer and the recording of 18 different angles.\n\nResults: Spatio-temporal variables

and most of the kinematic joint and trunk angles calculated demonstrated good to excellent reliability (ICC from 0.77 to 0.97). This was not the case for pelvic angles. The fitting model combined with the CoR showed that 5-10 trials are sufficient to obtain good reliability [ICC > 0.7; CoR < 2 standard deviation (SD)] for most of the spatio-temporal variables. All body angles showed good reliability (ICC > 0.7) and low CoR (< 2 SD) after five trials except for the pelvic angles. The reliability of marker positioning was found to be good (ICC > 0.7) to excellent (ICC > 0.9). Differences between angles measured using 3DGA and angles measured with a manual goniometer were found to be less than one percent.\n\nConclusion: The present study shows that most of variables obtained using

3DGA in hip OA patients are reliable. Moreover, for most variables, 5-10 trials are needed to obtain good reliability and to overcome intrinsic variability, rather than 30 or more, thus improving the feasibility selleck products of measurement.

“Objective\n\nTo measure vascular endothelial growth factor (VEGF) levels in aqueous humor, serum, and plasma in diabetic VX-689 and nondiabetic cataractous dogs.\n\nMethods\n\nCanine VEGF was assayed in the plasma and serum of 32 dogs (20 diabetics; 12 nondiabetics) and aqueous humor in 57 eyes of those dogs (39 diabetic; 18 nondiabetic) undergoing phacoemulsification, using a commercial canine VEGF assay. Statistical analysis was performed using Fisher’s PLSD, t-test, and regression analysis to compare values by diabetic status, duration of diabetes, age, weight, gender, left vs. right eye, and blood clarity.\n\nResults\n\nPlasma, but not serum or aqueous humor VEGF values of diabetics were significantly greater than nondiabetics (P = 0.019). Older nondiabetics (10-15 years) had higher plasma VEGF values than younger (0-5 and 5-10 years) dogs (P = 0.0002 and 0.0001, respectively). There was no significant difference in aqueous humor VEGF between left and right eyes in all patients. Serum and plasma, but not aqueous humor, VEGF values in females were significantly higher than males in both groups.\n\nConclusion\n\nSimilar to human diabetic patients, VEGF aqueous humor values in all dogs are significantly higher than blood values.
