These grades did not contribute towards their end-of-rotation score and were used as feedback only i.e. formative and not summative.
The correlation of mental rotation score (MRS) and compatibility effect using RTs was not significant (r = .04, p = .81).81
The team finished the rotation scoring 49.4, and junior Kyla Ross earned her second perfect 10 of the season on beam.
There were no significant partial correlations with symmetry total score (r = 0.16) or RT (r = 0.06) and mental rotation score (r = −0.02) or RT (r = −0.11).
For estimation of the GH-JRC, various methods have been introduced and used such as regression models [3], [4], spherical-fit [5], instantaneous helical axis (IHA) [6], [7], [8], symmetrical center of rotation (SCoRE) [2], [9], bias compensated [10], and least-square methods [11], [12].
The goal of this paper is to compare two widely used functional methods, namely the instantaneous helical axis (IHA) and symmetrical center of rotation (SCoRE) methods, for estimating the GH-JRC in vivo for patients with implanted shoulder hemiarthroplasty.
All the differences, apart from hand to mouth score, between preoperative and postoperative values were found significant according to the Student's t-test (t = -2.53 p = 0.035 for abduction score, t = -3.592 p = 0.007 for external rotation score, t = -4.4 p = 0.002 for hand to head score and t = 2.8 p = 0.023 for hand to back score).
Only animals (26) that exhibited a mean ipsilateral rotation score of seven or more complete body turns per minute were included in the study.
All the differences between preoperative and postoperative values were found significant according to the Student's t-test (t = -17.14 p = 0.000 for abduction score, t = -12.04 p = 0.000 for external rotation score, t = -13.06 p = 0.000 for hand to head score, t = 2.372 p = 0.023 for hand to back score and t = -7.361 p = 0.000 for hand to mouth score).
Analysis: The primary outcome, the difference between pre and post rotation scores was compared between residents in the no order set period and residents in the order set period, using univariate linear regression.
Strengths include use of pre- and post- rotation scores within the same subject, reducing inter-subject variability, an objective questionnaire development process, and strong measures of questionnaire construct validity.
