Reliability and validity of electrogoniometry measurement of lower extremity movement

Abstract: Objectives: To establish the reliability, accuracy and concurrent validity of electrogoniometers for measuring extreme lower extremity movements.Study design: Reliability, accuracy and validity study.Methods: This project employed two experiments. Investigation I determined electrogoniometer accuracy compared to a digital protractor. Investigation II compared electrogoniometers to a criterion measure, motion analysis, in sagittal plane dance movements in 17 dancers. Intraclass correlation coefficients (ICC) and standard error of measurement (SEM) were calculated for hip, knee, and ankle sagittal plane angular displacements.Results: In Investigation I, electrogoniometer to protractor correlations were high (r ≥ 0.998, SEM ≤3.65°). In Investigation II, instrument and intra-rater reliability correlations were high (r ≥ 0.983 and r ≥ 0.972, SEM ≤ 3.49° and ≤4.48°), as were concurrent validity correlations (r ≥ 0.949, SEM ≤6.80°) to motion analysis. Conclusions: This error may be acceptable for lower extremity...

Optimal Low-Density Lipoprotein Cholesterol Lowering—Morning Versus Evening Statin Administration:

Abstract: Objective:To determine the best time to administer statins for optimal lowering of low-density lipoprotein cholesterol (LDL-C) by reviewing the clinical evidence evaluating the chronobiologic effects of morning versus evening statin administration.Data Sources:Using the MeSH terms HMG-CoA reductase inhibitors, statins, morning and evening dosing, and clinical trials, a literature review was conducted to identify articles in MEDLINE (1966–December 2006), International Pharmaceutical Abstracts (1970–Deccmber 2006), and IOWA Drug Information Systems (1985–December 2006).Data Synthesis:Seven English-language studies evaluating morning and evening statin administration were identified and evaluated. Based on the available data, simvastatin demonstrated a pronounced LDL-C percentage reduction with evening closing. Although not statistically significant, a trend in the LDL-C percentage reduction favoring evening statin administration was noted with lovastatin, pravastatin, and rosuvastatin. Atorvastatin demonstr...

Short-term functional and clinical outcomes after ACL reconstruction with hamstrings autograft: transtibial versus anteromedial portal technique.

Abstract: Several studies have suggested that drilling the femoral tunnel through an anteromedial arthroscopic portal during anterior cruciate ligament reconstruction allows more anatomic placement of the graft. However, no studies have investigated whether the anteromedial approach results in better outcomes compared to the traditional transtibial drilling approach when a hamstring autograft is used. The purpose of the present study is to investigate short-term functional and clinical outcome differences between male patients recovering from anterior cruciate ligament reconstruction with a hamstring autograft using the transtibial femoral tunnel drilling approach versus the anteromedial approach. Lysholm score, functional test and isokinetic data were collected at 3 and 6 months after surgery in 51 male patients who received a standardized rehabilitation in a large outpatient facility. Multivariate and univariate analyses of variance were used to assess group, time and interaction effects. All outcomes except isokinetic knee flexion at 180°/s improved from 3 to 6 months for both groups (p ≤ 0.05). The anteromedial approach group had better Lysholm scores at 3 months (p ≤ 0.05) and better performance in the timed lateral movement functional tests at 3 and 6 months (p ≤ 0.05). No other comparisons were significant (n.s). Both groups had comparable outcomes on most measures. The differences in the Lysholm score and lateral movement functional tests may suggest a quicker return of function and performance for the anteromedial approach group. Clinicians should take into consideration the surgical technique as they progress patients recovering from ACL reconstruction through the different phases of the rehabilitation protocol. Therapeutic study, Level II.

Teaching for higher levels of thinking: developing quantitative and analytical skills in environmental science courses

Abstract: Professionals with strong quantitative and analytical skills are essential to understanding and responding to current environmental challenges. The goal of this study was to promote and evaluate the development of data analysis (DA) skills in undergraduate students through targeted interventions in environmental science courses. We developed materials to promote practice, instruction, and assessment of four core DA dimensions: the ability to make appropriate calculations, convert data to graphical representations, interpret graphical or mathematical information, and draw conclusions based on the analysis of data. We integrated two conservation exercises as pre/post assessment tools, flanking differentiated teaching interventions, into selected science courses and used a standardized rubric to measure students' performance level. We found that students improved their DA skills in a single semester, but the level of improvement varied across skill dimensions. Students struggled with dimensions that require higher levels of thinking such as data interpretation and drawing conclusions. The use of additional exercises targeting these dimensions and alternative practices might enhance gains. Importantly, students also gained content knowledge in ecological principles while developing skills, and demonstrated an increase in self-confidence with their DA skills. Our approach and open-access materials can be integrated into existing courses to develop and assess data skills in undergraduate learners.
