BACKGROUND: Novice nurses, occupational and physical therapist’s injury rates are alarming. OBJECTIVE: To test for differences in peak elbow flexion forces (PEFF) by profession using different forearm positions. METHODS: Entry-level RN, OT, and PT students performed 3-repetitions of standing PEFF in forearm supination, pronation, and neutral. A one-way repeated measures ANOVA determined the forearm position with the greatest PEFF. A one-way ANOVA assessed differences in PEFF between professions. The alpha level was set at p≤0.05 for all analyses. RESULTS: Thirty 30 RN, 25 OT, and 30 PT students (x = 23.27 + /–3.29 yrs.) were studied. A one-way repeated measures ANOVA revealed a significant difference in PEFF between positions (F(2,168) = 144.3, p <  0.0001). A significant (p <  0.0001) pairwise comparison revealed neutral produced the greatest (28.15 + /–12.64 kg) and pronation the least PEFF (17.27 + /–7.40). PEFF was significantly different between position by profession (supination: F(2,82) = 10.14, p <  0.0001; pronation: F(2,82) = 10.33, p <  0.0001; neutral: F(2,82) = 13.39, p <  0.0001). PTs were significantly stronger than OTs and RN students in all forearm positions (p <  0.01). CONCLUSIONS: Neutral PEFF was greatest and PT students demonstrated greater PEFF than OT and RN students.

Background: Range of motion (ROM) asymmetry between sides is one indicator of a positive neurodynamic test, but this has been less well studied for the ulnar nerve. Objective: The purpose of this study was to investigate side-to-side variation in elbow ROM during an ulnar neurodynamic test sequence, including contralateral cervical side flexion, in 40 asymptomatic subjects. Methods: A traditional goniometer was used to measure elbow flexion ROM at two end points, onset of resistance ([Formula: see text]1) and symptom onset ([Formula: see text]1). Two repeated measures of [Formula: see text]1 and [Formula: see text]1 were taken on each side. Results: Reliability for [Formula: see text]1 and [Formula: see text]1 was found to be good (ICC [Formula: see text], SEM [Formula: see text]) with no significant difference in mean ROM between sides. A significant relationship between sides was seen ([Formula: see text] values [Formula: see text]) and [Formula: see text] values [Formula: see text]; this indicates at least 23% of the variance observed in one limb was accounted for by range in the opposite limb. This relationship was slightly stronger for [Formula: see text]1 than [Formula: see text]1. Lower bound scores indicate that intra-individual ROM difference [Formula: see text] for [Formula: see text]1 and 22° for [Formula: see text]1 would exceed normal ROM asymmetry. Conclusion: These findings provide clinicians with background information of ROM asymmetry during the ulnar neurodynamic test.

The Mean

Randomly chosen high school choristers with extensive training in solfège syllables and Curwen hand signs ( N = 38) are asked to sight-sing two melodies, one while using Curwen hand signs and the other without. Out of a perfect score of 16, the mean score with hand signs was 10.37 ( SD = 4.23), and without hand signs, 10.84 ( SD = 3.96). A repeated-measures ANOVA revealed no statistically significant difference, F(1, 37) = .573, p = .454. These findings support the results of five earlier studies; however, because earlier studies were limited to students who were minimally trained in movable solfège syllables and Curwen hand signs, this study expands the knowledge base. Relationships between performance scores and instrumental experience, class grade, sight-singing experience, and hand sign experience were also examined. A pedagogical strategy for linking Curwen hand signs with students' preferred modes of learning (especially the kinesthetic mode) is recommended.

Abstract Objectives The purpose of this study is to determine the effect of topical vitamin C on second-degree burn wounds restoration. This was a clinical trial. The sample size was determined as 30. Participants were selected from patients suffering from second-degree burns who visited the Burn Center of Vaseei Hospital in Sabzevar. Both intervention and control groups targeted one patient.Dressing was changed in a daily manner after cleansing. A topical vitamin C solution was administered on the wounds. The Bates-Jensen Wound Assessment Tool was used to evaluate burn wound parameters in the 1 st , 3 rd , 7 th , and 14 th days of treatment. Data was analyzed using SPSS v.16 and ‘’repeated measures ANOVA. Results The average age of participants was 43.33 ± 11.9 years and 60% of the participants were males and 40% of them were females. The results of repeated measures ANOVA showed a statistically significant difference in mean scores of the wound between the two treatments (P = 0.047), wound healing significantly differed in the two groups and topical vitamin C solution had a significant effect on the acceleration of wound Epithelialization. The administration of topical vitamin C is recommended for epithelialization of second-degree burns.

Introduction: Both prevalent and incident CVD are negatively associated with 25-hydroxyvitamin D (25[OH] D) levels but the existence of a causal mechanism has yet to be determined. Vitamin D (D) supplementation may increase total HDL-c or one of the HDL subclasses; HDL2 and HDL3 and decrease CVD. The effect of D supplementation with HMG-CoA reductase inhibitor use on HDL-c, HDL2, and HDL3 also remains unclear. Hypotheses: We assessed the following two hypotheses; 1) HDL-c, HDL2, or HDL3 levels will increase with D supplementation for 12 weeks versus placebo and 2) HDL-c, HDL2, or HDL3 levels will increase with D supplementation for 12 weeks with HMG-CoA reductase inhibitor use versus without HMG-CoA reductase inhibitor use. Methods: Serum sample data, including 25(OH) D, HDL-c, HDL2, and HDL3 levels, from a randomized double-blinded placebo-controlled trial conducted between 2008 and 2012 were secondarily analyzed. Statistical analyses included Pearson correlation and Repeated-Measures ANOVA. Results: Hypothesis #1; of the 59 participants (mean age=56.0 years), 39 had a deficient (< 20 ng/mL) baseline 25(OH) D level. Hypothesis #2; of the 40 participants (mean age=56.5 years) 23 had a deficient (< 20 ng/mL) baseline 25(OH) D level. Pearson correlation showed 12-week 25(OH) D levels were moderately positively correlated with 12-week HDL-c (0.337, p ≤ 0.05) and 12-week HDL3 (0.356 p ≤ 0.05) levels but not at baseline. Hypotheses #1 and #2; baseline and 12-week levels for HDL-c, HDL2, and HDL3 were moderately to strongly positively correlated with female gender and moderately to strongly negatively correlated with BMI. Some participants did not achieve sufficient 25(OH) D levels. Repeated-Measures ANOVA with one between-subjects factor; group, and one within-subjects factor; time, showed no statistically significant difference in the mean change in HDL-c, HDL2 or HDL3 for D supplementation versus placebo or for D supplementation with versus without HMG-CoA reductase inhibitor use. Conclusions: Future studies may provide more informative results if they include; more participants, deficient 25(OH) D level as an inclusion criteria, and continued D supplementation until sufficiency is attained versus discontinuation after a pre-specified time period.

Even though adaption of the Voodoo Floss Band is gaining momentum, evidence-based literature on its effectiveness remains sparse. The purpose of this quantitative observational design study was to investigate the effects of the Voodoo Floss Band on soft-tissue flexibility and perception of movement. A repeated-measures ANOVA with between-subjects factor demonstrated both groups significantly improved GH flexion range of motion from pretest to post-test but there was not a statistically significant difference between the groups. Perceptions of flexibility increased more for the Voodoo Floss Band group, demonstrating a psychological increase in GH flexion, but not a physical increase.

The Impact

Introduction: Barriers to completing high quality work-based assessments (WBAs) include relational factors such as the episodic and fragmented interaction that often exists between clinical supervisors and trainees. In an effort to increase supervisor-trainee continuity, the Department of Emergency Medicine at the University of Ottawa created Clinical Teaching Teams (CTT) in which a resident and clinical supervisor work matched shifts together throughout the year. The aim of this study was to determine the impact of supervisor-trainee continuity on the quality of assessments documented on Daily Encounter Cards (DECs). Methods: DECs completed by 20 clinical supervisors were collected and sorted into three groups representing differing degrees of supervisor-trainee continuity (Group 1: CTT emergency resident; Group 2: non-CTT emergency resident; Group 3: non-CTT off-service resident). DECs were scored using the Completed Clinical Evaluation Report Rating (CCERR), a 9-item instrument that has been shown to have reliable ratings and the ability to discriminate the quality of completed DECs. Scores were analyzed using a univariate ANOVA with “mean CCERR score” as the dependent variable and “continuity group” and “supervisor” as between-subject variables. The relationship between CCERR scores and number of CTT encounters over time was examined using a repeated measures ANOVA with “encounter number” as the within-subject factor. Results: Mean CCERR scores for the CTT (21.0, SD=5.8), non-CTT (21.9, SD=4.2), and off-service (20.7, SD=4.0) groups differed (p=0.019). A subsequent pairwise comparison demonstrated a statistically significant difference in means between the non-CTT and off-service groups (p=0.04); however, this 1.2 difference on the 45-point CCERR scale is unlikely to be of any educational significance. The number of repeated encounters did not have a statistically significant effect on CCERR scores (p=0.43) indicating that DEC quality did not improve with greater supervisor-trainee interaction. Conclusion: DEC quality as scored by the CCERR was low for all three groups. Increasing supervisor continuity alone did not result in higher quality assessments of clinical performance. Additional research focusing on the educational alliance that develops between supervisor and trainee may hold greater promise.

Speech Recognition In Noise

AbstractPrevious research in cochlear implant (CI) recipients with bilateral severe-to-profound sensorineural hearing loss showed improvements in speech recognition in noise using remote wireless microphone systems. However, to our knowledge, no previous studies have addressed the benefit of these systems in CI recipients with single-sided deafness.The objective of this study was to evaluate the potential improvement in speech recognition in noise for distant speakers in single-sided deaf (SSD) CI recipients obtained using the digital remote wireless microphone system, Roger. In addition, we evaluated the potential benefit in normal hearing (NH) participants gained by applying this system.Speech recognition in noise for a distant speaker in different conditions with and without Roger was evaluated with a two-way repeated-measures design in each group, SSD CI recipients, and NH participants. Post hoc analyses were conducted using pairwise comparison t-tests with Bonferroni correction.Eleven adult SSD participants aided with CIs and eleven adult NH participants were included in this study.All participants were assessed in 15 test conditions (5 listening conditions × 3 noise levels) each. The listening conditions for SSD CI recipients included the following: (I) only NH ear and CI turned off, (II) NH ear and CI (turned on), (III) NH ear and CI with Roger 14, (IV) NH ear with Roger Focus and CI, and (V) NH ear with Roger Focus and CI with Roger 14. For the NH participants, five corresponding listening conditions were chosen: (I) only better ear and weaker ear masked, (II) both ears, (III) better ear and weaker ear with Roger Focus, (IV) better ear with Roger Focus and weaker ear, and (V) both ears with Roger Focus. The speech level was fixed at 65 dB(A) at 1 meter from the speech-presenting loudspeaker, yielding a speech level of 56.5 dB(A) at the recipient's head. Noise levels were 55, 65, and 75 dB(A). Digitally altered noise recorded in school classrooms was used as competing noise. Speech recognition was measured in percent correct using the Oldenburg sentence test.In SSD CI recipients, a significant improvement in speech recognition was found for all listening conditions with Roger (III, IV, and V) versus all no-Roger conditions (I and II) at the higher noise levels (65 and 75 dB[A]). NH participants significantly benefited from the application of Roger in noise for higher levels, too. In both groups, no significant difference was detected between any of the different listening conditions at 55 dB(A) competing noise. There was also no significant difference between any of the Roger conditions III, IV, and V across all noise levels.The application of the advanced remote wireless microphone system, Roger, in SSD CI recipients provided significant benefits in speech recognition for distant speakers at higher noise levels. In NH participants, the application of Roger also produced a significant benefit in speech recognition in noise.

Objective. The objective of this study was to evaluate the level of adaptation of patients to newly fitted complete dentures in their dominant and nondominant sides, by means of ElectromyoFigureic signals. Materials and Methods. Eighty-eight patients with complete dentures were evaluated in the study. Masticatory muscle (masseter and temporal) bioelectric activity of the patients with complete dentures was recorded at maximum intercuspal relation. Parametric statistical data were analyzed with one-way repeated measures ANOVA test. Results. Measurement time was significantly different for both dominant (DS) and nondominant (NDS) sides: FΣs-DS = 21.51, p=0.0001; FΣs-NDS = 13.25, p=0.0001. Gender was also significantly different: FΣs-DS-gender = 41.53, p=0.001; FΣs-NDS-gender = 85.76, p=0.0001. The average surface area values showed significant difference in females. Prior experience with dentures showed no significant difference for both sides of mastication: FΣs-DS-experiences = 1.83, p=0.1772; F Σs-NDS-experiences = 3.30, p=0.0697. Conclusion. The planimetric indicators of bioelectric activity of masseter and temporalis muscles at maximum physiological loading conditions are significant discriminators of the level of functional adaptation of patients with new complete dentures.

The purpose of the project was to evaluate an underwater weighing (UWW) and residual lung volume (RV) familiarization program developed for adults with Prader-Willi syndrome (PWS). UWW was conducted on 15 adults (10 men, 5 women) with PWS following a UWW familiarization program. Repeated measures ANOVA revealed no difference in percent body fat derived from UWW over the four sessions, F(3, 27) = 0.80, p = .505, with an intraclass reliability coefficient of R = .93. There was, however, a significant difference in RV, F(3, 27) = 5.25, p = .006, with an intraclass reliability coefficient of R = .65. The familiarization program is recommended for implementation prior to measuring percent body fat via UWW. However, predicting the RV may be an easier and more consistent alternative to measuring the RV in adults with PWS.
