This paper explores the relationships among attitudes toward mathematics, teaching, and academic achievement in mathematics. Based on the contextual and social nature of academic self-concept, two complementary studies are discussed. The first study from the northeastern United States examined the relationships among these variables in 84 high school students. A second study from southwestern Nigeria examined how teaching approach can engender changes in student achievement and attitudes toward mathematics through the analysis of 36 preservice teachers associated with 830 students. Instruments used included the Program for International Student Assessment, the June 2012 New York State Integrated Algebra Regents Examination, the Student Mathematics Attitudes Questionnaire, and the Student Mathematics Achievement Test. Analytic methods included descriptive statistics, correlations, linear regression, and analysis of covariance. Together, the research supports the link between attitudes toward mathematics and academic achievement and suggests that teachers can improve student attitudes toward mathematics based on their teaching approach.

Purpose: This systematic review aims to elucidate a non-operative rehabilitation program that optimizes recovery based on published approaches and outcomes. Methods: Searches of four databases from inception to 1 January 2020 were performed to identify clinical studies addressing the non-operative management of simple elbow dislocations. Results: Of 2435 studies that were eligible for title screen, 15 studies satisfied inclusion criteria. Three randomized control studies demonstrated that early mobilization expedited the return of range of motion, function and return to work or activities, however, resulted in increased pain within the six-week rehabilitation period compared to Plaster of Paris casting for 21 days. Patients returned to work sooner after early mobilization (10 vs. 18 days; p = 0.02) compared to Plaster of Paris casting. In all studies, early mobilization resulted in similar re-dislocation rates of 1.3% (3/237) versus 2.2% (12/549) in those with Plaster of Paris casting as well as lower incidence of heterotopic ossification (36% vs. 54%). No significant differences between rehabilitation protocols were determined; however, the large majority of recent papers utilized rehabilitation protocols. Conclusion: Early mobilization of simple elbow dislocations results in early return of Range-of-Motion, function and return to work with no increase in complication rates; however, increased pain during the rehabilitation period.

The high physiologic demands of sports create dynamic stress on joints, soft tissues, and nerves which may lead to injuries in the athlete. Electrodiagnostic (EDx) assessment is essential to identify the correct diagnosis, localization, and prognosis, to guide management of sports‐related neuropathies. A comprehensive review was performed to provide the EDx medical consultant with a practical approach to the common peripheral nerve disorders seen in athletes. Sports‐related neuropathies reviewed include transient traumatic irritation of the brachial plexus and/or cervical nerve roots (“Burners and stingers,”) suprascapular and axillary neuropathies, ulnar neuropathy at the elbow (UNE) in throwers, ulnar neuropathy at the hand/wrist in cyclists, multi‐ligamentous knee injury, and foot/ankle neuropathies including tarsal tunnel syndrome. A thorough understanding of peripheral anatomy, possible entrapment sites, mechanisms of injury, and key physical examination findings is essential for correct diagnosis. EDx assessments beyond routine studies are generally required for sports‐related neuropathy, which may not necessarily follow typical entrapment patterns. Adjunct diagnostic imaging, such as point‐of‐care ultrasound and magnetic resonance imaging, are helpful tools to identify associated musculoskeletal pathology such as compressive cysts or nerve entrapment, which may be amenable to interventional or surgical treatment. When no clear reversible structural pathology exists, management of sports‐related neuropathy is athlete‐specific and generally multi‐modal, involving a combination of physical rehabilitation techniques to address muscle imbalances, load management, protective equipment, and interventional pain procedures.

Objective: Acute metatarsal fractures are a common lower extremity injury. Although surgery may be recommended in specific cases, most are treated nonoperatively. Treatment protocols vary significantly among practitioners, with no consensus on the most efficacious approach. This systematic review aims to identify the effect of treatment protocols on union rate and functional outcome after an acute fifth metatarsal tuberosity fracture. Literature Survey: Multiple databases, including CINAHL, EMBASE, MEDLINE, and the Cochrane CEntral Register of Controlled Trials (CENTRAL) were searched from database inception to March 4, 2018 to identify clinical studies addressing nonoperative management of metatarsal fractures reporting nonunion, pain, and/or length of recovery. Methodology: Two reviewers independently completed title, abstract, and full‐text screening. Data abstraction was completed in duplicate. Outcome measures and complications were descriptively analyzed. Synthesis: A total of 1941 studies were eligible for screening. Seven studies (four randomized controlled trials and three prospective cohort studies) satisfied inclusion criteria. This resulted in a total of 388 patient with acute fifth metatarsal tuberosity fractures in 12 different treatment arms, with the most common treatment including plaster casting (7). The mean age was 42 years (27 to 56 years), and the overall nonunion rate was low (1.1%). Four unique functional scores were reported across all studies, and all showed good to excellent short‐term results. The overall qualities of studies were moderate, with particular limitations in randomization and concealment allocation. Conclusion: Most acute fifth metatarsal tuberosity fractures heal well, with good‐to‐excellent functional outcomes with nonoperative treatment, regardless of technique. We recommend a conservative rehabilitation framework, including 2 to 3 weeks of immobilization in a walking cast, followed by gradual increase in activity and strengthening until clinical union is achieved.

Objective: To systematically review and evaluate the efficacy and complication profile of prolotherapy using hyperosmolar dextrose solution injection for rotator cuff tendinopathy.Literature Survey: MEDLINE, EMBASE, CINAHL, and the Cochrane Central Register of Controlled Trials (from inception to 1 July, 2019).Methodology: A comprehensive search was completed to identify randomized controlled trials addressing prolotherapy using hyperosmolar dextrose solution for rotator cuff tendinopathy. Two reviewers independently screened the titles, abstracts, and full texts, and then extracted data from eligible studies. All reported outcome measures and complications were analyzed descriptively.Synthesis: Five studies satisfied inclusion criteria. Included studies analyzed a total of 272 participants with a final follow-up ranging from 6 weeks to 12 months. Prolotherapy differed greatly among studies. Two studies used a multisite enthesis injection protocol while the other three used ultrasound-guided protocols. Two of the studies used an intrasubstance supraspinatus injection and three used a supraspinatus enthesis injection. Control groups consisted of nonoperative rehabilitation including physical therapy and medical management in three studies, supraspinatus saline enthesis injection in one study, and corticosteroid injection in one study. There was statistically significant improvement in pain intensity with multisite injection protocols compared to physical therapy and medical management in both studies. Ultrasound-guided supraspinatus injection trials did not find any statistically significant difference in pain intensity, range of motion, strength, function, or ultrasound characteristics compared to controls of enthesis saline injection or corticosteroid. The complication rate was low, with only 6/272 participants experiencing adverse events consisting of transient increase in pain for 1 to 2 days postintervention.Conclusions: Prolotherapy with hyperosmolar dextrose solution is a potentially effective adjuvant intervention to physical therapy for patients with rotator cuff tendinopathy ranging from tendinosis to partial-thickness and small full-thickness tears. Further studies are necessary to determine effects in subpopulations as well as optimal technique including dextrose concentration, volume, and location. [ABSTRACT FROM AUTHOR]
