Learning anatomy by virtual reality and augmented reality. A scope review.

During the last century, there were no significant changes in the teaching methods of anatomy in universities, predominating expositive lectures, and anatomy laboratory activities. With the advent of new technologies, simulators, augmented reality, and virtual reality, new teaching possibilities have emerged that may provide assistance and, in some situations, replace traditional methods of teaching. In this narrative scope review we evaluate articles that compare traditional methods with virtual reality or augmented reality through a search on Cochrane library, MEDLINE, EMBASE, and LILACS databases, using the MeSH terms "Anatomy", "Virtual Reality", "Augmented Reality", "Video Games", "Education Medical, Undergraduate", "Teaching" and "Simulation Training". We concluded that virtual reality and augmented reality have a promising value for teaching anatomy in addition to a positive economic impact on universities.

Cardiovascular training vs. resistance training for improving quality of life and physical function in patients with systemic lupus erythematosus: a randomized controlled trial.

OBJECTIVES: To compare the efficacy of cardiovascular training (CT) with resistance training (RT) in improving the health-related quality of life (HRQoL) and physical function of patients with systemic lupus erythematosus (SLE). METHOD: A randomized controlled trial was conducted with participants randomly allocated to either a CT (n = 21), RT (n = 21), or control group (n = 21). The outcomes assessed were: HRQoL using the Medical Outcomes Study 36-Item Short Form Health Survey (SF-36), severity of depression using the Beck Depression Inventory (BDI), disease activity using the SLE Disease Activity Index (SLEDAI), and aerobic capacity using a 12-minute walk test (T12). RESULTS: Sixty-three patients (61 women and two men), aged 42.9 ± 14.4 years, with a mean body mass index (BMI) of 28.7 ± 10.6 kg/m(2), disease duration of 3.8 ± 3.3 years, and not physically active participated in the study. HRQoL improved for both exercise groups but was superior in the RT group. There was no significant difference in physical function between the intervention groups, except for aerobic capacity. Neither training programme was associated with a change in disease activity. CONCLUSIONS: Exercise intervention proved to be better than not exercising. CT was better than RT in improving HRQoL.

Progressive load training for the quadriceps muscle associated with proprioception exercises for the prevention of falls in postmenopausal women with osteoporosis: a randomized controlled trial.

UNLABELLED: This study aims to evaluate the effect of 18-week progressive muscular strength and proprioception training program on the muscle strength of the quadriceps, in prevention of falls in postmenopausal women with osteoporosis. The incidence of falls in the intervention group was significantly lower than in the control group (incidence rate ratio (IRR) = 0.263, 95% CI 0.10-0.68). INTRODUCTION: This study aims to evaluate the effect of a progressive muscular strength and proprioception training program on the muscle strength of the quadriceps, balance, quality of life, and reduction in the risk of falls in postmenopausal women with osteoporosis. METHODS: One hundred sedentary postmenopausal women with osteoporosis, ages ranging from 55 to 75, were selected and randomized into two groups: the intervention group comprised of 50 patients who underwent a 18-week of progressive load training for the quadriceps muscle (50% up to 80% of 1-RM-one maximum repetition) and proprioception training associated to a drug treatment of osteoporosis and the control group that included 50 patients who only underwent a drug treatment of osteoporosis. The muscular strength, balance, functional mobility, and quality of life were evaluated in the beginning and end of the research. The number of falls was evaluated 24 weeks post-treatment. RESULTS: Eighty-five patients concluded the research. The program promoted a significant difference among the groups for SF-36 in the eight sub-scales (p

Interventions for treating posterior cruciate ligament injuries of the knee in adults.

BACKGROUND: Injuries of the posterior cruciate ligament (PCL) of the knee frequently occur in automobile accidents and sports injuries, although they are less frequent overall than injuries of the anterior cruciate ligament (ACL). Some patients show significant symptoms and subsequent articular deterioration, while others are essentially asymptomatic, maintaining habitual function. Management of PCL injuries remains controversial and prognosis can vary widely. Interventions extend from non-operative (conservative) procedures to reconstruction of the PCL, in the hope that the surgical procedure may have a positive effect in the reduction/prevention of future osteoarthritic changes in the knee. OBJECTIVES: To determine the effectiveness and safety of surgical and conservative interventions for PCL injuries in adults. SEARCH STRATEGY: We searched the Cochrane Musculoskeletal Injuries Group Specialised Register (April 2004), the Cochrane Central Register of Controlled Trials (The Cochrane Library Issue 1, 2004), MEDLINE via PubMed (1966 to April 2004), EMBASE (1966 to April 2004), CINAHL (1982 to April 2004), LILACS (1982 to April 2004), SportsDiscus (1975 to April 2004), and reference lists of articles. SELECTION CRITERIA: Randomized or quasi-randomized clinical trials comparing various methods of operative and conservative interventions, and comparisons with each other for the treatment of PCL injuries. DATA COLLECTION AND ANALYSIS: References found with the search strategy were evaluated independently by two review authors. MAIN RESULTS: No randomized or quasi-randomized controlled studies meeting the selection criteria were identified. AUTHORS' CONCLUSIONS: Future research should include randomized controlled trials of acute isolated PCL injuries, or PCL injuries when combined with other ligament injuries of the knee, treated operatively and conservatively. Adequate numbers of patients and an objective methodology for patient evaluation must be used in future studies of these interventions to determine the long-term results.

Interventions for tears of the rotator cuff in adults.

BACKGROUND: Tears of the rotator cuff tendons, which surround the joints of the shoulder, are one of the most common causes of pain and disability in the upper extremity. OBJECTIVES: To review the efficacy and safety of common interventions for tears of the rotator cuff in adults. SEARCH STRATEGY: We searched the Cochrane Musculoskeletal Injuries Group specialised trail register (July 2002), the Cochrane Controlled Trials Register (The Cochrane Library issue 2, 2002), MEDLINE (1966 to December 2001), EMBASE (1974 to December 2001), Biological Abstracts (1980 to December 2001), LILACS (1982 to December 2001), CINAHL (November 1982 to December 2001), Science Citation Index and reference lists of articles. We also contacted authors and handsearched conference proceedings focusing on shoulder conditions. SELECTION CRITERIA: Randomised or quasi-randomised clinical trials involving tears of the rotator cuff were the focus of this review. All trials involving conservative interventions or surgery were included (non-steroidal anti-inflammatory drugs, intra-articular or subacromial glucocorticosteroid injection, oral glucocorticosteroid treatment, physiotherapy, and open or arthroscopic surgery). DATA COLLECTION AND ANALYSIS: Two reviewers independently assessed suitability for inclusion, methodological quality and extracted data. Dichotomous data were presented as relative risks (RR) and 95% confidence intervals (CI), using the fixed effects model. MAIN RESULTS: Eight trials involving 455 people were included and 393 patients analysed. Trials were grouped in eight categories of conservative or surgical treatment. The median quality score of all trials combined was 16 out of a possible 24 points, with a range of 12-18. In general, included trials differed on diagnostic criteria for rotator cuff tear, there was no uniformity in reported outcome measures, and data which could be summarised were rarely reported. Only results from two studies comparing open repair to arthroscopic debridement could be pooled. There is weak evidence for the superiority of open repair of rotator cuff tears compared with arthroscopic debridement. REVIEWER'S CONCLUSIONS: There is little evidence to support or refute the efficacy of common interventions for tears of rotator cuff in adults. As well as the need for further well designed clinical trials, uniform methods of defining interventions for rotator cuff tears and validated outcome measures are also essential.
