Understanding the burden of chronic back pain: a spatial microsimulation of chronic back pain at small area level across England.

PURPOSE: Chronic back pain (CBP) carries a significant burden. Understanding how and why CBP prevalence varies spatially, as well as the potential impact of policies to decrease CBP would prove valuable for public health planning. This study aims to simulate and map the prevalence of CBP at ward-level across England, identify associations which may explain spatial variation, and explore 'what-if' scenarios for the impact of policies to increase physical activity (PA) on CBP. METHODS: A two-stage static spatial microsimulation approach was used to simulate CBP prevalence in England, combining national-level CBP and PA data from the Health Survey for England with spatially disaggregated demographic data from the 2011 Census. The output was validated, mapped, and spatially analysed using geographically weighted regression. 'What-if' analysis assumed changes to individuals' moderate-to-vigorous physical activity (MVPA) levels. RESULTS: Large significant clusters of high CBP prevalence were found predominantly in coastal areas and low prevalence in cities. Univariate analysis found a strong positive correlation between physical inactivity and CBP prevalence at ward-level (R2 = 0.735; Coefficient = 0.857). The local model showed the relationship to be stronger in/around cities (R2 = 0.815; Coefficient: Mean = 0.833, SD = 0.234, Range = 0.073-2.623). Multivariate modelling showed this relationship was largely explained by confounders (R2 = 0.924; Coefficient: Mean = 0.070, SD = 0.001, Range = 0.069-0.072). 'What-if' analysis showed a detectable reduction in CBP prevalence for increases in MVPA of 30 and 60 min (- 2.71%; 1, 164, 056 cases). CONCLUSION: CBP prevalence varies at ward-level across England. At ward-level, physical inactivity is strongly positively correlated with CBP. This relationship is largely explained by geographic variation in confounders (the proportion of residents that are: over 60, in low-skilled jobs, female, pregnant, obese, smokers, white or black, disabled). Policies to increase PA by 30 min weekly MVPA will likely result in a significant reduction in CBP prevalence. To maximise their impact, policies could be tailored to areas of high prevalence, which are identified by this study.

Assessment of Fatigue and Recovery in Sport: Narrative Review.

Fatigue is a phenomenon associated with decreases in both physical and cognitive performances and increases in injury occurrence. Competitive athletes are required to complete demanding training programs with high workloads to elicit the physiological and musculoskeletal adaptations plus skill acquisition necessary for performance. High workloads, especially sudden rapid increases in training loads, are associated with the occurrence of fatigue. At present, there is limited evidence elucidating the underlying mechanisms associating the fatigue generated by higher workloads and with an increase in injury risk. The multidimensional nature and manifestation of fatigue have led to differing definitions and dichotomies of the term. Consequently, a plethora of physiological, biochemical, psychological and performance markers have been proposed to measure fatigue and recovery. Those include self-reported scales, countermovement jump performance, heart rate variability, and saliva and serum biomarker analyses. The purpose of this review is to provide an overview of fatigue and recovery plus methods of assessments.

Self-Report and Contemporaneously Recorded Running Agreement in Recreational Athletes.

ABSTRACT: Leech RD, Grunseit A, and Edwards KL. Self-report and contemporaneously recorded running agreement in recreational athletes. J Strength Cond Res 36(7): 1922-1929, 2022-Accurate assessment of running exposure in research or clinical practice relies on the ability to measure the behavior validly and reliably. Self-reported physical activity (PA) (including running), although commonly used, is subject to bias. User-owned wearable technological devices provide a potential contemporaneously collected data source for validating retrospective running-specific questionnaires. This study assesses agreement between self-reported running and contemporaneously collected running data. Self-reported running and corresponding contemporaneously recorded for current (at the time of questionnaire completion) and historical (6 months prior) was collected. Concordance Correlations and Bland-Altman Limits of Agreement measured extent of agreement. Categories for Metabolic Equivalent Task (MET) hours per week were calculated from total running distance. Unweighted and weighted Kappas were used to compare classification of levels of running by the 2 data sources. Running data were collected from 139 subjects (mean age 51.1 years). Self-report data were higher than contemporaneous data. Average estimated pace from both sources were similar, with high variance in some individuals. Differences of 43.5-57.1% were reported for current mean weekly running distances for 7-day, 4-week, and 12-week running periods. The level of agreement in classification between self-report and contemporaneous running data MET/HR categories was fair (unweighted K = 0.24-0.33) to moderate (weighted K = 0.46-0.63). Compared with contemporaneous running data, runners over-estimate the frequency, distance, and duration of running in self-report. Runners tend to discount nonrunning periods and unusual runs when estimating current and historical "average" running. The opportunities and limitations of different contemporaneous running data collection methods as a PA comparator must be acknowledged.

Outcomes of Closed Versus Open Defects After Local Excision of Rectal Neoplasms: A Multi-institutional Matched Analysis.

BACKGROUND: The management of the rectal wall defect after local excision of rectal neoplasms remains controversial, and the existing data are equivocal. OBJECTIVE: This study aimed to determine the effect of open versus closed defects on postoperative outcomes after local excision of rectal neoplasms. DESIGN: Data from 3 institutions were analyzed. Propensity score matching was performed in one-to-one fashion to create a balanced cohort comparing open and closed defects. SETTINGS: This study was conducted at high-volume specialist referral hospitals. PATIENTS: Adult patients undergoing local excision via transanal endoscopic surgery from 2004 to 2016 were included. Patients were assigned to open- and closed-defect groups, and further stratified by full- or partial-thickness excision. INTERVENTION: Closure of the rectal wall defect was performed at the surgeon's discretion. MAIN OUTCOME MEASURES: The primary outcome measured was the incidence of 30-day complications. RESULTS: A total of 991 patients were eligible (593 full-thickness excision with 114 open and 479 closed, and 398 partial-thickness excision with 263 open and 135 closed). After matching, balanced cohorts consisting of 220 patients with full-thickness excision and 210 patients with partial-thickness excision were created. Operative time was similar for open and closed defects for both full-and partial-thickness excision. The incidence of 30-day complications was similar for open and closed defects after full- (15% vs. 12%, p = 0.432) and partial-thickness excision (7% vs 5%, p = 0.552). The total number of complications was also similar after full- or partial-thickness excision. Patients undergoing full-thickness excision with open defects had a higher incidence of clinically significant bleeding complications (9% vs 3%, p = 0.045). LIMITATIONS: Data were obtained from 3 institutions with different equipment and perioperative management over a long time period. CONCLUSIONS: There was no difference in overall complications between open and closed defects for patients undergoing local excision of rectal neoplasms, but there may be more bleeding complications in open defects after full-thickness excision. A selective approach to defect closure may be appropriate. See Video Abstract at http://links.lww.com/DCR/A470.

A validation of the Nottingham Clavicle Score: a clavicle, acromioclavicular joint and sternoclavicular joint-specific patient-reported outcome measure.

BACKGROUND: Patients with acromioclavicular joint (ACJ) and sternoclavicular joint (SCJ) injuries and with clavicle fractures are typically younger and more active than those with other shoulder pathologies. We developed the Nottingham Clavicle Score (NCS) specifically for this group of patients to improve sensitivity for assessing the outcomes of treatment of these conditions compared with the more commonly used Constant Score (CS) and Oxford Shoulder Score (OSS). MATERIALS AND METHODS: This was a cohort study in which the preoperative and 6-month postoperative NCS evaluations of outcome in 90 patients were compared with the CS, OSS, Imatani Score (IS), and the EQ-5D scores. Reliability was assessed using the Cronbach α. Reproducibility of the NCS was assessed using the test/retest method. Effect sizes were calculated for each score to assess sensitivity to change. Validity was examined by correlations between the NCS and the CS, OSS, IS, and EQ-5D scores obtained preoperatively and postoperatively. RESULTS: Significant correlations were demonstrated preoperatively with the OSS (P = .025) and all subcategories of the EQ-5D (P < .05) and postoperatively with the OSS (P < .001), CS (P = .008), IS (P < .001), and all subcategories of EQ-5D (P < .02). The NCS had the largest effect size (1.92) of the compared scores. Internal consistency was excellent (Cronbach α = 0.87). CONCLUSION: The NCS has been proven to be a valid, reliable and sensitive outcome measure that accurately measures the level of function and disability in the ACJ, SCJ and clavicle after traumatic injury and in degenerative disease.

Does arthroscopic sub-acromial decompression really work for sub-acromial impingement syndrome: a cohort study.

BACKGROUND: Health Economists in Denmark have reported poor outcomes and low and delayed return to work for patients treated for Sub-Acromial Impingement syndrome (SAIS) by Arthroscopic Sub-Acromial Decompression (ASAD). In this setting it is important to evaluate outcomes following this commonly performed operation to justify undertaking it on our patients. The purpose of the study was to evaluate the effectiveness of ASAD for patients with SAIS and correlate clinical outcome with rate of return to work. METHODS: Prospective cohort study and retrospective review of data from the Nottingham Shoulder database. Inclusion criteria: Patients diagnosed clinically with SAIS by an experienced shoulder surgeon, who have failed conservative treatment (physiotherapy and sub-acromial injection), undergoing ASAD. Pre-operative and 6-month post-operative Oxford Shoulder Score (OSS) and Constant Score (CS) were compared. The rates of return to pre-operative work and hobbies were also analysed. Statistical analysis was carried out using the Wilcoxon signed rank test. RESULTS: 73 patients with OSS (51 also with CS documentation) were included. The improvement in median OSS between pre-operative (24) and 6-month follow-up (39) was +15 (Z = -6.726, p < 0.0001, T = 6, r = 0.55). The difference in median CS between pre-operative (39) and 6-month follow-up (67) was +28 (Z = -5.435, p < 0.0001,T = 6, r = 0.59). Improvement in median pain score was +5 (7,12, p < 0.0001) median ADL was +5.5 (10.5,16, p < 0.0001) median ROM was +13 (18,31, p < 0.0001) and median strength was +4 (3,7, p < 0.0001). 76% returned to their pre-operative level of work (mean time = 11.5 weeks post surgery). 79% returned to pre-operative hobbies at a mean of 11.8 weeks after surgery. CONCLUSION: There is a significant improvement in both subjective and objective outcome 6 months after ASAD in patients with SAIS who have had previous failed conservative treatment. The rate of return to work was good for these patients in contrast to that reported for Danish patients. ASAD is a successful method of treatment for patients with SAIS who have had an initial trial of failed conservative treatment.

Chronic back pain prevalence at small area level in England - the design and validation of a 2-stage static spatial microsimulation model.

Spatially disaggregated estimates provide valuable insights into the nature of a disease. They highlight inequalities, aid public health planning and identify avenues for further research. Spatial microsimulation is advantageous in that it can be used to create large microdata sets with intact microlevel relationships between variables, which allows analysis of relationships between variables locally. This methodological paper outlines the design and validation of a 2-stage static spatial microsimulation model for chronic back pain prevalence across England, suitable for policy modelling. Data used was obtained from the Health Survey for England and the 2011 Census. Microsimulation was performed using SimObesity, a previously validated static deterministic program, and the synthetic chronic back pain microdataset was internally validated. The paper also highlights modelling considerations for researchers embarking on similar work, as well as future directions for research in this area of microsimulation.

The effectiveness of cupping therapy on low back pain: A systematic review and meta-analysis of randomized control trials.

OBJECTIVES: This study aims to investigate the effectiveness of cupping therapy on low back pain (LBP). METHODS: Medline, Embase, Scopus and WANFANG databases were searched for relevant cupping RCTs on low back pain articles up to 2023. A complementary search was manually made on 27 September for update screening. Full-text English and Chinese articles on all ethnic adults with LBP of cupping management were included in this study. Studies looking at acute low back pain only were excluded. Two independent reviewers screened and extracted data, with any disagreement resolved through consensus by a third reviewer. The methodological quality of the included studies was evaluated independently by two reviewers using an adapted tool. Change-from-baseline outcomes were treated as continuous variables and calculated according to the Cochrane Handbook. Data were extracted and pooled into the meta-analysis by Review Manager software (version 5.4, Nordic Cochrane Centre). RESULTS: Eleven trials involving 921 participants were included. Five studies were assessed as being at low risk of bias, and six studies were of acceptable quality. High-quality evidence demonstrated cupping significantly improves pain at 2-8 weeks endpoint intervention (d=1.09, 95% CI: [0.35-1.83], p = 0.004). There was no continuous pain improvement observed at one month (d=0.11, 95% CI: [-1.02-1.23], p = 0.85) and 3-6 months (d=0.39, 95% CI: [-0.09-0.87], p = 0.11). Dry cupping did not improve pain (d=1.06, 95% CI: [-0.34, 2.45], p = 0.14) compared with wet cupping (d=1.5, 95% CI: [0.39-2.6], p = 0.008) at the endpoint intervention. There was no evidence indicating the association between pain reduction and different types of cupping (p = 0.2). Moderate- to low-quality evidence showed that cupping did not reduce chronic low back pain (d=0.74, 95% CI: [-0.67-2.15], p = 0.30) and non-specific chronic low back pain (d=0.27, 95% CI: [-1.69-2.24], p = 0.78) at the endpoint intervention. Cupping on acupoints showed a significant improvement in pain (d=1.29, 95% CI: [0.63-1.94], p < 0.01) compared with the lower back area (d=0.35, 95% CI: [-0.29-0.99], p = 0.29). A potential association between pain reduction and different cupping locations (p = 0.05) was found. Meta-analysis showed a significant effect on pain improvement compared to medication therapy (n = 8; d=1.8 [95% CI: 1.22 - 2.39], p < 0.001) and usual care (n = 5; d=1.07 [95% CI: 0.21- 1.93], p = 0.01). Two studies demonstrated that cupping significantly mediated sensory and emotional pain immediately, after 24 h, and 2 weeks post-intervention (d= 5.49, 95% CI [4.13-6.84], p < 0.001). Moderate evidence suggested that cupping improved disability at the 1-6 months follow-up (d=0.67, 95% CI: [0.06-1.28], p = 0.03). There was no immediate effect observed at the 2-8 weeks endpoint (d=0.40, 95% CI: [-0.51-1.30], p = 0.39). A high degree of heterogeneity was noted in the subgroup analysis (I2 >50%). CONCLUSION: High- to moderate-quality evidence indicates that cupping significantly improves pain and disability. The effectiveness of cupping for LBP varies based on treatment durations, cupping types, treatment locations, and LBP classifications. Cupping demonstrated a superior and sustained effect on pain reduction compared with medication and usual care. The notable heterogeneity among studies raises concerns about the certainty of these findings. Further research should be designed with a standardized cupping manipulation that specifies treatment sessions, frequency, cupping types, and treatment locations. The actual therapeutic effects of cupping could be confirmed by using objective pain assessments. Studies with at least six- to twelve-month follow-ups are needed to investigate the long-term efficacy of cupping in managing LBP. TRIAL REGISTRATION: This systematic review was initially registered on PROSPERO with registration code: CRD42021271245 on 08 September 2021.

Childhood consumption of fruit and vegetables across England: a study of 2306 6-7-year-olds in 2007.

The School Fruit and Vegetable Scheme (SFVS) provides children in government-run schools in England with a free piece of fruit or a vegetable each school day for the first 3 years of school. The present study examines the impact of the SFVS, in terms of its contribution towards the total daily intake of fruit and vegetables by children across England. Quantitative dietary data were collected from 2306 children in their third year of school, from 128 schools, using a 24 h food diary. The data were examined at different spatial scales, and variations in the impact of the scheme across areas with different socio-economic characteristics were analysed using a deprivation index and a geodemographic classification. The uptake of the SFVS and the total intake of fruit and vegetables by children varied across different parts of England. Participation in the SFVS was positively associated with fruit and vegetable consumption. That is, in any one area, those children who participated in the SFVS consumed more fruit and vegetables. However, children living in deprived areas still consumed less fruit and vegetables than children living in more advantaged areas: the mean daily frequency of fruit and vegetables consumed, and rates of consumption of fruit or vegetables five times or more per d, decreased as deprivation increased (r -0.860; P = 0.001; r -0.842; P = 0.002). So the SFVS does not eliminate the socio-economic gradient in fruit and vegetable consumption, but it does help to increase fruit and vegetable consumption in deprived (and affluent) areas.

Management of metastatic sacral tumours.

PURPOSE: Metastatic involvement of the sacrum is rare and there is a paucity of studies which deal with the management of these tumours since most papers refer to primary sacral tumours. This study aims to review the available literature in the management of sacral metastatic tumours as reflected in the current literature. METHODS: A systematic review of the English language literature was undertaken for relevant articles published over the last 11 years (1999-2010). The PubMed electronic database and reference lists of key articles were searched to identify relevant studies using the terms "sacral metastases" and "metastatic sacral tumours". Studies involving primary sacral tumours only were excluded. For the assessment of the level of evidence quality, the CEBM (Oxford Centre of Evidence Based Medicine) grading system was utilised. RESULTS: The initial search revealed 479 articles. After screening, 16 articles identified meeting our inclusion criteria [1 prospective cohort study on radiosurgery (level II); 2 case series (level III); 4 retrospective case series (level IV) and 9 case reports (level IV)]. CONCLUSION: The mainstay of management for sacral metastatic tumours is palliation. Preoperative angioembolisation is shown to be of value in cases of highly vascularised tumours. Radiotherapy is used as the primary treatment in cases of inoperable tumours without spinal instability where pain relief and neurological improvement are attainable. Minimal invasive procedures such as sacroplasties were shown to offer immediate pain relief and improvement with ambulation, whereas more aggressive surgery, involving decompression and sacral reconstruction, is utilised mainly for the treatment of local advanced tumours which compromise the stability of the spine or threaten neurological status. Adjuvant cryosurgery and radiosurgery have demonstrated promising results (if no neurological compromise or instability) with local disease control.

Chronic postoperative pain after total knee arthroplasty: The potential contributions of synovitis, pain sensitization and pain catastrophizing-An explorative study.

BACKGROUND: A subset of osteoarthritis patients will experience chronic postoperative pain after total knee arthroplasty (TKA), but the source of pain is unclear. The aim of this exploratory study was to assess patients with and without postoperative pain after TKA using magnetic resonance imaging (MRI), quantitative sensory testing (QST), clinical assessment of pain and assessments of catastrophizing thoughts. METHODS: Forty-six patients completed the 6-month postoperative assessment. MRI findings were scored according to the MRI Osteoarthritis Knee Score recommendation for Hoffa synovitis, effusion size and bone marrow lesions. QST included assessment of pressure pain thresholds (PPTs), temporal summation of pain (TSP) and conditioned pain modulation (CPM). Pain catastrophizing was assessed using the Pain Catastrophizing Scale (PCS). Clinical pain assessment was conducted using a visual analogue scale (VAS, 0-10 cm), and groups of moderate-to-severe (VAS > 3) and none-to-mild postoperative pain (VAS ≤ 3) were identified. RESULTS: Patients with moderate-to-severe postoperative pain (N = 15) demonstrated higher grades of Hoffa synovitis (p < 0.001) and effusion size (p < 0.001), lower PPTs (p = 0.039), higher TSP (p = 0.001) and lower CPM (p = 0.014) when compared with patients with none-to-mild postoperative pain (N = 31). No significant difference was found in PCS scores between the two groups. Multiple linear regression models found synovitis (p = 0.036), effusion size (p = 0.003), TSP (p = 0.013) and PCS (p < 0.001) as independent parameters contributing to the postoperative pain intensity. CONCLUSION: These exploratory findings could indicate that chronic postoperative pain after TKA is a combination of joint-related synovitis and effusion, sensitization of central pain mechanisms and potentially pain catastrophizing thoughts, but larger studies are needed to confirm this. SIGNIFICANCE: The end-stage treatment of knee osteoarthritis is total knee arthroplasty. Some patients experience chronic postoperative pain after total knee arthroplasty, but the mechanism for chronic postoperative pain is widely unknown. The current study indicates that higher levels postoperative of synovitis and effusion, higher temporal summation of pain and higher pain catastrophizing scores could be associated with higher chronic postoperative pain.

Serial cross-sectional analysis of prevalence of overweight and obese children between 1998 and 2003 in Leeds, UK, using routinely measured data.

OBJECTIVE: To monitor growth trends in young children in order to ascertain success (or otherwise) in halting the rapid rise in childhood obesity prevalence, and to assess the suitability of using routinely measured data for this purpose. DESIGN: Retrospective serial cross-sectional analyses of the proportion of obese children (logistic regression) and BMI standard deviation score (linear regression/maps) were undertaken. BMI coverage was calculated as percentage of sample with data ('usual'), percentage of total births and percentage of census values. BMI was standardised for age and sex (British reference data set). SETTING: Metropolitan Leeds, UK. SUBJECTS: Children aged 3 to 6 years. Weight, height, sex, age and postcode data were collected from Primary Care Trust records. RESULTS: Data were collected on 42 396 children, of whom 13 020 (31 %) were excluded due to missing data/data problems. Seventy-two per cent of 3-year-olds and 92 % of 5-year-olds had data recorded ('usual' coverage). From 1998 to 2003 there was a significant increase in the proportion of obese children (4.5 % to 6.6 %; P < 0.001); children were 1.5 times more likely to be obese in 2003 than in 1998. CONCLUSIONS: Childhood obesity rose significantly between 1998 and 2003. Routinely measured data are an important means of monitoring population-level obesity trends, although more effort is required to reduce the quantity of data-entry errors, for relatively low marginal cost.

Association of Sports Participation With Osteoarthritis: A Systematic Review and Meta-Analysis.

BACKGROUND: The association between participating in sport and osteoarthritis is not fully understood. PURPOSE: To investigate the association between osteoarthritis and participating in sports not listed in previous reviews: American football, archery, baseball, bobsleigh, curling, handball, ice hockey, shooting, skeleton, speed skating, and wrestling. STUDY DESIGN: Systematic review; Level of evidence, 3. METHODS: We searched 4 electronic databases and hand searched recent/in-press editions of relevant journals. The criteria for study selection were case-control studies, cohort studies, nested case-control studies, and randomized trials with a control group that included adults to examine the effect of exposure to any of the included sports on the development of osteoarthritis. RESULTS: The search returned 6197 articles after deduplication. Nine studies were included in the final review, covering hip, knee, and ankle osteoarthritis. There were no studies covering archery, baseball, skeleton, speed skating, or curling. The 6 sports included in the review were analyzed as a collective; the results of the meta-analysis indicated that participation in the sports analyzed was associated with an increased risk of developing osteoarthritis of the hip (relative risk [RR] = 1.67 [95% confidence interval (CI), 1.15-2.41]; P = .04), knee (RR = 1.60 [95% CI, 1.23-2.08]; P < .001), and ankle (RR = 7.08 [95% CI, 1.24-40.51]; P = .03) as compared with controls. Meta-analysis suggested a significantly increased likelihood of developing hip osteoarthritis through participating in wrestling (RR = 1.78 [95% CI, 1.20-2.64]; P = .004) and ice hockey (RR = 1.70 [95% CI, 1.27-2.29]; P < .001), while there was no significant difference through participating in handball (RR = 2.50 [95% CI, 0.85-7.36]; P = .10). Likelihood of developing knee osteoarthritis was significantly increased in wrestling (RR = 2.22 [95% CI, 1.59-3.11]) and ice hockey (RR = 1.52 [95% CI, 1.18-1.96]; both P < .002). According to the meta-analysis, shooting did not have a significant effect on the RR of knee osteoarthritis as compared with other sports (RR = 0.43 [95% CI, 0.06-2.99]; P = .39). CONCLUSION: The likelihood of developing hip and knee osteoarthritis was increased for ice hockey and wrestling athletes, and the risk of developing hip osteoarthritis was increased for handball athletes. The study also found that participation in the sports examined, as a collective, resulted in an increased risk of developing hip, knee, and ankle osteoarthritis.

Instructor facilitation mediates students' negative perceptions of active learning instruction.

Studies have demonstrated students' resistance to active learning, despite evidence illustrating that their learning is improved relative to students in lectures. Specifically, while active learning and group work are effective at engaging students in their learning process, studies report that students' perceptions of active learning approaches are not always positive. What remains underexplored is whether students' perceptions of active learning improve with effective instructor facilitation and whether there exists differential perceptions between racially minoritized students and represented students. Here, we estimate students' perceptions of effective instructor facilitation as the mediator in the relationship between active learning and perceptions of learning and perceived utility for class activities (task value). Then, we examine differences by racial identification. We collected classroom observation data to empirically categorize courses as active learning or lecture-based and surveyed 4,257 college students across 25 STEM classrooms at a research-intensive university. We first examined the relationship between active learning on student perceptions and found a negative relationship between active learning and perceptions of learning and task value for both racially minoritized students and represented students. Next, we assessed whether students' perceptions of instructor effectiveness in facilitating group activities mediate these negative relationships. We found that, on average, students of all races were more likely to positively perceive instructor facilitation in active learning classes relative to lectures. In turn, the positive perceptions of instructor facilitation partially suppressed the negative relationship between active learning and perceptions of learning and task value. These results demonstrate that effective instructor facilitation can influence both students' self-assessment of learning and perceived utility of the learning activities, and underscores the importance of developing pedagogical competence among college instructors.

Integrating sport and exercise medicine clinics into the National Health Service: a qualitative study.

OBJECTIVES: To explore the services National Health Service (NHS)-based sport and exercise medicine (SEM) clinics can offer, and the barriers to creating and integrating SEM services into the NHS. METHODS: Semi-structured interviews were undertaken to collect data from identified 'stakeholders'. Stakeholders were identified as individuals who had experience and knowledge of the speciality of SEM and the NHS. An inductive thematic analysis approach was taken to analyse the data. RESULTS: N=15 stakeholder interviews. The management of musculoskeletal (MSK) injuries (both acute and chronic) and concussion were highlighted as the two key services that SEM clinics can offer that would most benefit the NHS. MSK ultrasound was also mentioned by all stakeholders as a critical service that SEM clinics should provide. While exercise medicine is an integral part of SEM, SEM clinics should perhaps not have a heavy exercise medicine focus. The key barriers to setting up SEM clinics were stated to be convincing NHS management, conflict with other specialities and a lack of awareness of the speciality. CONCLUSION: The management of acute MSK injuries and concussion should be the cornerstone of SEM services, ideally with the ability to provide MSK ultrasound. Education of others on the speciality of SEM, confirming consistent 'unique selling points' of SEM clinics and promoting how SEM can add value to the NHS is vital. If the successful integration of SEM into the NHS is not widely achieved, we risk the NHS not receiving all the benefits that SEM can provide to the healthcare system.
