Abstract
Muscle tendon unit fibre mechanics of hamstring and adductor strain injuries are not well studied, with factors such as fatigue promoted as risk factors in the absence of mechanistic evidence. In this study, musculoskeletal modelling was used to estimate fibre mechanics of four hamstring (biceps femoris long head, biceps femoris short head, semimembranosus and semitendinosus) and four adductor (adductor brevis, adductor longus, adductor magnus and gracilis) muscles during an anticipated cut task. The cut task was performed by 10 healthy elite male U20 basketball players both before and immediately after they played in one (of four) competitive basketball game. Biceps femoris long head produced significantly lower (p = 0.032) submaximal force post-game in the latter part of swing (30.7% to 35.0% of stride), though its peak force occurred later (37%) and remained unchanged. Semimembranosus produced significantly lower (p = 0.006) force post-game (32.9% to 44.9% of stride), which encompassed the instance of peak force (39%). Neither fibre velocity nor fibre length of the investigated muscles were significantly affected by game-play. These finding suggest that if fatigue is a factor in hamstring and adductor muscle strain injuries and is brought about by game-play, it is unlikely through the fibre mechanisms investigated in this study.

Abstract
Background Shoulder pain related to the long head of the biceps tendon (LHBT) tendinopathy can be debilitating and difficult to treat especially in athletes who often elect for surgical intervention. Conservative management is recommended but there are limited established guidelines on the physical therapy (PT) management of the condition. Hypothesis/Purpose The purpose of this study was to establish consensus on conservative, non-surgical physical therapy interventions for individuals with LHBT tendinopathy using the Delphi method approach. Study Design Delphi Study. Methods Through an iterative process, experts in the PT field rated their agreement with a list of proposed treatment interventions and suggested additional interventions during each round. Agreement was measured using a four-point Likert scale. Descriptive statistics including median and percentage agreement were used to measure agreement. Data analysis at the end of Round III produced, by consensus, a list of PT interventions recommended for the management of individuals with LHBT tendinopathy. Consensus was defined as an a priori cutoff of ≥75% agreement. Results The respondent group included 29 international experts in the PT management of individuals with shoulder pain. At the conclusion of the study 61 interventions were designated as recommended based on consensus amongst experts and 9 interventions were not recommended based on the same criteria, 15 interventions did not achieve consensus. Conclusion There is a lack of well-defined, PT interventions used to treat LHBT tendinopathy. Expert respondents reached consensus on multimodal interventions including exercise, manual therapy and patient education to manage LHBT tendinopathy. Level of Evidence 5.

Abstract
[Purpose] Examination and treatment of the long head of the biceps tendon (LHBT)
requires accurate palpation. The purpose of this study was to determine physical
therapists’ reliability and ability to accurately palpate the LHBT in two arm positions
with ultrasound as the gold standard. [Participants and Methods] Examiners palpated the
LHBT within the intertubercular groove (ITG) of the humerus on the bilateral shoulders of
32 asymptomatic (21 female; 24.3 ± 1.9 years) participants in 2 arm positions. The
magnitude of distance between a marker and the border of the ITG was compared between 2
positions using an independent t-test. Percent accuracy was calculated. [Results]
Inter-rater reliability was poor (position 1, k=1.04; position 2,
k=0.016). Overall accuracy rate was 45.7% (117/256). Accuracy was 49.2%
(63/128) and 42.2% (54/128) for testing position 1 and position 2 respectively. Mean
distance palpated from the groove was M=2.58 mm (± 6.2 mm) for position 1
and M=3.77 mm (± 6.6 mm) for position 2. Inaccurate palpation occurred
medially 72.3% (47/65) and 93.2% (69/74) in position 1 and position 2 respectively.
[Conclusion] Results of this study did not support one arm position being more accurate
over another for LHBT palpation.

Abstract
OBJECTIVES To estimate the proportion of physical therapists currently performing dry needling and report current practices patterns. Secondary aims were to report the numbers of minor and major adverse events and determine if these adverse events were related to therapist characteristics. METHODS An anonymous electronic survey was distributed through special interest groups within the United States to physical therapists. Participant demographics and responses were analyzed using descriptive statistics. Associations between variables were examined using chi-square. RESULTS The estimated response rate was 14.4% (n = 865, mean age 39.89, SD 11.73 years). More than half (55.0%, n = 461) of respondents perform dry needling; levels of training varied. Most (78.8%, n = 337) performed 0-3 needling sessions per day, usually lasting < 15 min (67.3% of respondents, n = 288). Therapists commonly performed 3-6 sessions over a patient's course of care (82.0% of respondents, n = 350). Minor adverse events were common; respondents estimated this occurred in 39.6% (SD 31.5) of treatments. Major adverse events were rare, typically not requiring emergency care. Being male (X2 = 8.197, P = 0.004), experienced (>4 years; X2 = 34.635, P < 0.001), and having more training (>61 h; X2 = 8.503, P = 0.004) were associated with reporting a major adverse event occurred during their career. CONCLUSIONS Half of physical therapists surveyed performed dry needling. Practice patterns were consistent with expert opinion. The number of adverse events reported suggests further research is needed to quantify the risks of dry needling. Participant characteristics associated with a major adverse event appear to be related to the number of exposures.

Abstract
Background: Clinically, a discrepancy of fibular position in relation to the tibia has been proposed as a factor in the persistence of chronic ankle instability (CAI). Previous studies have produced conflicting findings, perhaps due to varying radiological methods and measurement of participants in non-weight-bearing positions.Objectives: To compare normalized-fibular position in weight-bearing in individuals with CAI with healthy controls.Design: A weight-bearing lateral X-ray was taken of the affected ankle of 33 adults with CAI and 33 matched controls. The distance between the anterior edges of the distal fibula and tibia was recorded, and then normalized as a proportion of maximal tibial width. Normalized-fibular position was compared between groups using independent t-tests. Intra-class correlation coefficients (ICC2,1) were calculated to determine reliability of measurements. A receiver-operating characteristic (ROC) curve was used to determine sensitivity, specificity, and a cutoff score to differentiate individuals with CAI from controls using normalized-fibular position.Results: Normalized fibular position was significantly different (CAI, 29.7 (6.6)%; healthy, 26.7 (4.8)%) between the groups. Measurement of intra-rater (0.99, 95%CI = 0.98 to 1.00) and inter-rater (0.98, 95%CI = 0.96 to 0.99) reliability were both excellent. The threshold normalized-fibular position was 27%, with a score more than 27% indicating a greater chance of being in the CAI group. Sensitivity was 69.7% and specificity was 54.5% for this threshold.Conclusion: A slightly anteriorly positioned fibula in relation to the tibia was observed in people with CAI. Specificity/sensitivity scores for normalized-fibular position indicate that it has little ability to predict CAI alone.

Abstract
OBJECTIVE To systematically review whether there is an association between hip range of motion (ROM) and nonspecific low back pain (NSLBP). DATA SOURCES MEDLINE, EMBASE, Cochrane library, PsychINFO, CINAHL and AMED databases were searched from year of inception until October 31st, 2018, using a combination of LBP and hip joint search terms. Commonly cited journals were also hand searched within the previous two years. STUDY SELECTION Two reviewers independently screened identified articles, by title and abstract and then by full-text. After first round screening of 2908 identified records, 248 progressed to full-text screening. Due to the heterogeneity of studies identified, post hoc inclusion criteria of English language, studies comparing subjects with NSLBP and healthy controls, cross-sectional design, and clinical measures of hip ROM were applied. Twenty-four records were finally included. DATA EXTRACTION Extracted data included population characteristics, duration and severity of NSLBP, hip movement direction, testing position, measurement tool and between-group difference. The Quality Assessment Tool for Observational Cohort and Cross-Sectional Studies was used to assess for study bias. DATA SYNTHESIS Hip flexion ROM was measured in seven studies, extension in 13, internal rotation (IR) in 14, external rotation (ER) in 13, abduction in six, and adduction in only two studies. Among all directions tested, IR ROM was reported in more studies as significantly reduced in NSLBP subjects compared to healthy individuals. Overall the quality of evidence was very low. Common sources of study bias included lack of sample size justification, blinding of outcome assessors, adjusting for key confounders, and poor reporting. CONCLUSION There is very low-quality evidence to support an association between limited hip ROM and NSLBP. Limited hip IR ROM was the only movement impairment found to be significantly associated with NSLBP, however this should be viewed with caution due to the low-quality supportive evidence. Further studies are needed.

Abstract
Determining the signal quality of surface electromyography (sEMG) recordings is time consuming and requires the judgement of trained observers. An automated procedure to evaluate sEMG quality would streamline data processing and reduce time demands. This paper compares the performance of two supervised and three unsupervised artificial neural networks (ANNs) in the evaluation of sEMG quality. Manually classified sEMG recordings from various lower-limb muscles during motor tasks were used to train (n=28,000), test performance (n=12,000) and evaluate accuracy (n=47,000) of the five ANNs in classifying signals into four categories. Unsupervised ANNs demonstrated a 30-40% increase in classification accuracy (>98%) compared with supervised ANNs. AlexNet demonstrated the highest accuracy (99.55%) with negligible false classifications. The results indicate that sEMG quality evaluation can be automated via an ANN without compromising human-like classification accuracy. This classifier will be publicly available and will be a valuable tool for researchers and clinicians using electromyography.

Abstract
This cross-sectional study investigated musculoskeletal discomfort and computer use in university staff, through the use of online questionnaires. Results showed a high prevalence of staff reported musculoskeletal discomfort during the preceding year (80%), with neck (60%), shoulder (53%) and lower back discomfort (47%) being the most common. Most believed discomfort was caused by work, although neck discomfort was significantly less in those reporting excellent mental health (OR 0.44, p < 0.01). Computer navigation was performed primarily by mouse (77%); however, using a touch pad increased the odds (OR 1.17, p < 0.01) of wrist discomfort and the belief it was caused by work (OR 1.19, p < 0.01). Few staff attended ergonomic training (16%) or requested workstation assessments (26%). However, high rates of staff reporting musculoskeletal discomfort sought professional treatment (range: 35.2% wrist/hand to 65.0% shoulder). Strategies are needed to address uptake of preventive measures and reduce reliance on medical treatments following musculoskeletal discomfort in universities.

Abstract
Background Verbal augmented feedback (VAF) is commonly used in physiotherapy rehabilitation of individuals with lower extremity musculoskeletal dysfunction or to induce motor learning for injury prevention. Its effectiveness for acquisition, retention and transfer of learning of new skills in this population is unknown. Objectives First, to investigate the effect of VAF for rehabilitation and prevention of lower extremity musculoskeletal dysfunction. Second, to determine its effect on motor learning and the stages of acquisition, retention and transfer in this population. Design Systematic review designed in accordance with the Centre for Reviews and Dissemination and reported in line with Preferred Reporting Items for Systematic Review and Meta-analysis. Method MEDLINE, Embase, PubMed and five additional databases were searched to identify primary studies with a focus on VAF for prevention and rehabilitation of lower extremity musculoskeletal dysfunction. One reviewer screened the titles and abstracts. Two reviewers retrieved full text articles for final inclusion. The first reviewer extracted data, whereas the second reviewer audited. Two reviewers independently assessed risk of bias and quality of evidence using Cochrane Collaboration’s tool and Grading of Recommendations Assessment, Development and Evaluation, respectively. Results Six studies were included, with a total sample of 304 participants. Participants included patients with lateral ankle sprain (n=76), postoperative ACL reconstruction (n=16) and healthy individuals in injury prevention (n=212). All six studies included acquisition, whereas retention was found in five studies. Only one study examined transfer of the achieved motor learning (n=36). VAF was found to be effective for improving lower extremity biomechanics and postural control with moderate evidence from five studies. Conclusion VAF should be considered in the rehabilitation of lower extremity musculoskeletal dysfunctions. However, it cannot be unequivocally confirmed that VAF is effective in this population, owing to study heterogeneity and a lack of high-quality evidence. Nevertheless, positive effects on lower extremity biomechanics and postural control have been identified. This suggests that further research into this topic is warranted where an investigation of long-term effects of interventions is required. All stages (acquisition, retention and transfer) should be evaluated.

Abstract
A cross-sectional survey was conducted in a regional area in Australia to measure nurses' perceptions, practices, and knowledge in regard to providing healthy lifestyle advice to people who are overweight or obese. Responses were compared between geographic regions. Participation was voluntary and anonymous. Of the 79 nurse participants, 68% considered that provision of healthy lifestyle advice was within their scope of practice. Only 28% reported frequently estimating body mass index in the practice setting. Nurses often recommended increasing activity levels (44%), but recommended reducing daily caloric intake less often (25%). Nurses' knowledge about weight management was variable and the proportion of correct answers to knowledge items ranged from 33-99%. Nurses have many opportunities to deliver healthy lifestyle advice in a range of practice settings. The variation in practices and knowledge of nurses indicates a need for improved healthy lifestyle education for undergraduate and practicing nurses.

Abstract
Early-phase clinical development in oncology has evolved dramatically with the deciphering of the human genome in 2004. Genomic analysis and the tools identifying genetically disrupted pathways within a patient's tumor have been a driving force for personalized medicine and for the development of highly targeted novel therapies. Tumors are often genetically heterogeneous, with multiple concurrent genetic abnormalities. On the other hand, tumors arising from different tissues may share identical molecular drivers.

Abstract
Obesity is a global issue, with healthcare practitioners increasingly involved in clinical interactions with people who are overweight or obese. These interactions are opportunities to provide evidence-based healthy lifestyle advice, and impact on public health. This study used a cross-sectional survey of Australian healthcare practitioners to investigate what influenced the provision of healthy lifestyle advice to obese and overweight clients. A modified theory of planned behavior was used to explore knowledge translation processes. Knowledge translation was linked to three factors: (i) a healthcare practitioner's education and confidence in the currency of their knowledge; (ii) personal characteristics - whether they accepted that providing this advice was within their domain of practice; and (iii) the existence of organizational support structures, such as access to education, and best practice guidelines. To fulfill the potential role healthcare practitioners can play in the provision of evidence-based health promotion advice requires organizations to provide access to practice guidelines and to instill a belief in their workforce that this is a shared professional domain.

Abstract
The significance of a helicopter patrol procedure directed toward prevention of home burglaries was evaluated from experimental and cost-benefit perspectives. The helicopter patrolled one city zone from 9 a.m. to 5 p.m. for two 12-day periods. Each 12-day period was separated by a baseline period in which only normal patrol-car levels were maintained. Significantly reduced burglary levels during the intervention periods, compared to baseline periods, documented the experimental significance of the helicopter procedure. The cash costs of implementing the patrol procedure were compared to two estimates of the resulting cash benefits. This latter cost-benefit analysis was supplemented by a discussion of the intangible costs and benefits of the helicopter procedure. Taken together, these analyses documented that the marginal costs of the helicopter intervention were exceeded by all estimates of benefits.

Calculating pass-through and outlier payments under APCs. HEALTHCARE FINANCIAL MANAGEMENT : JOURNAL OF THE HEALTHCARE FINANCIAL MANAGEMENT ASSOCIATION 2001; 55:54-7.

Abstract
Medicare's outpatient prospective payment system is based on ambulatory payment classifications (APCs) that group services into categories for payment. The relative weight of each APC is based on the median operating and capital cost of the services within the group based on hospital outpatient claims data for 1996. These data, however, do not accurately reflect the cost of innovative medical devices, drugs, and biologicals currently in use. To account for these developments, the Balanced Budget Refinement Act of 1999 (BBRA) established the transitional pass-through payment system to provide additional amounts above the applicable APC rate for innovative medical devices, drugs, and biologicals. The BBRA also established a cost-outlier adjustment. Successfully calculating payments for pass-through and outlier devices requires that financial managers have a thorough knowledge of the medical devices, drugs, and biologicals being used in their outpatient surgery departments.

Abstract
Although isolated lower motor neuron disease has been reported as a paraneoplastic complication, it has not been previously described, in association with anti-Hu antibody. We report a 51-year-old man in whom weakness heralded the presence of a small-cell cancer of the lung. His neurological disorder was characterized by an unremitting progression of limb, neck, and chest wall weakness and wasting that commenced and remained predominant in the upper limbs. Electrophysiological studies demonstrated widespread denervation and examination of a muscle biopsy specimen showed evidence of acute and chronic denervation. High titers of anti-Hu antibody were detected in the serum and cerebrospinal fluid. Neither objective measures of strength nor titers of anti-Hu antibody responded to corticosteroids, cyclophosphamide, intravenous immunoglobulins, or plasmapheresis. Death from the complications of motor neuron disease ensued 23 months after the onset of weakness. Autopsy revealed tumor in the lung and on pleural and peritoneal surfaces. There was a loss of anterior horn cells in the spinal cord. Despite the absence of symptomatic cerebellar disease, a decrease in the number of Purkinje cells was also detected.

Abstract
A total of 113 patients with infection due to human T-cell leukemia virus type 1 (HTLV-I) were evaluated at the University of Miami from January 1988 to March 1993. Forty patients were identified with adult T-cell leukemia/lymphoma (ATLL) and 63 with HTLV-I-associated myelopathy (HAM). Three had concomitant ATLL and HAM. Two HAM patients co-infected with human immunodeficiency virus type 1 (HIV-I) developed clonal lymphoproliferative disease during the study period. Patients with ATLL have a poor prognosis; multiple chemotherapy regimens including high-dose cytotoxic agents have been utilized with a small impact on survival. Most of our patients are currently treated with experimental regimens. Rheumatologic or autoimmune illnesses were identified, mostly in HAM patients, and a small number developed immunodeficiencies in the absence of other definable etiologic factors. Most of the patients were immigrants from areas of endemicity in the Caribbean basin, although many Americans were also recognized. HTLV-I/II infection was diagnosed serologically and typed as HTLV-I by polymerase chain reaction (PCR) or a modified Western blot when a DNA sample was not available. In 24 of 40 patients with ATLL, Southern blot hybridization performed on DNA extracted from peripheral blood lymphocytes or tumor tissue demonstrated clonal HTLV-I integration. In South Florida, ATLL and HAM are now seen frequently. Since HTLV-I infection is associated with a 4% lifetime risk of developing ATLL and an additional 0.25% lifetime risk for developing HAM, a large pool of asymptomatically infected individuals must exist here.(ABSTRACT TRUNCATED AT 250 WORDS)

Abstract
Although intracranial gliomas carry a poor long-term prognosis, retreatment at the time of tumor progression may prolong survival and maintain or improve the quality of life. Thirty-three patients who underwent retreatment with surgery, radiotherapy, and chemotherapy were reviewed retrospectively. Median survival after initiation of retreatment was 8 months for glioblastoma, 13 months for anaplastic astrocytoma, 22 months for astrocytoma, and 47 months for oligodendroglioma/mixed glioma. Survival was significantly better for younger patients and for those with better functional status. One third of patients were neurologically improved by surgery. Surgical morbidity was minimal (2.1%); there was no surgical mortality. Chemotherapy and radiotherapy produced expected adverse reactions. Retreatment of intracranial gliomas carries acceptable risk and is beneficial in selected patients. Decisions regarding retreatment must be carefully individualized with consideration of the quality of life and the wishes of the patient and family.

Abstract
Jamaican Neuropathy of the ataxic type (tropical ataxic neuropathy [TAN] and spastic type (tropical spastic paraparesis [TSP]) have been recognized for over a century in Jamaica. The recent association of TSP with HTLV-I (TSP/HAM) is now well established. We now present evidence for a possible association between a TAN-like illness with HTLV-II in four females aged 34-49. All presented with ataxic gait and all four have prominent mental changes. Three of the four also have minor motor deficits with urinary frequency and two have nocturnal leg cramps. All have serum antibody and all had PCR evidence of HTLV-II infection. Antibody to HTLV-II is present in CSF from two subjects. The distinctive picture of prominent ataxia and altered mental status in these subjects contrasts with a predominantly myelopathic picture seen in TSP/HAM.

Abstract
Human T-cell lymphotropic virus type one (HTLV-1) is associated with tropical spastic paraparesis or HTLV-I--associated myelopathy. We report 2 women with a spastic ataxic illness similar to HTLV-I--associated myelopathy infected solely with HTLV-II. Identification of HTLV-II infection was made serologically, by polymerase chain reaction, and by viral culture (in 1 woman). One woman, treated with 200 mg of danazol orally, three times daily, had pronounced improvement in ambulation, nocturnal spasticity, and nighttime urinary frequency. It appears that infection with HTLV-II may cause an illness similar to HTLV-I--associated myelopathy, but distinguished by the presence of ataxia.

Abstract
We performed a serologic survey for antibodies to HTLV-I/II in the course of a longitudinal study of the neurologic complications of HIV-1 infection. Nine (3.7%) of 242 HIV-1 seropositive subjects and none of 60 HIV-1 seronegative control subjects had antibodies to HTLV-I/II by ELISA. Western blot and polymerase chain reaction confirmed the presence of HTLV-I in 2 subjects and HTLV-II infection in 2 others. Both HIV-1/HTLV-I coinfected subjects and 1 HIV-1/HTLV-II coinfected subject had a slowly progressive myelopathy clinically identical tropical spastic paraparesis/HTLV-I-associated myelopathy (TSP/HAM). The presence of a myelopathy resembling TSP/HAM in the coinfected subjects suggests that HIV-1 may enhance the expression of neurologic disease caused by HTLV. Patients with a progressive myelopathy occurring in association with HIV-1 infection should be serologically tested for the presence of HTLV. Establishing dual infection has therapeutic and prognostic import as 1 of the HIV-1/HTLV-I subjects substantially improved with corticosteroids and the HIV-1/HTLV-II subject with myelopathy had a marked improvement in the absence of therapeutic intervention.

Abstract
We describe a 34-year-old man with a 17-year history of multifocal fibrosclerosis resulting in unique neurologic complications. Episcleritis, orbital pseudotumor, and sclerosing cholangitis accompanied a florid intracranial inflammatory pachymeningitis. The latter was associated with blindness, multiple cranial neuropathies, pseudotumor cerebri, and seizures. Extensive investigation failed to reveal an etiology. Corticosteroids were ineffective in preventing progression of the disorder, and the value of antineoplastic therapy was uncertain. Multifocal fibrosclerosis, a rare disorder, may result in a confusing array of neurologic manifestations.

Abstract
We reviewed 57 patients, who during the last four years had cholecystokinin cholecystography during evaluation of abdominal pain, and found this test to be reliable for diagnosing chronic acalculous cholecystitis. Eighty-eight percent of the patients in whom abdominal pain was reproduced during cholecystokinin cholecystography and who had less than 50% contraction of the gallbladder were cured or improved after cholecystectomy.
