Strength and Balance in Recreational Golfers Aged Over 80 Years.

Muscle strength and balance decrease with age, particularly in those over 80. Playing golf is associated with greater strength and balance in 65-79-year-olds, but it is not known if this occurs in the over 80s. Strength and balance of golfers aged over 80 years were assessed and compared with data obtained by the same research group on golfers and nongolfers aged 65-79 years.

Non-specific diagnostic labels for musculoskeletal conditions foster positive views about prognosis and non-invasive management but require clear explanation: a systematic review.

Questions: What are patient and public perceptions of diagnostic labels for musculoskeletal pain? How do these labels influence beliefs, emotions and treatment preferences?

Design: Systematic review and qualitative meta-synthesis.

Participants: People with musculoskeletal pain or people presented with hypothetical vignettes of musculoskeletal pain.

Intervention: Diagnostic labels for musculoskeletal pain.

Background information was collected from the program manager and through one-on-one interviews with the program's founders and current chairman. A survey was administered to past observers to capture feedback.

Vertical pelvic movement asymmetry and lameness location in ipsilateral combined forelimb and hindlimb lameness cases.

Background: Compensatory vertical head and pelvis movement asymmetry may occur in trotting horses with a primary cause of lameness in one end of the body due to the weight shifting between limbs, leading to apparent combined forelimb and hindlimb lameness (CFHL). Little is known about CFHL patterns observed with body-mounted inertial sensors (BMIS) and regardless of their underlying mechanisms, compensatory and secondary lameness may complicate the definitive identification of the primary causes of lameness.

Objective: Determine associations between vertical pelvic movement asymmetry and location of primary lameness in ipsilateral CFHL cases where hindlimb lameness is solely impact or push-off type.

Strength and Balance in Recreational Golfers and Non-Golfers Aged 65-79 Years in Community Settings.

Inactive older adults tend to have decreased strength and balance compared with their more active peers. Playing golf has the potential to improve strength and balance in older adults. The aim of the study was to compare the strength and balance of recreational golfers with non-golfers, aged 65-79 years.

How Do the Outcomes of Radiation-Associated Pelvic and Sacral Bone Sarcomas Compare to Primary Osteosarcomas following Surgical Resection?

Radiation-associated sarcoma of the pelvis and/or sacrum (RASB) is a rare but challenging disease process associated with a poor prognosis. We hypothesized that patients with RASB would have worse surgical and oncologic outcomes than patients diagnosed with primary pelvic or sacral bone sarcomas. This was a retrospective, multi-institution, comparative analysis.

Staging and Surveillance of Myxoid Liposarcoma: Follow-up Assessment and the Metastatic Pattern of 169 Patients Suggests Inadequacy of Current Practice Standards.

Background: Unlike other sarcoma subtypes, myxoid liposarcoma (MLS) has a propensity for extra-pulmonary metastases. Computed tomography (CT) scan of the chest, abdomen, and pelvis has become an accepted practice for surveillance. However, recent literature suggests that this may be inadequate.

Platelet-rich plasma (PRP) in osteoarthritis (OA) knee: Correct dose critical for long term clinical efficacy.

Despite encouraging results reported with regards to Platelet-rich plasma (PRP) application in osteoarthritis (OA) knee, still critical issues like conclusive structural evidence of its efficacy, standard dose and good manual method of preparation to obtain high yield remains unanswered. Present study is an attempt to optimise the dose and concentration of therapeutic PRP and its correlation with structural, physiologic efficacy with a new manual method of PRP preparation. A total of one hundred and fifty patients were randomized to receive either PRP (10 billion platelets) or hyaluronic acid (HA; 4 ml; 75 patients in each group) and followed up till 1 year.

The role of Denosumab in joint preservation for patients with giant cell tumour of bone.

Aims: Local recurrence remains a challenging and common problem following curettage and joint-sparing surgery for giant cell tumour of bone (GCTB). We previously reported a 15% local recurrence rate at a median follow-up of 30 months in 20 patients with high-risk GCTB treated with neoadjuvant Denosumab. The aim of this study was to determine if this initial favourable outcome following the use of Denosumab was maintained with longer follow-up.

Developing and Assessing the Feasibility of Implementing a Surgical Objective Structured Clinical Skills Examination (S-OSCE).

Objective: To1 describe the development and evaluate the feasibility of a surgical objective structured clinical examination (OSCE) for the purpose of competency assessment based on the Royal College of Canada's CanMEDS framework.

Design: A unique surgical OSCE was developed to evaluate the clinical and surgical management of common orthopaedic problems using simulated patients and cadaveric specimens. Cases were graded by degree of difficulty (less complex, complex, more complex) Developing an assessment tool with significant resource utilization and good correlation with traditional methods is challenging.

Comparison of results for body-mounted inertial sensor assessment with final lameness determination in 1,224 equids.

Objective: To compare results for initial body-mounted inertial sensor (BMIS) measurement of lameness in equids trotting in a straight line with definitive findings after full lameness evaluation.

Animals: 1,224 equids.

Procedures: Lameness measured with BMIS equipment while trotting in a straight line was classified into categories of none, forelimb only, hind limb only, and 8 patterns of combined forelimb and hind limb lameness (CFHL).

Midterm Success of a Custom, Non-Fluted, Diaphyseal, Press-Fit Stem Used With a Tumor Megaprosthesis System.

Background: High rates of aseptic loosening with cemented prostheses have led to increased utilization of uncemented stems in the setting of megaprosthetic reconstruction. Theoretic concerns of rotational instability resulted in early stem designs with de-rotational mechanisms such as flutes or side plates. However, these designs have their own associated complications, and mechanical data suggest they are unnecessary.

A systematic review of the discriminating biomechanical parameters during the single leg squat.

Objective: To determine whether there are common biomechanical parameters when analysing the single leg squat movement to compare pathological and non-pathological groups and whether these parameters are able to effectively distinguish between groups.

Methods: Five electronic databases were searched using MESH terms, keywords and phrases across four constructs: squat, biomechanical measures, region of interest, study design. Studies were selected based on inclusion of a quantitative biomechanical measure, compared between a pathological and a non-pathological group, and participants performed a single leg squat movement.

Accuracy of movement quality screening to document effects of neuromuscular control retraining exercises in a young ex-footballer with hip and groin symptoms: A proof of concept case study.

Hip and groin pain is common in footballers and altering movement patterns can reduce symptoms. Observational tests of movement control are thought to identify abnormal movement patterns, but their accuracy needs yet to be confirmed by comparison with an objective measure. To assess the accuracy, using 3D motion analysis, of observational movement control tests and their ability to detect changes, and document changes in symptoms following a neuromuscular control exercise programme in an ex-footballer with hip and groin pain.

An attempt to detect lameness in galloping horses by use of body-mounted inertial sensors.

OBJECTIVE To evaluate head, pelvic, and limb movement to detect lameness in galloping horses. ANIMALS 12 Thoroughbreds. PROCEDURES Movement data were collected with inertial sensors mounted on the head, pelvis, and limbs of horses trotting and galloping in a straight line before and after induction of forelimb and hind limb lameness by use of sole pressure.

Global Prevalence of Myopia and High Myopia and Temporal Trends from 2000 through 2050.

Purpose: Myopia is a common cause of vision loss, with uncorrected myopia the leading cause of distance vision impairment globally. Individual studies show variations in the prevalence of myopia and high myopia between regions and ethnic groups, and there continues to be uncertainty regarding increasing prevalence of myopia.

Design: Systematic review and meta-analysis.

A Simple Method for Estimating the Economic Cost of Productivity Loss Due to Blindness and Moderate to Severe Visual Impairment.

Purpose: To estimate the annual loss of productivity from blindness and moderate to severe visual impairment (MSVI) using simple models (analogous to how a rapid assessment model relates to a comprehensive model) based on minimum wage (MW) and gross national income (GNI) per capita (US$, 2011).

Methods: Cost of blindness (COB) was calculated for the age group ≥50 years in nine sample countries by assuming the loss of current MW and loss of GNI per capita. It was assumed that all individuals work until 65 years old and that half of visual impairment prevalent in the ≥50 years age group is prevalent in the 50-64 years age group.

Effectiveness of the GnRH agonist Deslorelin as a tool to decrease levels of circulating testosterone in zebra finches.

Songbirds are widely used in studies of the neurobiology underlying learning, memory and performance of the sounds used in vocal communication. Development and activity of neurons in many brain sites implicated in those behaviors are closely related to levels of circulating testosterone. Approaches to understand the effects of testosterone in songbirds are presently limited to testosterone implants, which elevate testosterone levels to supraphysiological values, or castration, which eliminates gonadal production of testosterone.
