Abstract
Objectives To describe the incidence, characteristics and burden of tackle-event injuries in under-19 schoolboy Rugby Union in Ireland comparing the profile of tackler and ball-carrier injuries independently; and to examine the burden on school absenteeism.

Purpose
A biopsychosocial assessment of a person with low back pain (LBP) should include the detection of psychological risk factors. Pragmatically, clinicians often use their clinical impression rather than questionnaires to screen for psychological risk factors. This scoping review explores how accurately depression, anxiety, and psychological di...
Background
The prevalence of peripheral arterial disease (PAD) is increasing globally. An increase in PAD in an ageing population inevitably results in an increase in incidence of Chronic Limb Threatening Ischemia (CLTI). Loss of a limb is a life-changing event with immeasurable cost to the individual, while the potential financial benefit of savin...
Female Rugby Union players were affected by contact breast injuries (CBI) and exercise-induced breast pain (EIBP). Hundred and eighty-two female Rugby players from 25 different countries reported incurring a CBI or EIBP which affected sport performance. A higher percentage of 7s players (7s: 64.3%, 15s: 51.9%) reported at least one CBI over a 12-mo...
Summary

Background
Pain is a prevalent, debilitating condition among older adults. Much evidence on this topic comes from cohort studies, which may be affected by attrition and measurement bias. Little is known about the impact of these biases on pain estimates for European older adults. Additionally, there is a lack of longitudinal research on pain and so...
Background

Background
The shoulder has been reported as a frequent location of injury in adult professional and amateur rugby, with match injury incidence rates ranging from 1.8 to 3 per 1000 player-hours (h). An increased understanding of the incidence and mechanism of shoulder injuries in school rugby players is vital to establish effective injury preventiv...
Training load (TL) is a modifiable risk factor that may provide practitioners with opportunities to mitigate injury risk and increase sports performance. A regular problem encountered by practitioners, however, is the issue of missing TL data. The purpose of this study was to examine the impact of missing TL data in team sports and to offer a pract...
Background:

Background:
Pain is common in older adults, and associated with increased morbidity and reduced quality of life. Recent research has highlighted different classes of older adults with pain, each with differing impacts on their life. It has not yet been investigated if, and how, such classes change over time and what influences individuals to prosp...
Background
One-size-fits-all interventions reduce chronic low back pain (CLBP) a small amount. An individualised intervention called cognitive functional therapy (CFT) was superior for CLBP compared with manual therapy and exercise in one randomised controlled trial (RCT). However, systematic reviews show group interventions are as effective as one...

Background:
Persistent strength deficits secondary to Achilles tendinopathy (AT) have been postulated to account for difficulty engaging in tendon-loading movements, such as running and jumping, and may contribute to the increased risk of recurrence. To date, little consensus exists on the presence of strength deficits in AT. Consequently, researc...
Background:
The Agatston Calcium Score is a predictor of major adverse cardiovascular events but it is unable to identify high-risk lesions. Recent research suggests that examining calcification phenotype could be more indicative of plaque stability.

Pain significantly restricts the quality of life and well-being of older adults. With our increasingly ageing population, it is important to examine whether differing classes of biopsychosocial risk factors can predict the development of pain in older adults. Latent class analysis (LCA) provides a model-based approach to identifying underlying subg...
Background:
Many patients reporting musculoskeletal pain present to Primary Care Physiotherapy with costly comorbid overlapping complaints that remain medically unexplained. These subjective health complaints (SHC) incorporate coexisting multi-site musculoskeletal pain and varied non-musculoskeletal complaints (e.g. anxiety, tiredness). The role o...
Objectives: Persistent poor sleep is associated with a range of adverse health outcomes. Sleep is considered the main method of recovery in athletes; however, studies report that a significant number of athletes are getting insufficient sleep.

Study design:
A case series was carried out.
Introduction:
There is a lack of evidence exploring the effectiveness of group exercise classes for people with nonspecific shoulder pain (NSSP). Also, there is a lack of research that measures potential reductions in thoracic kyphosis after exercise interventions in people with NSSP.
Purpose of the...
Background/aim
Exercise imparts a load on tendon tissue that leads to changes in tendon properties. Studies suggest that loading immediately reduces tendon thickness, with a loss of this response in symptomatic tendinopathy. No studies investigating the response of tendon dimensions to load for the rotator cuff tendons exist. This study aimed to ex...

Psychosocial factors are considered to be important mediators following exercise interventions. Despite the recognition of the importance of psychosocial variables in persistent MSK disorders, there is a distinct la...
Background
Ultrasound [US] imaging is commonly used to visualise tendon structure. It is not clear whether the presence of structural abnormalities in asymptomatic tendons predicts the development of future tendon symptoms in the Achilles or patellar tendon. This led to considerable uncertainty in the management of sporting populations with a high...

Previous research in Irish dancing (ID) has recorded high levels of pain/injury. Screening protocols in other genres have been developed to identify at-risk dancers. The aims of the study were to examine the factors that relate to absence from dancing because of musculo-skeletal pain/injury in ID, and to inform guidelines for the development of an...
Objective evidence suggests that sedentary behaviours (SB) increase throughout adolescence at the expense of light intensity physical activity (LIPA), particularly in females (Mitchell et al., 2012). The vast majority of studies that have objectively measured physical activity (PA) have relied on thresholds to estimate SB rather than directly exami...
Non-specific chronic low back pain (NSCLBP) is a very common and costly musculoskeletal disorder associated with a complex interplay of biopsychosocial factors. Cognitive functional therapy (CFT) represents a novel, patient-centred intervention which directly challenges pain-related behaviours in a cognitively integrated, functionally specific and...
