The primary objective of this review was to create a 'trustworthy,' living systematic review and meta-analysis for the application of manual therapy interventions in treating patients with shoulder dysfunction. Included studies were English-language randomized controlled trials published between 1/1/2010 and 8/3/2023, with searches performed in: PubMed, Cochrane Central Register of Controlled Trials (CENTRAL), CINHAL, ProQuest Nursing & Allied Health, EBSCO Medline, and PEDro. The population of focus included adults 18 years and older with musculoskeletal impairments related to shoulder dysfunction.

Temporomandibular (TM) disorders afflict many people globally and, despite the presence of existing peer-reviewed material that assists conservative orthopedic providers, recent advances in knowledge indicate that updated resources are required for students, clinicians, and educators. This two-part series builds off previously published material to present newer supplementary information that can be useful during the evaluation and management processes. Content in Part 1 of this series includes a discussion about the factors that have been shown to contribute to TM disorders, an updated perspective of relevant pain science, a discussion of self-report outcome measures, and various different topics related to the examination of patients with TM disorders.

Background: Preprocessed research resources are believed to be highly 'trustworthy' when translating research to clinical practice. However, the overall 'trustworthiness' is unknown if this evidence contains randomized clinical trials (RCTs) where prospective has not been/cannot be verified, has low confidence in estimated effects, and if they are not up to date.

Objectives: This protocol will be used to create a baseline benchmark for a series of trustworthy living systematic reviews (SRs) regarding manual therapy interventions.

Introduction: It is unknown if verified prospective registration of systematic reviews (SRs) and the randomized clinical trials (RCTs) that they use affect an SR's methodological quality on A MeaSurement Tool to Assess Systematic Reviews 2 (AMSTAR 2).

Methods: Data originated from interventional SRs published in International Society of Physiotherapy Journals Editors (ISPJE) member journals, indexed in MEDLINE, between 1 January 2018 and 18 August 2021. Blinded reviewers identified the SRs and extracted the data for the variables of interest for the SRs and the RCTs.

Objectives: To determine if there are any statistically significant associations between: 1) randomized clinical trials (RCTs) investigating physical therapy musculoskeletal interventions, 2) journal impact factor (JIF), 3) frequency of RCT citation, 4) whether prospective intent was identifiable, and 5) the Physiotherapy Evidence Database (PEDro) scores.

Methods: MEDLINE indexed RCTs addressing musculoskeletal interventions published between January 2016 and July 2020 in physical therapy journals were included. Two blinded reviewers identified the RCTs and extracted the variables of interest.

Background: Few studies have addressed the appropriate joint mobilization dosage for neck pain. Furthermore, the efficacy of manual therapy in patients with post-spinal fusion neck pain is unreported.

Case Description: A 63-year-old man with a 2-year history of unresolved neck pain post-cervical fusion presented to therapy with an exacerbation of neck and left-shoulder pain.

Aim: Gastro-oesophageal reflux is routinely diagnosed with invasive intraluminal impedance pH probe monitoring. This study aimed to determine whether gastric pepsin A detected in saliva of children correlates with gastro-oesophageal reflux.

Methods: Patients undergoing probe monitoring were prospectively recruited between 2014 and 2016 at a paediatric hospital.

Background: Advanced practice physiotherapy (APP) rights are part of the evolution of the Physical Therapy profession. To date, no study has investigated musculoskeletal APP rights within the World Confederation for Physical Therapy (WCPT).

Objective: To investigate musculoskeletal APP rights for physical therapists worldwide and examine the relationship between level of education (entry and post-professional) and direct access for countries that are vs.

Objectives: The purpose of this investigation was to establish an international baseline of the quantity of physical therapist education on temporomandibular disorders (TMD) during post-professional Orthopedic Manual Physical Therapy (OMPT) education.

Methods: An electronically distributed survey was sent to programs and data analyzed for trends, including a comparison of TMD and cervical spine disorders education. Current data were compared to pre-existing data from the United States.

Objectives: The aim of the study was to quantify the diagnostic yield of upper endoscopy in children with gastroparesis and to develop a clinical model for gastroparesis using common symptoms and screening blood tests.

Methods: We retrospectively reviewed charts of 196 patients of age 4 to 18 years evaluated for gastroparesis between 2009 and 2013. All patients completed a standard solid-phase gastric emptying scan and upper endoscopy within a 12-month period.

Objective: The purpose of this investigation was to establish a baseline of physical therapist education on temporomandibular disorders (TMD)-related topics during credentialed orthopedic manual physical therapy fellowship training and compare it to cervical spine disorders education.

Method: An online survey was distributed electronically to each fellowship program credentialed by the American Physical Therapy Association (APTA) and recognized by the Academy of Orthopedic Manual Physical Therapists (AAOMPT). Data were analyzed to compare overall exposure to TMD educational content, including a direct comparison of TMD and cervical spine disorders education.

Appropriate management of temporomandibular disorders (TMD) requires an understanding of the underlying dysfunction associated with the temporomandibular joint (TMJ) and surrounding structures. A comprehensive examination process, as described in part 1 of this series, can reveal underlying clinical findings that assist in the delivery of comprehensive physical therapy services for patients with TMD. Part 2 of this series focuses on management strategies for TMD.

Temporomandibular disorders (TMD) are a heterogeneous group of diagnoses affecting the temporomandibular joint (TMJ) and surrounding tissues. A variety of methods for evaluating and managing TMD have been proposed within the physical therapy profession but these sources are not peer-reviewed and lack updates from scientific literature. The dental profession has provided peer-reviewed sources that lack thoroughness with respect to the neuromusculoskeletal techniques utilized by physical therapists.

Objective: The objective of this study was to study the association between pepsin in tracheal aspirate samples and the development of bronchopulmonary dysplasia in preterm infants.

Methods: Serial tracheal aspirate samples were collected during the first 28 days from mechanically ventilated preterm neonates. Bronchopulmonary dysplasia was defined as the need for supplemental oxygen at 36 weeks' postmenstrual age.

Objectives: To examine psychosocial differences in diagnostic subgroups of children with recurrent abdominal pain (RAP).

Methods: Children meeting Apley's 1975 definition of RAP were divided according to physician ratings into three subgroups, based on the Rome II diagnostic criteria of functional gastrointestinal disorders: functional dyspepsia (n=17), irritable bowel syndrome (n=18), and functional abdominal pain (n=27). Groups were compared using measures of (a) child psychopathology, (b) parent psychopathology, and (c) child pain, somatization, and functional disability.
