Unlabelled: Measurement properties of the Working Alliance Inventory (WAI) and its various translations and adaptations for specific target groups have been investigated for over 30 years. No systematic review analyzing studies on measurement properties of the WAI has been conducted to date. COnsensus-based Standards for the selection of health Measurements INstruments (COSMIN) were developed for conducting high-quality systematic reviews on measurement properties in a transparent and standardized way.

Study Design: A cross-sectional inter-examiner agreement and reliability study on fresh frozen cadaver shoulders.

Background: Musculoskeletal ultrasound (MSU) is frequently used by physical therapists and radiologists to improve specific diagnosis in rotator cuff related pathology. The evaluation of the rotator cable seems to be important as stabilizing structure when cuff tears occur.

Study Design: A cross-sectional inter-examiner agreement and reliability study among physical therapists in primary care.

Background: musculoskeletal ultrasound (MSU) is frequently used by physical therapists to improve specific diagnosis in patients with shoulder pain, especially for the diagnosis rotator cuff tendinopathy (RCT) including tears.

Objectives: To estimate the inter-examiner agreement and reliability in physical therapists using MSU for patients with shoulder pain.

Objective: To assess the effect of a personalized newsletter compared with a standard newsletter on patient recruitment in physiotherapy research.

Methods: We performed a cluster-randomized trial including 120 physiotherapists who recruited patients for a prospective cohort and were randomly assigned to either receiving personalized feedback in a newsletter (intervention group) or a standard newsletter (control group). We calculated the difference in the number of patients included in the study corrected for inclusion time between both groups.

Study Design: Prospective cohort study including patients with shoulder pain in primary care physiotherapy.

Background: There is an increased tendency to use diagnostic ultrasound to aid the diagnostic strategy and target treatment. It is a relatively cheap and accessible imaging technique but the implications for practice and patients are unknown.

Study Design: A systematic overview of the literature and an agreement study.

Objectives: The aim of this study is to explore the inter-professional agreement of diagnostic musculoskeletal ultrasound (DMUS) between physical therapists (PT) and radiologists, using a new classification strategy based upon the therapeutic consequences in patients with shoulder pain.

Background: DMUS is frequently used by PTs, although the agreement regarding traditional diagnostic labels between PTs and radiologists is only fair.

Questions: Is it possible to replace the Shoulder Pain and Disability Index (SPADI) with a single substitute question for people with shoulder pain, when measuring disability and how well does this substitute question perform as a predictor for recovery.

Design: A prospective cohort study.

Participants: A total of 356 patients with shoulder pain in primary care.

Background: Shoulder pain is one of the three main musculoskeletal complaints and more than 50% of the patients have symptoms longer than 6 months. Until now, limited data exist about the content of physiotherapy for patients with shoulder pain in primary care.

Objective: Describe current physiotherapeutic diagnostic- and therapeutic management, including the use of diagnostic ultrasound, in patients with shoulder pain in primary care.

Study Design Clinical measurement study, prospective cohort design. Background Shoulder pain is a common disorder, and treatment is most often focused on a reduction of pain and functional disabilities. Several reviews have encouraged the use of the Shoulder Pain and Disability Index (SPADI) to objectify functional disability.

Background: Health care providers need prognostic factors to distinguish between patients who are likely to recover and those who are not likely to recover.

Objective: The aim of this study was to: (1) describe the clinical course of recovery and (2) identify prognostic factors of recovery in patients with shoulder pain at the 26-week follow-up.

Design: A prospective cohort study was carried out in the Netherlands and included 389 patients who consulted a physical therapist for a new episode of shoulder pain.

Purpose: The increasing use of diagnostic imaging has led to high expenditures, unnecessary invasive procedures and/or false-positive diagnoses, without certainty that the patients actually benefit from these imaging procedures. This review explores whether diagnostic imaging leads to better patient-reported outcomes in individuals with musculoskeletal disorders.

Method: Databases were searched from inception to September 2013, together with scrutiny of selected bibliographies.

Purpose: To evaluate the reliability and validity of the Dutch Shoulder Pain and Disability Index (SPADI-D).

Background: The SPADI is recommended and frequently used. However, the validity and reliability of the SPADI-D are unknown.

Study Design: Reliability study.

Objectives: The aim of this study was to evaluate the interrater-reliability of the interpretation of diagnostic ultrasound in patients with shoulder pain between physical therapists and radiologists.

Background: Although physical therapists in The Netherlands increasingly use diagnostic ultrasound in clinical practice, there is no evidence available on its reliability.

Background: Shoulder pain is disabling and has a considerable socio-economic impact. Over 50% of patients presenting in primary care still have symptoms after 6 months; moreover, prognostic factors such as pain intensity, age, disability level and duration of complaints are associated with poor outcome. Most shoulder complaints in this group are categorized as non-specific.
