Characteristics of Participants and Nonparticipants in a Blended Internet-Based Physical Activity Trial for Breast and Prostate Cancer Survivors: Cross-sectional Study.

Background: As the number of cancer survivors is increasing, it is important to be able to offer exercise and physical activity (PA)-promoting interventions that are both effective and reasonably accessible. Internet-based interventions are typically less expensive and more accessible alternatives to on-site supervised interventions. Currently, little is known about the characteristics of nonparticipants in PA promotion trials in the cancer survivorship setting, both in general and specifically in trials using internet-supported interventions.

Eccentric versus conventional exercise therapy in patients with rotator cuff tendinopathy: a randomized, single blinded, clinical trial.

Purpose: To investigate the effectiveness of isolated eccentric versus conventional exercise therapy in patients with rotator cuff tendinopathy.

Methods: Thirty-six patients with rotator cuff tendinopathy, diagnosed by an orthopaedic surgeon, were included and randomly allocated to an isolated eccentric exercise (EE) group (n = 20, mean age = 50.2 ± 10.

A feedback protocol improves the diagnostic performance of MR arthrography by experienced musculoskeletal radiologists in patients with traumatic anterior shoulder instability.

Purpose: To prospectively evaluate the diagnostic performance of magnetic-resonance-arthrography (MRA) by experienced musculoskeletal radiologists in patients with traumatic-anterior-shoulder-instability (TASI), after feedback protocol execution.

Materials And Methods: Forty-five surgically confirmed MRA's were used to enhance personal feedback, to discuss differences in outcome between MRA assessment and surgical findings and to fine-tune definition interpretation agreement of 7 different TASI-related lesions, between experienced musculoskeletal radiologists and experienced orthopaedic shoulder surgeons. After execution of the feedback protocol 20 new, surgically confirmed, MRA's were assessed by 2 experienced musculoskeletal radiologists using a seven-lesion standardized scoring form.

Are radiologists superior to orthopaedic surgeons in diagnosing instability-related shoulder lesions on magnetic resonance arthrography? A multicenter reproducibility and accuracy study.

Background: We compared the diagnostic reproducibility and accuracy of musculoskeletal radiologists with orthopaedic shoulder surgeons in 2 large medical centers in assessing magnetic resonance arthrograms (MRAs) of patients with traumatic anterior shoulder instability.

Methods: Forty-five surgically confirmed MRAs were assessed by 4 radiologists, 4 orthopaedic surgeons, 2 radiologic teams, and 2 orthopaedic teams. During MRA assessment and surgery, the same 7-lesion scoring form was used.

Hemiarthroplasty for humeral four-part fractures for patients 65 years and older: a randomized controlled trial.

Background: Four-part fractures of the proximal humerus account for 3% of all humeral fractures and are regarded as the most difficult fractures to treat in the elderly. Various authors recommend nonoperative treatment or hemiarthroplasty, but the literature is unclear regarding which provides better quality of life and function.

Questions/purposes: We therefore performed a randomized controlled trial to compare (1) function, (2) strength, and (3) pain and disability in patients 65 years and older with four-part humeral fractures treated either nonoperatively or with hemiarthroplasty.
