Pressure Pain Sensitivity is Independent of Structural Pathology in Patients with Subacromial Pain Syndrome: A Cross-Sectional Analysis.

Objective: To compare localized (primary) and widespread (secondary) hyperalgesia using pressure pain threshold (PPT) of patients with normal imaging findings, rotator cuff tear, or other pathologies.

Design: This was a cross-sectional design with data collected at a single time point.

Setting: This study was performed at two large, urban, academic medical centers.

Peripheral Nerve Stimulation of the Axillary Nerve Improves Chronic Shoulder Pain and Dysfunction Following Reverse Total Shoulder Arthroplasty: A Case Report.

Reverse total shoulder arthroplasty (rTSA) is an effective procedure to improve shoulder pain, range of motion, and function for a variety of conditions, including glenohumeral osteoarthritis and rotator cuff arthropathy. However, up to 22% of patients have persistent shoulder pain 12 to 24 months following rTSA, even in the absence of surgical complications. Currently, there are no widely accepted non-pharmacological treatments for persistent postoperative pain after rTSA.

Changing Stimulation Frequency Improves Implanted Peripheral Nerve Stimulator Effects After Posttraumatic Total Hip Arthroplasty: A Case Report.

Total hip arthroplasty is an effective procedure to improve pain, range of motion, and function for a variety of conditions, including osteoarthritis and posttraumatic arthritis. Up to 28% of patients had persistent pain at the surgical site 12-18 mos after total hip arthroplasty, even in the absence of surgical complications. Currently, there are no widely accepted nonpharmacological treatments for persistent postoperative pain for total hip arthroplasty.

Emerging Role of Quantitative Ultrasound-Based Imaging Techniques for Characterizing Rotator Cuff Tears: A Scoping Review.

Rotator cuff myosteatosis following cuff tears is very common and one of the most important prognostic factors in clinical management. Quantitative ultrasound-based imaging techniques (QUBIT) are frequently used along with magnetic resonance imaging (MRI) to evaluate rotator cuff fatty degeneration. However, the examination of rotator cuff tissue integrity by QUBIT is lacking a standardized imaging protocol and procedural methodologies.
