Background: We prospectively tested technical feasibility and clinical outcome of percutaneous ultrasound-guided tenotomy of long head of biceps tendon (LHBT). Methods: We included 11 patients (6 women; age: 73 ± 8.6 years) with symptomatic full-thickness rotator cuff tear and intact LHBT, in whom surgical repair was not possible/refused. After ultrasound-guided injection of local anesthetic, the LHBT was cut with a scalpel under continuous ultrasound monitoring until it became no longer visible. Pain was recorded before and at least six months after procedure. An eight-item questionnaire was administered to patients at follow-up. Results: A median of 4 tendon cuts were needed to ensure com…

Should Exercises be Painful or not? Effects on Clinical and Experimental Pain in Individuals with Shoulder Pain

2021

Exercise can reduce pain, however the effect of painful versus non-painful exercises is uncertain. The primary aim of this randomized crossover study was to compare the effect of painful versus nonpainful isometric shoulder exercises on pain intensity after exercise in individuals with rotator cuff-related shoulder pain. Secondary exploratory aims were to describe the effects on pressure pain thresholds (PPTs), conditioned pain modulation (CPM) and muscle strength. On separate days, 35 individuals performed painful isometric shoulder exercises (external rotation; 20% above pain threshold), nonpainful isometric shoulder exercises (external rotation; 20% below pain threshold), and a rest cond…

Computed tomography-based tracheobronchial image reconstruction allows selection of the individually appropriate double-lumen tube size

1999

Objectives: To determine whether individualized selection of double-lumen tubes or alternatives based on three-dimensional reconstruction of the tracheobronchial image from routine preoperative computed tomography (CT) scans leads to clinically appropriate choices. Design: Prospective observational study; comparison to historic controls. Setting: Anesthesia and radiology facilities of a university medical center. Participants: Forty-nine patients undergoing thoracic surgery requiring one-lung ventilation. Interventions: Three-dimensional image reconstruction of individual tracheobronchial anatomy was performed from routine preoperative spiral CT scans as well as from scans of five left-side…

Reproducibility of isometric strength: measurement of neck muscles

1999

Abstract Objective. To evaluate the repeatability of an advanced method of measuring the strength of functionally different groups of neck muscles using an isometric apparatus. Design. A repeated measures design was used within and between sessions. Background. Chronic neck pain has been associated with poor isometric neck strength. In rehabilitation, strength measurements may thus help to evaluate the basic condition and show whether or not treatments and exercises have been beneficial for improving strength. Previous tests have concentrated on testing strength while trying to bend forwards and backwards, but no biomechanics device, able to test rotator muscles, has been presented. Method.…

Feasibility of cuff-free measurement of systolic and diastolic arterial blood pressure

2011

We validated a prototype cuff-free device for noninvasive estimation of blood pressure (BP). The system assumed a linear relation between BP values and the inverse of arterial blood pulse transit time, measured as time interval between the R wave on the electrocardiograph and the onset of the peripheral pulse wave on a finger plethysmogram. Thirty-three healthy subjects were analyzed at rest and during increasing stress exercise. To estimate subject-specific linear model parameters, the system was calibrated ad personam with reference to BP measures obtained by a cuff sphygmomanometer. High correlation values (R2= 0.89 and 0.78 for systolic and diastolic BP, respectively) and differences co…

Chronic sacral spinal nerve stimulation for fecal incontinence: long-term results with foramen and cuff electrodes.

2002

PURPOSE: Sacral spinal nerve stimulation is a new therapeutic approach for patients with severe fecal incontinence owing to functional deficits of the external anal sphincter. It aims to use the morphologically intact anatomy to recruit residual function. This study evaluates the long-term results of the first patients treated with this novel approach applying two techniques of sacral spinal nerve stimulator implantation. METHODS: Six patients underwent either of two techniques for electrode placement: one “closed” (electrodes placed through the sacral foramen) and one “open” (cuff electrodes placed after sacral laminectomy). Follow-up evaluation of their continence status ranged from 5 to …

The relationship between functional disability and health-related quality of life in patients with a rotator cuff tear

2012

To determine the relationship between functional disability and health-related quality of life (HRQoL) in rotator cuff tear (RCT) patients.In 67 RCT patients (mean age, 54 years; 57% males), functional disability was self-reported with the American Shoulder and Elbow Surgeons Standardized Shoulder Assessment Form (ASES), HRQoL with the Short-Form 36 Health Survey (SF-36), and pain by visual analogue scale. ASES results were divided into tertiles (12-38, 39-51, and 52-82).Mean ASES score was 48 (range, 12-82). Patients with the highest functional disability and highest pain level had the lowest HRQoL. For the highest, middle, and lowest ASES categories, respectively, mean SF-36 Physical Comp…

Lesioni funzionali della cuffia dei rotatori; ruolo del “rotator cable” e del “rotator crescent”

2011

OBIETTIVO DIDATTICO. Descrivere due importanti componenti anatomiche del tendine del sovraspinato, il “rotator cable” ed il “rotator crescent”, ed il loro ruolo nelle lesioni della cuffia. Valutare le importanti implicazioni biomeccaniche e cliniche attribuite a questa struttura e la correlazione negativa tra "lesione della cuffia" e quadro clinico in termini di dolore e impotenza funzionale. INTRODUZIONE. La cuffia dei rotatori è un complesso funzionale composto da muscoli e tendini che provvedono a mantenere stabile la spalla. Il tendine del sovraspinato ne rappresenta la componente principale, e nel suo contesto si trova uno spesso gruppo di fibre perpendicolari al suo asse, descritto pe…

Matlab-based interface for the simultaneous acquisition of force measures and Doppler ultrasound muscular images

2012

This paper tackles the design of a graphical user interface (GUI) based on Matlab (MathWorks Inc., MA), a worldwide standard in the processing of biosignals, which allows the acquisition of muscular force signals and images from a ultrasound scanner simultaneously. Thus, it is possible to unify two key magnitudes for analyzing the evolution of muscular injuries: the force exerted by the muscle and section/length of the muscle when such force is exerted. This paper describes the modules developed to finally show its applicability with a case study to analyze the functioning capacity of the shoulder rotator cuff.
