Magnetic Resonance Imaging Parameters in Patients with Subacromial Impingement Syndrome

Relationship of Magnetic Resonance Imaging Parameters with Shoulder Function and Pain in Patients with Subacromial Impingement Syndrome

Shoulder pain is the third most common musculoskeletal pain complaint in the world with an incidence of 7-30%. Subacromial impingement syndrome (SIS) is the most common cause of shoulder pain. Imaging in impingement syndrome is usually based on different imaging modalities. X-ray, magnetic resonance imaging (MRI) and ultrasound are the most commonly used, and MRI is considered by many authors to be the most reliable imaging modality for evaluation of the rotator cuff because it allows evaluation of soft tissues as well as bony abnormalities such as subacromial osteophytes and acromioclavicular joint capsular hypertrophy. MRI allows the diagnosis of rotator cuff tears with greater interobserver reliability than ultrasound in assessing tear size, retraction and atrophy. Few studies have investigated the impact of pathologic findings on MRI on the degree of symptoms and functional impairment seen in these patients. The aim of this study was to investigate the relationship between shoulder pain and function and MRI findings in patients with subacromial impingement syndrome.

Study Overview

• Status: Not yet recruiting
• Conditions: Subacromial Impingement Syndrome

Detailed Description

In this clinical study, 100 patients who were admitted to Fatih Sultan Mehmet Training and Research Hospital Physical Medicine and Rehabilitation outpatient clinic with shoulder pain and diagnosed with subacromial shoulder impingement by routine laboratory and imaging tests will be included in this study. Demographic data such as age, gender, body mass index, education, occupation, comorbidities, smoking, alcohol consumption will be recorded. Pain intensity will be assessed by Visual analog scale (VAS) and function will be assessed by Shoulder Pain and Disability Index (SPADI).

Pain Assessment: The VAS is a one-dimensional measure of pain intensity and is commonly used in adult populations including rheumatologic patients. It can be used horizontally or vertically. The patient marks his/her own pain on a 10 cm ruler with no pain at one end and the most severe pain at the other end. In this method, the patient is told that there are two extremes and that he/she is free to mark any point between these points.

Functional assessment: All patients will be assessed for shoulder function using the Shoulder Pain and Disability Index (SPADI) The SPADI is a self-administered questionnaire that includes two dimensions, one for pain and one for functional activities. In the pain dimension, there are five questions about the severity of an individual's pain. Eight questions assess functional activities designed to measure the degree of difficulty an individual has in performing various activities of daily living that require the use of the upper limbs. Patients are asked to place a 10 cm mark as the answer to each question.

Shoulder joint range of motion: Participants' shoulder range of motion (ROM) active and passive flexion, abduction, internal and external rotation will be examined with a goniometer.

Magnetic resonance imaging: All MRI scans will be reviewed by an independent radiologist specializing in musculoskeletal imaging who is unaware of the patients' clinical data. Each MRI scan will include at least one transverse, sagittal and coronal plane consisting of at least one T1-weighted and at least one proton density (PD) weighted or T2-weighted fat-suppressed sequence. All MRI parameters will be electronically evaluated using a PACS workstation (SimplexBT PACS, Ankara Universitesi Teknokent, Ankara, Turkey).

Primary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Pain	Pain Assessment: The visual analog scale is a one-dimensional measure of pain intensity and is widely used in adult populations, including rheumatologic patients. It can be used horizontally or vertically. The patient marks their pain on a 10 cm ruler with no pain at one end and the most severe pain at the other. Patients are asked to rank their pain intensity on a 10-point scale, where 0 = no pain, 5 = moderate pain and 10 = unbearable pain. In this method, the patient is told that there are two extremes and that they are free to mark any point in between. A higher value indicates more severe pain.	2 months

Secondary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Function	Functional assessment: All groups will be assessed for shoulder function using the Shoulder Pain and Disability Index. The Shoulder Pain and Disability Index includes two dimensions, one for pain and one for functional activities. Patients are asked to describe the extent of their shoulder problems by marking a number on a scale from zero (no pain or disability) to ten (maximum pain and disability) for each item. The results from each subscale are then summed and converted into a score out of 100. A minimum score of 0 and a maximum score of 100 can be obtained. The higher the final score, the greater the shoulder pain, impairment or disability.	2 months
