Detailed Description
Shoulder pain is one of the common health problems. It ranks third among musculoskeletal problems after low back and neck pain. Subacromial Impingement Syndrome (SIS) is the most common cause of shoulder pain. SIS is a pathology resulting from mechanical repetitive compression and inflammation of the supraspinatus tendon, subacromial-subdeltoid bursa, and biceps tendon located under the acromion and coracoacromial ligament. SIS is characterized by functional limitation of the shoulder with gradual limitation of both active and passive glenohumeral movement due to compression of the subacromial structures. Pain in the anterior shoulder region, which is exacerbated by elevation of the shoulder joint or overhead activities, and limitation of range of motion are the main reasons for the decrease in quality of life in patients with SIS.
The most common symptom of SIS is pain. The pain is usually at night and radiates to the anterior aspect of the shoulder. Night pain often occurs when lying on the affected side and is typically in the deltoid region. Symptoms usually increase with abduction, elevation, or overhead activities. Patients often complain that they have difficulty reaching their back while dressing. Active movements may be restricted due to pain.
Analgesics and nonsteroidal anti-inflammatory drugs (NSAIDs), steroid injections, physical therapy methods, exercise and surgical procedures are used in the treatment of shoulder pain. Superficial hot and cold applications, analgesic currents, ultrasound, extracorporeal shock wave therapy (ESWT), magnetotherapy, laser and acupuncture are preferred as treatment options.
Magnetotherapy is a treatment method based on magnetic field interaction. As a result of pulsed or alternating electromagnetic fields, an electrical current occurs in the tissues. Pulse magnetotherapy has three physical mechanisms known to be effective in living tissue: Magnetic induction, magneto-mechanical effects, and electronic interactions. Effects of magnetic field application are vasodilation, analgesic effect, anti-inflammatory effect, acceleration of healing, antiedematous effect. Magnetotherapy increases the oxygen release of erythrocytes and provides oxygenation of the tissues. This causes a decrease in toxins in the damaged area, an increase in vital nutrients and endorphins. With this physiological change, magnetic energy decreases the pain receptor sensitivity that sends a message to the brain. With this treatment method, pain reduction is achieved, while joint mobility increases.
This study was designed as a double-blind, prospective, placebo-controlled, randomized study. Participants were randomized into 2 groups: PEMF + therapeutic exercise, sham PEMF + therapeutic exercise.
Shoulder range of motion, Visual Pain Scale (VAS), SF (Short form) -36 Quality of Life Scale, Constant Murley Scale, Shoulder pain and disability index, upper extremity muscle strength measurement with Isomed 2000 isokinetic device) will be evaluated. It was planned that the evaluations were made and recorded by a blinded physician to the groups at the beginning of the treatment, at the end of the treatment and at the 3rd month controls.

Arms and Interventions
Participant Group / Arm |
Intervention / Treatment |
---|---|
Experimental: PEMF+exercise
A total of 20 sessions of pulse electromagnetic field therapy using an electromagnetic field device (ASA Pmt Quatro Pro, ASA Srl Via A.Volta 9-36057, Italia), five times a week and once a day for four weeks, were applied to the patients.
The patients were then given a daily exercise program once a day by a physiotherapist.
|
It was applied with an electromagnetic field device (ASA Pmt Quatro Pro, ASA Srl Via A.Volta 9-36057 Italia) at 50 Hz frequency, 85 Gauss (8.5 milliTesla) intensity and for 30 minutes. The treatment period was 5 days a week for 4 weeks, in total. It was applied as 20 sessions. Therapeutic Exercise As a therapeutic exercise program; active shoulder ROM, isometric and progressive strengthening exercises for shoulder girdle muscles, codman pendulum exercises will be performed. It was planned to implement a total of 20 sessions 5 days a week for 4 weeks, for approximately 30 minutes. Exercises will be performed by a trained (at least 5 years experienced) physiotherapist, three times a day, in 3 sets, 10 repetitions. |
Sham Comparator: Sham PEMF+exercise
Sham therapy was applied in five sessions a week for four weeks, with a total of 20 sessions, with no current flowing through the device.
This was followed by the exercise programs described above, performed once a day with the physiotherapist.

What is the study measuring?
Primary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
---|---|---|
Change from baseline visual analog scale (VAS) shoulder pain rest movement at 4th and 12th week
Time Frame: up to 12th week
|
Pain intensity was measured with visual analogue scale for pain (0-10 mm; 0 means no pain, 10 means severe pain) which is used to measure musculoskeletal pain with very good reliability and validity.
|
up to 12th week
|
Secondary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
---|---|---|
Change from baseline quality of life (short form 36 (SF-36)) at 4th and 12th weeks
Time Frame: up to 12th week
|
This is a self-administered scale, which is widely used to measure the quality of life.
It was developed to measure the quality of life in patients who have physical illnesses; however, it can also be successfully used in healthy individuals and patients who have psychiatric diseases.
SF-36 includes 36 items and surveys eight domains of health, such as physical functionality, physical role limitations, pain, general health, vitality, social functionality, emotional role limitations, and mental health.
Total score was between 0 ( disability) and 100 (no disability).
Every subgroup of the questionnaire has a score scale between 0 and 100.
Every increase in the subgroup of SF-36 questionnaire, which is a positive scoring system, indicates increase in quality of life related to health.
|
up to 12th week
|
range of motion
Time Frame: up to 12th week
|
In shoulder range of motion measurement, flexion and abduction will be recorded, including active and passive measurements of the shoulder with a goniometer.Shoulder internal and external rotation measurements will be recorded while the patient's shoulder is abducted at 90 degrees and the elbow is flexed at 90 degrees.
|
up to 12th week
|
Change from baseline Constant Murley Score (C-MS) at 4th and 12th weeks
Time Frame: up to 12th week
|
The Constant-Murley Shoulder Score (C-M Score) is a clinical and functional assessment scale that evaluates the functional status of a normal, diseased or treated shoulder.
Comparisons can be made in pre-treatment and post-treatment follow-up.
Evaluated parameters were pain (15 points), activities of daily living (20 points), ROM (40 points), and strength (25 points).Scoring that measures the functionality of the shoulder consists of 100 points in total.
C-M score; It is classified as excellent (90-100), good (80-89), moderate (70-79) and poor (<70).
|
up to 12th week
|
Change from baseline Shoulder Pain and Disability Index(SPADI) at 4th and 12th weeks
Time Frame: up to 12th week
|
It is a two-part scale that evaluates pain and function.The first part questions pain, the second part questions disability.
In the pain section consisting of 5 items, the pain felt during activities of daily living is measured using a 10-unit VAS, and in the disability section, the difficulty encountered during activities of daily living is measured in the 8-item disability section.
The score of both sections and the total score are calculated with a special formula.
|
up to 12th week
|
Change from baseline upper extremity muscle strength with isokinetic device at 4th and 12th weeks
Time Frame: up to 12th week
|
Isokinetic contraction; It is defined as contraction at a constant rate throughout the entire range of motion and at an equal rate at all angles of motion.
No matter how hard a person moves the device, they can never exceed the predetermined speed (for example, 90 degrees per second).
It is advantageous that the desired muscle or muscle groups can be evaluated in isolation and that the measurements are comparable.
The isokinetic strength assessment of the patients during internal and external rotation of the shoulder will be made with an isokinetic device (IsoMed 2000, isokinetic dynamometer, Germany).
Measurements will be made by a physiotherapist with at least 5 years of device experience.
Measurements will be made in 10 repetitions to increase reliability.

up to 12th week
